Originally posted by trivix OK, I will keep my Pentax. You guys have helped me very much! Today I talked to a friend of me who has the hobby photographie for over 10 years now. He said his Nikon lens makes similar sounds when it stabilize the picture. He says it is in 90% the SR. And 3 guys of you told me that their K30 makes the same noise. So I will keep it!
Mine does it even with the SR off. I suspect it has something to do with the seating of the SD card into the slot, as no card = no noise.
If you ever watch, even with the camera off when you insert a card the red light will momentarily flash.
