For sale used Pentax k-5 with a lens and other stuff like box, cables, charger, 2 original Pentax batteries, manual, strap.

Looking for 300 for all the stuff.

Shutter count is less than 17 000. Everything works BUT there are few PROBLEMS:
1. There's a bit of dust particles under the screen
2. The lens produces a circle artifact on images as you can see on the sky picture in the top right corner
3. The most important problem is that the selected programs don't work properly if not in "live view" mode. (In "Live view" mode everything works fine) For example if I select Av, the shutter speed value is never selected properly. It always is the smallest possible value of 1/8000 s. I've used the camera in full manual mode (M) so it wasn't much of a problem for me.

Let me know if you have any questions.

Does the lens produce the artifact at all focal lengths and is the artifact always in the same place? It looks a bit like a dust spot on the sensor from the image you have posted and if so, with care, can be dealt with!

Yes, it's always in the same place but its size changes a bit with the focal length change.

And the size and darkness will change as the aperture changes? I still think it is a dust spot on the sensor and not the lens being at fault.

Just done some tests. Indeed it looks like the darkness and the size of the spot changes with the aperture. With high number like f16 it's darker and smaller than with f4.

It is a sensor dust spot then!

People might be interested to know whether this is a problem only when using the 18-135, or if it applies to other lenses also.

It applies to all lenses I've tried.

It is probably a daft question, but have you tried resetting to factory settings

Yes, I've tried that. Also I've updated the firmware but nothing helped.
