You can also get them on Amazon as low as $25-26 Worth considering against the UK prices Paul

The thought of using the cheapest swab available in the delicate internals of your camera makes me cringe. Will an Arctic Butterfly not do the job? They are a lot safer.

I wasnt advocating using a cheap product. Merely providing a possible link to an alternative, and Opteka are a very good brand. Paul

As long as it's not an oily deposit,the butterfly should do the trick!

Thanks guys I have thought about the butterfly before it does seem less invasive than other forms of sensor cleaning tools. I found the swabs very easy to use although I was a bit concernd if I was putting to much preasure on the sensor while cleaning, but a very stubborn bit of dust came off a tre...

I've used the wet swabs with success. Can't remember how much I paid for them. I got hem of ebay over a year ago. I think they were about £15 for a set of 15 swabs and a small pot of fluid. I haven't cleaned my sensor for months now, although now I've two bodies I don't change lenses so often. Al...

I've used the wet swabs with success. Me too. Got them from . Not cheap, but it shifted a lot of horrible oily particles that the Arctic Butterfly didn't touch.

ChrisA wrote Me too. Got them from cameraclean.co.uk. This family-run business also trades under the name of 'Just' and is located less than 10 miles from where I live. They also sell pre-wetted swabs which, depending on the size of sensor to be cleaned, can cost up to £37.00 for 12. Whilst this ...

Newer sensors worse results? (open letter)
I would like to see some DOF test at large aperture, the same light condition, same lens, and i.e. K5 and K100 or K10 (K5 where its sensor photocells are much smaller than of K100 sensor). Would the suggested bigger loss of "marginal" light affect DOF in a visible way or not?, or in other words is ...

Quick test on a K20D indicates that Pentax haven't adjusted anything and the 'A' 50mm f/1.4 lens underexposes at f/1.4 by about 2/3 stop. Seems OK at f/2.0 This is using Av program. After further tests the underexposure seems to vary between 1/3 and 2/3 stop. I carried out the same test with m...

It should also show up on a sequence of shots taken in Av mode starting wide open and then closing down in 1/3rd or 1/2 stops and letting the camera set a new speed each time. Every shot should be about 118R 118G 118B. If it is being compensated the first 3 or 4 should be different. I'd have to try ...

It's stated somewhere on the web Stefan exactly what K value Pentax set their meters to. As a follower of Ansel Adams Zone System in my film days I never bother about K values and just stick to 18% Grey which is RGB 118 and then work from there. The digital cameras don't seem to work too accurately ...

These lenses are not letting in less light than they should, the problem is that the meters can't cope with them in some circumstances. So the metering is what is out, not the lens. The details of how and why this happens are in the literature somewhere, but it's a long time since I read the appr...

Newer sensors worse results? (open letter)
i follow what's going on, but i'm still intrigued by this statement from mark dubovoy over at ll In fact, is not even clear that large aperture lenses will deliver a shallower depth of field as intended. The DxO measurements to date prove that the marginal light rays just don’t hit the sensor. Th...

the depth of field effects are significant, in my opinion. so what's going on there? perhaps out of focus areas strike the film plane more perpendicularly than in focus areas? i'm no optical engineer, so i can't explain. Isn't that the opposite of what he's saying? Marginal light rays being less per...

Isn't that the opposite of what he's saying? Marginal light rays being less perpendicular, they are simply not picked up by the sensor and therefore don't contribute to exposure or the softness and size of out of focus blur. However if this was the case in practice surely people would have notice...
