Start-up Noise - K-5 IIs
Picked up my new camera last week. Last night, for the first time, I noticed that the aperture actuator in the camera body makes a brief buzzing noise when I first turn it on, or when it wakes up from sleep mode. With the lens removed, I can see that the aperture actuator moves slightly when this occurs. The behavior is consistent and repeatable everyone, but I didn't notice it previously. The actuator still seems to function properly as the lens stops down during exposure or with the optical preview.
Is this normal K-5 behaviour that I just didn't notice before, or is something I should have Pentax look at (obviously, still within the warranty period)?
Thanks in advance!
