Back Button Focus, my first attempts...
Dec 29, 2020 13:01:16 #
Tried BBF for the first time today.
My local park has some Ring-Billed Gulls that I thought would be good to try it out on.
I took around 60 photo's of them, and out of those 60, I would say I probably had roughly 50 that I would consider to be keeper's.
Here are two from those that I took today. I, myself think these came out rather well.
Used my Sigma 70-200mm lens for these, and yes they are cropped also.
My settings were as follows...
1/3200 sec.
F.11
ISO 1000, I was in auto ISO, with a low of 400 and max at 2000.
I also want to give a shout out to CHG__CANON and also to amfoto1 for giving me some headway on how to use BBF.
So far I like it, but having used it for only about an hour so far, I'm going to have to do more practice with it for sure.

Focus look great!
I tried using single, group, and 25 point.
I found that group seemed like it worked the best, at least for these.
I didnt like single at all.
Does that sound about right to you?
Again thanks for your help.

A single point is very difficult to keep on a moving bird. It can be done for a bird predicted to soar / glide / fly in a relatively straight line and speed. Not so much for gulls.
You might consider a slower shutter to bring down the shutter. I think you'd get the same frozen look at 1/2000 sec.

Keep at it, Tom. Once you get used to it you won't go back. Nice first attempt.

Whether fixed or AUTO, you don't need 1/3200 to freeze a gull. Being unnecessarily fast on the shutter just serves to be unnecessarily high on the ISO.

I love it! Never going back.
(And it keeps focus and exposure separate.)

Just remember it takes a bit to get used to focusing with a different button.
After a while it will be second nature.
Then again, I don't do moving birds.
