Quote: I reckon B is the OM lens. There seems to be little or no fringing on either but B is a touch sharper which I'd expect from a prime lens, even an old one...
Same here...I think B is the old lens but I haven't gone pixel peeping! I'm only going by the thuumbnails!! I think the colours in A look like they have come from a more modern lens for digital. The colours in pic B look drab in comparison.
