Try a better way to focus your DSLR! Using back button autofocus is a faster, easier, smarter way to get great AF results from your DSLR. This video will show you how AF modes work - and why decoupling autofocus from your shutter release can take your photography to a whole new level.

This method works both for camera with a dedicated AF-ON button or by reassigning a button on the back of your camera for autofocus.

Questions? See THIS PAGE:

NOTE #1: With newer Nikon cameras, VR activates when you press the Af-On button, with older models, it only activates with a half press of the shutter release.

NOTE #2: In order for this to work properly on a Nikon, you need to have your AF Priority Selection custom function set to "release", not to "focus". That is the default behavior for AF-C, so most won't have an issue. However, if your camera isn't firing when you focus, recompose, and shoot, that's probably why.

All this and more is contained in a great download pdf book by Steve in his latest book 'Secrets To The Nikon Autofocus System'. I've reached a part in the book were I'm nudged to this link to watch as back up what Steve has expertly written. You cannot ask for more customer 'focused" (pun intended) top class guidance by this well respected professional photographer. Thanks so much!

Every camera guy on YouTube tries to cover this concept... But here is one of the best explanations I have ever seen. Thanks, good show!

FINALLY! After watching a bunch of tutorial about Back Button Autofocus, I finally understood how it works. Thumbs up to you sir!! Many many thanks!!

I just wanted to commend you on your excellent tutorial . I'm a street photographer who lives in Panama trying to photograph some of this country's 900 species of birds and your tutorial made a difference. I knew it was going to be good when you didn't start off with "Hi Guys".

This is by far the best explanation of back-button focus I've had the pleasure of watching. It was clear, simple and a joy to listen to. Thank you so very much Steve.

[MrYungComedy]

This is by far the best video that actually allowed me to understand what back focus is and how it works! Thank you so much!

I didn’t know about this until just now watching Steve’s video. I can’t wait to set this up on my camera and use it. One great explanation on how it works and how to set it up.

I am a pure beginner. This was the very first video on Auto-focus I watched, 2-3 months ago. The comments of others prompted me to purchase the ebook. After becoming fairly proficient with Steve's explanation and shooting hundreds of photos while practicing, I thought I'd try out the "old" method, just for the sake of knowing how. Holy Molly! I couldn't wrap my head around this half-click mode, switching between S and C modes, and trying to keep it all straight. Why isn't what Steve recommends the default way of shooting, is beyond me. Best 30 bucks I spent in this new hobby. (I'm in Canada so the book costs a little more.) Thank you Steve, the rest of your videos are on my to-view list. Great instructor!

There are tons of videos out there, on Back Button AF, and this one nailed it! With apt examples.

[parsleylion]

this is (in my opinion) a fabulous video. Why? very good diction, very clear, very positive, (rehearsed?) concise, to the point, no waffle, no er, um,   or other repetitions, good eye contact. It is well lit, well framed and you stand out against the background. Treating the viewer with respect, not condescending. Well done Steve, I enjoyed watching this, and of course, I have learnt a lot. Thankyou.

Thank you Mr. Perry! I bought your book Secrets To The Nikon Autofocus System last night and am now getting my head wrapped around the auto focus on a few of my Nikon cameras. Your information delivery system is concise and easy to follow. My new best friend is the BBAF. Good job
