Change Fast EV Switch buttons on A650IS (Juciphox CHDK)

Hi,

I have a A650IS.

The Fast EV Switch is really a killer feature for me, but the up and down buttons on the A650IS are flash and focus buttons, which renders this feature unusable.

Is there a way to change this so it uses the left and right buttons?

Thanks in advance :D

well right now the shortcuts are "hardwired" in the firmware, we may be able to code a user customizable shortcut menu soon.
are you sure left/right isnt mapped on the a650? or maybe not in all modes?

btw another useful tip comes from an unknown wikia user: you can use the feature for example this way: when UP enables/disables flash, and you want to up EV by 1, you can set the EV step size to 1/2, so you can press up twice - enables/disables flash and also ups ev with 1.
got it? same applies to DOWN. this is a workaround. a fix may come.
i'm thinking about using half-press & up/down, though currently there is some other shortcut (enable/disable overrides).

shoot_half + down activates mf on a-series (or at least on a710)
maybe shoot_half + left/right?
or, better yet, user-definable... :]

Hey,

On the A650IS you use the left/right to change EV +/- or to change the focus box position.
But both are used in conjunction w/ another button. You activate the focus position and EV by pressing this button.

On normal operation the left/right do nothing, so it would be really great if it did the fast EV switch.
But then Fast EV switch would have to be disabled when you're using the usual EV switch or the focus box positioning.

That would be the ideal for me anyway, I know you guys probably got more critical bugfixes and features to implement.

Ditto on a720.

Left and Right would be perfect. Nothing is assigned to them as is and a shortcut key that doesn't require a second key is always desired.
As is this is not usable, at least for me. The flash and focus menus (3 selections each) pop up with each press and are distracting and the workaround is cumbersome.

This would definitely be a feature I would use if I could assign left/right.

[edit]
What am I thinking... of course these buttons are assigned, unless you're in P or Auto modes. Although I use P quite a bit I spend most of my time in priority or manual mode. Seems like a user defined option would work best to cover as many cameras as possible.


Thanks !

Hej,
Wouldn't that be possible when you are in a mode where you can change change EV (Av, Tv, P), it detects when you are increasing EV on canon firmware, and once you have reach it's limit (+2), the right button becomes a shortcut and overrides it ?

Up and down anyway where not usable on my cam either, couldn't use macro mode and MF without overriding Ev.
