Purely for interest I have put a small folder on the internet to show the before and after when one of Mike's profiles is applied to the m4/3 Olympus 12-40 2.8 zoom.

The "a" is before and the "b" is with the profile. The lens is at the wide end of the zoom here.

On the camera it is a cracking good lens. It really knocks the spots off the kit zooms - but so it should at that price. What is fascinating is to see just how much correction the camera has to do when writing a jpg to the card.
