Sigma 100-300mm f/4 EX DG IF HSM APO Fast Aperture Telephoto Zoom Lens for Sigma SLR Cameras Review

Sigma 100-300mm f/4 EX DG IF HSM APO Fast Aperture Telephoto Zoom Lens for Sigma SLR Cameras

I bought this lens to use with my Canon 30D for high school sports (soccer, football, baseball, etc). I already had the Sigma APO 70-200mm f/2.8 EX DG HSM Lens for Canon Digital SLR Cameras and needed more focal length. Like the 70-200 F/2.8, this lens is big, heavy, and built like a tank. The bare lens is about an inch longer than the 70-200, but the 100-300's hood is longer than the 70-200's hood.
The zoom and focus rings are wide and move smoothly with just the right amount of resistance. This lens is sharp wide open. At the overlapping focal lengths, the 70-200 at F/4 is just barely sharper than this lens at F/4 (wide open). At 200mm, this lens is actually sharper (200mm is this lens's sweet spot.) At 300mm, the lens is still sharp wide open, but I like to stop down to F/4.5 just to keep things super-sharp. Up to 250mm, I would not hesitate to use it wide open.
This Sigma lens has HSM which means the focus is fast and quiet. The lens focuses a little slower than the 70-200 F/2.8, but I've found that the 30D is more of a limiting factor in focus speed than the lens is. Servo tracking is very good with this lens, the only time it can't keep up is when track runners are sprinting straight at me (although again, I think the body is the limiting factor here.) For almost every other situation, the focus will definitely keep up.
All in all, this is not an indoor lens by any means, but as an outdoor sports (or wildlife/nature) lens, it is awesome.

This telephoto zoom lens provides a large F4 aperture at all focal lengths. With minimal light-fall-off, superior peripheral brightness is ensured. It's the ideal lens for digital SLR cameras.The new multi layer lens coating and lens design reduce flare and ghost, which is a common problem with digital cameras and also creates an optimum color balance through the entire zoom range.This lens uses two pieces of SLD glass elements in the front lens group and another two in the rear group for excellent correction of chromatic aberration. High optic performance is demonstrated throughout the entire zoom range.This lens incorporates an internal focusing system, which eliminates front lens rotation, allowing the use of a Petal-type Hood and more convenient to use of circular polarizing filter. Since focusing and zooming do not change its overall length, this lens is easy to hold and use.The use of an Apochromatic design and 4 SLD (The Special Low Dispersion) glass elements (two SLD glass elements are utilized in the front lens group and two in the rear group) provide for full correction of chromatic aberration and a high level of optical performance.The DG designation applied to certain newer Sigma lenses (mostly wide-angle and wide zoom type lenses) indicates that the lens is especially suited for use with digital SLR cameras. The DG lenses feature improved (more even) light distribution from image center to edge, especially at maximum aperture, compared to conventional fast wide-angle lenses. This is important in digital photography, but is also useful in 35mm photography, especially when slide film is used. Also, the shorter focal lengths are desirable, because most digital SLR cameras have image sensors whose dimensions are considerably smaller than a 35mm negative (usually by a factor of 1.3X to 1.7X), making the lens' angle of view equivalent to that of a longer lens on a 35mm camera.

The Sigma 300 F2.8 lens for Sony/Minolta is a great lens for the price. I could not afford The Sony/Minolta equivalent as it was over twice the price. The color,contrast and resolution of this lens is excellent and works great with 1.4 and 2.0 Sigma teleconverters. It also works great with the in-camera image stabilization on the Sony DSLR cameras.

I received the Sigma 17-70 2.8-4 OS HSM from Amazon five days ago. I have taken about 400 shots with this lens, including landscapes, indoor family gatherings with flash, and a sporting event in a large, well-lit indoor arena. It seems to me that this lens works as advertised. I don't see focus problems with this lens in either the AI Servo to AI Focus modes on my Canon XSi. The XSi exposure metering seems to work fine with the Sigma 17-70, and I cannot see anything wrong with color accuracy. The finish, appearance, and feel of the lens are pleasing. I like it, and it certainly seems to be a good value given its relatively low cost vs. function. I have awarded four stars in my rating only because of my limited experience with this lens. If this lens continues to work as it has so far, I would award a fifth star.
Photography is my hobby, not my profession, but I carry my camera to work and shoot nearly every day. I cannot afford high-end camera equipment, so I make do with what I can afford. Even so, I have had rewarding successes and lots of fun with my hobby. My photos have been published in magazines, textbooks, brochures, large-format calendars, and web sites. They have been framed and hung on walls in office suites, sports arenas, and homes.
I have used Sigma lens for the past ten years, and currently own four Sigma lens for my Canon XSi. Sigma lens are cheap, they are most often lightweight as compared to Canon lens, and they work acceptably well. I am familiar with the "you get what you pay for" concept, and I understand that sometimes there are issues with Sigma lens. I can see why professionals need sturdy equipment, but overall Sigma has provided me with a successful and cost-effective way to observe, record, and enjoy my surroundings.

To echo what is said about the new release SIGMA lenses - WOW.
Canon look out. I was shopping for a new toy for XMAS and settled on the CANON 14mm F2.8L lens. It was very nice but for the price hard to justify. I asked for an eval of the Canon and this, the Sigma alternative at 1/3rd the price. Head to head testing of the lenses on my Canon EOS 50 (ELAN) using ISO 200 film resulted in the Sigma producing a crisper image with better definition and colour saturation. Both lenses have a little "flattening" of the image at the edges as they try to compensate for curvature but the Sigma in my opinion is closer to true. Neither lens had any trouble Auto-Focusing during the day (Canon felt a little faster). The Sigma was a little unsure of itself on when I went for a night/bulb exposure of the starscape. Switched to Manual, set for infinity and away we went. My only other issue with the Sigma is the lens hood is not quite big enough where the Canon is spot on. Still you have to be looking really hard for faults to find them.
Tooling around with the lens has been lots of fun. I had never considered using the lens for indoors shots but it is magic. Architecture photography is going to be a new thing for me I think.

I purchased Tamron AF 70-300mm LD lens for Canon over a month ago. The first roll of film was a bit of disappointing. I liked colors but some pictures lacked sharpness (fuzzy). After that I purchased introduction photography book published by Kodak and read it. Gained knowledge was invalueable. I used tripod and Kodak Gold 200 color print film. Pictures were developed on 5x7 photographs at York Photo Labs. All pictures of second roll turned out very nice and sharp (especially considering 200 film on 5x7 pictures). I even made picture of caterpillar in macro mode at 300 mm and f/8 and this turned out very nice as well. All pictures (including ones taken at focal length of 300 mm) turned out very nice. Ultra telephoto lens is demanding but wide-angle lens is forgiving. You have to consider it when you use telephoto lens. You need solid technique; otherwise, you might be disappointed if you take handheld pictures with lower shutter speeds. It is pretty hard to make sharp pictures even at 1/250 shutter speed and 200mm. Tripod works well though. The larger focal length the harder it gets. I would not feel comfortable with anything slower than 1/250s. Some people mentioned that f/8 gives better results. That is true pretty much for any lens. But at this aperture you need tripod when using ISO 100 films unless you are in sun. If you can't use tripod but you want to use this lens then you might use faster films (IS0 200 or ISO 400) to reduce camera shake. Build quality is good and great warranty gives you peace of mind. Customer service is quick too (don't worry my lens is not broken but I had some technical questions to Tamron). This lens is also sold as Nikon AF 70-300mm ED and users seem to enjoy it as well (even though they pay 100$ more). Focusing is kind of slow, especially in low-light conditions and at larger focal lengths (i.e. 300 mm). You can't blame lens for it because camera does focusing. At this low amount of light and narrow angle (7 degrees - camera gets not much lights through lens). It is not Tamron but nature of telephoto lens. This is why camera haunts in low-light conditions. Lens comes with lens hood (lens shade) so you don't have to buy one for this lens. Overall, I am very pleased with pictures and expect even better pictures on ISO 100 films and 4x6 prints. Use tripod as much as possible. Also cable release is recommended to reduce camera shake. Great lens for the money. Period.

This is the definitive lightweight, compact telephoto macro zoom with a maximum magnification ratio of 1: 2 at the 300mm setting - ideal for shooting subjects that are difficult to approach such as sporting and theatrical events. The lens also features special effects such as the capability to provide beautifully blurred backgrounds to highlight the main subject in portraiture, or "compression effects" that make the most of the telephoto lens. By switching to macro mode, subjects as close as 0.95m can be shot within the focal range of 180-300mm, for true macro photography. The optical system incorporates a LD (Low Dispersion) lens, resulting in clear sharp images free of chromatic aberration.Type of zooming is rotation.

I bought this lens off of ebay for a very good price. I needed a prime for my wildlife shots. On a D300, it performs top notch. It focuses fast, even slightly faster than my 70-300mm VR even though it's non AF-S. Another important thing is that the focus dead on! It never seems to back or front focus, it knows where to go and rarely hunts. Results may be different if you're using a camera less than at least a D300. The only reason I gave it four stars is because it cannot be used with Nikons TC's. It won't AF on a D40,40x or 60.
If you're considering it and have a camera body that can handle it, get it.

Sigma 20mm f/1.8 EX DG RF Aspherical Wide Angle Lens for Sigma SLR Cameras Review

Sigma 20mm f/1.8 EX DG RF Aspherical Wide Angle Lens for Sigma SLR Cameras
Average Reviews:

(More customer reviews)
I have used this lens extensively with the 1D and the Rebel XT. Results have been excellent. My suspicion is that the previous reviewer got a defective or damaged copy of the lens. It is incredibly sharp, even at f1.8, which I did not expect - generally you expect a lens to be a bit soft wide open, especially 1.8. The degree of sharpness of this lens is quite surprising.
I have used, for example, both the Canon 50mm f1.8 and the Canon 35mm f2.0, both of which are deservedly renowned for their sharpness and contrast. I find this lens to be sharper than either of them wide open. The lens provides images which have excellent color saturation and contrast. Of course, at f1.8, depth of field is razor thin, by design, which is great for bokeh or out of focus background, but which also requires care concerning the desired focal point being in focus. Speaking of bokeh, I find it to be very attractive compared to any other lens I have used.
Its minimum distance focusing is also quite remarkable. I think it is rated at just under 8 inches, but I routinely focus at distances which seem a good bit closer than that. The lens works well as a macro for many applications, with a relatively strong multiplication factor.
Of course, given the inherent light-gathering of a 20mm focal length lens, combined with a huge aperture of f1.8, this lens is outstanding for shooting indoors or in other low-light situations with natural light and no flash.
Canon's nearest competitor to this lens is the 20mm f2.8, which is a full stop slower in terms of light collection. I consider this lens to be an extremely good value at the retail price, new. If you can get a good copy used on-line, it will be an incredible value. You may find that you never want to take the lens off the camera because of its versatility as a walkaround lens.
This lens has been extremely well-reviewed, by and large, on lens forum sites. I encourage you to check those out. Most people rate the lens 5 out of 5. A distinct minority give it 1 out of 5. I suspect that they either have defective copies which may need repair, or they have inaccurate perceptions of the lens. Also, popular photography magazine online reviewed this lens, as well as the 24 f1.8 and the 28 f1.8, very highly.
I would highly recommend this lens to anyone who wants a fast, sharp superwide angle lens.

Detailed DescriptionThe UV filter is one of the most important filters to own and it should be available for every lens. The filter blocks the invisible UV rays which can cause a loss of sharpness. The use of the filter is particularly recommended for work in the mountains, at the ocean, and in areas with very clear air. The contrasts are heightened, and distorting fog is avoided. The Opteka HD² Multi-Coated UV (0) Ultraviolet Haze Filter cuts haze for sharper black and white prints and corrects the blues and violets in color prints. The filter glass is colorless, and hence no increase in the exposure time is required.Multi-coating can prevent light reflection, ghost light, internal reflection etc, making image clearer and sharper. It can dramatically improve image quality. This is specially important in digital cameras. Since the image sensors CCD or CMOS are highly susceptible to reflections, this stray light can ruin your photographs. Multi-coated glass benefit substantially reduced light reflections, resulting clearer image with greater contrast.This type of filter is also eminently suitable as protection for the front lens, and because of its color-neutral properties it can remain on the camera lens permanently. A scratched front lens element can not be repaired; and replacement is costly. Exchanging a damaged UV filter for a new one is more economical than the purchase of a new lens.

I have only had 2 days to play with this lens, but so far am impressed with it's performance. I bought this mainly for outdoor use as I have a Nikon 70-200 f2.8 VR lens for indoor shooting. I simply do not want that mammoth lens on my camera when hiking, etc., especially since fast aperture is not necessary in good light. This one looks like it will do nicely. Focus is pretty fast - hunts a little in lower light at telephoto, but that's pretty common for most lenses of this type. Image quality is very good so far. Some very minor fringing in a few of the shots (not an issue with JPEG's from my D90 because it automatically removes most CA). I'll shoot some RAW shots outdoors when I get a chance to see if it is anything to worry about, but so far it appears to be acceptable. Focus is extremely accurate - dead-on on every shot taken (no front focus issues that some Sigma lenses have). OS is also VERY impressive. I'd say really close to Nikon's best VRII lenses. I took a couple of 1/4 sec. shots handheld with only my elbows braced against my ribs, at full telephoto, and the shots were perfectly sharp. You can see the image start to float when the shutter is half-pressed, so you know the stabilizer is working. Lens mounts snugly onto the camera and has a good, sturdy metal mount like the better Nikon lenses have. Fits perfectly. I like the size and weight compared to the Nikon equivalent (it is somewhat more compact). The only drawback is that the lens is not internal focusing like the Nikon (which probably accounts for the compactness). This means that the lens hood must be a round one (not a petal hood, which I prefer) because the end of the lens rotates as it focuses. It also extends about 7/8 of an inch at closest focus, which makes the overall length pretty long at 300mm (about 8 inches without hood, around 10 with the hood attached). None of that really matters much to me, though. One thing that I liked about this one compared to the Nikon 70-300 VR was that the aperture starts at f4, not f4.5, so it's a bit faster than the Nikon. The shallow depth of field was surprising to me. Longer focal lengths tend to really amplify the effect at closer ranges, and that is very apparent with this one.
The best way to rate this lens would be to break down specific attributes, and then give a score (1 to 10) on that attribute, so here goes:
Image quality (so far): 9 (impressed with every one taken thus far - color, sharpness, etc. quite good)
Focus accuracy: 9 (low light the only issue)
Focus speed: 8 (could be a little better)
Focus noise: 7 (not as quiet to focus as Nikon AF lenses - even my huge 70-200 f2.8 VR lens is lots quieter)
Fit: 10
Finish quality: 7 (surface not as good looking or durable looking as Nikon, but not ugly either)
Optical Stabilization: 9.5
Size/weight: 9
Overall ease of use/functionality: 9
I will update with more information after using the lens more. I cannot give the lens 5 stars, although I believe it is not far from achieving that. I think most people will agree that this lens is worth the money spent and will do what it is intended to do, and do it well.
Update: Feb. 2010- Have taken a few more shots with this lens. All-in-all still very satisfied with it. The fringing noted earlier is there - a bit more than I first indicated. RAW shows slightly more than the JPEG's, but it is fairly easy to remove the majority of it in Lightroom. Some images look a bit soft. When I compare them to the 18-105 Nikon kit lens, I initially thought they were pretty comparable,but they are a tad bit softer when looked at closely. It is much softer than my 70-200 f2.8, even when that one is shot wide open - and the Sigma is FAR behind on anything stopped down to f4 or higher on the Nikon. However, I would expect nothing less from a lens that is over 5 times as expensive. Outdoor shots are very respectable from the Sigma - It is my recommendation that a person use this lens stopped down some outdoors, particularly at 200mm and above, as the fairly shallow depth of field when zoomed will render some subjects in front of the main subject out of focus, even on relatively distant shots. F8 to f11 fixes that most of the time. My initial rating of 4 stars still stands, as I feel that image quality is less than perfect, but as good as anyone should expect at this price level. The only individual rating that would change is the image quality that I rated a 9, is more like an 8 - still pretty good. Is is considerably better than a Nikon 55-200 VR that I sold recently - it was soft across the frame, with a very bad left side. Perhaps a bad copy? Anyway, the Sigma 70-300 OS is a lens I am proud to carry in my gear bag, and one that will work well for me for a long time.
Update 2: Mar. 2010 - Upon further inspection of the images, it appears that shots taken stopped down some are a fair bit sharper than when shot wide open. Stopped down shots look to be sharper than just about any of the Nikon 18-105 ones, but are softer than the Nikon when shot wide open. That being said, my recommendation in a sentence or two is: shoot this lens stopped down a bit and don't expect to use it in low light without flash or for indoor sports. The best shots will result from the lens set too slow to be of much use in those cases. If I have more to report, I will do so later.

Heliopan makes great filters and the SH-PMC is the top of the line. If you are serious about photography and have spent hundreds or thousands on your equipment, why be cheap when it comes to a UV filter which everyone should have? This is the gold standard of UV filters and it is worth the extra money to have the best. I am very satisfied with this product.

The Heliopan 67mm UV SH-PMC Filter is not only an excellent filter for visually improving images made with either digital camera or shot on film, but it can always stay on the lens to protect the lens from fingerprints, dust, and moisture. It absorbs the short wave portion of the spectrum so in hazy conditions a better image of the scene is possible. Loss of sharpness from ultraviolet rays and the blue tones common in infinity scenes are eliminated. No exposure correction is needed.

Voigtlander Nokton 58mm f/1.4 SL-II Manual Focus Lens for Pentax Film & Digital Cameras Review

Voigtlander Nokton 58mm f/1.4 SL-II Manual Focus Lens for Pentax Film and Digital Cameras
Average Reviews:

(More customer reviews)
The Voigtlander Nokton 58mm is made by Cosina in Japan. On Pentax DSLRs, it is equivalent to an 87mm lens - a very useful focal length for portrait photography. The lens is all-metal, but its online photographs don't really do it justice - it's a real pleasure to hold and control, but you wouldn't be able to tell that just from looking at its photos. Build quality is in the same class as the Pentax Limited series - at 380$ (price as of August 2009), that makes it quite a bargain, given that few of the Pentax Limited sell for less.
The Nokton is a manual focus lens, which doesn't bother me at all, as I rarely use AF, but YMMV here. The focus ring is smooth and allows very accurate control - it's a real pleasure to use. Aperture can be controlled in camera, so the aperture ring is not something you'll need to use (just set it to A). Some reviews mentioned that the exposure is not determined correctly, but so far, I have no complaints in this area - the exposure was always set correctly for the photos I shot. You will have to enter the focal length when starting the camera, because the Pentax DSLRs won't recognize the Nokton - I just selected 55mm, as that was the closest option available.
As far as sharpness goes, this is a very sharp lens - you'll be hard-pressed to find a sharper lens regardless of price and it's the kind of sharpness that can convince one to prefer prime lenses over zooms. I am very pleased with the bokeh as well.
Pros:
- useful focal length
- superb quality all-metal build
- fast and sharp
- buttery bokeh
- excellent focus ring
- great quality-price ratio
Pros/Cons depending on how you look at it:
- MF only - bad if you want AF, good if you like MF (AF lenses just don't control like this)
Cons:
- need to set focal length when starting camera

I wish I would have started out with Rodenstock for my filter collection. Their filters are very high quality, the glass is clear, the rings are brass, and they are very easy to clean. Very Nice product.

Letus Mini Review

I love this adapter. I have had fun shooting video that looks more like film with smaller HD cameras with this adapter. You can see samples on Vimeo.
Overall the Letus Mini requires not much more than focusing and remembering to turn on the adapter motor, which runs on 2 AA batteries. Other adapters require you to purchase other "flip" devices or to flip your picture in post, which means you have to view/record your image upside down.
At first I tried to use it without support rails, that was a bad idea. The Letus Mini while small, is almost as heavy as my camera so I didn't want that much weight hanging off the front of my camera unsupported. The plastic threads on my camera had me a little bit worried about the whole set up, so I got the rails afterall.

I have a bunch of 55mm filters from an older camera but I needed them to fit a lens with a 52mm thread. This did the trick. It's made of metal and I haven't had any trouble getting it on or off.

Allows you to use larger size filters on lenses with a smaller diameter thread. The first number is the size that screws into the lense, the second number is the filter size.

Very good product, I just have one concern, what the differences are between the large pens? I love all of them, plus I got to give a couple away because they seem redundant.. For the price I would buy this one again because I can make a few brownie points with friends by giving away a few of the redundant ones. The single pen is only a few dollars cheaper, so grab this one and have a lens pen for each camera bag you have!
