Should I be concerned?
As soon as I mentioned the string of pearls sensor stain to the dealer, with K5 and receipt in hand, they swapped it over there and then without any bother. I was back out of the store with replacement in hand less than 5 minutes later. Acknowledged and rectified immediately (as it ought to have be...

The Camera from hell
I though I had gotten off scott free because my K-5 always worked perfectly from day one, no sensor stains, focusing issues etc. Then the Tamron 17-50 F/2.8 lens I bought along with it broke. :P It's like something bad just had to happen becauase it wouldn't be fair on all the other K-5 users otherw...

Fungus attack.
I've had a disaster and I'm looking for advice. For various family reasons that are unimportant in this context I've not had access to my lenses (apart from the two I use as 'walkabouts') for more than two years. I finally got to the two drawers they were stored in today and there is mould and fungu...

Fungus attack.
You can probably save the M 50mm yourself, assuming the f1.4 is anything like the f1.7 and f2 versions. I managed to clean similar fungus from a couple of cheap ebay finds which has yet to reappear after a year or so, and they seem fine optically. I found plain vinegar on a cotton bud worked well...

Fungus attack.
OK, thanks for the responses. My lenses were in soft cases, which I think helped to collect the damp. Probably they should have had silica gel in, but that's the way I've been keeping them for years, previously, though, I'd have had them out every month or two to check them, and in any case the two ...

Fungus attack.
Professional cleaning: Storage: Screw-cap or snap-lock tupperware containers lined with adhesive-backed Fab Foam with discs made of the same in the base and lid to provide cushioning and prevent 'rattling'. Lenses stored in the presence of self-indicating silica-gel having first ensured they ar...

Dead K5 ... Help.
Sorry no advice - just an observation I bought a Kr 6 months ago just to keep me going until I could afford a K5 intending to then sell the K20D and keep the Kr as a back-up for the K5. The Kr has not caused me any sleepless nights - has been a fantastic performer since day 1 - has already tak...

Dead K5 ... Help.
When you look how many here have a K5 and how many here have a problem (minus the sensor stains) the K5 is not doing too bad. The Kr have problem with the scroll wheels, is down to the grease that is being used. Good thing is if that fails they fail early in their life time so well inside the gu...

Dead K5 ... Help.
My K-5 has never given me any problems to speak of (other than a dirty sensor which was largely my fault and cleaned up as good as new anyway). It's my Tamron 17-50 lens that died on me. :P Sent it off 10 days ago and currently awaiting a replacement. Surely if Amazon give you a full refund you s...

Try sensor cleaning mode to see if the shutter opens fully.

K-5 and annoying smears
I would assume that your sensor has dust on it. You can perform a dust verification test available through the k5 menu. Quite strait forward. Some sensors from the k5 have had problems with markings that i am aware of, but this has probably occurred during lens changing in dusty conditions. I would...

K-5 and annoying smears
I am not sure how accurate the system works but after seeing your photo there is no doubt that there is dust on your image. I wouldn't rely too much on the dust cleaning on start up. Get that boy into the store for a clean. If you need any advice on doing it yourself let me know. Good luck

K-5 and annoying smears
The 'smears' are almost certainly caused by dust, tiny little fibres of it by the look of it. Have cured similar with the rocket blower, although it's best to be very careful with the rocket blower as you can get the dust all over the place, up into the viewfinder etc. I agree with what you say. For...

Annoying dots on pictures
On some pictures noticed that sometimes appears some circle shaped "shadows". Couldn't find a reason for this - checked lenses (sms 18-55 dal almost like new, tamron 70-300 bought less than month ago), checked sensor but can't see anything - everything seems to be clear. Dots can be easily removed...

Annoying dots on pictures
Grzegorz, you have specks of dust/dirt on your sensor. Nothing to worry about. This happens alot when we change lenses and dust comes inside the camera. Buy yourself a "rocket cleaner pump" (a little blower pump, shaped like a rocket) and you should be able to get rid of the dust from the sensor. If...

Annoying dots on pictures
Probably the best dry cleaning system available is the Arctic Butterfly from Visible Dust. A Rocket blower will, as others have said, simply move the dust to somewhere else in the camera. It's not likely to remove it. The Arctic Butterfly relies on a small electrostaic charge on its nylon brus...
