Um, what's the prop again please to change how the camera starts af (by backbutton (=1) or half shutter (=6))? Is this the same across all models? Thanks!
You have portable wrappers for this.
lens_setup_af(AF_ENABLE) or lens_setup_af(AF_DISABLE).
The first one will move AF to half-shutter (so when ML takes a pic, it will autofocus). The second moves AF to back-button, so when ML takes a pic, it will not autofocus.
After that, lens_cleanup_af() will restore your original setting.
You can also pass AF flags to lens_take_picture (second argument).
A little more low-level: assign_af_button_to_halfshutter, assign_af_button_to_star_button, restore_af_button_assignment.
Thanks, I didn't realize it'd be that elaborate - though lens_cleanup_af() is just a wrapper for restore_af_button_assignment() so you could very well do without the wrapper :->
The lens* ones only change things if you have autofocus. Reason: they don't slow down bracketing if you use MF.
Here it does sound a little faster if you bracket in MF, and that's the reason.
