had it now for 2 days. my first impressions are it has alota-lota glass,now I know why its called the keg.lol. Image quality wise I batting .995 with this lens,straight out of camera ,color ,contrast and sharpness are sweet. The only negative is the ca when wide open in bright contrast but thats to be expected with a 1.2 apeture.Sharpness wise it beats my sigma 50 f1.4at 1.2 and its right with my 135f2 I have'nt pixel peep them or compared them its just from knowing your lens. Anyway,I always favored the 50-200 focal range, so maybe thats why Ilike it so much. here;s a pic shotwide open and 100% crop, no pp. gotta find a duck. time to go play soe more
