It does what it says.

It does just what the advertisement says ...no more no less. In bright light it performs well. It's more usefule for fun than as a daily work tool.

Not bad for the money

By

from Dunedin, Fl  -  Photo Enthusiast

I was looking for a long distance lens that would not cost me an arm and and a leg. This one fit the bill although I have not really used it very much as of yet.

GREAT lens for limited usage

By

from Chehalis, WA  -  Photo Enthusiast

This lens for the money is a worthwhile lens.I do not have a great need for 400-800 but for the money you cannot go wrong.As other evals stated, you need to shoot manual and your f/stop is fixed.You will need to use your shutter speed and ISO for light configuration.It takes good pictures but focus is not easy and takes some time to get used to. Shooting small away objects (birds and such) would be easier since it narrows the area of your focus or just long shots at infinite. If your subject is in focus the picture quality is between good and excellent. There is no tripod mount but the lens is light enough that the camera will mount on a tripod. Once in focus I use a wireless remote so no camera shake, it is that sensitive. If you shoot a lot of distance this may not be the lens for you, but you will easily spend 10-20x the amount. For occasional usage like me it is great.

Almost Returned It

By

from Saco, ME  -  Photo Enthusiast

I have a T-mount for my Telescope. When I want to spot rare wildlife or things that I know are going to be at a great distance (mostly wintering ducks in a few local bays) I lug this 25lb contraption out... Its not easy, but its 1250mm focal length has been great to document wildlife. I got this lens because 800mm and VERY Light. Its a compromise. You definitely need a tripod and I recommend using live-view to try to get a sharp focus. The issues is that like a microscope this needs a coarse and a fine focus. It is very difficult to get a clear shot that is in good focus.

problem with description

By

from Albany, CA  -  Semi-Professional

There's a problem with the sentence: "Aperture is fixed and the Kenco Vari-zoom lens should be used with cameras set to a shutter priority mode": with a fixed aperture, the camera should be on APERTURE priority AI (or manual...) mode.

I'm happy with this product

By

from Newport Or.  -  Hobbyist/Enthusiast

I have a Canon eos Rebel G, I used my new lense and got my pictures back. They were alittle fuzzy with a couple of pictures, but, I didn't use my tripod, I believe that's why they turned out that way. Next time I'll use my tripod and remote. The T-mount that came with it, the red dot is a little small and hard to see, so if you don't line it up right, it won't lock up properly, but over all, I'm pretty happy with it.
