I know by the title this may sound trivial, and in reality it may be. However I would like to clear something up and get some advice from the advanced. When I first got my D60 in April, I couldn't understand how the quality of the kit lens was poor. However after getting a 50mm 1.8 and then the 50mm 1.4, I automatically realized the difference between the two. The color was more accurate and vivid, images were sharper, and the ability for a thinner DOF was my favorite change. Now I am in the process of saving for some new glass, and I've been doing quite a bit of research. The main question I have is sort of general, but i'll give it a shot. When people on the forum talk about great glass and how it's better than the kit glass, would a 85mm f1.8 fall into that category? Or would only a 85mm f1.4 be considered good. Also, are DX lenses considered good glass? Because I've noticed at least from Nikon's line, their BEST lenses are full frame, and they have only a few top of the line DX's (at least for the ones I want). I already decided that for me, I would rather save the money and get the fastest I possibly can, but I am just curious. What will be the image quality differences, regardless of DOF, between a 85mm 1.8 and a 1.4? Thank you!
