All good images were shot Shutter Speed priority at 1/250s, between ISO 800 to 1600 (I had my auto max ISO set to 1600) and apertures were the max allowable at the focal length I was zoomed. So in other words with that shutter speed the max aperture was always chosen as the auto ISO had come in for correct (near enough) exposure.
The dilemma now seems to be which is actually the best mode for this situation, noting that there is a large lighting difference between the top and bottom position of the shots hence auto ISO.
a) If Aperture priority is used I can set it 1 stop under max which in theory is going to give better results from the lens but at the cost of increased ISO. Speed can be controlled by setting the minimum (I reckon 1/320) in the auto ISO.
b) If Shutter speed priority is used max aperture will always be chosen.
I'm starting to think using the 50mm 1.4 is the answer as Lex suggested so I can open up to around 2.8. Looking at the majority of good shots they were between 65 to 90mm.
I'm also thinking about the best focus mode, I was using AF-C dynamic 9 point but wondering if I should push up to 21 or 51 point.
