More testing

Clear cold bright morning here in Sydney so compared the 40mm setting on 12-40/2.8 - 35-100/2.8 - and  the 45/1.8 all at f/5.6 aimed at some buildings 2.4km distant and also at some power pylons somewhat further away.

With 100% view at the camera jpegs I really can see no difference in detail, all look the same apart from my earlier comment that the 12-40/2.8 delivers slightly, only slightly, less contrast compared to the other two tested.

So my conclusion has to be that your 12-40/2.8 has a problem, or there is some user error creeping in.

Regards..... Guy
