Forgot to add before that I also use the DFA28 - 105 for WR capability and when traveling (the k-01 for traveling very light).

I have one and its not too bad on the K-1 in that:
1. Covers the frame from about 100 - 300mm.
2. Center is as sharp as on APS-C (not surprise there)
3. Corners sharpness lags a bit and benefits from stopping down a stop or two (but honestly better than I was expecting).
So I was using it for a while but now have a cheap (second hand) Sigma 70-300 APO (

1. Obviously full range full frame coverage
2. Center sharpness similar
3. Better corner sharpness
4. Rubbish build (zoom sticky at times).
