Pentax KM - Prolem with Red Hues
Press the "MENU" button, go to the second item down ("Digital Filter") and make sure it's turned Off. Sounds to me like one of the arty filters has been left on. If none of these suggestions work or you don't understand then ask again. :)

Pentax KM - Prolem with Red Hues
Hefty! - You are a star! The digital filter was set to some weird and wonderful setting. I've just turned it off and it working beautifully! Thanks again to you all for taking the time to post and try to help me :D

Background Correction
Use something like the magnetic lasoo tool to very carefully select the branch and droplets (this might take several goes and try your patience). Then reverse the selection so that everything except the branch is selected, then apply something like the Gaussian blur filter. Doable, but a RPITA :...

Background Correction
How about this? Used the magic wand tool then applied the Gaussian blur filter then adjusted it to this. about 5 mins to do this Regards

SENSOR
It is very unlikely that the sensor will be damaged. A filter, which is in front of the sensor, may be damaged but it is certainly not a user replaceable part. Your camera will need to go to a qualified repair centre to have it fixed. Have you tried wet cleaning products like Eclipse/Eclips...

Shutter Speeds
To take this one step further Emma: Load up your P30 with a fast film (my choice was Fuji 400 ASA for many years) and work on adjusting the Aperture to get the Depth of Focus that you want. Do you want the background sharp, or artistically out of focus? Let the body work out what shutter speed to ...

Dark corner using a cpl
I've noticed whilst using a cpl on the Sigma 18-50 (72mm), that on certain shots the top left-hand corner is slightly darker. Whilst not very extreme, I'm guessing that this is caused by the cpl causing vignetting? I'm using a standard Kenko digital cpl. If this is the case, would a slimmer fi...

Dark corner using a cpl
Wrote some things down before seeing the photos, but that's quite strange. Could it be that it only shows up with photos with a small aperture (high f-number) if so then I've an idea what it might be. :) Probably some dirt on the sensor or on the filter but the later is less likely.

Dark corner using a cpl
I'm quite sure that it is the filter that is in shot since it disappears as you zoom in. Stefan is right in suggesting that it will be more pronounced at small apertures. TBH it is hardly notiecable and easily sorted in PP.

Dark corner using a cpl
Thanks for all your replies and advice, greatly appreciated. I imagine that if this were a dust problem then all images would be affected (been there as well); touch wood, as far as I can see at present the sensor seems clean. What I can now also add is that images taken without the cpl are cl...

Dark corner using a cpl
Glad you found the problem, slim filter would solve it. :) As I specified originally, the triangle is very small, and it has been suggested that it will be easily removed in PP (not sure how, crop perhaps). Oh no you clone it out, just like dolly the sheep :D Most software for photography has sp...

tamron 70-300 and polarising filter
Hi does anyone else have this lens and have difficulty getting it to focus on auto focus with a polarising filter on after about 200mm?

tamron 70-300 and polarising filter
A pol darken around half to a full stop and after 200mm the Tammy is only f/5.6 so it's understandable that the AF struggles. Just be sure to aim at something with a good contrast, you should help the AF quite a lot if you do that.

tamron 70-300 and polarising filter
At least that's the basics behind it Glover, if a Tammy user concur with your findings then that's most probably the cause and not the lens or the AF sensor.

tamron 70-300 and polarising filter
I've got the same problem with the Pentax 75-300 when I attached a CPL. It would not focus at all so I just took it off.

Help
First the easy one and that's the firmware. Hold down the MENU button and power on the camera, you will see the firmware version on your screen. Now the filter, that's quite a problem, one reason to get B+W filters :wink: Since the filter turns you can't get a good grip, so move a rubber band a...
