Thank you very much MattMatic.

I found your comment helpful.

I was a little mislead by reading, more than one place on different Pentax communities, about setting an e-dial in the USER menu for P-Shift when in Sv mode would function as for changing Programme Line choise.

Now the world seems more simple and cheerful.

After reading that thread, I believe the end of the thread is misunderstanding the option in subject.

I believe that when the e-dial is set to control the programme line shifting, it's meant to be understood from the manual like you, anvh, stated:

Normal - the camera will try to get the optimum aperture and shutterspeed
High Speed - camera will try to get the fastest shutterspeed
Depth - camera tries to have the lowest f-number
MTF- camera tries to use the sharpest aperture

Thank you for that information and thanks to Aero for information on where to read out what programme line is in action presently.

I will give it a try if the K20D does it the same way.
It puzzles me why these informations are not in the user manual?

After testing, my Programme Line Shift set e-dail just operates the Aperture and in top display is nothing to be seen, nor is there in the VF og when pressing ifo button.

What is wrong here??
What do I do wrong??

Niklas

I guess there's not really any answer on this issue from us users nor from Pentax??

Niklas

Congratulation.
What a great photo.
I fancy lighthouses a lot.
What a pitty they are shot down in big numbers all over the world.

Niklas

P most of the time with Aperture on the rear e-dial, Shutter on the front e-dial and ISO on the front e-dial when OK button is pushed.
Green button makes camera decide.
Hmmmm
I feel I'm in full control.

Niklas

I wish I could come up with a short answer to that.
And I wish I could come up with a non-political answer to that.

For this community it would be comforting to announce that it's because every Dane has a Pentax.
However, that is not the truth.

I can assure you it's not a position of contentnes we are medicated into.

The Sea went in two tone colour due to local wind conditions.
I like the photo.

This photo makes me think of the famous Danish painter; P.S. Krøyer.
He painted some immaculate pieces of art at Skagen in Denmark.
Skagen is at the very north tip of Denmark in Scandinavia and has this very special light attracting artists from everywhere.

Judge on these two P.S. Krøyer painting examples:

In my User Defined Settings on the K20D, I have set up e-dials in Sv mode to have Sensitivity on the front dial and P-shift on the rear dial.

Now I wonder how to determine what P-shift, at any given time, is up in use, when turning the rear dial?

Will that show anywhere or somehow by the push of any button?
And will it be reset to whatever the standard choise of Programme Line when pushing green or any other button?

Niklas

I appreciate all the answers, some of which gave me new approaches for the use of fully manual lenses on the K20D.
Thank you very much.

However, it did not yet solve the ~4-stop underexposure I experience in low light conditions.

So if anyone has an input on this issue, bid in.
Elsewise I will hold on to Mannesty's explanation that it's a known and described issue.

Niklas

I have a few fully manual lenses like Petri 135mm F2.8 and the Kenlock 28mm F2.8.
Aperture is manual - without the A setting on the aperture ring.

Focus is manual as well. Not relevant in this post though.

My problem is that I find the meassurement of my K20D camera, with the Stop Down function on the Green Button or with Optical Preview, to be underexposing a lot in low light.
It is as much as four to six exposure stops wrong.
I.E.: F22. Stop Down and Optical Preview show the same meassurement: 3''
Correct Exposure is 30''

This goes for both lenses.

Is this normal?
Is there a way out?
