So I recently purchased a 6D! I enjoy landscape and Astrophotography, but lately have been doing a lot of cityscape/urban photography at night. I live by Downtown Los Angeles which is where I tend to shoot.
Between these two lenses I like the 16-35 f2.8 but can't afford that sucker. Used, I did a quick search and saw the sigma 24-35 f2 and the 16-35 f4 go for about $750ish.. because I shoot ar night I'd prefer the sigma but the focal range seems limited at 24mm.. and the f4 on the canon is a bit of a bummer. Looking for any advise between the two.
Currently I only have a 50mm, went up from aps-c so I'll be building my full frame lens lineup.
