Wowww! I wonder if it'll be sub $1k and wipe the floor w/ Canon's 24mm 2.8 IS USM and 1.4. I'm excited about this lens, but prob won't be able to shell out for it.

I assume the AF issues will remain, but hey, I could be wrong. I also wonder about its size.

Hi meywd!

I've just read the German press release:
http://www.sigma-foto.de/fileadmin/content/pressemeldungen/SIGMA_PR_A24.pdf

They say they have managed an "outstanding correction of sagittal coma" by "positioning aspheric elements on the rear" and so on. So they have aceived "high IQ performance from open aperture on".
Okay this is just a press release but sounds promissing.

They also mentioned outstanding low CA by the use of FLD and SLD elements.

Let's wait for the reviews.

Here's the product page from Sigma America with more technical information:

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

edit: Now you can read: "Coming Soon" ;)

Going by the 77mm filter thread, the lens looks to be about the same girth as the 50mm Art, but definitely shorter. Comparing the proportions of my 35mm Art against the picture of the 24mm, I believe the 24mm lens is fractionally shorter than the 35mm.

Edit: 85mm diameter x 90.2mm length so, yeah, my estimation above is right. At 665g, it's the same weight as the 35mm.

Hi Maximilian

Thanks for the link, yeah I checked the press release but as you said it's better to wait for the reviews.

Where are all of the messages about how it won't autofocus correctly without sacrificing some virgins and doing a rain dance?

I actually tried that with the 2x35 and 2x50 I had, didn't work, so I will most definitely not buy another one. I'll keep the rest of my virgins, thank you...

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

Not so. At f/1.4, focus is really difficult on 24mm. I had the Canon 24 f/1.4, and it missed focus most of the time when the focal distance was greater than 6 ft on my Canon 5D2. I sent it back because of AF issues. It's difficult to tell when you have good focus on a 24mm unless the subject is really close. I am told that this lens works better on the 5D3, but I never gave it another chance after my 5D2 experience.

I'll be interested in this Sigma if it performs better than the Canon in every respect, including AF. Wait and see time.
