As I said, yes indeed the 35mm is an excellent macro lens for the price. I have taken many close up insect and wasp shots with it, and the results are imho quite good.
As for the 50mm... well this is what Olympus class as semi-pro glass as opposed to 'kit' glass. It is probably twice the price if not more than the 35mm equivalent, but does yield much crisper and brighter images. The macro is only 1:2 whereas the 35mm is 1:1, but it is f2 and fast!
Zuiko glass IS quality glass... that's a fact and I doubt many here would disagree with me on that.
