Thanks!
Hi Amama:
I so much miss my days shooting with this lens. When I was active with it, I had good knowledge of all the major, as well as subtle differences between the 2 versions, If you carefully sift through this thread, you'll find discussion on the differences--in depth at times even. Off the top of my memory, so please do not quote me here, I'll try and quickly review some differences, aside from the obvious ones: price--speed--fixed aperture
3.5 version reported to handle flare a little better, though the 4-5.6 is no slouch for UWA. 3.5 versions has an extra A-Blade, given it an odd total, which makes for nice sun flares--distinct points. Reports (I believe SLR, for example) say 4-5.6 is sharper at the long end. Also, @ 10mm (according to Photozone) I believe the 4-5.6 version is better in the extreme borders while the lenses are close elsewhere @ 10mm. 3.5 version reportedly a little better with vignetting and with distortions. Feel free to Google subject and report back here anything you can add tot he discussion. Thanks and Happy Shooting!
