I really like 24mm for landscape photography. I have the 24/2.8 at the moment and am fairly happy with it. I am really just after opinions as im considering trading it for another 24mm lens as I know all the competitors are well regarded.
Background info first. The lense would be used at f8-f13ish for the majority of the time. It will be used on a full frame camera. Full frame is one of the issues with the current 24 as it vignets if used at 2.8, which I do sometimes use. Secondly Id do not really mind whether the lens can do 2.8 as opposed to 4.0. I am more for IS than lower aperture as IS can keep the f-stop smaller and give similar shutter speeds.
The lenses I can for see as choices are the 24-105, 17-40, 24-70 and the 24L. Im really just after opinions on which of these lenses deliver best colour, sharpness at the pre mentioned fstops and any other reason.
As far as simple flexibility I know the pros and cons of each. I would like the 17 so I can combine my wide lenses even though I rarely want wider than 24, I like the 105 because I do more tele-landscapes than I would expect and it has IS, I would love the option of 1.4 (but not sure whether id rather is in a 35L or 50L later on).
So all im really after is a comparison of Chromatic abheration and colour and sharpness and real world experience. Price is not really an issue as I dont see any of these lenses as wasted money.
Thank you to anyone who can help me out.
