I've done some focus adjustments. Thankfully the twin lens kit was pretty close to spot on, the 18-50mm had a minor adjustment (-2 or something). All my others are good with one exception, the Tamron 17-50mm F2.8.
It seems to want to front focus heavily, just barely hitting the expected focus point with -10 adjustment. At 35mm its a similar story but 50mm is better, it needs to be sent in.
I'm actually impressed with those cheapo DAL kit lenses, for the money at least. Sure they have some vignetting, distortion and lack of sharpness open wide but they're light as heck on the body and stopped down pretty impressively sharp (at least in center) the ISO required doesn't seem to be an issue which makes them eminently more usable than on my old K20D.
I'd trust the kit 18-50 over my Tamron at the moment, sadly
I've taken a few video clips over the day, mostly deleted though just fooling about. The Autofocus racking during filming is very audible and the AF often racks past and back a bit before locking, but the idea for decent film would be manual anyhow I would imagine.
Battery performance has been pretty decent, it's basically out of juice but its had a thorough working over with me doing AF tuning movies etc.
The thing that irks me about the grip I think isn't so much sore/crampy (Today I had no issues with soreness etc) but more that my fingernails just slightly dig the soft textured rubber where it ends on the body - A close trim should sort it haha
