50mm 1.7 M aperture question

Posted 14/12/2007 - 15:52 Link
Bought an SMC 1:1.7 M-50mm for a tenner on ebay. Gorgeous little lens.
can't get it to stop down tho'.
Is there something I am not doing? I have set the custom setting to 'allow aperture ring' but that's all I can find.

Manual focus is fine, it's actually nice to go back to having fine control over the focus point but the narrow DOF is very limiting.

You have to stop it down using the stop down lever (around the shutter release) or the green button.

This means manual exposure only and stop down operation.

It does work, and it is a cracking lens. Using it at f1.7 all the time would be very limiting though.
Best regards, John

my m 1.4 only stops down when in manual mode on the k10.
Fired many shots. Didn't kill anything.

ah...that's cracked it. thanks. I thought it was working yesterday (beginning to think I was dreaming)

Finally found a use for the green button! yeh!
for any other newbies - you have to hit the stop down lever and then meter thru the closed aperture, either by twirling the shutter-speed wheel or hitting the green button.

I'm getting there slowly!
