Lens Focus error on "lv"
« on: July 24, 2013, 11:02:56 AM »
Hi to all!
I'm getting an error when I try to move the focus of some step, it's simply two instructions:

Code: [Select]
int ret = LensFocus(-2);
lens_take_picture(64, 0);

the LensFocus function (lens_focus) stop and return at the first control:

Code: [Select]
if (!lv) return 0;

at the start of the function:

Code: [Select]
int lens_focus(
    int num_steps,
    int stepsize,
    int wait,
    int extra_delay
)
{
   if (!lv) return 0;
[...]

This return also happens with the Liveview active. I'm making some error?
My question is: can you move the af without liveview active?

Thanks!
Sigfrido
