What kind of quality do you get with those "converters"?

flockofbirds · 11-25-2009, 12:51 AM

I want to expiriment around with a fisheye, but I dont want to drop a bunch of money on it. How nice are those 60 dollar "converters" i see on amazon and such? Anyone have any experience with them?

Save that $60 toward a real fisheye lens. If you have to spend $60, send it to me. At least you won't have to kick yourself.

What he said...

You get the novelty aspect, but the optical quality just isn't there. There are a couple of shots from these lenses posted on the "Fisheye Fever" thread, though you are going to have to seek them out.

There is a 12mm fish-eye lens that shows up on ebay. Sells for about $140. The name will vary, Spiratone, Sigma, Accura, etc. It is a T-mount and will fit most any slr with the right T-mount. It is fixed focus and has an adjustable internal disk with 3 different holes for f-stops of f8.0, f11, f16. If you don't have the money for a 10-17mm, you can try out one of these.

Those things basically add distortion to the lens.

I like using my 6.5mm Opteka fisheye on my K-7.

I have a .45X wide angle adapor, and although it works great on my Kodak P&S it is somewhat disappointing when I put it on myu adaptall II 24mm.

It is only sharp in the center not at the edge.

My conclusion is that these things are really only for P&S lenses not those on an DSLR
