I'm not going to vote on the cameras, because none of them were exciting enough for me to consider.  The 85 1.4 L IS is on my shopping list, very excited about it.

I readily admit that my grasp of optical physics is limited.  I read this forum to alleviate that.  Thank you for your informative although sometimes sarcastic posts.

The greater the focal length of a lens, the more it magnifies. Keeping object distance the same, a telephoto lens renders it larger than a wideangle lens. This much should be obvious. But it also directly follows that if you want to render an object the same size with a wideangle as with a telephoto, you need to decrease the object distance. To get a 1:1 magnification with a 35mm lens then obviously requires a shorter focusing distance than with, say, a 100mm lens.

The distance between object and image plane is four times the focal length if you have a 1:1 reproduction of the object if a single lens element is used. (e.g. 35mm lens - 140mm distance / 100mm lens - 400mm distance)

Complex lens designs use some tricks to do 1:1 like reducing the focal length a little bit for closer focus distances to get the 1:1 reproduction ratio with less travel/material. But if you look at the second table in the following link from Bryan Carnathans web page - https://www.the-digital-picture.com/Reviews/Canon-EF-S-60mm-f-2.8-Macro-USM-Lens-Review.aspx - you see that the MFD is roughly twice the MWorkingD with some exceptions.
Most used tools: EOS 200D + EF-S 60mm + 4.0 / 70-200 IS AND/OR EOS 5D i  + 4.0 70-200 IS + 2.8 100 Macro

The 6DII is my worst camera of the past few years. As a 6D owner I was early awaiting an upgrade but it really isn't much of one and in many ways is a step back. Such a shame.

In what way/s is the 6D II a step back? I know it scores slightly lower DR at ISO 100 but is there anything else?

Yeah, touchscreen + DPAF + 6 more MP + 2.5 more fps + 34 more AF points + NFC / Bluetooth make photography worse for everyone.  Total step backward.   ::)
