Opteka 500mm f/8 Preset Telephoto User Reviews
I liked it
“I did sell my lens but I did not have problems with the picture quality at all. You have to really be careful though how you set all of the settings to get pictures really far away to come in clear. This is a professional lens, and it does take some knowledge to use. As far as cheap, I do not for one minute think that this lens is cheap. It is built very well. As far as not being able to take pictures in the dark like the other review said, my God you are shooting so far away you would have to have football stadium lights for a flash if you wanted to light up the place in the dark. I really liked the lens pretty good.” – by James R. Parks
Impressive for the price
“After adjusting the aperature of the camera for varying light conditions, this lens will produce very good pictures, when mounted on a stable tripod. The construction is excellent and impressive. The price of this lens, for what it will do, makes it a good purchase and will give some versatility and fun to picture taking, and as stated before, adjusting the camera for varible light conditions is necessary as the camera will have to be set to manual mode. Also, the vendor, 47th Street Photo, provides very good service. “ – by JCJ
