You can choose the role to be played by the Fn (function) lever.
When ［mode2］ is selected, you can change multiple autofocus settings with a single lever operation. By storing separate autofocus settings for Fn lever Positions 1 and 2, you can recall the saved settings simply by rotating the lever to the desired position. The camera can store the settings selected for ［AF Mode］, ［AF Target Mode］ and ［AF Target Point］.
Storing autofocus settings at each lever position lets you quickly respond to sudden changes in the subject or other conditions.
When ［mode1］ is selected, you can reverse the roles of the front and rear dials. When ［mode3］ is selected, you can switch to movie mode by rotating the lever.
