You ULF People w/ Big Lenses... BIG QUESTION!!
I'm assembling a 5x12in kit and my biggest diemna has been WHICH 210mm WA. I've bought a 210 Apo Symmar, 210 G-Claron, and 210 Graphic-Kowa. From what I've read the latter will give me the coverage and corner-to-corner sharpness I lust for and the former two will NOT. Please provide YOUR experience.
I also have:
72 SA XL for 5x10 (barely covers)
110 SS XL for 5x12 (barely covers)
150 SS XL for 5x12 (with wiggle room)
210's (as stated)
600mm plus (later... probably Nikkor 600/800 Tele)
