Yeah, these things get bandied about willy nilly. To compare 2 lenses with
respect to resolution and contrast you need to consult the MTF curves for each
lens.
If you do this you can determine:
1. For a specified resolution (e.g. 40lp/mm) which lens has the higher contrast.
2. For a specified contrast (e.g. 50%) which lens has the higher resolution.
It makes little sense to say lens A is a high contrast lens while lens B is a
high
resolution lens.
