Can I trigger a script using OVF only ?

[D600vince]

Hi,

I'm wondering if you can asign script to physical buttons, so using optical viewfinder only on the field, pressing those asigned button will perform the script.

For instance I'd like to take 6 pictures in burst mode each time I press the shutter release. So I'm planning on writing a script called six shots, that when enabled would transform my shutter release in a 6 frame firing machine (yes because only relying on pressing the shutter doesn't exactly gives you 6 frames).

Another script set-up to another button, will set my exposure to ETTR.

But I'd like to use them with my ovf, so not in live view mode. Is that possible ? Maye the ETTR one not because it might need access to liveview to get exposure ?

Thanks.
