So I got the 72XL, and as much as I see utility in having a similar FL lens that is smaller and (more importantly) takes 67mm filters, my financial situation disallows me from keeping it when I know that the geek in me is gonna reach for the 72xl, 90% of the time.
So, the newer MC SA75/5.6 in the newer black Copal 0 shutter w/ retaining ring. I'd rate everything (cosmetics, optics, mechanics) 9.5/10.
$500 OBO + shipping and PP.
Photos will go up later.
