Exposure Lock when AF Lock is affected to "AEL/AFL" button?

Hello everyone,

Maybe it's a stupid question but I wondered if there was a way to assign Exposure Lock to a button when the Auto Focus Lock is affected to the AEL/AFL button.
My camera is an E-M5.3 but it may be similar to other Olympus products (mostly E-M1.2).

My standard configuration is:
- AEL/AFL mode 2, which means for shutter release: half-press locks focus, full press locks exposure and takes picture.
- metering on ESP
- AEL metering on spot, following the focus point.

I like this config very much, I discovered only recently that you can allow a different metering mode to the AEL button and to the standard metering, and this makes me use the AEL button much more often.

However, sometimes I want to have the focus assigned to the AEL/AFL button.
It's always the case in MF but I could use it also in S-AF sometimes.

Choosing AEL/AFL mode 3 assigns Auto Focus Lock to the AEL/AFL button. Fine, that's what I want :)
But now, is it possible to have another button to make an "on demand spot metering" as before?
I like the fact to have a dedicated button for focus, but I'd still need a button to do an exposure lock....

I've have read your post about 4 times and I'm still trying to understand it.

When you say:
"My standard configuration is:
- AEL/AFL mode 2, which means for shutter release: half-press locks focus, full press locks exposure and takes picture.
- metering on ESP
- AEL metering on spot, following the focus point."

Do you mean this USED TO BE your configuration until you "discovered only recently that you can allow a different metering mode to the AEL button and to the standard metering, and this makes me use the AEL button much more often."? So now you have the AEL/AFL button assigned to metering mode. Is that what you mean?

I'm not sure what you mean about AEL/AFL mode 3 and focus lock being what you want. Phew, too many options!

After trying to figure this out, one question I have - what about the shutter button? I mean, if you like having metering mode assigned to the AEL/AFL button, why not leave it that way and then configure the shutter button normally?

Yeah I know this was going to happen :)
I could have simplified the question.

And just to clarify, I'm not complaining, I like the amount of customization allowed by the E-M5.3
I'm just trying to know if I can get it a little better :)

In the past, I already had the AEL/AFL button affected to AEL, but it was with the ESP metering mode.
Now, I have:
- metering: ESP
- AEL metering: spot

So, with the shutter release I get an ESP metering.
And with the AEL button I get spot metering.
Which is great because when I want an exposure lock, I want it to be on a specific part of the picture.

In fact, what I'd want is a button for AEL spot metering, which would work independently to what I chose for AFL (shutter release half press, or specific button).

I'm not sure what you mean about AEL/AFL mode 3 and focus lock being what you want. Phew, too many options!
In some cases, mostly landscapes, having the focus each time you press the shutter is counterprodcutive.
The easiest way is to go to MF (having S-AF with AEL/AFL mode3 would be best - no risk of changing focus with accendently moving the ring - but it's longer).
But when I go to AEL/AFL mode3, I lose the AEL button that I like.

After trying to figure this out, one question I have - what about the shutter button? I mean, if you like having metering mode assigned to the AEL/AFL button, why not leave it that way and then configure the shutter button normally?
because sometimes I just want to have focus locked between shots.

I'm thinking that maybe you could get what you want by using the function lever settings and the various ways the 2 camera dials can be programmed. Rob Trek has an interesting YouTube video on this:


It's pretty complicated, but the various focusing modes and how the dials work in conjunction with it (for example, whether a dial controls exposure compensation or something else) gives an amazing combination of options. You could spend much of your time fiddling with those settings and never actually take a picture! ;-)

No. At least not as far as I understand it. The AE-L/AF-L function is programmed once (in menu A1) no matter how many buttons call it (menu B1). And there is no other function for directly calling spot metering with a single button press.

If you mean, move the lever, make the AEL spot metering, move the lever again. Yes it can work.
Probably the simplest way to go (easier than to get into menus, or change the metering mode twice via the SCP).
