K-5 horizontal alignment issues
I fear my K-5 will have to be returned to SRS. Whilst on holiday to Cornwall, it has developed a severe horizontal mis-alignment, i.e. in the viewfinder the image is perfectly straight, but when viewing the image taken it is sloping down to the left by a significant amount. I think the sensor has ...

K-5 horizontal alignment issues
Not really helpfull but how does the electronic level read? just wondering if thats out of kilter also. The level has gone miles out too, I think the level reading is linked to the sensor, so both will go out of alignment at the same time. Regards David

K-5 horizontal alignment issues
the level reading is linked to the sensor, so both will go out of alignment at the same time. Worth verifying what happens if you switch off horizon correction for exactly this reason.

PU Gallery exif data
I'm not sure but I think this is a factor of a cropped sensor. The F number doesn't change as it's the relationship between the focal length and the aperture size. In a cropped sensor camera the F number stays the same but as the lens is effectively increased then the Aperture Value is, in eff...

K5 noise.
Hi Major, this has come up one or two times before so it might be worth checking through the forum search; but from memory, as the sensor assembly in the camera is, to an extent, floating (so that the shake reduction will work) it's movement is what you hear I think; or else it's a portrait/landscap...

K5 noise.
It is I think mentioned in the instruction book, but is easily missed. It is the sensor assembly moving, as it has to for the SR system to work.

K5 noise.
The sensor on the SR system is held in its place using magnets. Same magnets are used for movements of sensor when SR is on. So swiching off SR just prevents the movements of sensor but those magnets are still in use keeping the sensor middle of the area and stationary, and this is the noise you hea...

Do you have a k-r with an AA adapter?
Hi Peter, The camera is virtually unusable at the moment - the batteries are inserted correctly and the camera is set on Battery type auto. The mirror keeps jamming up, continually 'flipping' or sticking so I end up with either a long exposure when I've chosen a fast 'shutter speed' or not takin...

K5 - diagonal ripples in background of image! Fault?
You haven't by any chance attempted to clean your image sensor, have you? If your lens is clean (always clean in a circular motion with a lint-free cloth, or lens tissues), then the next "obvious" place is the sensor. If that's not it, then it's something to do with the internal workings, and I'd ad...

K5 - diagonal ripples in background of image! Fault?
Thanks, Steven. Haven't touched the sensor or attempted to clean anything. Brand new camera has had little use really. This effect occurs even at fast shutter speeds so I've ruled out shake. I guess it's a fault then. It's under guarantee. Ian

Could someone give me some advice please.
Hi Charlotte In fairness to Amazon, they have reacted in a much more positive way than many retailers I have dealt with. However, they are spinning SOGA in their favor and are being very selective with what they are quoting. There are really 2 possible arguments here: 1. A known inherent...

Could someone give me some advice please.
It's all a bit wooly really, but don't forget that after six months the onus is on the consumer to prove that there was a defect from new. This might be possible with, say, the sensor stain issue. Lots of corroboration could be printed off from the internet. With some other faults it could be wel...

Bad cast (pentax ist DL)
Thanks for that reply Steven, but the photo is not important, i was on holiday up yorkshire last week when this started so the photo was just taken as a example of the cast, no doubt some kind of sensor has given up, maybe its time to upgrade as i bet repairs will be out balanced against a new one

live view
It does this to perform the autofocus in both 'face detection' & 'contrast af' modes. The only way to avoid this is if you set the Liveview for 'phase difference' mode....the live view momentarily switches off and the camera autofocuses with the AF sensor and doesn't zoom in. Go to MENU > rec.mode4...

Lens design
Use black card from a craft shop to make a prototype. You may find that a standard food tin will be about the right size and shape, so make your prototype that shape and size (about 74mm diameter by 105mm high) The lens focussed at infinity and set to the minimum aperture will show up any vignetting...

Removing PF with Elements 10 or LR3
MattMatic - too much PF in my shots, and too little patience I'm afraid. Get a better lens? :P PF is a function of lens & sensor, and often a function of aperture too. (My DA*16-50 suffers from transverse CA at apertures wider than f/4) I'm really looking for a silver (purple) bullet solution that...

Issues with DA* 16-50
I discovered something rather unstartling when I came back home to review my photos (it was too bright outside, so I couldn't spot it on the screen). This is a cutout from the 1.1 square (3x3 grid) of my image. What is it? My thought is that it is something that have gotten inside the le...
