AF Limiter - focus range limiter
many lenses offer a focus limiter switch which is designed to prevent the lens hunting throughout the whole focus range when trying to lock auto focus or have the camera ignore subjects outside of the selected range
Olympus with the Olympus OM-D E-M1 mark II
have taken this a logical step forward and added such a functionality within the camera which can not only be applied to any compatible lens, but you get to specify the range from 0m to infinity with 0.1m precision
NB. currently it does not work with C-AF Tr mode (the camera may try to track on subjects outside the range that it can focus on) - use S-AF or C-AF instead.
how to set the in camera AF Limiter
in the menu, go to cogs, A1, AF Limiter
you get to set up to 3 preset ranges - just dial in the near and far distance in metres and make sure you leave the menu with it turned ON to one of the settings and you are done!
BUT, how do you know the distances to dial in?
use the preset MF functionality
now this is cool albeit a little clunky to have to resort to
ensure AF Limiter is OFF and lens AF limiter is OFF
set AF mode to Preset MF and press INFO then you can AF on whatever spots you like and it will give you the distance read out on screen with 0.1m precision - just what you need for the AF Limiter!
guess and trial and error
