Have you considered that they may well be of different thicknesses, are incredibly easily marked. You might be better off just buying a replacement screen on ebay.

There are plenty articles on the net about how to cut down a screen to fit on Pentax Digitals. Just Google.

The focusing screen is a critical component, so the DIY approach looks very flawed to me. It's the actual screen construction, the thickness, the size, all needs to be correct. Why spoil a perfectly good camera with uncalibrated replacements?

The screen catcher is a good idea, even for someone just removing a screen. I notice that your original page has a link to greyhounman's site in which he says the DS and ME Super screens are both about 1.5mm thick. I think some of the Chinese suppliers use a FF Nikon screen, which is widely av...

It gets worse...a Nikon screen cut down and put into a Pentax camera? Maybe it's just me, but I'm amazed that anyone would even consider it as an option.

Just be careful. I seem to remember that split focussing screens can affect the cameras autofocus - it's been a while since I heard this but know there are a couple of old threads somewhere.

I'm just amazed that anyone could be bothered with the hastle and the lack of precision in a critical component, I think John is referring to spoiling your new camera, not the old one :wink:

A split-screen isn't that accurate anyway. I mentioned in another thread that I've just tried my old ME-F with the 35-70mm AF Zoom and it still works a treat :wink: Switching to a MF 50mm f/1.4 the Green light is very sensitive much better than on digitals. It even lights up 2 red arrows showing...

Pentax offer a selection of screens that are actually designed for the job.

Pentax offer a selection of screens that are actually designed for the job. there's a thought but introduces the budgetry issue sadly. Can only 2 at Pentax but no split, and at least $100 to me anyway.

Well the P30T arrived. The screen seems very bright, the split collar doesn't partially black out until f8 and the diagonal split is extremely finely etched. Can't wait to get it on-board the K-7 :) Pete
