Nov 17, 2016 at 0:23 comment added Предраг Шепељ Actually I have similar issue on Canon 550D, in evaluative metering mode images are soft, but in spot metering focussing is spot on, so these things are definitely related but I don't have a clue how to fix it..
Mar 6, 2015 at 22:06 comment added K'' sorry for being late on this one, but yes it's true that center-weight was the most lucky one in this case, I tried again later and it's the same issue regardless of the mode. I tried manual exposure and the same result, all were fine with manual focus set by me. So I guess you guys are right it was auto focusing problem after all. I returned the lens for a full refund and I got the Rokinon.

Sep 27, 2014 at 4:45 comment added JenSCDC Have you tried shooting in manual exposure mode?

Sep 26, 2014 at 22:13 comment added Michael C @AndyBlankertz A sample size of four is too small if they are all very close to being the same. However, if a sample of four in each mode gives widely varying results it is enough to know the metering mode is not the cause of the difference.
Sep 26, 2014 at 16:58 comment added JenSCDC A sample size of 4 is too small to draw any conclusions. As boring as it may be, up that to 20.
Sep 26, 2014 at 14:28 comment added K'' @ths will try this and update the Q
Sep 26, 2014 at 14:20 comment added ths i suggest a control experiment: make four consecutive shots with the same metering and compare focus. related: are your results repeatable?

Sep 26, 2014 at 14:14 comment added K'' @MichaelClark that's true but this isn't the case here cause it wasn't low light and i'm not underexposing... it's just tight crop
Sep 26, 2014 at 7:09 comment added Michael C Setting ISO at 100 doesn't mean they weren't shot in low light. If you shoot at ISO 100 in dark enough conditions and underexpose by 3 or four stops you will get more noise than shooting at ISO 800 or ISO 1600. See photo.stackexchange.com/a/12489/15871
Sep 25, 2014 at 13:52 comment added K'' @michael they are just cropped tight. the iso was 100 in all shots
Sep 25, 2014 at 8:58 comment added Michael C Those images are awful grainy. I suspect the variations have more to do with your camera's ability to focus in low light than anything else. Your 1 in 4 lucky shot just happened to be when using center-weighted metering.
