Third Party Manufacturers / Re: Sigma Announces 18-35 f/1.8 DC HSM Art for APS-C
« on: April 18, 2013, 10:01:41 AM »Don't get me worng; it's great to see fast glass coming to APS-C, and it's great to see Sigma throwing mud in the big boys's eyes. But "all" they've done is give APS-C some glass as fast (for the format) as what 135 has had for ages. It's high past somebody did this, but it's high past time precisely because it's no more remarkable than an f/2.8 zoom for 135 format.And insanely heavy, expensive, etc. I'm only aware of Sigma's 20mm f/1.8 as something that fast, that wide, and it has an 82mm filter. It's also not a good lens. Obviously 24mm f/1.4 is doable by several companies. Perhaps a 24-70 f/1.8 zoom would be doable for full-frame, but, I can only imagine the weight and price.
Now, an f/1.8 zoom for 135, or an f/1.0 zoom for APS-C...that would be something truly remarkable.
That said, should be much easier for APS-C; I'm hoping the results are good, because I'd definitely buy one
