This reminds me of the approach to this topic that my some-time deceased
professional (Forest Research) friend Harold Heimke-Hemming would have
adopted.
Mount an ?80mm (or whatever - I don't have a 'Blad) lens on his Hasselblad,
get back far enough that everything required was tack sharp at, say f/8, take
the shot, then later crop out the unwanted stuff ... :-)
Simple, quick, and excellent results !!
