This is just a gas. It is very useful, and what a joy to use. I can take photos with the camera in any position and see the actual image as seen in the LCD screen in real-time. Over my head, on on the floor, or even around a corner if needed. This thing is terrific. I was going to buy the conventional 90 degree angle finder, but wanted to be able to take photos over my head (holding the camera above a crowd if needed) and this allows that, and more. Great item, a bit pricey, but it is a gadget after all. I love it, and the flexibility it provides for my photography. It will be a terrific augment for creativity.

I was optimistic about this unit but I'm happy to say that it worked like a charm. Unit went on tight and right. No issues with it falling of or not being able to get the unit on my 50D. I haven't tried to remove it and don't plan on it. I'm 6'2" and like looking down into the camera so I'm leaving the thing mounted. I feel like you can take more creative shots because you can rotate the eyepiece 360 degrees! Me Gusta! Hope this helps you out on your next purchase. Good luck.

Opteka Professional 1X-2.5X Right Angle Viewfinder for Canon EOS, Nikon, Olympus, Sony, & Pentax Digital SLR Cameras Review

Opteka Professional 1X-2.5X Right Angle Viewfinder for Canon EOS, Nikon, Olympus, Sony, and Pentax Digital SLR Cameras
Average Reviews:

If possible, I would RATE THIS ITEM 2.75 STARS
I have had the Opteka Professional 1X-2X Right Angle Viewfinder for several months and have used the device in a variety of situations and lenses, mounted to a Pentax K-20D camera.
For starters, to classify this product as having been designed and built to a professional standard and grade is a true stretch of the imagination. In terms of optical quality, I have seen better optics in a $20 pair of binoculars.
First, the coupling optics in the Opteka finder are not large enough to see the entire K-20D viewfinder frame (see photo), a very typical DSLR. Because of this, there is a lot of edge clipping of the camera's viewfinder field of view. This makes the corners of the frame dark from vignetting and hard to see objects in those areas of the frame during low lighting conditions to get proper subject composition.
Second, the quality of the Opteka view finder optical design and the lenses used could be described as sub marginal at best. Only the central area or about 12-15 percent of the K-20D viewfinder frame (see photo) is suitable for obtaining critical focus when the Opteka right angle viewfinder is mounted to the camera. Spherical aberration, coma, field distortion and off axis chromatic aberration are very bad. With the Opteka finder integrated, it is hard to read the digital displays in the camera's viewfinder.
Because the aberrations in the right angle finder's optical system are too uncontrolled, the finder becomes less functional as lighting conditions drop. The high level of optical aberrations also has a negative impact on image contrast in the finder. Since contrast in the finder is low, it is difficult for a typical person in their 40's and older to judge best focus at dusk as not enough focused light and contrast is visable to the older person. A side effect of maximum pupil size as a function of a person's increasing age.
Third, the molded plastic Pentax adapter piece (see photo) for the Opteka right angle finder slips off much too easily from the view finder, leaving the adapter on the camera. Too little manufacturing tolerance control is built into the part, for that reason, the finder does not stay in place when pointed downwards or mounted upside down such as when the camera is piggybacked on to a telescope mount, or rotated about the optical axis.
Forth, the surface finish on the Opteka finder exterior is not very good. Note the excess paint build up (see photo) and blistering on the diagonal housing. This, although minor, is a reflection of the generally low standards at Opteka.
Last, the bottom half of the Velcro base pad for the finder's case lid was not sewn on to the case properly (see photo). The stitching misses the lower part of the Velcro pad. Hence, the case cover could rip the Velcro base pad off, if not careful when opening the case. Note in the photo how the case lid tries to pull off the Velcro base pad.
In conclusion, Opteka seams to exhibit little quality control in their manufacturing process for this many issues to surface in a single product. The low quality of optics in this Opteka finder is easily superseded in quality by a pair of $20 dollar binoculars. The case and related camera adapter in their current form are essential add on items that offer very little value to the overall purchase. All things considered, with a purchase price of 49.95, the Opteka right angle finder, in my opinion, is overpriced.
Minus 1.00 for all of the optical aberrations.
Minus 0.50 for the clipping of the field edges.
Minus 0.25 for sloppy finder to camera adapter fitting.
Minus 0.25 for low quality finish.
Minus 0.25 for low quality construction of the finder case.
Additional note: The large recent (Winter 2009-10) increase in the list price of this item to the ridiculous and stratospheric price of 199.00, for the purpose of projecting to an unknowing customer the erroneous perception of receiving a "good deal" is unethical. Regardless of the motivation, raising an arbitrary value such as the list price for a marginal item that is all ready over valued does not make a purchase any more agreeable but simply laden's the sale with more deceit.

Seagull 1x-2x Right Angle Finder for Canon, Nikon, Pentax, Minolta, Fuji, Olympus and Leica SLR cameras Review

Seagull 1x-2x Right Angle Finder for Canon, Nikon, Pentax, Minolta, Fuji, Olympus and Leica SLR cameras
Average Reviews:

The quality of the Canon Right Angle Finder C is high but the fit was quite loose on my Canon XT and 50D. The metal portion of this finder with the prongs had slightly worn a tiny bit of the top edge of the glass LCD so I decided to look into the Seagull version. The fitting of the Seagull version is plastic so it should not damage glass at all. I also heard the fit was tighter, which I hoped would be safer after I accidentally popped my Canon one off the camera quite easily a few times.
I actually received the newer model of the Seagull that goes up to 2.5 in magnification (there is actually an even newer one providing 3x magnification). The adapters were supposed to be made from a better quality of nylon than the previous versions. Here's my findings:
1. Quality:
The Canon is definitely a higher quality item and it has a heavier feel. The Seagull is much lighter. They both are mainly plastic with a metal barrel that is rotated for focusing. Both the Canon and Seagull fit snugly into their included soft cases. The Seagull appears to be a little snugger fit and may take a bit more fiddling to get it into its case.
2. Fit:
This may vary depending on the camera but I will report on what my experience is with my Canon. The adapter labeled for my Canon 50D was actually too big. I had to use a smaller size (labeled for the Canon Rebel line) that fit too snugly. With the Canon finder, I did not require using an adapter but it attached too loosely to my camera, even though I tried to bend the springs in to make it fit more securely.
The Seagull's adapter had a tighter fit but it was so tight that it was not possible to remove the viewer together with the adapter still attached to it. The fit between the viewer and adapter was loose enough that swiveling the viewer misaligned it from the adapter much too easily. The tightness of the "clicks" inside the rotating mechanism meant that I had to firmly hold the base while I rotated the viewer in order to keep the whole unit properly in place on my camera. This was the same problem I had with the Canon viewer.
When removing the Seagull viewer, the unit itself came off easily and left the adapter attached to the camera tightly. The fit of the adapter was so snug that I had to use both thumbs under both corners to push it off the camera's eyepiece fitting (and hoping I don't pop it off into oblivion). However, since this adapter is plastic, it might wear down over use and become looser.
3. Operation:
The optics of the Seagull is as good as Canon's. Like the Canon viewer, ball bearings can be felt when swiveling the eyepiece to different angles.
There are also little "notches" that can felt that are set to specific angles for the finder. These are much looser in the Canon viewer and it was very easy to accidentally rotate the eyepiece from where you had it set. The Seagull's are much tighter and the force required to rotate the eyepiece actually causes the unit to misalign from the adapter attaching it to the camera. With both the Canon and Seagull viewers, you have to keep the right angle viewer in place with one hand while you rotate it with your other hand. This can be awkward especially for handheld photography.
The focusing systems are very similar between the Canon and the Seagull.
4. Value:
As mentioned at the beginning, the Canon right angle finder is a better quality piece but it also costs almost 3 times as much as the Seagull version. The Seagull finder works as well as Canon's and is a good deal in comparison.
Conclusion:
The Seagull right angle finder does what it is supposed to and would be especially trouble-free for photographers who often use tripods and do not remove the finder from their cameras as often as street and event photographers or move around as much. I was disappointed to discover that the problem of looseness was still there... but in a different form than my Canon finder. The adapter attached to my Canon cameras too tightly and was too loose where the adapter itself attaches to the Seagull finder. To shoot in a "normal" mode without the right angle finder, this meant that I had to first remove the Seagull finder itself and then use both thumbs to push off the adapter. This is a nuisance that varies depending on the individual.
This loose fit with both the Seagull and Canon right angle finders requires that one much be careful not to accidentally knock it off the camera. The Seagull finder is much more reasonably priced and the build seems to be of a good quality. It is a good alternative to the Canon version as it provides the same purpose of use. I gave this a 4 star rating because of the general loose fit onto the Canon camera. If the adapter and the fit between the finder and the adapter where both equally and adequately better fitting, it would have been perfect. Only time will tell if some of the tightness of the parts will loosen. I would have given it a 5 star rating if I only considered the price and quality.
Update: 01/26/2008
I have used this a few times now. It feels and operates exactly the same as my Canon right angle finder. This also feels more secure on my camera and would take a good bump to knock it off. The Canon version always feels as though it could slip off because of its heavier weight.
I have noticed that the Seagull finder's case is too tight of a fit. It takes some fiddling to get it back in when I am done with it. I might pick up a small camera case to replace the one it came with.
Update: 02/12/2009
I picked up a Crumpler gadget pouch which the viewer fits much more easily into. After using the Seagull viewer for a while, the fit onto my 50D has loosened a bit and it is easier to remove. I have noticed no difference in the way this works in comparison to my Canon right angle viewer. The Seagull version actually feels more secure on my camera since it is lighter and doesn't feel like it will fall off because of its weight.
For anyone who doesn't care about having the Canon logo on this accessory and would rather save some money on what essentially does the same thing, the Seagull right angle viewer is a great alternative. If I had a chance to decide all over, I would have purchased this instead of the pricey Canon one.
Update: 01/05/2010
It has been almost 2 years and one of the prongs on the plastic adapter broke off. Luckily, the Seagull finder still stays on fairly securely with the remaining prong but I have been unsuccessful finding out how to replace this broken part. I have tried contacting the original seller, the distributor and the manufacturer in China by email. It has been about 3 weeks and I have still not heard anything from any of them. I guess I will have to continue using this viewer with the broken adapter.
Update: 04/15/2010
The adapter loosened with use and eventually popped off without me noticing at a beach. Having contacted almost every seller of this viewer I came across, the ones who did reply were either unwilling or unable to sell me just the adapter that I needed. I decided to give in and purchase another entire Seagull Right Angle Viewer, even though I still have my Canon version. I had used it a lot over the two years that I had it so I suppose it was worth making the purchase again. It is just too bad that I could not just purchase the adapter so I could still use the one that I already had. Beware... getting any service or assistance after purchasing this is near impossible but the low cost sort of makes up for it.

This right angle viewer is made with the highest quality optics. It exceede my expectations. I shoot a lot of Kindergarten students and need a low angle of view. This piece is easily slipped on and allows downward viewing (with correct orientation of subjects) without sitting on the ground. I would recommend this viewfinder to anyone needing a quality right angle viewfinder. Mine is attached to a Nikon D200.
