Originally posted by excanonfd I am not seeing any instances of focus peaking happening as I try to focus Rokinon 85/1.4 @ F1.4 on a Q with v1.10 firmware. I've visited Pentax support sites to see if there is any mention of Focus Peaking having been added to the firmware, there was none. I would have thought a new focus technology that debuted with the K-01 being added to the Q via the firmware update would surely be announced officially by Pentax Ricoh, I see nothing of the sort.
Hmm, I've updated the firmware, and I have the same Rokinon lens. Focus peaking is most evident when shooting a consistent, slightly patterned item such as furniture fabric or a blanket. It works very similarly to the K-01 (taking into account the substantial "circle of confusion" sensor size difference, of course). The Rokinon on Q probably exhibits a more-distinct focus peak at f/2 because the lens picks up contrast and sharpness with the lens stopped down. In fact, as I do studio tests, it gets easier to predict not only how sharp a lens will test out, but where MTF peaks just using the focus peaking and noticing "snap" as focus is achieved. On a very soft lens, it is difficult to see focus peaking, let alone finding the precise focus point.
