I love this device on my D800. On my old D200 I used a focusing screen but I don't need one with the D800 because of the larger viewfinder. However, my eyesight is a bit blurred and I often use manual focus lenses & wide aperatures so I bought the eyepiece magnifier to help out. It magnifies the viewfinder by 20%, making it even easier to check focus visually. It does eliminate some of the outer black edges from the viewfinder but nothing is cropped from the image itself. I can still see the green focusing aid dot and the other viewfinder information just fine. The top image corners are a bit vignetted and the very tip is cut off, but it is very minor and but nothing that bothers me. Before, I was using the 2nd last click on the camera's diopter adjustment. Now I can dial it back 2 clicks so I have more room if my vision degrades further. I also tried it wearing glasses, which I don't usually do. The frame edges are clipped a bit wearing glasses, so you may not like it if you must wear glasses using the camera. For installation, the old eypiece screws out on its threads and you replace it with this one. It takes far less than a minute and is very easy for anyone to do.

This is a great product. It helps me with my objective of manual focus. It's worth every penny invested.

Great quality, but even though I've heard that it does not has a good fit to the camera I have bought it. Excellent, but after two weeks in the field it has dropped and is lost somewhere in my birding forest. Maybe for a study user It will last. Just rub it in your clothes and it will detach and fall from your camera :-(
