50/f2.0 Heliar compared to 50/f1.5 Nokton

[Yoricko]

How is the 50 / ƒ2.0 Heliar compared with the 50 / ƒ1.5 Nokton in terms of cost, IQ and built?

Someone offered to trade his 50 / f2 for my 50 / f1.5 . I don't really need the wide aperture and I don't like the biggy size of the Nokton too.

Opinions?

The build quality of the Heliar is excellent. It won't take up much less room: one, it does not retract much; and two, its hood is designed to be kept mounted.
