Well, I've been trying to ask around and look around for some WA converters too for my Uzi.
I'm not sure why, but been asking at dpreview but not much feedback, somehow there's an obsession with adding more zoom instead. :dunno:
Well, so far, in singapore, there's the Vitacon 0.5x WA converter, AP and 3:16 stocks them i think, but i've experience viginetting with a 58mm vitacon, and the image is slightly blurred at the edges. I'm trying to find out if the blurring is a general occurance for WA converters or it's due to Vitacon's lens quality.
I checked with Cathay and they have a 0.6x Sony WA ocnverter, one low quality for about 70 and the a high quality for 200 if i'm not wrong. Didn't have time to request to check the lens, but i think the cheaper one might be plastic, coz it was very light.
If you do find reasonable WA converter, pls PM me or share on the forum, I'm looking around for one too. Thanks
