Anyone,
After searching out past posts on this forum, here is a partial quote by Asher on the subject.
"I stopped using the 50 1.4 for my digital work because of birefringence, purple blue lines between high contrast areas that bother me and Chuck Westfall of Canon USA says is a lens-sensor issue specific for each particular combination and there's nothing to change that.
As far as fringing goes, I looked up the 50 1.4 USM at
http://www.photozone.de/8Reviews/lenses/canon_50_14/index.htm
which charts this lens as one of the lowest fringing lenses around. However Asher seems to have hit the right combo. Asher, if you are out there, what body are you using? I'm teching out the D5 and wonder if anyone has had problems with this combo or perhaps with the 1Ds MkII.
There is a sample photo on the photozone site
http://www.photozone.de/8Reviews/lenses/canon_50_12/samples/IMG_2811-01.jpg
which shows some purple in the trees to blue sky.
Also, I know most people love the 50 1.2 L and it is great for low light etc photos, but photozone shows fringing to be large on their summery page at
http://www.photozone.de/8Reviews/lenses/canon_50_12/samples/IMG_2811-01.jpg
along with a photo which is probably optimized for showing the problem. However, their chart also shows this lens to have more then usual for a fixed focus lens. Is the going practice to just know to correct in software?
Perhaps high contrast tripod based shooters have gone to other adapted lenses for outdoor location or architectural work on the D5 or 1Ds MkII?
Thanks to users. I'm trying to stay in the Canon lens line before going to Zork type solution for fringing....... http://www.zoerk.com/pages/products.htm
