Full Frame Ultrawide Angle Suggestions?

[M_Six]

I've been back and forth between the 16-35 and the 17-40. IQ seems mostly a wash as they are both excellent. Thing that sticks in my mind about the 17-40 is I already have the excellent 24-105 f4, so I'd be gaining only 17-23mm and no speed. Sort of makes it not worth the investment. The 16-35 will at least give me added speed for low light shots, albeit at more of a cost by a good stretch.

I also have the Roki 14mm f2.8 and I don't use it nearly enough. It's a great lens and not all that hard to focus. For daytime shots I set the aperture to f8 and either use Live View to focus or just guesstimate the hyperfocal distance and set it manually. At f8 the DoF is pretty much a few meters to infinity.


^^^Nice shot above, Joel.
