My k10d has stopped stopping lenses down properly.
None of my lenses now work correctly at large f numbers.

It looks like the device in the throat of the camera that drives the lever on the lens isn't operating.

any idea how much this is going to cost me?

Before you send it away, do you have a grip attached?
If so, move the Av e-dial of the grip when the camera's on and then try and adjust Av again on the body.
If that doesn't work, and you know something's not quite right about the body's e-dial, then sorry to hear that - it needs to be sent in. I'm of no help with regards to cost, though.

thanks for info.
no grip.

The dial works on the body, and the f-numbers on the lcd display change, but the camera physically does not set the lens aperture correctly.

I'm expecting at least £100 bill for repair.
I'll ship to pentax on monday.

Before you send it in, check out this thread for a possible solution. It is possible a spring may be disconnected.

thanks.

right area. different problem.
the spring looks like it is in the right place. but the slider is not moving freely up and down when the DoF preview is activated.
It does confirm that the spring is on the right side of the protrusion on the slider... I had wondered if it was the wrong side... and had been tempted to flip it over.

ta once again.

Shipped last monday to Pentax (johnsons photopia).
Reurned today.
Replaced aperture control block, strip, test calibrate and clean. £180 inc the vat.
Can't complain at the turnaround, although I did take a proactive line and phone a few times to follow progress.

I had this same problem with my K10D while taking a trip in Utah.

It was around 35 degrees and after a little while shooting the aperture lever stopped functioning. After letting the camera warm up a bit I started getting functionality back up to f5.6, f8, f11. I took about 15 minutes of messing with the DoF preview until it would correctly stop down the lenses up through f16-22.

I've had intermittent problems with the aperture stopping down too far in the past resulting in severely underexposed frames in the past, so I can only assume the motor is on its way out.

Glad it worked out quickly for you.
Now on with the shooting...
