Leica Q Feature Request - Focus Override.

Advertisement (gone after registration)

I'd like to assign the rear AF button (digital zoom by default) to give me a centre point focus whilst held down (without engaging AF)

 

I shoot wide area / face detection most of the time, but 10% of the time when it's not giving me the focus point I want I'd like to override it.

 

This way I can get the best of speed & automation, and overriding for precision control without going into the menu.

If anyone is not familiar with this approach - the Sony A9 has a significantly more advanced setup over-ride feature, it allows you to temporarily switch many camera settings whilst a button is held.

For example, bird's in flight

 

(af-c = continuous, af-s = static)

 

For birds in flight you'd typical shoot AF-C, perhaps wide area focus with a high shutter speed (often leading to high ISO) - the bird lands, sits in shade and your settings are now sub-optimal. You can program the camera so when a button is held it switches to AF-S, single point focus, a slower shutter speed for better ISO - the bird takes off again, you let go of the button and it switches back to your 'birds in flight' settings.

 

It's unlikely you'd use the Leica Q for BIF though.

 

For weddings I typically use single-point AF tracking with AF-C with face detection enabled, and a button to track the eye - but sometimes it picks the wrong subject or chooses a poor AF point on a static object - so if have set it up so that I can hold down a button and it will provide single point AF with AF-S - so I can AF on the subject without it looking for faces or try to track something.

Nice idea! I also use face detection in street photography but sometimes I’d like to quickly switch to selective focusing, having a button for that would be awesome.

great idea...though I'd like the option of having it the other way around, i.e. from single point to face detection
