How difficult is it to acquire a palm grip for the non-mod 280 (1st or 2nd ver)? The one (I can't seem to find now) on the web seems to be a different unit for more modern lenses.
From another perspective - how did the grip rate on the useful/gimmick scale?
Oh and what (I'm unsure ungodly costly) type of 112mm filter was typcially used on the front of these babies? Straight UV -- or did it have to be some specialized Noctilux-glass version that was 3 microns thick and made only by 3-fingered Barvarian Trolls on odd-numbered Tuesdays?
Trying to determine the cost/benefit difference between a 280 that may be just the barrel and caps and one that is more fully equipped.
Oh, and after all this, any thoughts you have on the lens itself (you know the glass and metal bits that do all the work) would be welcomed.
