Here's mine:
Having purchased the FA 20-35 this summer, I didn't need the 24mm equivalent that the 16-85 was giving me, and I was trying of switching between APS-C and FF on my K-1 (or having to explain about the black center rectangle to people who use my camera to take a snapshot). Using the modified 60-250 frequently, I'll be able to simply leave my camera on FF mode at all times.
The 28-105 looks fine. Slightly smaller than the 16-85, much smaller hood thankfully, similar build quality. I'm not a fan of the printed minimalist aperture/focal length print, I think the modern fonts on the 16-85 look better (I like the minimalist lettering when it's engraved, less when it's printed, looks cheaper).
AF appears just as fast as the 16-85, I'll have to test IQ to confirm, but so far I like it! The 16-85 will go up for sale shortly I expect.
