| K3II & 150-450 strange noises
Today when I put my 150-450 on my K3II & tried to focus ii sounded like a Harley was driving by  like gears going full speed with deep rumble??!! turned off camera & on and all was fine..and the next 50 shots were in focus...could this be the K3II body doing it?? (probably jealous as my K1 comes in a day or 2!!) or is it the lens. Tried to reproduce it but no luck..Tried with other lenses DA70,DA*300 & no loud spinning rumble. I really hope its not the 150-450, as it will be mounted on the K1 most of the summer  Any ideas?? | |

 Originally posted by darylk  I suspect the camera. Was it by chance mounted to a tripod and with SR on? If so, I'd guess the sensor shake reduction went a little berserk which has been known to happen (but I've never experienced it myself). My 2 cents... | |
