K5 Mirror Flop | Flip | Flap - Ummmmmm

Ok - well, K5 is acting a little on the strange side. During Hi-Speed Burst shooting it SOUNDS and FEELS like the mirror/shutter gets out of sync; it's really hard to explain actually being that it is still taking the snaps correctly.

So, instead of the smooth
CLICK | CLICK | CLICK | CLICK | CLICK <- fast at 2000th and greater

It will be something like
CLICK | CLICK | CLCLCLCICK | CLCLCLCICK | CLCLCLCICK - almost like a dragging feel and sound

This is happening every so often and not at every interval I shoot in burst - so I may have 2 or 3 rounds where it works perfectly then I will hit a round where the strange behavior happens. Has anyone experienced this before?

What's happening with the output of it? Are you getting black frames, or partially black?

No, still getting images fine - but I think it may be skipping an image or 2 in the sequence (like maybe getting 1,3,5,7 and not getting 1,2,3,4,5,6,7), hard to tell though since the action is going by so fast. It's either that or its only giving me 3fps instead of 4 or 5fps like it should for the given shutter speed...

If you're not getting damaged output, and the file numbers are in sequence, I think you're quite lucky. At least, it could be a lot worse.

I wonder, if you took a digital stopwatch that does milliseconds, if you could figure out what it's missing, if anything. It might give you some indication if it's really shooting/flopping erratically, or if it just sounds like it.

You can also figure out fps by recording the sound the camera makes, and then checking the time between the series of pulses. This wouldn't help to show any variations in exposure, or anything like that (which is why shooting the stopwatch came to mind first).

Photograph a spinning rainbow wheel, if it's OK you should get photos in a sequence. If any photo gets left out you'll see the jump.
