Originally posted by monochrome In LiveView mode is it an optical viewfinder? It can be OVF when the mirror is down and EVF when the mirror is up (oh wait, we already have that on the LCD), but how can it be both at the same time?
Here's how I think it'd work. The EVF panel is bigger than the OVF image, so there is an area around the OVF where shooting information can be displayed.
In EVF mode
- The image is shown just like a mirror less camera.
- Focus peaking and magnified live view are available.
In OVF mode
- The EVF does the job of displaying shooting information around the OVF. Currently a separate display is used. The difference is that you can now customize what information is shown and in what way.
- The EVF does the job of indicating active focus points by overlaying the OVF image.
- The EVF overlay can overlay previously unavailable information, such as a histogram or blown highlight warning on the OVF image.
- Blown highlights might seem impossible to assess without sensor readout, but the K-3 has a 89,000 pixel metering sensor, so I think that is probably fine enough to show highlights.
So if it is feasible to do it, I don't see many downsides to a hybrid EVF.
