Sorry, I don't know.

Practically none. Both are spec'ed with a minimum field size
of 48x72mm (1.9x2.8in).

50mm F2: 0.24m, 50mm F3.5: 0.23m. The difference must be due to
the longer construction of the f2 version.

If weight is important I'd take the f3.5, as it only weighs
200g. The f2 weighs 320g.

I have had a f3.5 for many years and I am very pleased with it.
It is very sharp and has low flare.
