This video was recorded on the Sony A9 with the FE 24mm F1.4 GM lens. The Atomos Ninja V was used to capture the Sony a6400 screen.

a6400, Im in manual mode.
While on Manual focus I want activate Autofocus to get the non moving object into focus and immediately go back to Manual focus.
I did what u explained on the video but it didn't work for me.
while in manual focus i press AF On assigned button and nothing happens.
Im i doing something wrong.
Btw i am in video mode.
Thanks! Sony has the worst menus in the camera world
Thank you for keeping it nice and simple appreciate it take care
great thanks sir
Thanks, helpful for setting back button focus on a6400.
But actually, I wish someone would explain how it works exactly. Do you press it and let go to focus - and lock focus, or do you have to hold the button down do lock focus? No one explains, and so far I can't get it focus lock regardless.
Hi JRE. If the lever is set to AF/MF and you press the button it toggles between autofocus and manual focus but you need to keep the button held down. You can still easily change this using the FB button or on the lens if there is a AF/MF switch. If you move the lever down to AEL and then press the button it will now lock your exposure so that you can reframe your shot without any exposure changes, this only works in the auto modes and since I normally shoot in manual I rarely use it. I only recommend setting it to the two buttons because if it's only set to AF/MF but gets knocked in your bag/case to AEL it might take a few shots before you realise that the AF is not working. I've done this before a few times myself! Hope that explains things better. All the best, Tim
Hi JRE. Just noticed that your question changed a little and UA-cam doesn't notify regarding edits unfortunately so sorry for the slow reply! To answer this one yes I'm afraid you have to hold it down to lock focus. It basically works exactly the same as the shutter button does when you half press. All the best, Tim
@@AlphaShooters I still can't wrap my brain around this. Does this only work in manual mode and not aperture/shutter priority? And when using it, must you keep holding the button or just press it once to lock the focus? I'm a little hesitant to change the functionality of these buttons because I do often switch between AF & MF, so how would I do that if I disable this button (if the lens doesn't have an AF/MF switch)? Why would be the argument for essentially trashing the designed function of that switch? And, does this make sense to even do if you're shooting handheld or is it only useful when using a tripod and taking longer exposures?
Edit: Lastly, one tutorial I came across advised to turn off Pre-AF, which you did not, citing that it defeats the purpose of BBF. Is there any reason why you left that on?
Great video, thanks!
Thanks for making this so easy! 📷❤️
Short and sweet. Thx. 📸

I have never been able to wrap my mind around back button focus but, then again; I have problems walking and chewing gum at the same time. OTOH with my two favorite lenses (Sony 85mm f/1.8 and 70-200mm f/4 G OSS) I have assigned the focus hold button on the lens to AF ON. This just seems more natural to me. I wish that all of my lenses for the A6400 were equipped with focus hold buttons. Since the A6400 has full time Eye-AF, I don't need to press another button to activate Eye-AF... Works for me!
Hey Richard, I tend to use bbf more on my full-frame cameras than on the smaller a6xxx series where I find that the button is a little on the small side. Using the focus hold button on the lens instead is definitely a very good tip, thanks! :) Two of my favourite lenses as well! Although I've just picked up the Sigma 16mm and 30mm 1.4 DC DN lenses which are super sharp! All the best, Tim
@@AlphaShooters I absolutely like my 30mm f/1.4 lens but, the 16mm, although a great glass is a bit large. I opted for a 12mm f/2.0 from Rokinon...
Lifesaver! I've lost too many shots w the wrong settings. Thank you!
In the process of selling my a6300 and awaiting delivery of my new a6400 - Just come across Alpha shooters - simply fantastic - very informative - well done and thank you very much -Thank you
Glad to hear you found the video helpful Ron. I hope you enjoy shooting with the a6400 too! Thank you for the nice comment! :)
@@AlphaShooters
My a64000 arrived and back button duly set up
@@AlphaShooters - I am seeking your help - On my Sony a6400 when I playback a recorded video clip I can barely hear the sound although I have set all the volumes etc to maximum - when I transfer the same clip to my Apple iMac the sound is normal and can be increased or decreased per the volume as I require - Is the sound from your a6400 speaker similarly very very low and barely discernible or more normal as one would expect - would welcome you reply when convenient - thank you Tim
Why would you want to do that ? 🤔🤷🏼♂️
i am waiting for the answer too.
My camera kept half pressing on its own without me even touching the shutter button ,I don't know if half pressing the shutter button is broken now but the custom buttons kinda saved it...so thanks a lot and if u know anything about the issue I said please tell me !!
Is it possible to assign the AEL to Registered AF instead of AF On? What do you assign AEL to in this case?
Do you set the AEL w/shutter (Exposure 2 page 9/14) to Auto, On or Off?
Hi! I have a Sony a6400 and 18-105 f.4 lens. During video recording I have a problem with AF during slowly zoom in and zoom out.
The focus is very unstable and the image is flickering, slipping .. I sent to you a link that you can see that problem that I don't know how to solve.
drive.google.com/drive/folders/1yLMIXUH7L4E9jGGUXLWplzIlq4h430zc
I can't view the link I'm afraid. Is this possibly just focus hunting? You'll see this around the edges of the frame if you are shooing a video of a relatively still subject. For my UA-cam videos when I'm on camera and sitting I'll typically use manual focus to avoid this. If this isn't what you are experiencing I'd recommend contacting Sony support for further help.
Hi, is the a6400 with the sigma 100-400 E mount, a good camera for bird photography?
Thanks
Yes, it is. The autofocus isn't quite as fast as the Sony 100-400 but it's a very good lens for the price. Tim
One big problem if you use this method. It works flawless in M-mode , but when you are in S- mode or A- mode using AF-C, AEL does not lock anymore. Now you have to set another customkey for AEL-hold. So now you have to focus on your subject, press another customkey to lock AEL , recompose and then press the shutter button. Or am I missing something?
This is true Leon. You'd want to keep the AEL button programmed for AEL in this case and just assignAF-On to AF/MF or another button.
Hello. Is there an additional setting I need to consider, if I use the Sony remote controller to take photos with BBF?
If you have back button set to the AF-On button on the camera then this is also mapped to the AF-On button on the remove. Apologies for the very late reply!
The a6400 sucks. After a year of owning it I still have trouble focussing and have to spend time watching videos like this only to nkt find the answer I need. This camera got great reviews but what a badly designed piece of crap.
Sorry to hear that Jim and sorry for the slow reply, your message went into the spam folder. How are you getting on with it now? Normally if set to AF-C and a wide focus area it should nail focus on most things! Tim
@@AlphaShooters Thanks Tim I'll try that.
Thank you I really appreciate this video
Glad it was helpful!
How can i set shutter focus ( half pressing )
Did you figure this out Ivo? Tim
This is exactly what I needed! Thank you. I liked that you assigned both positions of the button in case it got knocked. Perfect!
Tank you.......Germany
Thanks for the help on this. I've followed the directions here and am able to use BB Focus. The problem I am facing now is this: In Flexible Spot I can move the focus point initially, but once I take a photo the direction arrows on the focus point disappear and I can't move the focus point any more. Any ideas?
You're welcome Aaron. You need to assign "focus standard" to a custom key. This will then allow you to move the focus point. I'd recommend assigning it to the trash can because then if you click it once you can move the focus point around, twice and it moves it back to the centre. Hope that helps!
@@AlphaShooters This works perfectly! Thank you for such a fast reply... Much appreciated, Sir!
Hi
Can you use Iphone as a wireless monitor ?
I had a A6500 and I could do it on that.
How do you do it on the A6400 ?
Ok Boomer
