Canon EF 50mm f/1.2L II Mention [CR2]

[Crosswind]

And who exactly needs a new 50L after Sigma's 50 Art? They won't beat it price/performance-wise anyway, if they even can outmatch the Arts picture quality.

But they can deliver a slightly faster 50L lens with much less weight/size than the art-series, without a compromise in IQ and bokeh. I'd always prefer the lighter one, even if the price is higher than Sigma's. Things I don't like about Sigma are the very bad quality control and support, not to mention the unnecessary weight of their Art lenses. Btw. if you need the best IQ go for the Zeiss Otus (if you don't mind AF & weight/size).

That, and the Sigma ART is a quite a bit MORE slow than even the current 50L. Moreso that just the difference between the rated 1.2 and 1.4 would lead you to believe. The Sigma ARTs lens coatings really do make it a bit "darker" lens and I've seen tests that make it a bit slower in terms of letting light in than you'd think, especially compared to the 50L.

I used both for video in very dimly lit bars in New Orleans...and the while the Canon 50L could turn nighttime into daylight almost...the Sigma struggled a bit in comparison.

I figure if I right now, before a 50L update....I'd like the Sigma ART for shooting stills if that's all I was doing, but since I'm doing a lot of video too, I'd like that extra speed and the look for video, and right now I can't afford both lenses...so, will hold out to see what the new 50L is like and what the price point is.

All the super-fast lenses are only that fast in the very center of the image. If you go just slightly to the corners wide open you realize that a 1.4 rated lens for example is mostly a 2.8 lens or so, except in the very center as I've said... All due to heavy vignetting. I'd give a thousand bucks more if the FF corners of modern super-fast lenses would be a bit brighter.

I do landscape-astrophotography. When you brighten up darker corners, you also raise the image-noise in that area to a certain degree. Or you can stop down a super fast lens to f2 or f2.8 to even out the incoming light and reduce vignetting, but then f2 and beyond isn't really "fast" to me anymore.

For portraits, this doesn't matter as some people like the effect of "framing" the subject and the fact that you are not shooting in the dark using high ISO. At daytime, vignetting is absolutely no problem because when you want to correct it, it doesn't affect the IQ at all and you won't notice it.

Other thing what's important to me is coma. That's also something you won't notice at daytime. But in the dark this can be very annoying esp. if you have city lights or stars in your frame. Still, most modern primes don't have appropriate coma correction like the EF 35 IS USM for example.

So, I wish, at least in the L-series, that Canon is giving me as good coma correction wide open as the Samyang lenses and a little less vignetting.
