Sensor Cleaning Service!
After seeing ChrisA's post I'm looking at the Eclipse E2 stuff. What swab/wipe should I be using? Some of them seem to be around £25 for a pack of 10... I used the on the CameraClean web site. (and it was only £100+ cos I bought an Arctic Butterfly first :()

Sensor Cleaning Service!
so is the moral of this thread,clean lightly and clean regularly ? There is no single answer to this question that will suit everybody except perhaps, clean the sensor when it needs it. Even then, one person's needs will be different to others. There are so many variables affecting how dirty a sen...

Med Format. DSLR
For amateur purposes, I don't see the point. For professional purposes, you'd just buy the Hasselblad. Pentax wouldn't sell to professionals because they don't have a professional service setup (they could if they wanted to but plainly they don't find it worth while, ditto Olympus). The professi...

Med Format. DSLR
I can see that a MF pentax can be atractive for starting professionals though and even some oldies might go back to Pentax simply for the joy. About the sensor, it's going to be most likely a Kodak, the with 31,6MP was last mentioned but Kodak in the mean time have brought out the & with 39...

K20D status now end of life
I have been looking at other camera manufacturers lately and am gobsmacked by the fact that Pentax is the only one with SR built into the camera. Others may follow suit but Pentax was the first. Hi Paul, I think you will find the both Pentax and Olympus introduced in body image stabilisation at pret...

K20D status now end of life
Hi Paul, I think you will find the both Pentax and Olympus introduced in body image stabilisation at pretty much the same time with their D-SLRs the K10D and E-510 :wink: Ooops, ok I should say I was really referring to Nikon & Canon. I have absolutely no experience of Olympus DSLR's. Only Olympus I...

K20D status now end of life
Personally, I think its a sad indictment of modern times that such a superb camera as the K20D has had a production life of only 18 months. Compare that to the older film cameras (K1000, ME, MX etc.) and it is disgraceful, I think. I agree , but like or not the K20 is seen as old technology. I doubt...

K20D status now end of life
With the K-m, that is only several months, a lot less than 12, and in fact the normally biased photo press (ie CaNikon press) really rate the K-m as probably the best entry level DSLR out there, until the recent EOS500D and Nikon D5000/D3000 appeared. Well this is possibly the answer why the K-m ma...

K200D replacement
I was aware of the K-M but thinking more of a current model. Pentax are weird here in that they allow a model to disappear without any replacement.I had a K200D, sold it and regret it. I still believe that Pentax have the finest lenses with the likes of the 16-45 which gives 24mm to 67mm in old mone...

Comparison between k200d and k20 in terms of noise
The K200D sensor is the same as the K10D, a CCD 10.2Mp sensor. In the K20D, Pentax changed to a CMOS construction 14.6Mp sensor which has a much lower operating temperature. CCD sensors can be prone to overheating during heavy use, like indoor sports events, and excessive noise can become an issu...

AP K-7 Review
If Pentax can't market their cameras properly that's down to them. It's not any magazine's job to do it for them. Hmm yes there is something lacking in Pentax's marketing. And it's not all down to money - in Digital SLR Photography magazine, they had a two page spread advertising feature (cunningly ...

infrared filter
Your K20d has an IR blocking filter in front of the sensor. You can take IR shots but you will need MUCH longer exposures. Best thing is to keep experimenting!

infrared filter
All digital cameras are very sensitive to IR so the manufacturers put a filter in front of the sensor to remove some or all of the IR. It can cause colour shifts and loss of contrast. The *istDS is not too bad in this respect and will work quite well with IR, but the K10D filtered quite aggressiv...

So how long exposure are we talking about. I don't understand this bit about an IR blocking filer in front of the sensor though. Generally, internal reflections within a lens can cause flare and loss of contrast. Because the sensor is sensitive to IR light any IR that is being scattered will affect...

K20 sensor clean on start up
I have had this function turned on since I got the camera. Have read in another post; "some people think this is not a good idea". Could "some people" explain further:?: Davex.

K20 sensor clean on start up
Personally I do not use this function. Shaking the sensor inevitably puts some stress on the mounts and other parts of the camera so doing this unnecessarily may result in a premature failure.
