This is a really dumb question, but are "Ultra-Wide Zoom" lenses the same as an ultra-wide angle? I see standard wide angles are very short, but no short ultra-wide angles. The only ultra-wide anything I see is ultra-wide zoom.
I'm looking to get an EOS Rebel T7 DSLR camera, but I'm also looking to get a 17-40mm Ultra wide-angle lens, but the only Canon lens I can find specifically says it's for SLR cameras. Does that mean it won't work for a Rebel T7 camera?
