Opteka 500mm / 1000mm f/6.3 Telephoto Mirror Lens for Canon EOS 1D, 5D, 6D, 7D, 10D, 20D, 30D, 40D, 50D, 60D, Rebel XT, XTi, XS, XSi, T1i, T2i, T3, T3i and T4i Digital SLR Cameras


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.

Great Lens !!
I just got this lens last week, for the money, or even at twice the cost you could not find a better 500mm lens (1000MM W/2x adapter). Very good quality mechanically. I'm using it on a Canon EOS T3, and the photos are very sharp with good color and almost zero chromatic aberration, even when using the 2x adapter at a 1000 MM. It only works with manual focus and has a fixed aperture, so you must manually set the shutter speed, or let the camera set it automatically, for proper exposure. Getting subjects into focus takes a little practice, but when you get the hang of it, it's not that difficult. It's a good idea to use a tripod when setup for 1000 MM.


Great for the Money
Use a tripod! This is a no-frills lens that requires some time to familiarize yourself with it. That said, I've got some great photos with it.


Manual focus is the only drawback
I bought this lens to put on my backup camera (dslr). I now sit on the back porch and can take pics of the wildlife from a bench. I put a monopod on the camera because it is cumbersome but with a 2X converter it is great for long shots.

Bower SLY500PC High-Power 500mm f/8 Telephoto Lens for Canon


The high-power 500mm telephoto lens for Canon EOS is a manual fixed focus multi-coated T-mount lens that yields images with impressive peak contrast and well-controlled flare. It has a minimum focus distance of 33 feet and a 5° angle of view. It has a 67mm thread and includes a tripod mount, black lens pouch and a T-mount adapter for Canon SLR cameras. For best results, use with monopod, tripod or chest supports to alleviate shake.

For what it's worth
I picked one of these up for shooting the moon, not for any other reason. Here's some useful information on the lens. First of all it is incredibly light. My Nikon 70-300 weighs more than this lens does. Second of all, the T Mount is simple to attach, just turn it backwards on the lens and you'll feel the threads line up, then tighten it up. Most important this will work with ALL Nikon F mount cameras. However, you need to understand that this is not a CPU lens, it sends no info to the camera body. Meaning you must use it in manual mode. I set my lens to f/8 and used the manual setting on the camera to set the shutter speed. If you follow the camera meter, the shots are going to be way over exposed. So use an exposure meter, or a chart. I shot a half moon at f/8 for 1/1000 of a second. ISO 400. I'm using this on a D2H so I attached the camera to a tripod rather than the lens. Rather have a cheap lens slip than my camera. The lens is long so any vibration is going to be...


patience and a tripod
So I was skeptic about this but I decided to gamble and so far I feel like a winner! If you only shoot in Auto mode then don't buy this lens. "M" is where you got to be. There is no communication from the lens on the aperture and no light meter reading. Basically it's up to you. Just play with your ISO and shutter speed. I kept previewing shots on my LCD display and adjusted from there. Yes, it's possible to get some quality shots. You need a tripod but I shot from my car door. I will be uploading three bird pics I took this morning if I can.


Works great on my EOS T3
I bought this lens for the price point and knowing that I would not be using a 500mm full time and I was not spending $10,000-$16,000 for the Canon model. I have been a photographer for years, formerly doing professional portraits and now as mostly a hobby so I have no qualms about using a manual lens.

I tested it this last weekend after it arrived Friday on wildlife in my backyard and I have gotten some awesome photos with it! Squirrels, birds, chipmunks, etc all sharp and crystal clear. If you are not experienced with manual lenses this might not be for you but if like me you are or willing to take the time to learn this lens is well worth the money!!
