i can understand people that only have 1 body having an issue and wildlife people typically will like to shoot landscapes as well as wildlife because of their interest in nature
and as I pointed out the tokina 11-16 works on current APS-H cameras without vignetting from 13mm to 16mm
13 mm = 16.9mm so pretty much has that covered
so there is an option
of course there is also the 14mm L and a few other options around in the primes
and rare i mention the 8-15mm
