Focussing stops working after taking a snap

[jellison]

Strange issue I'm seeing in version 3.2.3 with a Canon 5D mark II where the focussing buttons will stop working.  To reproduce: 

1) Power on camera and connect BackyardEOS.

2) Select Frame and Focus to activate the live view.

3) Try the focussing buttons - they should work fine

4) Do Snap Image 

5) Press one of the focus buttons

6) Press Live View

7) Focus buttons no longer work

If you omit step 5 the focus buttons keep working.

From your description I am assuming that you do not mean that ASCOM focusing quits working.

So are you saying that if you press one of the lens focus buttons while LiveView is paused, that they stop working?

[jellison]

Yes I'm referring to the lens focus buttons in Live View.  Live View is running though, not paused. 

[astroman133]

OK, I do not believe that the lens focus chevron buttons work when LiveView is paused. From your steps, step 6 should pause LiveView which means that the image on the BYE screenj is no longer updated so even if the chevron buttons cause the focus to change you would not see it until you resume LiveView.

Live view is definitely running and not paused after step 6, I can see the image updating.  But the focus controls are not working at this point. 

The only way I've found to get it working again is to power cycle the camera.

Following steps 1-7, as outlined, I am unable to re-create your issue with BYE 3.2.3 and my T5i, or with BYE 3.5.0.RC7 x64 either. Although I will say that it does take a few seconds to download the snap image before I can restart LiveView.

Strange, thanks for looking anyway.  I'll attach the log file in case that helps.  Line 628 is my step 5 and then step 6 is line 629, after that the mouse focus clicks can be seen on lines 645 onwards but the camera is ignoring them.  

I'll have more of a play with the camera settings as well, maybe I've stuffed something up in there without realising.

You're not using the correct SDK/Drivers when connecting your 5D Mk 2.

Please select the other option and try again. Keep us posted.

Apologies, I was doing some testing - the issue is the same when using the other driver.

Can you send that logfile? Than kyou

[jellison]

Here it is. Same process as before - start live view, take a snap, resume live view and now focus buttons are inoperative.
