Question Back Button Focus

I've set my camera to have the F1 button serve as focus activation. AFL/AEL is set to Mode 3 in custom menu. Is there a way to set separate exposure lock? Setting AFL/AEL to a second button doesn't seem to do it.

When using the camera in traditional way (Mode 1) I could focus with half push of shutter and exposure lock using the F1 button since that button's designation is AEL/AFL.

Anyone have experience with this? Any ideas?

Re: Back Button Focus

I see what you're getting at. When using the MF Mode 3 for 'back button focussing' the only way to set exposure is with the shutter button (half press). When I use AF I have the AEL button set for Spot Exposure metering but for the above the Spot Exposure would need to be set first as I don't know of another way to separate the two AEL & AFL. Actually (a bit more useless information), on older (Olympus) DSLR models there was a choice to have momentary AEL or locked (Memo), but that isn't available on the M4/3's models as it is just 'lock' now.

Re: Back Button Focus

Thanks for trying :-) I take some comfort in thinking that most of the situations where I shoot continuously, exposure variation between subject and rest of framed scene will be minimal.

Re: Back Button Focus

Here's a link to a pdf file that has setting up back focus to the fn1 button. I use this method!
