Hello everyone, I would like your opinion on my problem. for a few months now, I dropped my K-50 (as it has a few issues) for a new K-3 II. however, I soon discovered a problem with it. most of my pictures are out of focus. I use most a pentax 16-85 and a sigma 17-50 2.8, but with all my lenses the results are the same. I use mostly TAV or P mode, single focus point. i took the camera for a small test when I bought it, with the 18-55 lens, the one I had with me then, and noticed that most pictures were out of focus. but I didn.t mind it that much, as I thought my 16-85 is a lot sharper, and will perform a lot better, but it didn't.
I took the camera back to the shop, and they recalibrated it. it seemed to perform somewhat better after that, but not by much, and soon, I was back where I started. same results with my sigma 17-50 2.8. It seems to me that it can't focus properly when you use the long end of the zoom, but it's quite sharp at the short end, for whatever the reason. after an hour or so, I turned off the SR and it seems that it improved the ratio of sharp pictures.
Iater on I will try to do some microadjustments with a lens cal (I've tried that before with 16-85, 18-55, and 50 1.8, but not with the sigma lens, but without any results). I really want to figure this out, as I love this camera. it takes outstanding pictures (when they are in focus...), but at this point, my K-50 is a lot sharper than my K-3 II. so, it's either the user (K-3 II is a lot less forgiving than K-50), tho I can't really belivethat I screw up almost all my pictures with every lens I got (it doesn't make sense, to me anyway), or, the camera has some problems. I don't really want to take the camera back to the store, but I will if I have to.
also, I've noticed that the shutdown it's not that fast, it takes a couple of seconds to shut down, and the top plate a second after that. and after power up, either from off, or idle, it makes this wierd scraping noise, before I can use the lens, like it has some kind of locking mechanism for the AF, when it goes idle.
any ideas? anyone else with the same problem?
