- The best-selling author of e-books for Sony cameras explains the different focusing areas and how the camera makes its focusing choices.
This demonstration uses the Sony A9 camera, but most Sony cameras circa 2019 work the same way.
Things Gary talks about:
Choosing a focusing point
Is the camera blind to horizontal contrast?
How the camera chooses what to focus on.
Tracking subjects across the screen using Lock-on AF

This is very helpful. Thank you!
Excellent, your explanations are easy and hands on. I like them. And with the Lock-On function on the Sony A9 my way of taking Wildlife has completely changed. It is a function I never experienced on any other camera system, it it is not perfect but it is coming close to that. I got images I would not get with any other camera system. Well done, Sony.
Really well explained. Thank you.
You're welcome. Tell the world! :-)
Excellent explanations! Please update this for autofocus changes in latest firmware.
Gary Friedman I do own the A73 book. Will check my email. Thanks!
Very clean explanation, thank you!
awesome example tutorial. great stuff. Sony camera tech rocks!
Thanks 🙏🏼 excellent video
Thank you!
I’ve had the camera since it came out. Although I’m happy with my set up it’s good to learn other options. Great video
I’m watching the metering video now. I’m curious. Have you ever reviewed lenses. I’m looking at the sigma 35 1.2. Vs the Sony 1.4.
And what does 'Flexible' mean in Flexible Spot?
I can also say that I see some signs in firmware 5.0 that the A9 can learn to lock onto a horizontal. I was doing tests on a power line. When I was metres away it would work, but not when tens of metres away.
Re 'Lock-on': this is in firmware 4.1. 5.0 has Tracking instead. This is a whole new ball game: it can work very well but it's not magic.
i prefer your video tutorials vs. e-books. Are you planning a video tutorial type of videos also as an alternative to your e-books.
Of course you prefer them - they're free! :-) Anyway, the only reason I've made these particular videos is because these are the concepts that are difficult to get across in writing. Some things are much easier to understand when demonstrated. But the books are over 700 pages long, going into every detail, and it would require hundreds of hours to convey the same level of detail in a video. Plus, videos take considerably longer to make, and doing something that massive for each camera would mean I'll be sleeping an average of six minutes each day.
Gary Friedman you should create a video tutorial and sell them just like you do with ebooks... dvd style or downloadable vids.
Have you checked out my video tutorial which goes beyond cameras and talks about how to take pictures that make people say, "Wow!"? Check it out: www.friedmanarchives.com/seminars/
@@FriedmanArchives you should be one of the teachers on Creative Live for Sony gear.
@@garyfriedman2005 hahaI I have no pull / connections with them, but you could try.
Hi Gary thank you for your vídeo! One question if you allow me... When you use Lock-on for a person walking towards you or the left or right, the square will lock-on focus on that person, but what about the Eye detection, doesn't it work on this mode? If I'm on f/1.4 for instance and if I have lock-on will it focus on what part of the person is closer to the camera and the Eye will be out-of-focus? Thank you so much! I have a Sony a7iii and am feeling frustrated a bit because I don't understand something. The other day I went to shoot my first fashion event and lost so many photos because I couldn't focus when they were moving and I quickly went through all of them throughout the shooting... Would you please help me?
Hi, Anna. I'll be happy to help if I can. Please email me at Gary at Friedman Archives dot com.
does this apply to sony rx1r ii?
Very informative. I have a A6000 and just purchased the Sony G 70-350 lens for wildlife. Auto focus single point is providing varying results in poor light. What focus mode would you recommend?.. Many thanks
Low light and low contrast is a formula for autofocus failure. Depending on the animal you're focusing on you might be helped by making the focusing area a little wider (increase the chances of it seeing contrast).
Is the horizontal contrast issue still applies to todays cameras and updates ? .. because I was testing my 100-400 GM for back focusing issue with A7r IVA and I printed an A4 with horizontal lines, the paper wasn’t vertical it was tilted about 30 degrees ..didn’t have any issue to acquire focus.
Mirrorless cameras don't exhibit backfocus symptoms because the phase detect array is baked into the actual sensor, so it's not possible that the two would be out of alignment. And yes, turning the paper 30 degrees is enough to have the horizontal lines recognized.
@@FriedmanArchives if I understand you correctly you’re saying the camera doesn’t back focus .and I’m talking about the lens itself that might have the problem, I see many people in the Forums and CZcams videos talking about their lenses back/ front focusing. Thanks Gary
@@Hsukhaybir There's no way a mirrorless camera would confirm focus if the contrast or phase detect array didn't confirm it, so I'm not sure how a defective lens would cause the camera to confirm focus if it wasn't so.
When using the movable spot focus, how can it be re-centered quickly? I find everytime I use it, the next shot is not focused where I want it, and it's a pain to move the spot around.
@@garyfriedman2005 Hi Gary, thanks for your straightforward, and informative, videos. BTW pressing the trash can button should re-centralise the focus spot.
is the horizontal vs vertical focusing issue similar in the canon cameras?
@@garyfriedman2005 thanks, I've just discovered your videos and they are really helpful. I noticed you don't have too many Canon camera videos, is Sony your favorite?
Gary Friedman I had the eos r...it’s the same thing.
@@garyfriedman2005 the only camera i know is Olympuus EM1 II and newer EM1 X
What is the white vertical stripe on the left side of the screen?
@@garyfriedman2005 I have the A7R3 and I see the stripe as well. And I bought your book on the A7R3 long ago, do you explain it in that book too? Where?
I had the same question
@@sjsphotog Meanwhile I found out myself: it is a buffer indication, is shows how many frames you can still shoot in a row before the camera starts hiccupping.

HELP!.All my A Mount screw driven MINOLTA lenses do not work on my sony a7/3 camera with either the sony lea/3 or 4 adopter.....WHY?......NOTE: All my A Mount sony, sigma and tamron screw driven lenses work perfectly when i attach the lea/3 adopter to my a7/3 camera, they do not work when i use the lea/4.......i was to understand that all A mount lenses are attachable to the a7/3 camera by using either the sony lea/3 or 4 adopter, however i have found this not to be. true as i have explained the Minolta lenses, they only work on sony A mount cameras, period...CAN YOU TELL ME WHERE I AM WRONG ? THANK YOU .........I NOW FIND THE SONY LEA/4 ADOPTER USELESS, IS THIS TRUE?
All of your Minolta lenses should work with the LA-EA4 adapter. The fact that they don't infers that something might be wrong with the adapter.
thank you, I will return to Beach Camera@@FriedmanArchives
