Sharp, but rather high vignetting and CAs.
Wow... Markus you are unstoppable these days... The long time awaiting WA FX tests are finally here and now we the readers are stuck in them... (you see I don't stop complaining <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/tongue.gif' class='bbc_emoticon' alt='
' />). Anyway, thanks a lot for the effort.
Based on the results, I can tell that I feel relieved about my recently bought 20mm. Yes it has a vignetting problem as reported, but it is sharp in the center and
borders between F/2.8 and F/5.6 compared to these two.
