Excerpt: The inexpensive pricetag allows most shooters to enjoy the telephoto experience. Its not the sharpest, but it does get you closer to your subject to make for some fun imagery. A little work in post and you'll have a usable image.
Summary: Just purchased this lens to go with my Canon T3 camera. What little I've been able to use it, I've been very pleased with the results. Got good pictures with it so far and I expect it to continue producing just as well.

Summary: Have been looking for telephoto lens for a while and really could not afford the prices I was seeing. This is a great product as long as you use a mono or tripod. I use it for shooting wildlife that is hard to get close to. The price was right up my ally and very easy to mount to my Cannon Eos T3i.
Summary: I wanted to buy a cheap lens to experiment with high focal range telephoto photography. Mirror lenses inherently have lower sharpness due to their optics but they are much cheaper and lighter than their telephoto lens counterparts. This is a very basic lens so using a tripod is a must to obtain decent photos due to the fixed 6.3 f stop and lack of optical stabilization.
Summary: Yes its a 500 mm lens. It blows things up well. But color saturation and resolution sucks. Tried to take pic of the moon with it... yeah no it just never happened. Want detail in the pic... no not happening. The only good thing about this lens was that it only cost $160. Great little toy. I wish some people could do more with mirror technology to get better quality pictures.
