here's a couple of shots after calibrating
#1 (taken wide open at f1.4)
#2 (taken wide open at f1.4)
here's a couple before calibrating ):
difference is huge if you can tell. this lens is a keeper if you get it nicely done.
go to the shop, request for a few copies of the lens to test it out. take a couple of shots at is minimum focusing distance. like my first shot. test out a different f-stops. 1.4, 1.8, 2.0, 2.8 and 3.5. these are the 4 i normally test.
after which you should test the lens at 3metres and beyond. i had problems with the back focusing, so images 3m and beyond was not focused properly. also, test with all 4 f-stops.
sometimes, even tho you test, it will still have minor problems which the sigma svc centre can fix for u. i got it fixed just ytd.
well done,after caribration was very sharp with wide open.very good
i have sigma 50/1.4,look the pic just like ur befor caribration,i buy last year,i think need to take time to go for adjust .still under warranty.i buy local set 2.5yrs warranty.
