Thanks! Yeah, I need a working AF as well, but I don't have the pressure of, say, a wedding photographer. And if I absolutely can't afford to miss, I use the 24-70. Or maybe try the 50 at f2.8, lol.

With regards with af bug, I am not sure if I am saying this correctly but I have disabled that halfway button function on the camera. So now, if I let someone take a picture of me using my camera, I need to explain the whole process of pressing the Af button or the pic will be just a useless unfocused shot. Lol
Yeah I have the same setup. I also use the AF-ON button for AF and only metering on the shutter. But if I start metering by holding down the shutter button halfway, like you normally would do to start AF, and then push the AF-ON button, it sometimes won't focus at all. So then I have to release the shutter completely and push the AF-ON first and then the shutter. It's very annoying ..

I hope you find a fix for that soon Viggo. I'll be surely pissed if I have it on my camera.

Yeah, well we're all either fanbois with no objectivity or Canon-bashers with no objectivity, right? :
Two reviews have noted AF issues with the lens, other reviews have not (though many reviews don't actually test AF performance). Maybe Roger Cicala will get a large batch and provide some solid evidence one way or the other.
heres hoping roger can get a batch and test. his batch testing seems to provide the most objective and comprehensive analysis of lenses available. also if there are issues I hope they can be sorted with the sigma dock and the issues aren't random and all over the place like the old 50 was (well for me anyway) its odd that my wifes 5Dmk3 seems to have no problem with this lens and is providing amazing images wide open with remarkable AF consistency where as for me it was all over the place...

I read a review Michael Reichmann's (Luminous Landscape) review of the DP2M (which uses the Foveon X3 sensor) that raved about it. Was it credible? Well, he listed one of the cons as "poor image quality above ISO 400." I find it hard to rave about a camera with ISO performance similar to some of the earliest CMOS sensors, but if all you do is shoot at ISO 100, maybe you can consider a Sigma body.
Viggo said:Hopefully something can be done. But I will take a stab at it and say this is done by Canon, a small disturbance in the firmware that handles AF communication. Would be VERY interesting to try my lens mount converted to a Sigma camera.

I'll keep checking though....

That's great, thanks. I'm glad people have working copies, keep us posted! I must say I'm beginning to really doubt it all. Does it make sense that I buy two sigma lenses and they both do the same while 98% of other people have flawless copies? Sorry, but I don't think so. It's just a little far fetched my luck is that bad, especially since we all got from the first batch. And a fellow Norwegian in Eldar also experience the same issue.
If anybody use it on a different body than the 1dx or even has that and another body, does the focus act up on those bodies as well?
And I was thinking the same thing about Nikon and the Sigma, maybe I'll I sign up there and start a thread about it.

I think you have the worst luck of any person on the planet with lenses...

I did a google search on AF issues with this lens and it apperas to be throughout Nikon and Sony too. Same thing; AF apperas to drift over time.
Sporgon said:@Viggo, I re traced my search links and my apologies: the flicr boards were dealing with the old Sigma 50 1.4, not the new Art. I'm not picking up the CR threads on this either though, so will keep looking.
