Are you referring to this image?
One can zoom in with the mouse scroll wheel.
I noticed that perhaps the hand on the chair is slightly out of the plane of 
But I think I can see what you mean in the face.

Thanks for the detailed explanation. I'm not hindered by the FF limit as I have 
yet to find a reason to go back to u43. However, I have one lens that is quite 
diminutive in LTM (m39), the Topcor-S 1:2 f=5cm. It is quite sharp stopped down 
and might be great for travel. I don't have a lot of samples but here are two:

https://photos.app.goo.gl/wS99F16N9hVuwkcu5 I think F6.3, or maybe not?, no 
sharpening done

Getting close to a LF look I have not thought about. Interesting question. Here 
is one person's attempt to recreate LF look:
Clearly not a portable solution :-)

With large format, an F2.5 lens might be equivalent to an F0.7 lens on smaller 
format? Or some such ratio? antithetical as you say.
