I have taken quite a few recently with MF lenses, (Konica etc, etc).
BUT, I now always seem to find that the dedicated AF lenses perform better - 80% of the time - (or maybe it could be my eyes!)
This shot was taken with the "I can do anything star" - the Panasonic 20mm f1.7
It was quite windy so the shot is at 1/4000 sec and ISO 400 @ f1.7
Colour, taken as a jpeg, maybe was more to do with the light - the shot was taken towards the end of the day in France.
Colour, also, taken with a G1 - the EP1 usually performs better on the "colour front" but maybe the G1 likes "red"
I increased the "presence" i.e. vibrance and saturation a small amount in LR
