All those lenses in that range bug me a bit.
I can't fathom why when the APS-C sensor DSLR became the norm, that all lenses wider than the kit lens had to a be a zoom.
Canon had their 10-24, Nikon their 12-24 and later 10-24, Pentax their 12-24, and everything from Tamron and Sigma followed suit.
In the film era most of us were happy to own a 28 or 24 to something zoom, and then have a specialty "ultra wide" like a 20, 18, or 17mm. Sure, journalists liked the big 20-35mm 2.8's or 16-35 2.8's. But they were hard to lug around on vacation.
But when we went digital, nobody seemed to follow that logic, and all the wider lenses were fairly large zooms.
Why did no one decide to make a 12mm f3.5, for instance? Or 10mm? Especially if it could have been a bit sharper, bit more compact, and a bit less expensive than the zooms?
I guess market research pointed them in the direction they took. But nobody asked me what I wanted.
