Very much looking forward to this one! As a new owner of both the 60-250 and HD 55-300, one thing I'd be interested in is a comparison of handheld performance with the K-3. Perhaps have the same person (or people) take several nandheld shots with each lens at various focal lengths and f stops, and compare the best and the range. Is it harder to handhold the 60-250 than the HD 55-300 (or possibly easier, with all that extra mass)? If you will have to shoot handheld, and are mostly interested in extreme telephoto performance (for photobirding, for instance), and just care about the center of the frame, is the 60-250, with cropping, a better choice or not?

Reason: add f stops
