| p.1 #10 · p.1 #10 · For 1D owners out there... the Sigma 18-35mm 1.8 works on a 1.3x crop! |
I've been mostly around f1.8-f2.8 but I plan on opening up the aperture for test stuff some later on. I think I read the maximum is f16 though.
And as for focal length, it's quite usable at 20mm. There is some slight vignetting but it's usable, and at 18mm it's just slightly more, but a little much for my tastes. 20mm is good enough for me though.
I'm a huge fan of both wide/ultrawide shooting, but I'm also a fan of using shallow DOF to isolate subjects and so on, obviously the two don't go particularly hand in hand that well (except for say, 24 1.4/28 1.8), but this lens changes that.
Oh, and additionally, at the wide end the lens hood does add a bit more vignetting, it goes away around 22-24mm, but I have not tested flare or shot outdoors. On full frame at 35mm the hood doesn't cause any issue.
