No green button on *istD

...what do I do now? I have used searches to no avail, everything I read about stop down metering on Pentax DSLR's refers to "the green button," "the green button..."

Still haven't found clear explanations of stop down metering with manual lenses when using the DL, like I am. Do I have to meter through the menu somehow, or am I just out of luck completely??

Thanks!
Marty

(edit) Let me explain the method I have been using thus far:

1) Use M mode
2) Set the aperature manually on the lens
3) Keeping the shutter button depressed halfway, I focus, hit the AE-L button, and shoot

I am guessing that's correct. I was just wondering if this method can be used in Av mode as well, with fully manual lenses.

I've written an article on how it's done: https://www.pentaxforums.com/forums/pentax-lens-articles/110657-how-use-manua...7-k-x-etc.html

I believe that on the DL, you have to engage the DOF preview to get the camera to stop down and meter properly. That's how it was on my *ist DS, but it sure has been a while!

You have to be in M mode; otherwise, the camera will not fire.

On Pentax cameras without a Green Button, you need to be in Manual exposure mode and to have enabled/permitted the use of the aperture ring.

While metering is activated you then beed to press the AE-L button. The lens will momentarily stop down to the aperture set on the lens and the correct shutter speed will be set.

Using the DOF preview lever will only stop down the lens, it does not set the correct exposure.

Clarification: on *all* cameras, you need to be in M mode in order to use stop down metering. The only difference between models is *which* button to press to do it. On cameras with Green button, it's that one. One other models, it's a different model. On the DL series, it's the AE-L button, as described in the manual.

Thank you all... as you can see in my original post, that was the method I was using. But I didn't arrive there by reading the manual, as the verbage of the manual is not necessarily always beginner-friendly to people with little experience... nevertheless, I have managed to sort it out thanks to trial and error.
