Hello, my name is Kevin and I have LLD. I also think I've become a glass snob. UncleFrank said I must have 25 posts before I'm allowed in the "For Sale" forum so I figured I'd try to get there a little faster. But seriously, I currently have an 80-200 but want more reach for wildlife photography. I'm not opposed to an extender but would like some opinions on a couple of primes. Unfortunately, I don't have $3000+ to spend on one so I'm considering two specific manual focus lenses: 400 f3.5 ED IF and the 500 f4 P ED IF. Does anyone here have these lenses and would mind sharing their experience? Or are there others in the same range I should consider? I'm not opposed to the 300 f4 AF-S for about the same $ as the above. Mostly, I'm interested in the best optics. AF would be great but I'm afraid the length isn't quite long enough. I also figure the discipline of honing my manual focusing skills will be a good exercise. Any thoughts?
