new (used) 5Dii - what lens equivalent to crop 10-22 - 16-35 or 17-40?



Recently picked up a good used 5Dii. I also have had a 7D for few years. Not selling 7D, as the two bodies complement each other. I shoot wide range of subjects, and the wildlife/birds/events will be handled w 7D and its speed and best use of the longer focal lengths.

FF will mostly be for landscapes.

As most lenses have been added for crop cams over the years, trying to decide on which route to go for the wide/stn range zoom. Hope to get some feedback from those with the similar or same (e.g. 7D/5D body setup)

Present lens lineup:

EF 50 1.4

EF-S 10-22 USM

EF-S 17-55 IS USM

70-200 L F4 IS

100-400 L IS

1.4 II extender

The EF's stay and the longer range is covered fine. While I love the 17-55 and 10-22 on the crop, I'm considering selling the 10-22 and looking at alternatives for landscape on the wide end for the 5Dii. The obvious contenders (that won't break the bank) for FF are

16-35 2.8 versionI

advantage - similar to the 10-22 FOV on crop, faster 2.8, seals, build

17-40 f4

advantage - lighter and cheaper than used 16-35 but not as wide, slower, but I'll likely do landscapes in the f8-11 anyway on tripod.

Sorry for the 'long story' but hopefully anyone whom was in the 'same boat' when going to FF and already had a crop ultrawide can offer their thoughts.

Anyone go from EF-S 10-22 to 16-35 on FF and find distortion or sharpness better or worse?

17-40 thoughts?

Thanks much!
