Prime lens focussing problems
Richard I have found that the green hexagon is hit or miss for manual focus confirmation, but not by the amounts you are seeing. Bur split prism screen is the way to go for sure.

Prime lens focussing problems
Ahh, the green hex when using my Pentax-A 28-80 is miles out too, as it is with the Sonnar, Flek and Helios. I think if you are going to use manual focus, you need to manual focus. If you are going to turn the ring until the camera says stop, then you might as well let it turn the ring :wink: I l...

Ok I use the K10 and this is how I can use it: Manual focus lens only. Set camera to AF-S Press and hold shutter button, and slowly turn the focus ring. When the camera aurofucus system thinks the image is in focus, the green hexagon will appear and allow the shutter to release. N...

Again not a K200 but it works for my K100d Super With Manual Focus lens set camera for AF. Fully press and hold Shutter Release. turn focus ring until shutter operates.

I see from the online manual that, like the K20D, the K200D also has an option for Catch-in focus in the Custom menu. This is turned off by default. Set it to On to use the feature. http://media.pentax.co.uk/downloads/photo/en/19541/K200%20manual.pdf

Having tried this on my K200D, I can confirm that the procedure works! You have to enable the Catch-in focus in the Custom menu, and it works for manual-focus lenses only.

catch in focus
Sorry to resurrect an old thread, but I am having some issues with trap focus. It works brilliantly on my Pentax M 135mm - in either M or Av settings, but doesn't work at all on manual M42 lenses with adapter. Why is this? The M 135 has no electrical contacts, so how does the camera know which le...

And the answer is?

And the answer is? M42 lenses are so small, they don't touch the contacts. There needs to be contact to activate catch focus. There is a trick with some alu-foil to shorten the contacts. But that is camera depended. Martin.

Yeah, as Martin said, the M lenses work because the metal flange of the PK mount shorts the contacts. Most M42 lenses don't have anything metallic there, so unless you use a flanged M42-Pk adapter (and lose infinity focus) you need to short them with foil or something similar. I have read in seve...

Having tried this on my K200D, I can confirm that the procedure works! You have to enable the Catch-in focus in the Custom menu, and it works for manual-focus lenses only. It also works with SDM lenses having a manual focus switch on the lens body set to "OFF". When you have a subject moving t...

Problem solved, in a hopefully semi-permanent way, with a piece of aluminium foil wedged under the M42-Pk adapter :-)

Agreed, John, but the sellers feed back is only 34 and he's used a stock photo. Still. Just checked the price, now at £100.
