mcoplus1.08x-1.60x Zoom Viewfinder Eyepiece Magnifier for SNY NEX E Mount/Canon Nikon Pentax Olympus Fuji Samsung Sigma Minoltaz DSLR Camera

Works exactly as described. More than happy with the product. Just wish it magnified a little bit more.Only Con is it stops the display screen from moving but I have found that I can take the magnifier off relatively easily (just unscrew it) if I want to unfold the screen. Did read a review saying it "falls off too easily." Certainly don't have that experience. My guess is that person is using the wrong VF attachment for their model of camera...Finding the right one out of the 6 provided was a little hit and miss, but after a couple of minutes of trial and error I found the right one for my Canon 80D.

I’m an amateur photographer with a Canon 5D Mark IV and a few manual focus prime lenses.I primarly bought this to make manual focusing easier. As a bonus, it also ensures your face has a little extra space from the back of the camera when looking through the viewfinder.The build quality of this seems pretty solid. The optics of this are not the best, but for such a small piece of glass it’s fine. There is some pincushioning at the corners, and you lose the ability to easily see the corners without literally shifting your head a bit and looking straight at the corners, but I expect issues like those from a magnifying eyepiece. Other than that I didn’t notice any glaring issues with the build.This came with zero instructions. It wasn’t terribly difficult to figure out, but it took some trial and error for me to get to the point where it is securely attached to my camera and I don’t really worry about it falling off.The basic steps:1. Remove your current viewfinder.2. Find the viewfinder attachment that matches your camera model and slide that piece onto your camera.3. Remove the lens caps from the optical part of the new viewfinder.4. Rotate the Lock/Open nut onto the viewfinder until it is flush. It doesn’t have to be super tight st this point.5. Screw the optical piece of the new viewfinder into the part that you slid onto your camera in step 2.6. Place your hand on the lock nut on the part labeled “lock” and turn it towards “open” until it is firmly in place. It may seem counter intuitive, but this should put pressure on the piece attached to your camera, locking it in place.7. Attach your preferred eyecup.8. Adjust your camera’s diopter.The last step is important. The diopter adjustment *will* need to be done any time you change magnification if you want accurate results.In practice, this eyepiece helps a lot with manual focus. I would still love to change out my focusing screen, but this is a cheap, non-invasive alternative.The main manual focus lens I use is a Carl Zeiss 85mm and has a very long and smooth focus throw. The changes in focus used to be less apparent, but with this eyepiece, using the largest magnification, I feel more confident to take fewer shots and know I have my scene in focus.For that reason, the diopter adjustment is really important.There are many ways to do this but the best way is probably to use an auto focus lens on a tripod, focus at a fixed target, and then turn manual focus off (so as not to accidentally change it). Then adjust your diopter until what you focused on with the lens looks sharp in the viewfinder.I was able to adjust mine on the fly with my manual focus lens without a tripod by taking a shot at my subject and viewing it through the LCD screen at 100%. If, by looking through the viewfinder, I thought it was sharp but the image recorded was not, I adjusted the diopter until what I saw in the viewfinder looked like what I was seeing in the image on the LCD screen.Then, I re-focused the lens, took another shot and repeated the process until the recorded image appeared sharp and I couldn’t tell a difference between the sharpness in the viewfinder and the recorded image.This product isn’t perfect, but it’s the best I’ve found for my 5D Mark IV. I might consider something like this with fixed magnification, but I prefer being able to adjust it for different scenarios even if it means having to adjust the diopter.

This would be great and worth five stars if it would stay on the camera. I have had to replace it twice in the past and now the last one I purchased two months ago in February, fell off somewhere and was lost. The manufacture needs to design a way that this will not easily fall off the camera. That would make me give it a five star rating. Right now, I can only give it a two star for poor design regarding attachment to the camera.UPDATE: I have to change my rating to 1 now since the eyepiece has clouded up internally. There appears to be liquid inside between the glass elements and I think it has leaked or something. Don't know how or why this happened but the eyepiece has become unusable. I have replaced it a few times because it had fallen off and was lost. Now it is simply unusable. I am not going to wadte any more money on this item.

This product really does make a difference in magnifying the pictures. The only that I noticed was if I have the rubber protector on it ,it makes the picture small. It is great for someone that needs to wear glasses or has trouble seeing clearly.

Does not fit Canon 60D. Yes, it does fit as the original eyepiece would, but you cannot open the flip out screen without partially removing the eyepiece EVERY TIME. I shoot almost always through the eyepiece, but you have to flip out the screen to view your pictures. So I guess you could leave your screen facing out, but I like to close it after shooting so it is protected.

I wear glasses which is a photography nightmare.. This item has helped my shots become more clear because I can actually see better through my viewfinder now. Its helped bring things into focus better. Especially if your farsighted or need to wear reading glasses. The cup is big enough to rest against the lens of my glasses and helps to reduce distracting light
