K5 and Sigma 17-70 - Live music

Mine is the older non OS, non HSM version. The focus can be a bit sluggish, I do a lot of sport work too and it's not ideal for that.

Sharpness wise it fine now that I've set the micro-focus adjust to +4 on the K5.

I have a Tamron 70-200/2.8 which needs no focus adjustment at all so it just shows the importance of this feature. I certainly wouldn't buy a camera without it now.
