Thx much. > >Ken Ken - I used to have a gallery up on pbase showing the CA and fringing from my Canon lenses when I was trying to find a solution, but the solution turned out to be an M8 so I took the photos down. Here are examples I found on Google: http://www.usa.canon.com/dlc/controller?act=GetArticleAct&articleID=1486 http://toothwalker.org/optics/chromatic.html http://www.normankoren.com/Tutorials/Chromatic.html http://www.bobatkins.com/photography/reviews/tamron_28_75c.html All of the examples are with Canon lenses. The purple or red lines on one side of an object with green or blue lines on the other. I saw it all the time in trees in the corners of the photos. Sometimes, as with these examples, it extends pretty far into the photo. The 24/1.4 L lens was also very soft in the corners. I examine all of my photos at 100% because stock agencies do. You might never notice the artifacts if you just look at actual size on the web, but once I've seen them, I know they are there and look for them in every photo. There are work-arounds to get rid of the fringing but every one of them degrades the photo in some way. I'd rather not have it to start with. Hope this helps. Tina Tina Manley www.tinamanley.com
