Old k lenses

Hi, does any one know how to enable the use of k lenses with the k3

Thank you
Dave

Select [Enable] in [27. Using Aperture Ring] of the C4 menu.
Use exposure Mode M
Press the green button to take a meter reading.

There is further info on this on page 84 of the K3 manual.

It's in The "C" menus. You have to allow "Using Aperture Ring".

Quick typing there John

Thank you
Regards Dave

If you demount the lens and turn it about 10 degrees you can use the lens in AV mode and it will meter without the green button

Also gives 'depth is field preview' as it stops the lens down!

You mean, insert lens into the mount in the usual way but only turn it 10 degrees? This is a new trick for me.

10minutes later ........

Good Heavens. It works with a K5 and a Chinon 50mm f1.7 - bit risky with the loose lens though. The info says it used f1.7 nevertheless -- it didn't -- it stopped it down to f8 so, although it works it doesn't report truthfully

It will not report aperture as there are no contacts but if you want a secure lens you can ddrill a 3mm hole in the lens mount about 10degrees form the lens lock on the mount and it will fit on the camera securely
