Yup, I wore my glasses this morning because my eyes didn't want to deal with contacts due to allergies, and I finally had to put in new contacts because I couldn't stand the red/blue fringing on things I was looking at when i would be at an odd angle. Actually, I get a bit of CA from my glasses as well, when I get way off axis. I'm sure that there's a solution, but I suspect that fluorite lenses would be both heavy and expensive. Tom

That's what you get from the light not going through the lenses perfectly, and refracting some of the spectrum out of where it should be...

SuzyView Cream of the Crop  More info | Sep 12, 2006 21:47 | #10 That's interesting since I have 20-20 vision but have special glasses that straighten out the light for me so I see things darker, like USM for my eyes. So, no CA, just USM for me. Suzie - Still Speaking Canonese!

Even though I tried, I can't get any CA and my pictures came out sharp... WTH? Darn piece of crap not being enough of a piece of crap. I thought it could be counted on to give me CA. Hehe.
