Canon EOS Rebel Ti 35mm SLR Kit w/ 28-90mm Lens Review

Canon EOS Rebel Ti 35mm SLR Kit w/ 28-90mm Lens

As a dentist, I take a lot of intraoral (macro) photographs. I have a Minolta X570 as my main camera and recently added the Canon Rebel Ti. I agree with the user who recommended that you read the manual several times -- it took me three "reads", with the camera in front of me, to really grasp the "creative modes" -- but the effort is well worth it. Yes, you can use the camera forever on the fully automatic mode, but learn (at least) the following:
-- AEB (auto exposure bracketing): the Rebel Ti will take one shot at exact metering, then one shot stopped down and up (you decide the bracket range). One of them will be the "money" shot.
-- multiple exposures: it sounded hokey to me initially, but the ability to superimpose images is fun to experiment with and yields surprisingly good results.
A-DEP (automatic depth of field): this one is worth the price of admission! When subjects are at various focal lengths from the lens, use this feature. The Canon's brain will determine the nearest subject and farthest subject (as covered by the seven autofocus marks in the viewfinder) and compute the ideal shutter speed and aperture necessary to render all in focus.
**WARNING** If you buy the Rebel Ti kit at a warehouse (Costco or Sam's), check the lens -- it probably has the designation "III" on the front. The one from Amazon (and camera stores) has a "II" on the lens ring -- according to the Canon EOS website, the II has more elements and better specs than the III. If you can find a Rebel Ti kit with a lens marked "USM", that one is better still -- but the kit price will be ...more (and I doubt that the optical quality difference is even noticeable).

Canon has once again raised the bar in the world of 35mm SLRs with its EOS Rebel Ti. Canon claims the Rebel Ti has the fastest autofocus (AF) in its class, which should increase accuracy and precision for shooting at a real-life pace. A built-in flash pops up easily for shooting in low-light situations, and its extended arm reduces red-eye effect. The included EF 28-90mm f4-f5.6 standard zoom lens is an ideal all-around lens for wide angle to medium telephoto photography.
Fast, accurate, and flexible, Rebel Ti's three autofocus systems (the camera chooses the best one automatically) free you to concentrate on your composition and to just have fun. Seven focusing points cover an area wider than any other camera in its class, letting you place your subject off-center or even focus on the area covered by multiple focus points.
The glare-free laser matte viewfinder displays seven wide-area focusing points, which are clearly superimposed to guide composition. There's also a dioptric adjustment so that prescription glasses can be removed for up-close comfort. The extralarge LCD panel is illuminated for clear viewing whatever the lighting conditions.
You can rely on Rebel Ti's automatic exposure system for professional results, but the camera's special exposure controls give you lots of room for experimentation. With the camera's multiple exposure control, you can place up to nine images in a single frame for impressive surrealistic compositions.
Shooting feels natural because the shutter button, AF point selector, main dial, command dial, and even the LCD panel's buttons are all within reach for one-handed operation. The command dial has seven preset image controls for work in various common shooting situations.
The lens mount is solid stainless steel to handle Canon's full line of world-renowned lenses. A built-in, automatic pop-up flash eliminates guesswork. It recycles for action quickly, and with a red-eye reduction lamp built right in, images are natural and flattering.

PNY Optima 4GB SDHC Class 4 Flash Memory Card P-SDHC4G4-EF Review

PNY Optima 4GB SDHC Class 4 Flash Memory Card P-SDHC4G4-EF
Average Reviews:

I have a love/hate relationship with PNY. I've always been enamored with their prices, going back to the days of the GeForce4600 Graphics cards (they were one of the first vendors on the shelves). But they must cut some corners as far as QA is concerned. The plastic housing on all three of these 8GB cards have issues when inserting/ejecting from my Canon HF10, PS3 and Wii. The size of the card is slightly larger than the receptacle. I have the same problem with a Transcend SDHC 16GB card. Odds are, both PNY and Transcend purchase from the same OEM.
I have an 8GB SDHC card from SanDisk. I've never had physical size issues with that card.
I have no complaints as far as speed is concerned. Even though the card is branded as a Class 4 card, the HF10 rates it as a Class 6 and sustained transfer rates are in the 12 - 15MB/s range.
I can't speak to reliability. So far, I haven't had any issues with data retention, but then, I don't use these for long term storage. Nor would I ever recommend anyone use this class of flash for **any** long term storage purposes. That's what tape, CDR and DVDR are for.

Panasonic LUMIX DMC-ZS6 12.1 MP DIGITAL CAMERA BLACK - 3.0 " TFT Screen LCD Display Review

Panasonic LUMIX DMC-ZS6 12.1 MP DIGITAL CAMERA BLACK - 3.0  TFT Screen LCD Display
Average Reviews:

Panasonic makes the best compact superzoom cameras! Here's why. I was a professional photographer for over twenty years and recently sold all my professional film cameras (35mm, 21/4"x 23/4" and 4" x 5"). I've been searching for a compact superzoom camera that I can keep with me at all times to catch those once-in-a-lifetime shots without the expense or weight of a Digital Single Lens Reflex (DSLR) camera. Keep in mind that a compact superzoom has a smaller imaging sensor and will never truly compete with a high quality DSLR but if you want the best camera available in the compact point-and-shoot category then Panasonic DMC-Z series of cameras wins hands down. I've conducted an exhaustive search of camera review sites and have found Panasonic to consistently meet my standards of excellence. You don't have to take my words for it, you can check out my claims for yourself at the digitalcamerareview and dpreview web sites.
OPTICS:
The heart of any camera is the lens. Nothing else in photography counts without good optics. Panasonic uses Leica DC Vario-Elmar lenses in many of their cameras. Amongst professional photographers Leica has a reputation for quality akin to Rolls Royce. Leica appears to have maintained their reputation in Panasonic cameras by avoiding significant optical flaws. Most superzoom camera optics suffer from multiple flaws. Two optical flaws that I find completely unacceptable are chromatic aberration and uneven or soft focus.
You'll see chromatic aberration as a color fringe (red on one edge and blue or green on the opposite edge) along the edge of an object. It's often most visible near the corner of the image and along the edges of high contrast subjects like a dark car in front of a bright building. Sometimes chromatic aberration is so bad that it can be see in the center of a 4" x 6" photo but it's most often only visible when enlarged to full screen on a 17" or larger monitor. In my opinion, when it comes to chromatic aberration, Panasonic consistently out performs all competitors including Nikon, Canon, Olympus and Sony. I strongly suggest you see this for yourself by looking at web reviews that have full resolution images. Click on the full resolution image, zoom in and scroll from corner to corner and you'll see what I mean.
The second major optical concern is focus. Some camera lenses are sharp in the center of the photo but go slightly out of focus towards the edge of the photo. This usually isn't a problem if you are only going to use your multi-hundred dollar camera to make 4" x 6" prints but soft focus can be a huge disappointment when making larger prints or viewing the photo as a full screen image. The Leica lenses on the Panasonic cameras appear to excel in the category of sharp focus. Again, I suggest you see for yourself by zooming in on full resolution images available from some web review sites.
Other optical concerns include barrel and pincushion, which describe how vertical and horizontal lines can be curved in the photograph even though they were straight in real life. Some barreling or pincushioning is inherent to every zoom and are usually only noticeable at the widest angle or strongest telephoto settings. This type of distortion can be so severe that it distracts the viewer from appreciating the subject of the photograph. Leica does a superb job of minimizing barreling and pincushioning to the point that I find this type of distortion within acceptable limits.
My final comment on the Panasonic DMC-Z series optics is that the wide-angle setting on the zoom lens is equivalent to a 25mm lens on a 35mm camera. In my experience, the wide-angle lens is the most important feature of a zoom lens. You can always crop an image to get the equivalent effect of a stronger telephoto (of course you'll lose some resolution) but there is no similar way to compensate for not having a wide enough lens. Sure you can paste images together using a panoramic mode but you wind up with a long narrow picture that's difficult to put in a frame. Plus, except for the latest top-of-the-line Sony, you can't paste a large group photo together because people will move between shots.
SENSOR:
If the heart of a digital camera is the lens then the soul is the imaging chip and the camera's internal image processing software. Panasonic excels in this area too. Again, I strongly suggest you see for yourself by zooming in on full resolution images available from some web review sites. Every digital camera has software that is designed to minimize the noise introduced into the image by the sensor. If noise reduction is too strong then details are lost and objects start to look like cartoon drawings. If noise reduction is too weak then smooth areas like blue sky or concrete look unnatural because they're covered with dots. Panasonic has managed to achieve a pleasing balance in this category.
CONCLUSION:
Finally, I'd like to mention that, for the most part, I don't care about what photo editing or cataloging software comes with a camera. There's plenty of great software available from third party vendors and if the camera is not capable of producing a quality image then the accompanying software is absolutely useless to me.
So the bottom line is that the Panasonic DMC-Z series has the best combination of lens & sensor/built-in image processing software of any of the point-and-shoot cameras and is the most capable of producing an image that can stand up to being enlarged. Additionally, considering Costco has the Panasonic on sale this month along with their great return policy, I consider Panasonic a great buy.

Incorporating Panasonic's advanced optical technologies, this lens system is comprised of 10 elements in 8 groups, with 2 ED and 2 aspherical lenses / 3 aspherical surfaces. This lens system enables a remarkable 25 to 300mm range of focal length in a compact body.The 25mm ultra wide-angle lens has about twice the shooting area as a standard 35mm lens. This enhances shooting situations when you're photographing a group of people at a party or shooting a large structure or sweeping landscape while traveling.16x Intelligent Zoom/23.4x Extra Optical ZoomThanks to the newly designed Intelligent Resolution technology extends the zoom ratio by 1.3x while maintaining the picture quality even with digital zoom. This means the 12x optical can virtually extend to 16x equivalent. Furthermore, the Extra Optical Zoom function extends zoom power to 23.4x by using the center part of the large CCD to bring subjects even closer.Sonic Speed AFThe Sonic Speed AF system in the DMC-ZS6 includes numerous re-engineering enhancements, including a higher-speed actuator, optimized algorithms and parallel software processing. The result is fast and accurate AF performance. You can quickly get moving subjects in focus, such as when you're shooting sports scenes.

I purchased a digital camerea on ebay and decided to by this warranty on a whim. I am so glad I did. My camerea broke several months later leaving me pretty upset. I started my online claim the same day, which was so easy. They followed up with ideas on how to fix my camerea and a phone number to call if those ideas did not work. Of course my camerea was unrepairable. I sent it in and received a full refund within days. I could not be happier with my warranty. I will definetly buy this warranty to cover my new digital camerea.

My camera fell down after a couple of months use and it's barrel broke. Thankfully I had bought SqaureTrade accidental drop warranty. I filed a claim and they approved my claim promptly. I am very happy with them and always going to buy their warranty with Accidental drop for electronics. If I would have bought a regular warranty, I could not claim against the damage .

Simply put, there are more affordable options that provide more than adequate if not equal optics for the money. But if you swap filters often enough you'll probably find that B+W's filters have less issues with flex and, more importantly, soft (i.e., easily damaged) threads like those sold by Tiffen and Hoya that I've experienced in the past. Cross-threading a filter is NOT my idea of providing nice treatment to any of those expensive lenses of mine, and having done that once or twice in my lifetime I've sworn that I will always do my best to get the best-made filters available to protect and use on MY glass, even if it costs a bit more. Any filter can be damaged, but I've had great experiences with B+W products and until they prove themselves otherwise unworthy, will continue to use them again and again.

I just bought a new Canon camera and Amazon was shipping this card free with the camera so I naturally got it. Not really too much to say about it other than it works and gives me a little extra memory. The camera produced RAW as well as JPEG pictures so it needs a lot of memory so I'm glad to have this as a reserve. I have been buying brand name memory cards as I have read that bad chips are sent to the real cheap/giveaway manufacturers and this is at least rated a class 6 and I have heard of Kingston.
