K5 Shutter Jamming
I hope this isn't a stupid question, but does the K-5 ( and for that matter the K-20D and K10D, etc ) actually have a mechanical shutter? When I change lenses I can see the sensor behind the mirror. Is there any need for a mechanical shutter with a DSLR? I cannot see how that is possible... if the m...

K100D focus screen

Dust on ,my focus screen
You don't use an Arctic Butterfly on focusing screens and mirrors. I have found holding the camera facing downwards spots in the viewfinder system can be removed easily with a rocket blower. As regards the sensor, the built in dust removal system works most of the time and a rocket blower the res...

Dust on ,my focus screen
The mirror is already treated by the manufacturer How do you know? I know the filter on the sensor has an anti-static coating but never heard something about the mirror.

Viewfinder puzzled newbie
It sounds like you have some dust somewhere, the sensor of my K5 was very dirty when I received it but has cleaned up OK.

Viewfinder puzzled newbie
It's not dust on he sensor, it's hard to describe what i mean. Think I need to find a shop close by that sells K-5's and have a look through their viewfinder to see if it's the same.

Viewfinder puzzled newbie
No I didn't mean dust on your sensor I meant on your viewfinder, screen or mirror Richard.

Kx and Tamron SP 70-210 compatibility
It looks like your ka adapter isn't quite working. You should have the aperture appearing in the viewfinder. (Presuming the lens is set to the A setting or whatever the equivalent is!) Try cleaning the contacts, if that doesn't help, disengage the lens in the mount, and then very slowly turn it back...

K-5 Silver... Crashed
Mmm, is this another issue with the K5, Perhaps my decision to hold off for another couple of months is justified? We had sensor stain, then af under tungsten light, and now this, such a pity for a camera that should be sweeping the board. Davex.

what do you think stain??
If it's an inherent manufacturing defect, it should be covered for up to 6 years under European law. I think Pentax are going to be replacing these for years to come. Is it really Pentax's fault though, or Sony's, the sensor manufacturer? Are there other cameras using the same sensor from o...

what do you think stain??
Whatever the contamination is, it seems to be invisible to begin with but causes a gradual failure of the adhesive between the filter and the sensor, creating those little 'bubbles'.

Never heard of the problem with the K-r and your photo looks like just a dirty sensor. Should clean off easily if that's the case. Any that you have taken with the problem can usually be removed when editing.
