Cleaning K10D sensor
OK, I'm jumping the gun on this as I do not yet have a dust problem. The dust removal system and/or a quick shot with the rocket blower has been working just fine for now. But it has only been a week... If/when the dust goes beyond these methods, would it be safe to use the same sensor cleaning ...

Cleaning K10D sensor
My DS has been in use now for 15 months and thousands of exposures. I've never had any dust problems (and yes, I do change lenses!). I dont leave it lying around without a lens or body cap and I make a point of switching it off before removing the lens (I believe the sensor is charged and is capable...

Cleaning K10D sensor
Yeah, and if you use prime lenses I suspect you'll have a lot less problems. I know of people who say they clean their sensors every week or so with swabs and solution. I've only had to clean mine in the istD about three times in the past year and a half. So I do suspect even less of a problem ...

I would have thought that Pentax were involved in an attempt to get acess to a supply of sensors from a maker other than Sony,......Samsung are one of the few makers of sensors. I have been trying to find out on the web who the makers of the pentax sesor actualy are. It has been assumed by num...

Phil Askey's review of the K10D suggests the sensor may not be manufactured by Sony: "Interestingly this CCD has slightly different specifications than the Sony unit used in a few other ten megapixel digital SLR's so we can't be sure of its origins. It's 23.5 x 15.7 mm with 10.75 million tot...

K10D Stop down metering exposure problem
Thanks for the replies to my posting, there are however a few points Iwould like to point out. As I understand the point of having an A setting on the A-type lens is that it is possible, provided there is some kind of predictability in the relationship between the aperture actuator and the actual a...

London Shots - K10D vs 120
A few weeks back I posted some of my first K10D shots from a trip into London - finally got round to posting the film efforts last week and got them back from processing today. What's interesting is that I can show you some comparision shots of the K10D vs 120 - decide for yourself if it's a fair...

K10 manual metering question.
viewfinder, sorry if my reply seemed patronising, I think I understand what your problem is now. The cameras meter takes a reading of the light coming through the lens and assigns a shutter speed accordingly. Since we have an open aperture metering system, this light does not correspond to the am...

Buying Advice!
Hello all, I am trying to decide between a K100D or the K10D. I will be shooting indoors mostly with no flash. I have heard that they have the same sensor and that the K100D would take sharper shots.

they certainly do not have the same sensor, the K100D shares it's 6 megapixel sensor with the older *ist line while the K10D has an all new 10.2 megapixel sensor. The 10D is a generally more upmarket semi-pro model, it is fully capable of producing professional level results in the right hands an...

Buying Advice!
I keep getting different answers. I was in another forum and was told the K100D and K10D have the same size sensor and that the K100 the K100D is probably better in low light due to its smaller, less noisy sensor and that the 10D crams 4 million more pixels into the same area of the chip, making the...

Long exposure = long delay
The 'delay' is due to the noise reduction system. Turn it off in the menu and you get a much noisier image displayed faster. Suggestion: leave it on. The camera takes a second exposure, pure black except for sensor noise. It then does some clever electronic wizardry to subtract the noise in the s...

infra red conversion of istD
Hi Denise and welcome to the board! There have been a couple of threads about this that I know of: https://www.pentaxuser.com/forum/viewtopic.php?t=2557 and earlier: https://www.pentaxuser.com/forum/viewtopic.php?t=1544 Several of us have had a dabble with it, with some good results...

*ist-D in Action
Just been doing a spot of spring cleaning of files and dumping lots of the junk photos that I've accumulated. Stumbled across this one which I thought I'd share with you... Taken at Willen Lake in Milton Keynes last Sept with *ist-D and Sigma 70-200 f/2.8 EX. Was about the only shot I nailed out ...

Pentax FF future made clear
Guys, After many years of speculation, Pentax has finally made it's intentions clear regarding full frame. Pentax has just announced that the new 200mm, 300mm prime lenses will be DA* lenses (APS coverage) rather than the originally announced D-FA (FF coverage). This now locks them into ...

Pentax FF future made clear
There is some rumour on dpreview that DA lenses would support a 1.3 sensor. Other people are mentioning that lenses like the DA70mm are already cutting it a bit fine for coverage at the edges on a 1.5 sensor. I think the DA lenses will have varying degree of coverage but the unification to a DA s...

Interesting that the 645D now sports a 31.6MP sensor from Kodak. This will be a killer camera. providing the cost is sub-stratospheric. G

Testing the K10D
Well I'm back from Kenya and have tried the K10D for the 1st time in anger :D The image stabilisation worked a treat allowing me to take photos at 2x -3xlower ISO ratings than I'm used to. (500mm at 1/200 is fine even on the back of a Safari bus with the engine still running) Every time I ch...
