dancook Posted July 3, 2019 Share #1 Posted July 3, 2019 Advertisement (gone after registration) Using Nikon compatible transmitter or flash. When you half press it focuses but the AF point doesn't stay green - then when you fully press to take the photo it finds focus again before triggering the shutter. This is a big pain if you are focus recomposing when the focus point is no longer on the subject. I was using this for professional work taking group shots so I had to use manual focus. The Leica Q2 locked up several times too and I had to reinsert the battery. Quote Link to post Share on other sites More sharing options...

FHPdoc Posted July 4, 2019 Share #2 Posted July 4, 2019 Ouch—disconcerting. I wonder if the same thing occurs with Leica flashes... Did you have to resort to your back-up to get the job done?? Quote Link to post Share on other sites More sharing options...

Did you have to resort to your back-up to get the job done?? I was using three cameras, 2 x A9 for event shooting and the Leica Q2 for flash shots in front of an illuminated sign - so that I would be dialed into the same setting each time. So I just resorted to using manual focus on the Q2 to get the job done, and then just pop out the battery and reinsert every time it crashed. I would like to know if people have this problem with a Leica branded flash, I wouldn't want to have to buy one to find out it's the same Quote Link to post Share on other sites More sharing options...
Leica Guy Posted July 4, 2019 Share #4 Posted July 4, 2019 Dan. I used an SF-40 extensively last weekend at a wedding reception. It mostly worked. No lockups. I felt more confident using it in manual mode although I did use it TTL some too. I often use Canon flashes on my Q and now Q2. Purely manual. No lockup’s. I do not have a transmitter other than Canon which I’ve never figured out how to make work on the Q’s. Sorry for your troubles. Buy from B&H and return within 14 days if it’s not meeting your requirements. 1 Quote Link to post Share on other sites More sharing options...

ralphh Posted July 15, 2019 Share #6 Posted July 15, 2019 (edited) If you're only using manual flash rather than TTL it might be worth looking at one of the chinese brand manual flashes. There's very little for the camera to get upset about as they only have a pin sync connection. I've used godox AD180 flashes in my studio for years and have only good things to say about them. They're a bit big for on camera (i used them on light stands with modifiers) but both godox and yongnuo make (or used to make) manual only flashes in a more shoe-friendly size too. If you want to get into putting the flash on a stand, the godox controller I have is fully manual with a sync pin only; again, very little for the camera to get upset about.

ralphh Posted July 16, 2019 Share #8 Posted July 16, 2019 (edited) yes but are they manual only ones or are they trying to have a conversation with the camera in Nikon language? My Q2 behaves completely normally with the AD180 radio trigger on the camera because there is only the sync pin - the camera probably doesn't even know the flash is there. You might find that putting the flash to full manual stops it trying to talk to the camera and upsetting it. Worth a go.

It looks like there’s a Canon version of the Pro ST-IV. Do you have any knowledge if it would work on the Q in manual mode with the Canon fladhes? So far I put one Canon flash on the camera in manual and it will trigger the other flashes only in optical mode. It would be nice to not have to dedicate a flash on the camera and use the transmitter. Again, all I care about is msnual mode. Thanks, The other Dan. 😁 I have many Hummingbird photos taken using the technique described above. Welcome, dear visitor!

The beauty of the Q2 is I have a lot more pixels to work with cropping. The 28mm lens is very-suboptimal for this type of photography. In years past I used a Canon 5D3 and a 70/200 lens or a 100 mm macro for hummingbirds. Its all fun. I used the Q just to try to do new things with that camera.

At the moment the shutter button is fully pressed down, the Q2 does this weird refocus thing and pictures are out of focus. I could currently only get around this problem by switching to MF, with a flash trigger on all AF modes fails to lock on including Face Detection. Have you found any new insights or solutions since then? Where can I report this severe bug? It is making the Q2 a handicapped camera for flash use ...

lx1713 Posted August 31, 2019 Share #19 Posted August 31, 2019 I'm using a Profoto Air Remote (which is a non-TTL) version. Works fine up to 1/1000 at full power for a Profoto B10. Bear in mind that while your camera syncs at up to 1/2000 of a second you will want to consult your flash's capability. It's duration. Check the T0.1s chart. It will show the flash duration for each power setting of your flash. For example the B10 can only deliver full power if your shutter is open long enough. At power setting 10 it's 1/400 of a second. So at 1/1000, if the flash syncs, you will have lost power outside of the 1/1000 time frame. I suspect that testing is really done on AC studio strobes where the flash durations are more powerful at shorter durations. But most people will want to use them with battery systems.
