I am very satisfied with this Hoodman loupe. I first purchased one for my Nikon D40 when I had difficulty viewing images and the histogram on my LCD screen. Now I also have a Nikon D7000 and the loupe works great when lighting conditions prevent me from viewing the LCD screen. The Hoodman loupe is very durable, however, once it got caught on the front rail of a whale-watch boat. The band on the neck of the loupe came off, but didn't break. I was able to re-attach it by slightly twisting the loupe from the hood---good as new! It comes without a case, so I store it in a baggie when not in use. Several people have borrowed it to look at their camera LCD screens when I have been at photo workshops. I recommend this for anyone that wants an optimal image on their LCD screen for those times when they can't clearly see the images or histogram.
