so far, so good on that score - I do rely (probably too much) on focus confirmation, plus have an O-ME53 on the K-5 IIs.... about the only thing left to do would be to change to focusing screen, but in the limited amount to time I've been shooting with the 55/1.8, I think I've been getting good results...
to be fair, I usually shoot in brighter lighting conditions, or I switch over to LiveView for better overall composition and focusing...
