I've been looking at a lot of shots I've taken w/ my 18-200mm, including landscapes, cars, architecture and many are within the 18 -35 mm range.
So I've been toying with getting a dedicated wide angle lens with better IQ than my current 2 lenses the DX 18-200 mentioned and a FX 35mm /f2D. The D lens is not bad but with my DX camera it's really more like 52.5mm, and at a recent car show I found myself standing about 10 feet back and in everybody way, and waiting for people to walk by. Using a tripod was even less practical. I switched back to my 18-200mm but the IQ is less than the D.
So, I've been toying with the idea of getting the Sigma 18-35mm F1.8 DC HSM A Nikon. DXO scores the lens at 28 for my d7100, and it's Sigma DC class lens suited for APS-C Nikon DX sensors, so the theory is I'd get a true 18-35mm with high IQ.
The problem is this: Reading the March 2014 issue of Shutter and they reviewed this lens, but indicated it would have a viewing angle of 27-52mm for Nikon APS-C cameras. The article also noted that Cannon 60D would have an equivalent viewing angle of 28-56mm.
I realize Sigma has to adapt their mount for Nikon APS-C, but that seems like a pretty significant variance. It sounds like Sigma is really marketing one of their DG series as a DC? At that rate you wonder why rate it at 18-35mm for smaller sensor dslr's.
