Great Hobbiest Lens
“I am very pleased with this lens… it is better than I expected for the money I spent… it is not for action… you have to be pretty good at manual focus… Depth Of Field is very shallow… I have taken lots of pictures of birds on over cast days and they have come out really clear… Havent had a sunny day yet but I’m sure it will improve the already good quality of the pictures… if you are looking for an inexpensive tele lens to have fun with, this is the lens for you… would definitely buy again if had to do all over again.” – by T.

Good lens at a great price
“I have had this lens for a couple of days now and I like it a lot. Very smooth operation and build quality at a great price. If you use this in low light conditions you will need a tripod. The lens has no auto-focus or image stabilization, of course at this price I can’t image anyone would expect it to. On a sunny day with a quick exposer you can ditch the tripod if you are quick at adjusting your focus. The extremely shallow depth of field can make focusing tricky with out practice though. All in all a great lens for the price.” – by Naz Drala

Opteka 500mm f/6.3 Specifications
The Opteka mirror lens is incredibly compact and lightweight. Using an advanced reflex design, this is a mirror lens that is ideally suited for wildlife and sports photography. It has a fixed aperture of f6.3. Opteka mirror lenses incorporates advanced computer designed optics and the latest in multi-coating techniques. The process of multi-coating assures virtually flare free photographs even under adverse lighting conditions resulting in crisp high contrast pictures with full color fidelity.
When combined with the T-mount to fit your camera system, this mirror lens mounts to camera and works on both “full frame” cameras as well as the “APS-C” style digital SLR cameras. T-Mounts are available for all the digital SLR systems, as well as for C-mount systems. However, in every case the fixed f/6.3 aperture is not communicated to the camera body. As such, you can use the lens in “M” manual exposure mode or “A” aperture-priority mode only.
This lens has a broad diameter and stocky build, making it a bit easier to handle than a normal refractor lens. It also has a much different rendering of out of focus areas than a normal lens; highlights will be doughnut-shaped rings with more saturation and contrast on the edge of the ring than on the center.
