Faulty lens or ...?
OK, I can see the part that concerns you. If this 'artifact' is due to the sensor, it's almost certainly one of only two causes. 1: sensor dust, pollen, etc. 2: sensor stain Sensor contamination, or 'dust bunnies' as they are sometimes affectionately known, can easily be eliminated by corr...

Faulty lens or ...?
Well done ChrisA, I can see it now . I'd say dust on the sensor janusz ,do whatChrisA and Mannesty suggests to check,but don't worry just clone it out. Maybe when you get a little more have it cleaned or buy some kit and do it your self it's not dificult and there is lot of advice on this site on th...

Faulty lens or ...?
A sensor stain requires it to be fixed by Pentax or their repair agent. Of the several dozen pictures I've seen of the sensor stain problem, none looks remotely like this. No reason for alarm there.

Faulty lens or ...?
Well I've just got back in and see there have been no updates to this thread. I'll try to suggest why the D90 pictures may look better than those of the K-5 to the OP. While one would need to use the same lens on both cameras and the photos taken at about the same time for a true comparison (give...

Sensor Marks - Not
Opened a host of photos on my Laptop, and Oh No, I thought more marks on my sensor. Just needed a wipe of my screen. Haha.

LCD screen protectors
I always use the GGS Glass screen protectors, they seem to make the screen clearer under some conditions, I personally like the idea, when the camera is covered in dust, sand and sometimes mud, you know the screen is OK. I have tried cleaning an unprotected screen covered in sand and it did get s...

KR Lens...
Oh ok, how come it won't be wide angle? sorry if I am just being a little thick... Due to the smaller sensor size, 28mm on APSc will give a field of view similar to 42mm on full frame. And 42mm on full frame is not considered wide angle. On full frame, 35mm is considered the beginning of wide ...

Replacement for K10D
Personally I would ignore the K100D as it is in reality only a rebodied DS but with a pentamirror and shake reduction. On your limited budget I would either go for:- Another K10D. You already have one and it will be natural or K20D. Same body, same battery, same grip, same buttons and me...

Remote Controlling your camera HELP
is a page full of reviews of camera traps. They aren't cheap. An IR remote needs filed of sight of the camera to work. Depending on the model camera you have sensors front and rear or rear only. The range of the IR remote varies depending on the model. The Pentax remote F has a working distance o...

50-200 V 18-135
Sory am unable to figure out how to post the pictures Advice on that here: You can get the basic exposure details of each shot from the camera - helpful if you could show this at the very least as if for instance the 18-135 lens was wide open and the 50-200 was stopped down, that would affect s...

Bi-Latrel Pricing....
I too had a poor time with the D7000 (Sensor grease thrown from a badly lubed shutter mechanism) and sundry other problems that Nikon wouldn't admit too at the time! I found the handling sub par being a Nikon user/Fanboy for 25+ Years and having owned pretty much everything they'd produced, it was ...

catch in focus
Was the focus sensor in use still aimed at the chair?

There's usually no need for any compensation when shooting with a K-5 in RAW as the sensor is capable of recording a very wide dynamic range. During post-processing you can recover a massive amount of shadow detail. The main objective is not to 'burn out' any highlights as these are not recoverabl...

Skies, and in particular low sun situations, have a large dynamic range and you'll have to perform some post processing if you want to get detail in the sky as well as light in the shadows. With highlight and shadow correction on you're still not going to cover the range with an 'out of the tin' JP...

Whilst I agree that most of the image processing functions (eg white balance, sharpness, distortion) are applied to the JPEG file only, I think that highlight correction and probably shadow correction are applied at sensor level and thus affect the RAW file output too. The fact that enabling highli...

All I can say is the camera manual states on page 202 RAW format is a CMOS sensor output format saved without processing. If Pentax don't tell us the whole story ........... John

Probably splitting hairs, but the truly raw output from the sensor has to be processed somewhat to decipher the information and present it as a demosaiced colour image. There is, so to speak, a bare minimum that has to be done regardless. However, there is no application of colour temperatures, s...

RAW format is a CMOS sensor output format saved without processing. That may be correct. Perhaps dynamic range correction is applied at the sensor level, prior to the data being read? Please don't ask me how, that's way beyond my brain grade. If you've got time to waste test it for yourself....
