Pentax k3iii no green button. Just curious how its new feature works

Michael Piziak · 10-17-2021, 12:53 PM

I don't have a k3iii, but I noticed that the k3iii doesn't have a green button. Its new feature is that it doesn't need a green button.

I'm just curious how this works (with M lens) on the new camera.

The green button is on the back, below left of the focus "joystick".

Fwiw, there's a setting for M mount glass where it'll basically take a stop down metering before each shot. It's pretty awesome.

Yep...and the camera manual even explains how to use it.

The manual (page 118) Cautions:

When shooting using the automatic exposure control note the following points:

Images can be taken with the set aperture value but an exposure deviation may occur.
When shooting with the optical viewfinder, you cannot check the shutter speed and ISO sensitivity before shooting because the metering is performed immediately before the shutter is released. When shooting with Live View, you can check the shutter speed and ISO sensitivity before shooting because the aperture is always narrowed down.
When a lens with automatic diaphragm is attached, the aperture is narrowed down immediately before the shutter is released, causing a time lag in the shutter release.

It's a compulsion, though I am growing weary of addressing the obvious with certain folk, particularly when off-topic for a given forum.
