Where can I get an OEM K-m focussing screen?
Cheers I did a good job on mine - really messed it up:shock: May stick with it, see what a local shop comes back with. Its annoying but there seems to be no effect on the picture.

Where can I get an OEM K-m focussing screen?
There won't be - the sensor doesn't look through the screen. In an SLR the image from the lens is reflected up onto the focusing screen by the mirror, this flips up out of the way when you take a photo. For the same reason I won't be too worried about a minute dust speck when I swap mine back, altho...

Where can I get an OEM K-m focussing screen?
I do not see any exposure problems, and also focus seems fine. But I must admit that I have not done any very precise tests on focus. The screen does come with shims, in case needed.

No need for any shims? And exposure not affected? I believe it affects the centre focus point though, as long as you use centre average it would give good results from what I hear, it's with the spot metering it can go wrong.

I had spot metering and I would get wrong reading with slower lenses. Since then I have used centre av...

I got my OEM K-x screen from They don't list one specifically for the K-m but as the K-x has the same body (and I suspect shares a few components in common) I thought it'd be a safe bet.

Where can I get an OEM K-m focussing screen?
I've tried the Chinese made 'Travor' horizontal split prism version, and spot metering is badly affected. As I use spot metering frequently this is a nuisance. The quality of the screen is also not ideal - but then you get what you pay for! I ended up putting the original screen back in for...

My main complaint is that the cheap split prism makes the image too dark, especially if you want to use a polarising filter or similar. I would have changed back if I hadn't managed to scratch the original screen, now waiting for a replacement.

Pentax K-x Digital Camera
After playing around with the focus points on a K200D, I did put this as a significant 'missing' feature on the Kx ... not to mention the build and top LCD ... otherwise, I would have considered it as a possible upgrade from the K200D ... let's see what happens with the next revision.

Using Aperture Ring Is Permitted
Is there any downside to leaving the [36. Using aperture ring] set to [Permitted] in [C Custom Setting] menu on the K-20D? I can't imagine that there is. But OTOH why is the option there, and set to [Prohibited] if it can safely be enabled at all times? Only rationale I can think of is as a w...

Using Aperture Ring Is Permitted
AFAIK the only reason for this setting is so that newbies are forced to find out how to shoot manual lenses as it does the flashing "F---" message and refuses to fire, so they have to learn about Stop-Down Metering. Once you have set it to "Permitted" you can forget this menu setting forever, the...

Using Aperture Ring Is Permitted
Once you have set it to "Permitted" you can forget this menu setting forever, there is no need to change it back again! Yes, just forget it apart from helping people on the fora who have just bought an old lens and wonder why it doesn't work. It must be the most FAQ of all FAQs! Best wishes, K.

M42
M42 adapters. Ideally buy Pentax, but in any event make sure you buy one that sits inside the lens mount on the camera, not the type with a flange that sits on the mount. The differance is infinity focus; you won't get it with the on-mount version, but will with the in-mount. Hope that makes...

Pentax K-x grabs the #2 spot in the Top 25 (new top selling DSLR charts)
Look at 18 & 19 - both are "PENTAX K-x two-lens kit (18-55/55-300)" just different prices. And there is a Kx at 69 too. That table is not very well thought out ... It should just list the cameras based on body type irrespective of lens or colour. You don't see tables of the biggest selling ...

K7 and Kx at up to 800 ISO
I paid £549.99 for my KX with two lenses (the short telephoto zoom option) I think it's extraordinary value for money and allowed me budge to go buy my Sigma 10 to 20. My son has a K20D which impressed me & persuaded me to have a Pentax SLR 35 years after I used to sell them. Neither of us fee...
