Symbol on my camera, what is it?

What does the circle with a straight line symbol mean that's on my camera?

That shows you where the sensor plane sits, or film on film cameras. Useful to know distances from sensor to subject

Yes, specially in macro!

Thank you, but why would that be useful?

By that statement, you are demonstrating how little you know about macro. When DOF in macro may only be a matter of millimeters, precise focus is essential.

Yep, that's why I posted the question.  I don't know much about photography in whole.  I'm working on learning, but find there is a lot to take in.  So one foot at a time.

What I don't understand, if you are speaking of precision.  How is this seemingly random placed symbol going to contribute to precision?  

Thank you for taking the time to help me understand this.

Meant in the days to localise the film plane. it means now to
show the position of the sensor sensible plane.

Crucial and critical information when it come to evaluate real-
tive DoF given the focusing distance and the chosen aperture.

One would measure the distance from that mark to their subject. Using a depth of field calculator to determine the depth of focus so that the subject is within that area...

There's also a thing called a nodal slide which you can use to position the sensor directly over the axis of rotation. That symbol helps you align, and avoid parallax.

Why? There is a school of thought that says this is critical for accurately creating panoramas from multiple shots.

If one is close to one's subject, isn't the DoF so small (even at f/14 or tighter) that the computation doesn't really matter? And if one is reasonably far away (3-5 feet, say) that accuracy becomes less critical?

Given that you take lots of photos of tiny critters, would you mind elaborating a bit on methodology? I'd appreciate having a better understanding.

Surprising statement!

The only thing I consider with panorama is that
the lens nodal point IS at the axis of rotation; the
sensor has nothing to do with it!

I was mistaken. Not caring one whit about "perfect" panoramas, I've not bothered to learn about them, and I should have done my research before posting.

Ah, well. I readily admit to being incorrect when facts are presented, or at least googled.

At least one site I found discusses the "entry pupil" as the rotation point for the camera, but wants $13 for a book. Others point out that the nodal point changes from lens to lens. Lots of interesting information out there.

I'd fix the post above if I could.

Correct, a nodal point is very lens specific… each its own and
not always easy to spot. I suggest my students to mark their
located points for future reference.

Correct again, the non editing feature in a thread is a real pain
in the ass.

I, as a moderator, have that ability. Maybe bring it up in the support and suggestions forum.
