K-3II - Stop Down Meetering

hoopsontoast · 06-22-2015, 02:24 AM

I have been racking my brain why I can not get Stop Down Metering to work in 'M' mode with the Green Button in Live View.

Works fine through the viewfinder as it should, but in Liveview with focus peaking on, the green button makes the same noise to take the reading but the exposure duration does not change.

This is with a number of lenses including 'A' and Manual lenses (FA and K).
Also with the E-Dial settings on 'M' Mode set to 'P-Line', 'AV-Shift' or 'TV-Shift' seems to make no difference.

Am I missing something in the settings?

I actually haven't tested this with a manual lens, but in M mode in live view, the K-3 does preview the actual exposure, so it's possible that the lens is already being stopped down. If not, does the shutter speed change when you activate DOF preview via the on/off switch?

I'll look in to this tomorrow to see if we're missing something obvious.

In Live View, in 'M' Mode, the DOF Preview does the same as the Green Button (stops down to the desired f-Stop) but the shutter speed does not change. The Lens is being stopped down with both the DOF Preview and Green Button as it should but the Shutter Speed is not being changed.

Just to add, I am using the D-BG5 Grip and the green button on that does the same (just to rule that out).
