[QUOTE="aroy, post: 328605, member: 16090"] 50mm F1.4 in all versions is slightly inferior to the F1.8 versions. You get more DOF at F1.4 but vignetting, distortions and CA are generally more. For lenses corrected for these you need to consider the modern designs - Zeiss and Sigma. They have moved away from the classic Gaussian design (which had the minimum elements) to a complicated design with more than twice the number of elements and assiciated increase in weigh, size and of course price. Of course if you want the best they are their, but at a steep price. [/QUOTE]
