Sigma SD1 and Sigma 18-35mm f/1.8 ART lens equivalent focal range?
1

I recently upgraded my Sigma package from a SD14 w/ 17-70mm 2.8 to a SD1 Merrill with 18-35mm f/1.8 . . . I haven't picked up the 18-35 yet but I have gotten the SD1 and must say, it feels like a subtle upgrade, but an upgrade non the less. It seems easier to take good photographs with the SD1, less colour issues, and all around the SD1 feels like a big quality upgrade. Even the shutter sounds much 'beefier' akin to medium format. I'm going to be picking up the 18-35mm ART lens this weekend, but I'm confused how Sigma qualifies it as a 18-35mm. I'm wondering what the equivalent focal range (to 35mm) the 18-35 would be on the SD1 (1.5x crop factor) . . . Or because the lens was intended for APS sensors is the range actually a 18-35mm equivalent on smaller sensors and thus named so on the lens? Thanks for any input. I'm really looking forward to trying this lens on the SD1.
