I'm about to buy a WA lens and I'm in limbo between the Tokina 17 ATX-Pro and the Canon 20 2.8. I'm not that fussed about ultimate wideness. I'm not a great fan of the wierd perspective you get with ultra-wides. So the 3mm difference is not an issue. I'll probably never use it wide-open either, so the 2.8/3.5 doesn't matter. What I want is image quality and build quality (in that order). You don't hear much about the 20mm, is that because it's one of Canon's poorer lenses ? I hear alot about the Tokina (mainly from drisley
) so should i just get the 17mm or has anyone had any experience with the 20mm ?
Cheers
Gary
Ok drisley, let rip !!!
