K10D/K20D firmware compatability
One huge difference between the K10D and K20D cameras that can't be ignored, is the sensor type and size. The K10D has a 10+Mb CCD sensor whilst the K20D enjoys a 14+Mb CMOS sensor. That was a reason for me for not getting a K20D or K7 but the K5 sensor is a game changer. I hope pentax will simpl...

Non flash photography
Is the subject moving or not? If it's static the wider you go the easier it is to hold still and also a wide Diaphragm helps, f/2.8 or even lower. Then heigthen the iso till the shutterspeed is fast enough, better to have grainy photos then moved one. Normally you wont want a shutterspeed lon...

Rubber Comin away on K20D
Well it has to go to Pentax as soon as I can decide to part with it go so they can take a look at my sensor. I will let them wrestle with it .. from what I have read here lately of the Pentax service centre I doubt they would even realise it was me.

Ned Bunnell Blog
I read his blog with interest. The claim that Pentax would need to design an entire new lens range for a FF camera, just does not seem to sit right. Has anyone else noticed that many of the latest lenses are reported to show no sign on vignetting on 35mm film cameras? Was a redesign for a la...

Ned Bunnell Blog
I read his blog 5with interest. The claim that Pentax would need to design an entire new lens range for a FF camera, just does not seem to sit right. Why not? Many DA Lenses will vignette on a 135 sensor, and many FA and earlier lenses do not have a sufficiently parallel light path. Has anyone e...

Should I go for the GX10?
Just to put a spanner in the works, Samsung GX-10 at Park - £319, Pentax K200D at LCE - £249. Hmmmm. The Samsung has twin dials, and is in effect a K10D in drag. The Pentax only takes AA batteries, yet has the K20D Menus for colour control (which are far better than the K10D) Both have the s...

Can You all Check your K20D's Please
No problem with either of mine but I would not leap up and down about it if the problem had arisen. The sensor failure on my P & S Canon was far more alarming.

K20 dust alert system
Hi all i just wondered what everyone thought about the k20 dust alert system. Where the camera takes a jpeg of the sensor. How accurate is it ? I find myself using this system after every lens change after purchasing the DA's 16-45mm and 55-300mm last week and have changed lenses a few times. ...

K20 dust alert system
No need to keep doing it after each change I myself never used it, the only thing I have set is at start up, when you switch the camera on it shakes the sensor:wink::lol:

K20 dust alert system
That's dust removal tel, not dust mapping. Ok Ta!:oops: Never done dust mapping as never had dust on the sensor:P

K20 dust alert system
for me the sensor shake seems to work perfectly. After allmost a year there is still no dust on the sensor. On the other hand, I only cleaned my DS two times with a Arctic Butterfly, I never had stubborn dirt on that one and since the K20D has a coated filter it will stay clean for a lot longer. ...

I agree Golf, they cannot do these half hearted. going away from the AF and movie mode a bit, with all these rumour going around the web about the K-7, do you get the impression that this camera is the one that Pentax wanted to replace the K10D? Just a hunch, as if everything is to be believed, t...

The problem with AF is how it works, here is an drawing and you will see what the problem is. Yep the mirror let's some light through and reflects it on to the AF sensor, this means that the sensor needs. So to get the AF to work with video you will need a completly other system, that's where...

Well no since the cmos sensor doesn't have anything to equipment to focus with, it only record light. If you autofocus with Liveview the screen goes black I think and now you know why it does it, sony use a different system. This the sony system, when the line is vertical it will go through ...

The new camera is likely to have "contrast detect" AF off the sensor. Some beta tester say the video capabilities will "snuff" the Nikon and Canon DSLR video capabilities.

Battery indicator with more than 2 segments gives a little more accuracy. ISO indicator AND exposure counter in the top LCD, allso an improvement. The black&white image of the TOP LCD allso shows a small mark printed for the location of the sensor.

New kit lens. WR = Weather Resitance???? If so I'm tempted to buy one, would be a great adventure lens if it's cheap. I don't see why it shouldn't be autofocus in movie mode. There are rumours of a Nikon D750 coming out with that functionality and there are surely various possible technica...

what if that really long flat prism is made that way because the af uses a hybrid of safox and moving the sensor forward and backward...which would make all mf lenses af, make all older af lenses focus faster, AND allow af in video mode? of course the video would need distance info from the lens its...

What's the difference?
My understanding was that there was an extended dynamic range function, which just boosted shadow or highlight detail captured by the sensor. Not sure whether this works at the capture stage or the processing of the RAW image. There is an 'HDR filter' as well but this seems to be just a visual ef...
