I've never looked through a MK4 (based on the above) but I have looked through a MK2 and my MK 3 side by side, pretty unscientific but the MK3 looked slightly clearer and colours had more clarity - had I been smarter I would have been checking to see if they both came back to the same place on range-finding which would have been far more useful!
Yup, thats a Mk3.
I've never seen the fabled 4th version though, got any pics?
