DA18-135 @f8

M100 @f8

Do you think they are both as sharp. I manually focused with LV x 10 on the wrinkle on RHS of RH eye

Very close. The DA lens may have the edge, but that could be a difference in colouring that's deceiving the eye.

The slight difference in density does deceive the eye. Very hard to say which is which at this resolution.
Best regards, John

Studying the wood grain, I would say that the DA 18-35, has a slight edge, but it is only slight.

Take care.

The DA 18-135 has slightly better contrast, which I think gives an illusion of greater sharpness.

I great test, if I have time, I might repeat with my 18-135 and D FA 100 Macro WR.
