Bill for years with Canon and/or Sony I was a back button focus shooter.
That changed with the a9/a7riii and the RX10iv.
I was and still am a manual shooter except for auto-iso. The Sonys, even the 1 incher
are so good with noise I let iso do its own thing.
But with the newer Sonys I'm kinda back to shutter release AND back-button focus.
The reason is Recall Custom Hold.
I have the AEL button mapped to Recall Custom Hold.
You have 3 Recall Custom Hold settings.
Setting 1 is the one I mapped to the AEL button which is again my back-button focus.
I did this by going to Custom Key in the menu and selecting AEL and then scrolling through
and choosing Recall Custom Hold 1
Setting 1 has these parameters-
Continous Shooting High
Exp comp -0.3
Focus Area is wide.
But I can set any of those to anything I want=shutter priority, 1/2000, a set ISO, exp comp 0, center metering, etc.
This is a situation where I'm spinning the front wheel and back wheel doing my own thing say for a portrait and then suddenly
a BIF opportunity jumps up. I instinctively put my thumb on the AEL button, get the green boxes on the Ibis and index finger release
Remember you have two more Recall Custom Holds.
For a perched bierd I mapped C3 to Recall Custom Hold 2-
expo comp 0.0
I thinking mapping a function to a 'C' key is a powerful feature of the RX10iv. Being able to set up all the parameters mentioned above
to a particular key is awesome.
Moving on. You've already seen or read that the 1 inch sensor like the mFT sensor is very forgiving for DOF. I just keep my aperture ring on
the lens to F2.4. It will go up as need be when I zoom out. I don't think...unless being artistic/sun stars/etc....that we want to go past F8
anyway with this sensor. I'm shooting long most of the time with the RX10iv so F4 is my norm.
OK, hope that helps a little
