Guest Posted May 12, 2019 Share #41 Posted May 12, 2019 Advertisement (gone after registration) When I focus on granny’s nose and half press it locks the focus on granny’s nose. I can re compose and fire the shutter and granny’s nose is still in focus...........not a pretty sight but still in focus 😂😂😂😂😂 Quote Link to post Share on other sites More sharing options...

If in 4 you keep the zoom lock button pressed then focus will remain on Granny. All the best Jono Does anyone know whether that behavior has changed to proper back button focus behavior? In other words, to 6) press the shutter and the camera will NOT re-focus and keeps the granny's nose in focus (given Ms Granny did not move around ...) ???

harmen Posted December 10, 2020 Share #45 Posted December 10, 2020 Better late than never? I was curious as well and just read through this conversation. On the new Q2M, I can use the back button for focus and do not need to hold it. In the menu, set Customise Control, Zoom/Lock button to AF-L. Then turn the focus ring to AF. Press the back button and it focuses. When I then half-press the shutter button, it does not refocus. (It does close down the aperture and lock exposure, so it may seem to focus if you had set a narrow aperture...). After taking a photo it will start afresh and if you don't focus with the back button, the shutter button will also trigger focus. Finally, I noticed I may need to hold the back button for a moment until it establishes focus. A very short press does not always work. 1 1 Quote Link to post Share on other sites More sharing options...

The implementation in Q2 and Q2M is not what is conventionally called BBF. BBF completely disables focusing via shutter and triggers AF every time the rear button is pressed. 1 Quote Link to post Share on other sites More sharing options...
harmen Posted December 11, 2020 Share #47 Posted December 11, 2020 Advertisement (gone after registration) Yes, a very different experience from my Nikon, which I use exclusively underwater. But, then, the Q is probably at its best in manual focus in such situations. I find the finder just about good enough to focus without peaking or magnification. I use it manually 95% of the time. Not as fast as an M though. Quote Link to post Share on other sites More sharing options...

I find the Q2's BBF variant confusing and also use MF instead, which works really well both on Q and Q2. 1 Quote Link to post Share on other sites More sharing options...

I find holding that tiny button in very difficult and don’t use it. 1 Quote Link to post Share on other sites More sharing options...

You do not need to hold the button, one press locks the focus ... until you half-press/press the shutter. Yes the button is tiny, but it worked OK for me on Q. 1 Quote Link to post Share on other sites More sharing options...

Unfortunately on the Q2, even with the latest software, this is not the case. Unless one keeps the back button pressed it refocuses when one presses the shutter button. It surprises me that this is not the case with the Q or the new Q2M. Quote Link to post Share on other sites More sharing options...

Assign AF-L to Zoom/Lock button, press once to lock focus. Pressing the shutter to take picture does not refocus, but it unlocks the focus.

So, Assign AF-L to Zoom/Lock button, press once to lock focus. Then the shutter button will not refocus and the shot is taken with the pre selected focus point. Please tell me this is the case, as in any half decent back button focussing set-up. Apologies for reviving this old thread, but for someone who has been considering buying a Q2 this has been a concern. Quote Link to post Share on other sites More sharing options...

When you assign AF-L to Zoom/Lock button, pressing the button will focus and lock focus until you take a picture. After taking a shot, the focus will be unlocked and activated via the shutter button unless locked again with the Zoom/Lock button. With multiple shots, you have to lock the focus repeatedly. It is not the typical BBF behavior. 1 Quote Link to post Share on other sites More sharing options...
keithlaban.co.uk Posted April 14, 2021 Share #56 Posted April 14, 2021 Many thanks, SrMi. So, no way to have typical BBF. This is so unfortunate and I'm afraid rules the Q2 out for this photographer. Quote Link to post Share on other sites More sharing options...

The Q2's BBF situation is unfortunate, but Q2 and Q2M are still magnificent camera, and I enjoy using them. I was willing to adapt :). BTW, they work very well with MF. 1 Quote Link to post Share on other sites More sharing options...

I only use BBF on my DSLR’s and pro Mirrorless cameras. Frankly with the Q2 being a moderately wide angle focal length BBF is not very important. Definitely not a reason I’d reject owning the Q2. It’s a fantastic and fun camera in spite of BBF not being well implemented. 1 Quote Link to post Share on other sites More sharing options...
