M lens use

thegrasshopper · 04-02-2012, 01:21 AM

I have a Pentax M lens 135mm which I want to use on my new P5...........30o page instrustion book take time to work through [and full of techie langauge] and many things are beyond me!!

What setting do I need to use the lens on manual focus - I can use the lens but I have to use my old eyes to get focus correct - I have not been able to set so the it bleeps when focus is correct.

Any help would be appricated.

The P5 won't beep because it's a manual focus camera. What you can do, though, is take advantage of the split-screen focusing screen (I believe it has one) to verify that the image is in focus, and get a diopter appropriate for your eyes.

Once you get that taken care of, the lens should be quite easy to use in Av or M mode

Set C.27 (on menu page C4) to: 2 - Permitted.

On the Set-up (spanner) menu page 1 ensure that the Beep volume is turned up. If set to 0, the beep is turned off. See p.288 of the manual. When adjusting this volume ensure there is a tick in at least the first of the following beep selection boxes below it:

In-focus
AE-L
Self-timer
Remote Control
Mirror Up

LV is great for static MF use. See:

thegrasshoper is talking about the P5 also known as the P50, which was created in 1986 and sold until 1989.

You got it, it's not a typo

Then why is it in the K-5 forum? I also rather doubt that the P5 had a 300 page instruction manual. The manuals in those days were only about 60-70 pages. Using a M lens on the P5 wouldn't have been a problem at all. It only would have worked in Aperture Priority mode or Metered Manual mode.
