Hi to the forum, I'm new and found this forum thru a Rainer Viertlböck post. It's great to see the quality of info here.
I'm mostly a returning architectural/lifestle/garden photographer moving from film to digital. I started testing the D5 this past week with a 35mm F2 and was surprised to find so much fringing with chromatic aberration in high contrast areas of the image. I shoot in high contrast high flare situations a lot.
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. "
Does anyone know of a site or have some info on the Canon line of lenses and fringing? I noticed that the MTF curves for many of the regular EF lenses charted better then the L lenses at f8 and I usually shoot in the mid to high f stop range. But I haven't found comparative info on fringing.
How do the L lenses compare to the regular EF lenses on fringing at mid to higher apertures ? And how can I contact Chuck Westfall for their info to follow up on this?
To start my lens test ball rolling, I ordered the 20 f2.8, 24 f2.8, 28 f2.8, 35 f2.0 100 f2.8 macro and will keep them as backups if I think I need to get the L series lenses. I've held off on other lenses till I gather more info.
Any guidance will be greatly appreciated,
