Customer Reviews

First know this: This lens is NOT specifically engineered for any particular camera. Mine was sold with an adapter for K-Mount Pentax, but that is the only difference you're going to get.
Reviews for this particular Opteka lens are nearly non-existant, so I figured I'd write one up.
I got mine new online for only $84.95, and I'm glad I didn't pay more. This thing isn't by any means what is described in the product description. It's basically what you'd imagine getting for $100 new. It can't be good, can it?
Well, it depends on what else you've used. Having used much higher quality lenses, it's hard to go backward. I bought this with the ambition of doing a little astrophotography (moon). For this purpose, I guess I can deal with it. And, it only was about $100.
My qualms reside in the quality conrol issues. You can't just rotate the focus to infinity with this if you want infinity, because the markings are off. The aperture ring on my copy seems to be broken: the part that is "snappy" doesn't change the aperture, this loose, unmarked second ring below it does. The whole thing is a little loose where the supplied adapter connects to the camera body. It just feels cheap. Also, it says "Made in Korea" on the lens although it is supposed to be manufactured in Japan.
The T-Mount adapter supplied with mine makes the lens screw on so that the focusing and aperture numbers face the right side of the camera, instead of being in plain sight on top.
So, if you want sharp, crisp images, this isn't your lens. If you're just looking for something to experiment with, this is a pretty cheap way to do it.

this a great telephoto for beginner photographers, especially the price.
it is not the highest quality lens on the market, but I have gotten some good shots from it. As with any long lens, you really need to use a tripod for this one. Don't let the f-stop dials fool you, like it did on a previous review i read, there are two f-stop dials. the one furthest from the camera is a dial that changes the f-stop in stops (8, 11, 16, 22, ; 32). The second dial closest to the camera (O <--- C which means "open or closed") gives you everything in between, to fine tune your f-setting. pretty versatile for such a inexpensive lens. Anyone that complains about this lens is probably a professional who is used to using $3,000 lenses ; therefore has the right. But if your an amateur or a even pro on a budget, go ahead ; get this lens. For under a hundred bucks, why not?
