Opteka 800mm f/8 User Reviews

Verry nice pics shot with this lens, clear and high def
“I bought this lens for wildlife shots and found it good for surf shots. I used it for high def shots of the moon and I am very pleased with the quality of the lens! “ – by R. Terwilliger

Very Nice Indeed
“I had an old Nikkor 500mm mirror lens which I gave to my nephew because it sucked so bad. This Opteka lens has a lot longer focal length, is nice, and is reasonably priced. It seems just a bit better than the Nikon, and much less expensive of course. Manual focusing is very touchy – on both lenses. Just a law of physics. Of course you almost have to use a good stable tripod too. I recommend this Opteka lens highly. I use it on my Nikon D300s and the D80. “ – by Paul Garland

Nice lens but only works on Manual
“Pictures seem good from a first try with the new lens. As with the other reviews, focus is tough to get right but worth it when you get it right. I have a D40X and as a heads-up to others the camera will give the message “no lens attached” if you use any mode other than Manual so if that’s okay then go ahead and get one. “ – by M. Knight

Diamond in the rough
“Synching with a flash was a revelation. The first time I used a flash and saw the results I began to realize how clean and sharp an image this lens was capable of. Of course there are very few situations where you can use a flash with an effective focal length of 1200 mm and closest focus over 11 feet…but it is an useful exercise to learn the abilities of the lens, or if you like to extremely flatten your portrait or still life visual space…” – by Jeffrey L. Beddow

extreme telephoto
“I bought this lens to do some nature photograpy and it did exactly what it was suppose to do. It required high shutter speed or tripod stabelization for sharpness and with its very narrow depth of field focusing was critical. But it did exactly what I needed producing great photographs. “ – by Buck
