Originally posted by treebeard I will wait for the K-30 to arrive. If it's a lens/body combo it's not the end of the world...I mainly use my K-01 with my Pentax SMC-M 100/f4 macro lens. Is there a way to tell what firmware the Sigma lens is on?
I don't think so, but I'm not an expert on this. If you're fine with using the viewfinder to focus the lens and think you'll never use the LV on your K-30, then you could just keep the lens as is. But if you do want LV focusing (whether on the K-30 or K-01), you would need to send the lens back to Sigma to upgrade the firmware. You would have to pay for the cost of shipping naturally but I don't think the actual service is that expensive. Let's just hope that the autofocus issue is limited to the lens firmware and not some other problem. Once you get your K-30, you can confirm this!
