I think I'll stay aps-c a bit longer than planned. Certainly this should put pressure on Canon to become more innovative in the lens arena. Even more considering Sigma's success with their new 35mm f/1.4.

Looks like the ultimate travel lens! At 35mm it will also do for a decent portrait lens on APS-C!

I'm becoming more and more a Sigma fanboy :p

GEEZUS I didn't even know that 1.8 on a zoom lens was possible. This is incredible. Good job Sigma.

Don't expect it to be cheap. It's a unique lens, and Sigma will take its toll for it. Also, it seems that they didn't spare on special glass and on glass in general (810g!).

Judging from the way other ultra-large-aperture zooms are designed (e.g. the Oly 35-100 f/2) I'd guess that the design is basically a 35-70 f/3.5 with a reversed 2x teleconverter at the back.

I imagine that an FF version of this concept would weigh well north of a kilogram (& cost well north of a kilobuck).

Kudos to Sigma for being innovative once again. Hopefully this will show C & N that there's real demand for more large-aperture lenses.

I've said this before and I'll say again, do we really mind a 1.4 kg lens that covers 24-70 at f1.8? We carry the 70-200 with that weight with no issues, so why not a 24-70?

I think there would be problems in doing a sharp lens with those features. If you look at the MTF charts for this Sigma it's clear that border performance suffers quite a bit wide open - and it's only a 15 MP APSC.

Good size comparison to give you an idea of size and weight with something you might be familiar with, but not a fair lens comparison...the Canon is for FF cameras..not just APS-C.
Still... A very exciting lens! I have the new 35mm f/1.4 and it ROCKS!
Can't use this one though as I am a FF user...but I hope the specs are incredible....I want the whole Art Line to be fantastic!

Quick someone gripe about the lack of OS! ;D I kid.

Seriously though, great job Sigma! Love my trio of Sigma 1.4 primes!

I'm not gonna get too excited for this until we see actual photos and MTF charts.

And it being for crop bodies only is a huge disappointment. I get that FF lenses are more difficult to engineer, and this is a good start... but I would have loved for this to be a FF lens.

But regardless, kudos to Sigma. They're clearly stepping their game up of late.
