Messed-up clearing viewfinder
Usually it should be just a quick dust with a dry microfibre cloth/tissue or a blow with the Rocket Blower - it should not need more than this. Yeah I agree with all of the above , I made a little tool out of a paper clip and it was a piece of cake to remove and change the focus screen. But the s...

Messed-up clearing viewfinder
These focussing screens are made of a plastic material and should never be cleaned with any solvent, including sensor cleaning fluid which is mostly methanol. I've never had the need to clean a screen from a DSLR, but in the past, I've had to for film cameras. I washed them in warm soapy water, d...

Stiff e-dial in cold
Those links seems to handle cases where dial wheel selections jumps or behave more a less accurately, but not stiffy dial wheel. I believe on those cases lubricant cause bad contact, insulation between contacts. On my case lubricant might be too dry or too solid. Some component from lubricant ...

Long exposure / light photography (painting)
I'm very new to Photography but have read a little about this. I have taken a few traffic Trails which i think have turned out well. I also have a K-x. I would recommend getting an IR remote shutter release as this allows you to go past the 30 sec mark and use Bulb Mode. With the remote you can ...

Fitting old lenses on DSLR
Check the M42 to K-mount adaptor. If it is the type that fits entirely inside the K-mount on the camera (i.e. the camera body is flush with the back of the lens) then it should focus as normal. If it is the type that has a wide flange that sits against the back of the lens and makes the lens sit s...

More K5 help please
Irfanview is good for viewing the photos but I wouldn't convert them in it. Try RAWTherapee for a free converter. If you are going to be shooting in RAW all the time though I recommend you buy a converter. Have a look at Capture One and Bibble if you don't want to go the Adobe route. Thank you Gw...

Pentax FA 50mm f1.4
The middle shot shows that the lens can focus fine. There are times when the AF locks onto the wrong thing. If you are not already doing so, I find that setting the AF to the 'centre of viewfinder' position helps, so in in effect you are then selecting the point of focus yourself which is normally w...

remote control
The remote is not the problem - the Kr just doesn't have a sensor at the back. I have had a remote control F since I had the Ds and it still works just fine. Cheap remotes can give problems. If you want a wired remote then some that are suitable for Canon are also good for Pentax and are cheape...

remote control
There shouldn't be any problems with IR releases. Some settings are needed in the camera and the red light should be flashing. Some of the cheaper remotes have poor battery contacts or very cheap batteries that don't work too good. The remote also has to be pointed directly at the sensor. I...

K200 shake reduction
I can't tell whether the shake reduction is working, test shots are inconclusive, I can't hear any motor noise. What is the best way to check ? You can check with a timed exposure and no lens/body cap on the camera, you should be able to see the sensor move when looking into the lens mount throa...

K200 shake reduction
John, Thanks. I've tried with S.R. turned on and turned off. At both settings ( on bulb ) I can hear a faint noise, abit like a geiger counter, but it seems to much less if the camers is on a firm base. Though with the current gale blowing there is still probably a bit of shake on the dining ta...

K200 shake reduction
Hi David, I'm not sure SR works in B (bulb) as you would generally have the camera tripod mounted. I apologise for using the term "timed exposure" I was thinking in the region of 1-2 seconds on the shutter speed, you should see some sensor shift if you move the camera. John

K200 shake reduction
Johnwhit Well spotted, I tried it on Manual, occasionally there is pronounced movement of the sensor, but usually nothing. John Riley I'll try that, the last time I tried to do a comparison it was inconclusive, but no harm in a more structured repeat. I only joined the forum this week, well plea...

K10D focus problems
Gartmore, I have made the hack. Then I had the problem of huge deviations for different focal lengths. I don't believe its any of that because my camera has had its failed focus and not so sharp images before. Not like these though. When, as evidenced by the shot of the horses with the stone i...

K5 - Electronic Level Adjustment??
Chris, Thanks for the further info - I hadn't picked up that other K5 owners were getting this problem. It all sounds very depressing. My sensor is much further out than yours, I'm afraid to say. I really can't understand either why there is no calibration function. I don't know of any instru...

K5 - Electronic Level Adjustment??
Update on my K5 - Spoke to SRS and though a swap for a new camera is an option they recommended getting the sensor adjusted as a new camera could be just as out of adjustment as my current one. Everything else is fine on my K5 so I am going for this. If I see any sign of it going out of adj...

K5 - Electronic Level Adjustment??
Take it there's no way of user adjusting level on a K10? I bought it second hand a while back and it always seems to have had the sensor misaligned slightly, so horizon, buildings etc are contantly slightly off line. Any recommended apps for adjusting pics etc? Thanks in advance, very frust...

Dust
Dust on the lens only very rarely becomes apparent on the image. Are the dust specks in the same place on every image? Are they a lot more apparent at small apertures than large ones? If so, it's on the sensor, not the lens. You have three choices: - Blower (just tends to move dust arou...
