The cons: 3 fps.

Another drawback: It seems there are no faster lens than f/2.8 on the DFA/FA and Pentax 67 lineups.

Not a drawback for many types of landscape (and for most of my style). Maybe for some types of landscape and some types studio work - for isolation purposes.

The equivalent would be f2.2 on FF. I have three Zeiss f2 lenses and I rarely use them wide open in most of my landscape endeavors (infinity distances) because, frankly, they aren't sharp enough (Otus style ) in the corners wide open. If any of the f2.8 645Z lenses are sharp into the corners wide open or a stop down, that'll be good enough for me.

Rick Knepper, photographer, shooting for pleasure. It is better to have It and not need It than need It and not have It. Various RAW comparisons at Link below. Includes 5D3 vs D800E (new uploads), 5D3 vs. 6D, Zeiss lenses etc.
