I also have both lens , and I use K-1.
Please note that if you use K-1, the AF speed of Tamron AF 70-200mm will not be slower than than 60-250mm SDM.
For quality, I use the modily version of 60-250mm on K-1, I think, it is generally above average for Pentax lens , I can rate 85 for the whole 60-250mm range , F4 aperture is no different with other aperture value, like F5.6 and F8.
For Tamron , the best point is it can focus very close and I will rate 90 for 70-200mm range , and the lens is good at 70mm F2.8 , but at 200mm , you need to stop down to F3.2 for usable image quality. I wonder why this lens is so strange. It just disappointed me on 200mm F2.8.

Sigma 35mm F1.4 Focus inconsistent on K-1
Any suggested solution ? I find that the lens work find on Liveview focus , but even I fine-tune the lens on AF adjustment menu , it cannot help since different distance the lens focus differently.
I also own the Sigma USB docking , but even fine-tune it still focus not very good all the time.
