Nicholas,

I agree that oatmeal type grain can occur with certain combinations, but why the fine results with TMY-2 and not with Delta 100, considering the similar technology employed? I will check against TMX. The lens was the 150mm, hand held in reasonably calm conditions, bright but hazy, on the summit of a hill. Hand held use can affect sharpness and acutance but shouldn't influence grain I'd have thought.
