This is my stardard lens for the K-5 and initially I wanted to use it with my K-1. But I only used it once or twice since I wasn't happy with it. It's simply an extreme DA-example with narrow image circle. In the end I bought the DFA28-105 instead. Similar feeling but great results - the right choice for me.
Originally posted by mee On my K-1 with the HD 55-300mm WR I just tried it indoors (so low light since it is night time here). It seems to vignette hard from 60mm to around 150mm. That is to say, at 55mm it seems ok
Seems to be similar to the DA55-300PLM. My observation for this lens classified by open aperture:
f/4.5: 55 - 63 - 70 - 78 - 88 - 98 - 108 -120 - 135 mm => dark corners up to dark image circle areas and back - very bad in the middle range, widely usable in FF Square mode, allows crops bigger than APSC area
f/5.6: 150 - 170 - 190 - 210 - 230 - 260 mm => FF compatible, existing corner vignetting can be mastered
f/6.3: 300 mm => dark corners, usable in FF Square mode, allows crops a little bit smaller than FF area
