Hi gents and lads,
I just got a lot of takumars with this fisheye conversion:

http://dpanswers.com/content/rev_kenko_wa16.php

I havent got time to take photos of it, so i did a quick search. The url above is exactly what i have. But with a generic leather case. There is no name on it, and original instruction/ user guide, in japanese and english.

After a search on ebay, i found one hit
http://www.ebay.com/itm/Kenko-Fish-Eye-Conversion-Lens-case-and-instruction-manual-180-/230730492181?pt=Camera_Lenses&hash=item35b89be915#ht_500wt_922

The case looks as mine.

The first url above is an interesting intro.

I bought one of those a couple years ago, at an actual camera shop, for too much money. I first put it on a SMC-A40-80 on my APS-C camera (K20D) and got a full-circle fisheye at ~40mm and a frame filling image from ~60mm onwards. I've since tried it on various other zooms in that range. I look forward to trying it on something like a 35-90 because the frame-filling projections get interesting at longer focal lengths.

But I've never been really happy with it. Its internal diaphragm needs to be stopped WAY down for any edge sharpness, which is never very good, at leas not on mine. I more recently bought an eBay bargain Precision Design Super AF Fisheye adapter (0.25x, 58mm thread) for US$20 shipped. I mount it on my DA18-55 or DA18-250 and get full-circle fisheye at ~18mm. More aberrations than the Kenko, but better edge detail.

Spiratone also offered the exact same adapter. There was one that just sold on eBay for $69.
