Which is fine until you acquire a lens that needs v1.40 or higher, which could be a Sigma lens.
Sigma is known for their odd firmware incompatibilities especially on Pentax. That's why they have the USB dock to update the firmware instead of you having to send the lens in.. It's long been rumored that Sigma reverse engineered the communications protocol on Pentax lenses which leads to the incompatibilities.

But not perhaps with firmware v1.40!

Can you update the firmware on the Sigma?
