K-r compatible with Sigma 24-60 f2.8?

Hi Everybody!

I've spent this morning e-mailing and calling Sigma technical support in order to determine the compatibility of the K-r with the 24-60 f2.8 EX DG.

The reason that I'm looking into it is that a forum user bought the lens from me, and it is not working with his body.

I have been unable to find any mention on the internet of an incompatibility between these two items, and Sigma does not have any information either. Abraham in their tech support department is going to contact Japan for resolution of the issue.

Does anybody here have a K-r with a 24-60 who can share their personal experience? Because Sigma had never heard of this problem.

Thanks!

Assuming the sigma is K mount, it should work fine. What isn't working for the buyer on the K-r? What problem is he/she having?

He states that it asks him for the focal length -- as if it's a MF lens or something.

That usually means the electrical contacts aren't working between the lens and the body. If another lens works fine, then its the lenses contacts. He can try cleaning them with a pencil eraser or some rubbing alcohol and a q-tip.

Has the aperture ring been knocked of the A setting? That would just be a guess.

Edit: Sorry, I did not remember it does not have an aperture ring. I did pull mine out and test it on the K-5 and it worked fine.

Seems to work fine

I did not have access to my wife's K-r yesterday but I was able to test the Sigma 24-60 with her camera today. Our examples seem to function just fine with no problem.
