Quote:I only know two: Nikkor 14-24mm f2.8 and Sigma 12-24mm.
The normal UWA's have overlap (thankfully):
Nikkor 16-35mm f4 VR
Canon 17-40mm f4 USM
Canon 16-35mm f2.8 USM
Nikkor 17-35mm f2.8
Zeiss 16-35mm f2.8 SSM
Tokina 16-28mm f2.8
On APS-C SLR there are only two examples of lenses with less/no overlap (depending on which APS-C standard zoom to put them next to), the Tokina 11-16mm f2.8 DX and the Sigma 8-16mm DC.
Pentax and Tokina 12-24's also.
The other UWA's that you list are for FF. They are not really UWA on APS-C. The 12-24's are 18-36 FF equivalents...to the lenses that you list.
