Rumored now by SAR to be only a little bigger than the 24 GM. That would be a revelation if the performance holds. I expected more like the ZA.
I'm skeptical it's about the same size as the 24GM but hope this is right.
Probably will be right in-between the 24GM and the 35mm Zeiss. And I'd be OK with that as long as it renders like the 24 Question is what is the price going to be
I don't think they can charge much if anymore than the Sigma 35 f/1.2 DG DN which costs $1,499 new.
Why? The GM is more expensive than the Sigma 85/1.4, the 135GM more expensive than the 135 Art and so on. Only because the Sigma is a 1.2, that doesn't mean it sets an upper limit, isn't it? I think 1599 to 1699 Euros is realistic.
The Sony GM 85 f/1.4 came out before the Sigma 85 f/1.4 DG DN was made for digital so certainly they didn't consider the price of that lens that wasn't even designed yet when they set the price for the 85 f/1.4 GM. There was the old Sigma 85 f/1.4 DG, but it was a lot larger and in several ways a much worse performing lens, so yeah they could charge more than that lens. And much they same could be said about the 135 f/1.8s. In both cases the Sony when it came out was smaller and better and designed for digital. The Sigma was bigger, had inferior IQ, and was designed for DSLR camera. In that situation sure Sony can charge more for the smaller lens with the same aperture.
In contrast, for this lens they are bringing out the 35 f/1.4 GM after the Sigma 35 f/1.2 DG DN has been out for awhile to rave reviews and that lens is a half stop or so faster and has exceptional IQ. No doubt the Sony 35 f/1.4 GM will be smaller (and hopefully quite a bit so), but that is about the only advantage it will have. It will be slower (i.e., a smaller aperture) and I doubt it will have superior IQ and this time the Sigma is built for digital. So it is not the same thing at all as when the 85 GM and 135 GM came out. Charging more for a slower lens just because it is smaller rarely leads to strong sales. They might charge especially at introduction even $1,699 but I wouldn't expect it to stay there for long.
I am not sure regarding the IQ of the hypothetical GM. The Sigma is great, we have two. But it has some weaknesses, too, like strong flares, it is super large and heavy (although I didn't experience it myself some people complain about issues regarding AF at f1.2), what about the f-stop and vignetting ...? It is really not that easy making something much smaller and additionally keeping sharpness, aberrations etc. on a similar level. Being an engineer, I therefore don't buy the argument that this is a minor thing and only advantage of the GM, because we don't know about performance yet.
