Originally posted by Just1MoreDave I have read that 67mm filters fit over the mini-hood. (I use this trick for my Sigma fisheye since it has no cap.) That might work better. The Zenitar doesn't focus very closely by itself, and that's one thing I prefer about my Sigma.
A 67 filter fits pretty loosely over my Zenitar's hoodlet. I just tried it. Let's see, what do I have in 67... ah, a Spectral Star filter! Just the thing for those romantic, seizure-inducing moods. Anyway, the filter has about 2mm of play, so I have to hand-hold it. I suppose gaffer's tape would fix that.
Originally posted by amityak thanks for sharing man. these photos have a very neat effect, even though really slight, as you say its not really a fisheye, it's just slightly bending all horizontal lines ... well, ill keep on considering getting this russian piece of glass (:
I'll go out soon to shoot some comparison shots of Zenitar vs DA 10-17 fisheye. The DA is a better lens, but it also costs much more. The Zenitar is better than any of the cheap so-called fisheye adapters, better than anything cheaper than the DA -- all these fill frames but don't produce 180 degree full-circle fisheye images.
If you're interested in full-circle fisheyes, the best lenses are VERY expensive. And the cheap adapter suck. But there are mid-point alternatives -- Spiratone and Kenko 180 adapters (also sold as various other brands). These are big chunks of glass that, when put on the right lens, DO produce a full circle. On your K10, that would be a 35-37mm prime, or even the kit lens. I have a Kenko 180 which cost me US$80 in a camera shop but I saw one on eBay yesterday for US$50. Read more about them here:

There's another common fishy ultrawide, a 12mm f/8 sold under various names -- mine is labeled
Vemar Fish-Eye. It's slow and tricky, comes on a T2 mount, doesn't produce a full circle on APS-C but it's MUCH fishier than the Zenitar -- and mine never works right. Search for
12MM for all the dirt. Have fun.
