would greatly appreciate if anyone could recommend a field flattener that would help fight the field curvature problem I am having with my modded Canon 300D and ED80.preferably one that didnt break the bank, if such a thing were possible
funny thing I never noticed it much with the stock Canon-was there all right just not so pronounced -but the modded Canon comes to focus at the very end of the focuser travel range, I am using a 2 inch UV/IR filter and the field curvature effect is driving me nuts
thanks in advance for any suggestions
