Thanks, the Steve Perry video was excellent. I have a better understanding now!

"With AF-C you don't have the option to get a focus lock then re-compose. AF-S gives you the option to re-compose after achieving focus lock on an object that's at the desired distance."

Just a point of interest,the D500 allows lock/re-compose in AF-C. I realize your specifics were for the D750.

Of course you can re-compose in AF-C after getting focus!

We were discussing using AF-C with release mode. Back button focus lock seemed to be an unnecessary complication to the discussion.

Are you talking about more Steve Perry videos? Or others? I do like the way he explains things.

Steve mentions back button focus lock on the linked video. It can be used to override AF-C in release mode.

When you are shooting sports and wildlife and using the camera's fast burst rate, you would rather get a shot than possibly miss it because the camera does not see something in focus. Also, if your subject happens to move off the focus sensor and you end up focusing on the back or foreground, you may end up with a perfectly out of focus main subject.

What a lot of photographers do is remove the focus capture from the shutter release and move it to a button on the rear, usually the AF-On button. This makes image capture independent of focus all the time. Together with leaving the camera in AF-C mode, you have focus on demand, and you decide when you want it or not.

You can press the AF-On button to acquire focus and release it, then recompose and press the shutter. Or you can track a bird in flight with the AF-On button pressed all the time while you press the shutter. This gives you the best of both worlds, and eliminates missing shots because you forgot to reset the camera from AF-S to AF-C or vice versa.

Good morning,Gene.

Very good explanation!

I understand the BBF function,but my remark regarding the D500 was that in AF-C mode,with the shutter pressed halfway,you press an additional sub-selector button that locks both focus and exposure,thus allowing you to re-compose. Definitely not the same function because I believe it would be for stills.

The first thing I do with a new camera is set it to release when I hit the shutter button. That's what the button is for. I'd rather have a shot that's less than perfect rather than none at all. The next thing I do is make sure it won't activate the shutter if there's no SD card inside.

I like it on release as well. That way,if I doze off I don't need as much reaction time if startled when awakened. :roll: :roll:

Good morning,Jerry!

We have been three times since retirement in 2011 and spent about 40 nights there. Two to three hundred shots per day in quite normal and the price is right! Sorting through them is indeed reliving the trips and we continue to enjoy them. We found it very worthwhile to learn some of the history,geology and geography as well as the wildlife. Going back one more time next year!

Any particular time of year to try and avoid the crowds. I had a reservation for the end of June but decided to re-think it for next year ... Maybe late fall?

End of June? Not for me. Bus tours and campers fill up everything and add to the bison car jams.

After Labor Day and in the spring up until June 10 or so.

Much before Memorial Day and a lot of snow,road openings could be delayed. The big benefit is the new babies.

After Labor Day and many of the Park facilities start closing and pushing towards the middle of October can lead to snow issues as well.

We're probably going back in around October 1 next year,so that means making in-park hotel reservations next month. We're partial to the north end and Lamar Valley,so the Mammoth Hotel works well for us. Plus Gardiner offers groceries,food,etc. The little stretch between Mammoth and Gardiner usually offers Big Horn and the other guys as well.

Where it really comes in handy is when you use Back Button Focusing. If on AF-S and you press the button, it focuses on whatever point you are using and stays there whether you release the button or not. If on AF-C you can focus on your subject by pressing and releasing the Back Button and it will remain in focus for re-composing. If you hold the back button in AF-C it will continue to focus on whatever the focus point is on, which is great for moving objects.

I'm a sports shooter. I set my AFC on release priority and AFS on focus priority. Works well for me. Best of luck.
