I am 76 plus. I do Fine Art photography for artists, usually oil paintings. Stability of subject is not an issue, think heavy wooden, oversized easel with weights. Lighting is everything. But the competing claptrap in this series on pixels, resolution, sensor size, coloration, vividness, saturation, dpi, make of camera, stabilization, print size, monitor screen size, etc., of comments is interesting, but not nearly as informative as the DPREVIEW video referred to below. You will not regret watching and learning from it.

Let me note that weight, as in astronomy telescopes, and industrial microscopes is EVERYTHING to prohibit NOISE, from jitter, breathing,wind, ground shudder - from people walking, elevators, etc., etc.
I cannot do handheld, and wouldn't even try. In fact I built a HEAVY tripod, with modifications to "pin" the camera, the monitor, the flash, and the microphone (for video comment to artist), to the horizontal bar with 1/4" stainless steel bolts through the 1.25" thin wall tubing. The tripod is the Benro Mach 3, the video head is the Benro S6 Pro. Why video head? Because I can move via one handle, all of the items pinned to the horizontal bar at ON TIME in up/down/left/right axes, and thus center the frame exactly where I want it to be. Of course auto focusing on my Nikon Z6ii is at first auto, then manual (always; because on larger (wider/taller) works the dead center focus point has to be adjusted because of lighting variations on the work (oils reflect differently because their surface texture and heights, reflection, are different all over the piece). Fun? Huh?
I shoot 14bit raw, 600dpi, I print 16bit, 600dpi, on Canon Pro 10 or 1000. The biggest challenge to receive client approval is coloration - they mixed them in minute detail, my job is to mirror it.
