Final comment from me for the moment.

I’ve just looked through all the exposures at all the apertures zoomed in 10X.

The Cooke 32mm Mini S4 is great at T2.8 to T8, softens a little at T11, softens more at T16 and is very soft at T22.

I’ll have to include this test in all future camera and lens tests, this si the first time I’ve had this chart in the centre of frame like this. It is there to show issues like the colour aliasing but I hadn’t though of it as a lens test 😊
