Photon42 Posted August 7, 2015 Share #1 Posted August 7, 2015 Advertisement (gone after registration) I just found something slightly annoying when using the 24-SFD (A-Mode) and the Q. I know, it is not the latest flash model, but however, it reasonable in size and I have it ... Problem: When I activate the flash and try to lock focus by pressing the shutter button half-way, the focus is instantly unlocked again (focus box becomes green for a split of a second and then white again). Now I can configure the Q to only focus when pressing the AF/AE lock button, but this configuration is not my preferred one in all circumstances. And yes, I can manually focus, too. Any thoughts on this or anything I am doing wrong? Thanks Link to post Share on other sites More sharing options...

Cliff S Posted August 7, 2015 Share #2 Posted August 7, 2015 If I'm not confusing flash models, the Q won't work properly with that flash unless it gets a non-user firmware update. You may need to send the flash in to get the update. Link to post Share on other sites More sharing options...
Photon42 Posted August 7, 2015 Author Share #3 Posted August 7, 2015 I don't think the problem is with the flash - as soon as I have access to other flashes, I will try. I do not really care if TTL is supported. A mode is fine. It is just that the camera behaves differently in that it stops locking focus, when the shutter button is half-pressed and refocusses again, when it releases the shutter. Focus/recompose is therefore not working (short of the other two options I mentioned in my first post). Link to post Share on other sites More sharing options...
Big T Posted September 29, 2015 Share #4 Posted September 29, 2015 Same SF24 flash and same issue with the focus locking when shutter half pressed and then unlocking. I have been playing with the settings but nothing has changed. Flash works fine in "A" mode otherwise. TLL not working at all. Anybody else find a fix / work around?

viramati Posted September 30, 2015 Share #5 Posted September 30, 2015 Will check out with the SF58 to see if it has the same issue Link to post Share on other sites More sharing options...

@McLeica Posted October 27, 2015 Share #8 Posted October 27, 2015 Same SF24 flash and same issue with the focus locking when shutter half pressed and then unlocking.

Photon42 Posted November 3, 2015 Author Share #9 Posted November 3, 2015 No - not yet. I am hoping Leica will fix it at some point. I have sent them a mail, but who knows what will really happen. Link to post Share on other sites More sharing options...
Photon42 Posted November 3, 2015 Author Share #10 Posted November 3, 2015 I just tried with a Fuji X20 flash - no problem with AF cancellation (the Fuji flash does not have automatic exposure with the Q). Link to post Share on other sites More sharing options...
kingson138 Posted August 9, 2017 Share #11 Posted August 9, 2017 I know this post is a few years' old but the Focus Problems with SF-24D in A mode on Q could be solved by putting a thin durable tape on the hot shoe.It should cover up the two contacts before the centre one. I used a water proof fabric tape. The SF-24D works quite well using this method. In fact I placed a piece of Lee "228" Brush Silk Filter screen inside the Wide Angle adapter. The diffused light seems to work quite well.
