Wondering if anybody with a K-3 also has the Sigma 70-200mm f2.8 HSM lens, and what your experiences have been with that camera and lens combination? I have a K-5 with that lens and, while I like the combination, I wish the K-5 would have more accurate AF (mainly shoot my daughters hockey with that lens). I find I have to delete more images that I think I should because the K-5 missed focus. Any info from K-5 to K-3 upgraders would also be appreciated.

Thanks in advance.

Mine seems to work fine on the K-3, but I have not tested it in detail.

Ditto, it works just fine.

As I did with the K-5, I feel like I need to bias the meter down 2/3 of a stop to get the same exposure and richness of colour compared to Pentax lenses.

Which version? The newer OS HSM one, or the older Macro II HSM one?
Probably both would work better on the K-3, I suspect, due to the more evolved AF system.

I have the older 70-200mm f2.8 Macro HSM II model.

How would you guys compare the autofocus speed and accuracy compared to the K-5 (with this lens or even in general)? Do you feel your getting less missed shots and more keepers?

The newer OS HSM one seems to work pretty well
