At least with 24mm ( on FF ) AF isn't as critical.......

I will likely try it.
I had the original Canon 24 f1.4 (so compact and wonderful useful-even for flowers) .. and I rented a few times the 24 mk II ...the newer one had lower chromatics, a bit sharper in corners...but bokeh was not as good as original (imo) and shaded in corners worse than original...
so I waited... then I GAVE my brother my original 24 f1.4 ....for his 50D I gave him.....
and just last week I missed it ...so much... when shooting in dark clubs ... wide and fast is so valuable in a dark little club. my 35 A sig performed quite well as usual...but I sure miss the 24mm.... I could stand next to guitarist and yet... get the trio in the photo.

I remember the original Canon 24 f1.4, had focus problems ...especially out at 5-10 feet as described, However, I sent back to Canon and when it returned (they re-electronics it they said) it was just great all over. My sig 35 f1.4 A hardly ever missed focus on 5D2. And I got significantly more reliable focus on my 5D3 with Canon 24mk I, sig 35A and my 85L II....... vast improvement...especially the 85L.

I am getting the 11-24 Canon zoom ($gasp$)- so I am gonna have too much overlap for my normal tastes - but I NEED fast and wide...... for sure focus will be more difficult at 24mm wide open - especially in the 'dark' (imo) ..

but I will try this one....
I hope for good coma, sharp edges, low distortion, low CA and reliable focus...to come with it.

I thought the 85 would be my next sigma....but I kept the 85 f1.2 II .... after a long wait

I am never gonna get another guitar.... I guess... sigh

I am really hopeful about this lens too, when my 24 f/1.4 mkII was well focused the shots were great. It really is a special focal length / aperture combination!

This should be an interesting battle with Canon & Nikon as both of them have well-regarded 24 f/1.4 lenses. Yes, coma, and vignetting are issues, but they are very sharp lenses. This was not the case with the 35mm and more so with the 50mm lenses, so unless the price is right, I think it's going to be a tougher sell to anyone other than people who shoot starry skies (assuming excellent coma correction).

Also, given Viggo and Eldar's experiences with the Art series AF, I'm staying far away from this line of lenses.

I'm particularly curious about the coma and astigmatism for exactly that reason - nightscapes. I don't really care much about its AF performance, but of course price/performance ratio is key.

Forgive my ignorance, I thought the 35mm and 50mm Art lenses were touted as being very sharp? was that not the real world observation? I haven't kept up to date with gear reviews lately.

Great news.
Me happy ::)

I guess I wasn't clear on that - what I meant was that when shot wide open, the 24L II is very sharp, the 35L is modestly sharp, and the 50L is a bit soft. The Sigma Art lenses beat the 35 and 50, particularly the 50L quite a bit wide open. The 24L II is going to be a much bigger challenge on the sharpness side, but it's vignetting is considerable and the coma in the corners is terrible for stars.

24 1.4 comafree for ~700€ might be interesting. (35 Art vs 35L is the same price difference)

85 Art... Sigma build for Canon and Nikon. (and Sony) I've heard (i have no idea), that f/1.2 isn't possible on Nikon side due to smaller distance between lens and sensor - so a 85 1.2 Art should not be possible, correct?
Maybe 85 Art 1.4 is the maximum possible, but with a nice sharpness and faster AF this would be ok, i think. But I am no portrait guy, so 85 isnt my lens anyway.

Off topic, but I would say the ultimate landscape astrophotography lens would be the Samyang 14mm/2.8. But I guess not as fast.
Depends on your needs... for meteors and aurorae, speed is important. Meteors also tend to look less impressive at 14mm, and composition becomes more challenging. I certainly would prefer a good 24/1.4 :P

I don't find the EF 24/1.4L II that sharp. Only when stepped down to 2.8 does it become reasonably sharp, and then only as sharp as the EF 24-70/2.8L II zoom (worse center, better in the corners). And as mentioned before, the coma is absolutely terrible. So I find there is definitely room for improvement.

Indeed, though the 50 and 35mm Art unfortunately have quite poor coma wide open. The press release gives some hope, but I will also wait for a reputable review. A low-coma 24/1.4 would be a dream. The Samyang 24/1.4 seems to be the best so far in that respect (though don't know about the crazy expensive Zeiss).

Which fast 35mm lenses have less coma than the Sigma Art? I haven't tried all that many, but even though it wasn't perfect the copy I briefly owned was far better in terms of coma than, say, the Canon 35mm IS.

I don't really know, haven't tried any other. Perhaps it's the best, even though it's no good [wide open]. For a long while I thought it perhaps impossible to make a fast 24mm with little coma, but then the Samyang 24/1.4 came along and proved me wrong. Maybe the coma-optimised 35mm design just hasn't happened yet.

I believe the Canon 35mm is more widely regarded as sharper than the Canon 24mm wide open. In fact, in my experience I felt that the 24mm was not very sharp except for the center wide open. Have no experience with the Nikon, of course.
Another aspect is price. One big reason for people buying the 35A is the lower price. I am sure a lot of people will go for a 24A if it is $ 500 cheaper than the 24L.
I agree with staying away from Sigma lenses due to AF issues though. A pity...

Here's the product page from Sigma America with more technical information:
http://www.sigmaphoto.com/product/24mm-f14-dg-hsm-a?link=feb-m-24mm

Funny, they state there: "This product is discontinued." ;D

Boy they aren't even waiting until a few months after release (24-105) this time. ;D

More seriously, it sounds nice, especially if the N24-70 isn't so great at 24mm and the 5Ds doesn't have the better DR that a few are now claiming (although it all seems like reaching to me) and one goes N.

This and any other Sigma is off my radar until they have fully proven that they have fixed the AF issues. I´ll never go through the pain I had with the 35 and 50 Arts again ... Imagine an 85 f1.4 with that AF ...

Same here. Not even an attempt yet to fix the 50mm Art with a firmware update.
