Professional Sensor Cleaning Advice
Regarding the £35 spent on a 'professional' clean, I must confess that I do agree that it does indeed appear to be £35 wasted. As greynolds999 specifies, who/what are the procedures during a professional clean? The arctic monkey was always an option for a DIY approach, thanks for the recommendati...

Professional Sensor Cleaning Advice
In my K100D there were a couple of stubborn spots on the sensor, could not be blown away. So I bought the cleaning system, and the sensor was spotless after treatment. Trouble now is that I have to buy new fluid (E2) since the Eclipse fluid is not suitable for my K200D. (Check compatibility lis...

tamron mirror lens 500mm
Hi - couple of things: First: it's definitely an f8 lens and incapable of working at f4 (if it was an f4 500mm lens and that small, it would cost an arm and a leg or two!). As posted before I am confused about why your camera is recording any aperture value, unless you are using the Tamron PK-A...

photos coming out blue?
In the morning sun on Wednesday I took some photos with my Pentax k20d + sigma 150-500mm that started coming out with a blue tint/hue to them, this is one of them the exhustive exif data is as follows # Exposure Time (1 / Shutter Speed) = 1/500 second = 0.002 second # Lens F-Number/F-Stop ...

photos coming out blue?
That doesn't just look like a blue 'tint' to me, that just looks like a completely blue photo (and not in a good way ;-)). You've got your white balance set manually, so unless you changed it between the shots that were blue and those that were okay, then that's not the problem, and even tungsten...

Kit lens soft in when held in portrait format
Well, there are three problems here. The first is that most lenses have a curved field of focus (which is why brick walls are a bad test subject, unless you know what you are doing. For this reason, if the centre of the bank is in focus, the edges won't be. Second, most lenses are noticeably sh...

K200D clunking noise
Hello all, I recently acquired a K200 as my first digital SLR camera. When I move it about, ie. turn it on its side for a portrait shot, it makes a heavy clunking noise as if a heavy object is shifting about inside the camera. I would just like to know if this is normal behaviour. Also should it ...

K200D clunking noise
I'm not sure about the K200, but I use a K10d, which makes a light clunk (not heavy, but noticeable) when I rotate it for a portrait format shot - I think this is the internal sensor which lets the camera know that the camera is being used in portrait format, so I guess your K200 has the same (or si...

K200D clunking noise
Cheers Mat, It probably is more of a light than a heavy clunk, I was just getting paranoid in case I bought a dud ! Got the sensor vibrating working too; I've just got to get used to looking through the menu system as it seems it is all there. Regards, Andy.

K200 v K20 viewfinder Accuracy ?
so when a review says the k20 has a 95% viewfinder accuracy ,(what is the k200 accuracy ?) does that mean that 5% is removed equally from top/bottom , sides ? going to try some test shots to determine if theres a fault . thanks, tim. Yes, it means you're seeing the central 95% of what the sensor cap...

K-7 and Paint Shop Pro
I'm having an issue with PSP X2 that when I import a DNG from my K-7 I get black lines to the bottom and right of the image. Is anyone else finding this? It works fine with JPEGs and doesn't get affected by adjusting the sensor so I'm assuming it's down to PSP not being up to date. If anyone ...

Fatal problem or known fault???
I had a similar problem with my K200d earlier this year. Cleaning everything, fresh batteries and a complete 'cold start' seem to have sorted it.:wink: At the moment my problem is the grip showing flat batteries when they're fresh!:shock:

K20D image noise
Just a thought though but you're probable comparing the K20D with your K10D. The K20D use a CMOS sensor and it produce slightly more noise with lower ISO (ASA) then a CCD sensor what the K10D use, at ISO 400+ is the turning point I believe.

K20D image noise
To be honest....that never crossed my mind... But why make the K20D (the flagship) worse than the K10D....??? Weird? Not really weird though, they are both different devices and work in different ways. CCD is an active sensor where CMOS is passive, that's why CMOS is better for longer shutter...

Inspection after sensor cleaning?
A week ago or more I had some heavy dust issues in my K20D. It was not able to eliminate with the build in dust removal shake function through the menu. I spend all afternoon, with the remidies at hand, trying to solve this. I used a brush and airball with marten hair (I think). My magnifier f...

Inspection after sensor cleaning?
The way to do it is use the highest F-number of the lens and overexpose the photos quite a lot. Any dust on the sensor but also the lens will be shown then.
