I I guess that I have been lucky up til now! I am also quite surprised that a lens with new HD coating would be less contrasty than the old DA 21 and 25 Ltds without the HD coating.

Some of the lenses I had trouble with shot fine on my DS2, but it only has 6MP.

Different conditions make us notice different flaws.

A badly decentred lens or one with other flaws will often  not give its best contrast.

I have seen a poor report on the lens somewhere.

HD coatings are designed more to stop flare, I believe.  Other things, including the accuracy of the lens elements, contribute to contrast.
