I've lost trust in it, for the most part. I don't carry it much anymore since it's so big and heavy. I use it only when I have to.
I'm willing to give it a shot after the FF comes out, see if that does better. I get it won't be making full use of the FF capability, but if it can produce nice landscapes, then I may consider keeping it, since the 27-52mm equivalent FoV is still pretty good. And I've got a lot of good filters for the lens...
Quote: The focusing is good at close proximity though it can fail - something like with 3-4 meters range, whereas at greater distances, it will fail more often than not. Fortunately, I do not need to be as quick to take photos when shooting over greater distances, so I manually focus using LV.
And that's the rub. It makes it mostly useless as a landscape lens, where in this focal length is most useful, since infinity focus is...shaky, even at f/8 or f/6.3. I can get shots that look nice at screen size but pixel peep them and it's clear the focus is just off. I used to think it was limits of resolution of the camera, but the FA31 has showed me otherwise.
Originally posted by Stagnant Some days ago, I attended a metal concert in one of the local clubs and it was the first time ever, that Sigma 18-35 and Pentax would refuse to focus at all, no matter what settings I used. I photographed multiple gigs in the club before, but apparently this time the light was way too dim. I did manage to make shots, but it is not quite clear, how much in focus they are, because only the silhouettes of artists were visible.
I've found that in low light, it's pretty much useless. It rarely focuses correctly.
I used to view this lens as a f/2.8 lens that sometimes worked below that. After reviewing a lot of my photos from the summer, I've come to view it more as a...f/8 lens? Not sure.
