That's a good question. Normally it doesn't. For some reason yesterday while I was working with the crow, the dial was set to Tv mode (since any old mode will just turn itself into Av mode with an M lens and I wanted to work wide open) and when I had the Sears 135mm on the camera, it recorded the aperture as f2.4. The lense's maximum aperture is f2.8, so somehow it at least seems to have picked the right aperture but was off by a tiny bit. Then when I switched it for the 50mm f1.7 it turned to f1.4. I have no idea how or why it did that. A few frames later it stopped recording the aperture and went back to normal.

Though I really wish I did have the 135mm f1.4 the EXIF claims I did.

...I'm wondering if there's a way I can modify this lens to constantly stop down to the aperture set on the lens, thereby allowing stop-down metering in Av mode like I had with my old screwmount.
You can saw off the actuator lever. That is a mean thing to do to a perfectly good M 50/1.7.

My advice is to work with the lens for awhile. Having the diaphragm wide open for focus without having to fiddle is a real advantage. In practice, you should only need to meter the subject once. You can then compose/focus/shoot as much as you need until either the subject or the lighting changes.

Did a bit more searching for other M 50mm f.17 pictures on Flickr and it looks like what I'm seeing on my side is normal then, ie for aperture info not to be recorded in EXIF data for it.

I see that the A 50mm picks that up... That plus being able to use in AV mode might put me into lens hunting mode again :-)

I have been working with this lens and other M and screwmount glass for ever since I started into pentax. I'm well practiced, I promise. For the photoshoot that the shot above came from, I did indeed shoot most of it in manual without needing to meter. The thing is that I generally use this as my walkaround lens as well, and changing light conditions are the norm, and I end up using a range of different apertures if it's convenient.

I don't know if I'd really call it mean. I consider the M 50mm f1.7 a "lens for life" from my end, and being able to use it in stop-down Av mode would just let me love it even more. That was what I loved about my old Meyer-Optik... just depress a pin on the side and it stopped down. And it may possibly be necessary to use it (eventually) on a 5D if Pentax never brings out that affordable FF...

M 50mm f1.7 @ F1.7, ISO 2500, 1/50th on the K-x. Messed with the exposure quite a bit in LR3beta, then sent it through some heavy neatimage. This is getting printed up as posters for a local show on saturday night.

I was waiting for the red eyes but then saw the flash on the upper part of his eyes. Great shot.

georg ... thanks for the comments .... I just realised you can see the flash in the window behind ... bad error on my part ... although it has taken me this long to realise it anyway.

Nice natural light shot of the orchestra ... also nice to see a bit of motion blur as well .... just to portray a bit of movement/action

If it takes so long to really see it, it doesn't really matter imo. Other than on photo forums with meticulous viewers of out-of-focus areas :-)

That's right, I've tried to get the moment when the conductor does the big stroke downwards and some musicians start moving rapidly .-)

Talking about movement, here's a fun shot from a pitch dark scenery, only possible with the shake reduction I guess:
