Lens problem with Pentax K100D

Discussion in 'Pentax' started by cyrusthevirus, Jun 1, 2007.

  1. Last week I bought a K100D, mainly because I have some nice
    Pentax lenses from my previous film cameras, both K and 42×1.
    Today, while testing a non-automatic 50 mm (Pentax-M), I
    noticed it is used only at full aperture.
    Is there a way to use it "stop-down" or something similar? I
    don't care to use it in totally manual mode or to have a
    darker image in the viewfinder.
    The manual, even if very detailed, is not very useful.

    Thanks in advance

    Use "M" mode, set aperture on lens, press and release AE/L
    button to automatically stop down lens to meter and set
    shutter speed. Press shutter to take picture ;-)

    Thanks a lot for your hint, John!
    As future memory (so I can google if I forget it) and as
    reference for other K100D users here it is the whole
    procedure I found:
    0) set the preview method (Menu - Custom Setting) on "optical"
    1) shut down the camera
    2) change the lens
    3) set focal length for shake reduction
    4) set the camera on M (manual exposure)
    5) press and release AE-L
    6) turn the ON/OFF button clockwise on the 3rd sign (preview
    position) to meter: it stop down the lens and it is possible
    to see in the display the "difference from the appropriate
    exposure" (manual, p. 145)
    7) turn the e-dial to adjust the shutter speed
    8) turn the old aperture ring on the lens to adjust the aperture
    9) cheese :)

    Just to demonstrate it works, I uploaded a "screens hot" of
    this reply on Flickr:

    Thanks again.

    You don't need to use 6 and 7 if you set aperture (8) first,
    then press AEL (5), which meters and sets shutter speed
    automatically. You can of course use 6 and 7 if you want to
    meter manually, in which case pressing AEL in step 5 is
    completely unneccesary.

    You're making it all sound a lot more complicated than it
    is, but whatever works for you ;-)

    I'm quite old-fashioned (¹)...
    I noticed the procedure can be simplified, but it was almost
    late when I wrote the message.
    Today I'll make some tests with my old 42×1 macro bellow.

    Thanks again

    (¹) the day someone will make a cell phone with a rotary
    dial I'll buy it ;-)
