Summary: Not that it's not good...but right off the bat I noticed that's it's totally manual...I wanted to do wildlife action shots...I have no time to manually set this thing...shot would be long gone...Sorry...my two.

Summary: You do get what you pay for. It does work well. I only wish I had read a little better.. You can not zoom in and out on this lens.. it is set to 500mm. I have taken several photos of base ball games and gotten some pretty good shots from the opposite side of the field (outside the fence) facing the batter. at 500mm got pretty clear shots. Upside, if you have decent light from mild cloudy day to bright sunny day this lens works great. but light at 6pm.. not so well..
Summary: This lens performs amazingly well for a mirror lens. Mirror lens by their very nature are not quite as crisp as refraction lenses so I was pleasantly suprised at the quality of the shots I got using this lens.
Summary: This lens is a good affordable alternative to the expensive telephoto lens that can run several hundred dollars. This lens performs exceedingly well when used with a tripod or other support. It takes a bit of practice to get the focusing down but it is well worth the effort. Opteka has always provided nice quality equipment at very reasonable prices.
Summary: I love the way this lens performs and I've had trouble with mirror lenses. The Opteka 500mm captures a perfectly crisp image and Im happy with the quality of shots the this lesser known brand of products produces. I would say that for a sub $100 Mirror lens you can't go wrong with this.
Summary: I just wanted to throw in 2 cents from experience. I have a similar long T-mount lens from back in film days. You have to make allowances if you buy one. For perspective look at the prices of similar branded, auto focus, stabilized, premium glass lenses. This is not one of them. It does not have stellar optics, but it's good enough. It in no way communicates with modern cameras. It's old, old school manual. Best to have a handheld meter and learn to use it.
