You focus when you set up the shot. If you need dynamic focus each shutter trip, re-enable it on the shutter button for that session.

Not always an option...

BBF is still auto-focus — you are just using the button to choose the focus point. Manual focus is when you are turning the focus ring on your lens - something else altogether.

From my perspective (I have been using BBF on my personal and work Nikon & Fuji cameras for about 10 years now):

Advantages
- INSTANT switching between static focusing and continuous focusing (release the button, focus is locked, hold the button, focus tracks).
- Makes the half-shutter press available to be exposure-lock (which is how I set mine most of the time when I am in aperture priority mode).
- Makes me intentionally grip the camera (to put my thumb over the button), lending to better stability, as well as not accidentally hitting any of the several buttons that are in the vicinity of my thumb.
- You can pre-focus a shot, then hand someone else the camera to take the shot.
- You don’t have to worry about focus shift when doing repetitive work (say, copy-stand, impression work, or a production-line photo directory) every time you press the shutter.

Disadvantages
- You can’t hand your camera to anyone to take a shot without either pre-focusing for them, or explaining BBF.
- A split-second of “why isn’t it focusing” when you use someone else’s camera.

I’m sure your camera manual will tell you how to enable BBF (though it may not call it that!), if someone from the forum hasn’t already given you the step-by-step...

I love it. My primary recreational shooting buddy hates it. Give it a try. If you like it, go with it. If not, nobody’s feelings are going to get hurt - I promise! :)

This is the best I could get. I could not get a sharp focus to save my life. Super-cold here, too - I believe it was about 9 degrees farenheight. The angle was nearly straight up, too, so my tripod was wonky as all get out & I had to lay on the ground to get my eye behind the viewfinder.

All the more reason your blanket retort was so ridiculous to start with. Give it a rest.

And just where do you live?

Again, you speak from a position of ignorance. You are wrong on both counts here. I would suggest you take care to learn some law before you put yourself into a situation that might cost you great sums of money or your freedom.

The behavior outlined in the “story” would establish probable cause in any court of law. DUID is Driving Under the Influence of Drugs — something that would be confirmed or denied by the blood test. No false arrest here at all. You should study some case law before you make such equivocal statements.

That’s making the assumption none of the others got caught. If they did, then you could add a conspiracy charge to the both of them.

I don’t know about where you live, but around here they tend to stack several deep at the problem “watering holes” come closing time...

The charge would be DUID until such time as the test came back negative. (Though at that point, he as already retained a lawyer and would still have to come to court to answer the charge.) At that point the prosecutor worth his salt would add obstruction, creating a public menace, misuse/abuse of emergency services, and whatever other charge might be applicable in his jurisdiction.

Like I said — it would be a VERY expensive prank.

Then it was a very expensive prank. Lawyer fees alone will cost him a couple grand...

Take him in for a blood draw and charge him with DUID.

My D810 came with the 24-120 “kit” lens. I love it. If I’m not packing a bag with extra lenses, that’s more than likely going to be the one lens that comes with me.

Nope.
