I was shooting an M 75-150mm lens today. Much easier. Really cool! Do you like the Playback button where it is? I swapped it with the down dpad screen brightness button and find it a lot easier to use.

With my K70, I think I have to depress the green button, while in M mode, to get the exposure. Looks like the K3iii does not need the green button pressed, even in Av mode? Do you need to press the green button in M mode?

I’ve been shooting in catch- in-focus with M lenses for years the cameras act to me like they take a espourse reading when I check the focus. I always forget to use the green button on my newer cameras as my older cameras my *istDL and K100D do not have the green button for espourse

The Pentax 50mm f2.0 was my first lens back in 1977. Oh crap I’m old.

When shooting with my Pentax-M 50mm f/1.7 on my K-r, I used to slightly loosen the lens (push the lens release button and turn the lens just enough to free the aperture lever), and then I could shoot in A mode. It was a bit of a clumsy workaround, but it could be handy sometimes.
Stop down metering in M mode was still more accurate though, and easier to focus with in lower light.

It’s cool that this is now properly handled on the K3-III – that feature and that big bright viewfinder must make shooting with fully manual lenses more fun that ever. I would definitely forget to change the aperture value for the exif though!

Thanks for the video, Lee : )

This is a huge selling point for Av shooters with lots of M lenses. The way I think they achieve this is that whenever the camera does not detect an A lens or newer, upon pressing the shutter button the lens is stopped down, the camera reads the exposure and sets the shutter speed accordingly right before activating the shutter. As you demonstrate, it appears to be instantaneous. It would be interesting to measure the lag in this process and find out whether or not previous bodies were capable of using this approach. Would it have been due to hardware limitations or was it because nobody had thought about it before? Anyway, I think it’s brilliant.

Hi Lee, in AV mode, the difference with the K-3ii from older models is that the camera automatically stops-down and activates the exposure meter just before the light hits the sensor as soon as you release the shutter. This is why the shutter speed is only displayed as “AUTO”. Such a cool feature to add!

I’ve shot on manual mode and missed some captures. So, my wildlife photography is always on AV mode. All other settings are manually defined.

Exactly: K5ii and K3ii only consider aperture in M mode. All other modes shoot wide open. But since I mostly shot wide open it is fine. I actually hacked my M50/1.4 to not open all the way and so I had roughly f2 all the time. And camera operates outstandingly this way. Why f2? Lens get really sharp at that aperture. I just stick a tiny plastic particle to limit aperture lever not go fully.

If I understand you properly, new “katie” actually uses aperture lever in AV mode, so camera adapts to what it is set on lens, rather to only shoot wide open? That is outstanding. Yet another + for new camera. I love old M lenses.
