Back Button Focusing

Oh my GOODNESS! I know Steph has said BBF is really great, but wow, I finally figured out how to do it (the setting isn't exactly intuitive on the camera!) and I took a bunch of shots today, and they are almost all tack sharp! I can't believe the difference. I don't know why it works so much better, but all I have to say is THANK YOU, Steph, for talking about how great it is. I don't know if I would've tried it otherwise!

Yay!! It's amazing how it can make that big of a difference, isn't it?

I seriously can't believe it, Steph! I mean, I'm not terrible with my focus or anything, but it's like it just takes it up a whole other notch!

I'm so psyched, I just have to share some of the 'tests' I did today! Smile

Oh my! GREAT!

Where can I find this info on BBF? My focus has been so horrible lately!!!! I use my 50mm a lot and it is good if I am up close, but man...pretty bad from far away.

What camera do you have? I had to google how to do it on mine. I'm sure it's in the manual, but I would have had no idea where to look if I wouldn't have googled it first.

Awesome, Tracy! Looks great!

I found the info for my 60D here: Back Button Focusing on the 60D - Canon Digital Photography Forums

Oh, I found directions for the Rebel XS... see if this works:

"What you want is on the manual page 158. Custom Function Settings. C.Fn-9 Shutter/AE lock button.
Change this to 3: AE/AF, no AE lock.

"You can now focus using the * button and shoot using the front."

That looks right to me, Tracy, for my XTi. Must be the same on the XS.

Ya, it took me a while to figure it out on mine, but I too LOVE it. Thanks Steph!

Oh my, thanks for sharing! I'm really excited to try this out on my Canon now. Very sharp, Tracy!

I wonder if Nikons are as good in that department. Must check for my D7000. Thanks for the tip, ladies Biggrin

ETA: Here's a guy who has a couple walkthroughs for different Nikons Back Button Focusing – Easier than you think!

Suzanne, I actually hear that Nikon has the better focusing system in general. Canon's been developing the video function, while Nikon has been developing their focusing system. There's one pro photographer that I love who recently switched everything she had from Canon over to Nikon to get better focus! I can't even imagine how much that cost!

Awesome, Stephanie! I really like to hear that. I only wish I had my camera here with me now to go ahead and set it up.

So....I thought I was back button focusing, but I wasn't! omg... Anyway, I'm slightly confused. Do you hit the * button and then the shutter button? Or do you press the shutter halfway down and then the * button and then take the picture. I played around with it a little today, but couldn't figure out the correct way.

You hit the * button and then the shutter Smile The awesome thing is, you can take pictures even faster because you don't have to refocus every time you take a picture. That is, if you or your subject doesn't move Wink

Steph's instructions are right. But you do have to make sure your camera is set up for it (see earlier posts), which was my previous mistake. I tried it without setting the camera properly and could not figure out why it didn't work! :O

I LOVE BB focus! OMG!! My focus button is the 'AF-on' button, btw, on C-Fn. 3. It works just as well for me with that button so I may just keep it. Wink
