Preliminary patch, requires platform_camera.h modification and stubs rebuild. DryOS r23 or later. Did not do a full rebuild to check whether MoveZoomTo is always identified. Also missing is the t2 sigfinder mod.

Here's the trivial t2 sigfinder patch.  The EOS M cameras just return, as expected.

Initial observations on sx710
With CAM_USE_MOVEZOOMTO, set_zoom returns immediately, where the previous versions block until the zoom finished. Keeping compatible behavior would be good, presumably the zoom_busy loop could be used.

Using set_zoom cancels digital zoom from the "digital teleconverter" setting

Distortion correction appears to be equivalent between set_zoom and manual zooming. I only checked one focal length (50mm equiv, zoom pos 19).

Zoom wait seems good.
I tested on elph130. Results mostly similar to sx710. One thing I noticed, there only seem to be 2 zoom speeds. with < 34, a moving full zoom range takes ~7 seconds. At larger values, it takes ~1.5. Tested like
Code: [Select]
=set_zoom_speed(32) t=get_tick_count() set_zoom(get_zoom_steps()) return get_tick_count()-t
=set_zoom_speed(32) t=get_tick_count() set_zoom(0) return get_tick_count()-t

The initial value of mzt_speed is 1, which corresponds to the slow speed. The fast speed seem to be the one you get using the zoom lever or the old set_zoom.

SX710 also shows only two speeds, but the first two are slow: <= 66 takes ~3.7 seconds, while > takes 2.2. Again the faster speed seems like the "normal" one to me.

Forgive my ignorance, but will this approach allow one to move from a known position in mm to another position in mm.


Or 'just' move with no positional feedback?


...and on a G1X and G7X  ;)

This change mainly affects zoom, not focus. It exposes the same zoom steps as the existing set_zoom. The impact on focus is only related to what happens to the focus position during / after zoom, and crashes connected to trying to set focus.

Many thanks for the insight.

Ixus150: this one has a single speed zoom lever. Zooms fast when not recording video, slow while recording. Those 2 speeds are available for MoveZoomTo.
sx280: multi-speed zoom, but only 2 speeds are available at a given time when rotating the zoom ring. (slower when recording). Did not test all possible speeds with MoveZoomTo.

The initial value of mzt_speed is 1, which corresponds to the slow speed. The fast speed seem to be the one you get using the zoom lever or the old set_zoom.
Indeed, I looked up PT_MoveOpticalZoomAt in one (multi-speed) firmware and it sets zoom speed to 3.

I checked a few firmwares and the highest zoom speed is 3, in all multi-speed cases. Zero also seems a valid speed.

So, v3 of this patch sets the default speed to 3 and translates the 0..100 range of lens_set_zoom_speed() to 0..3.
Single speed cameras ignore the speed parameter, so 3 doesn't hurt them.

Romlogs without any information about how the crash occurred are not useful. If you want a bug fixed, give us enough information to do something.
