For those interested, below is a scan of the field curvature characteristics of the LLL replica from their documentation. I've taken it, turned it 90˚CCW, duplicated it, flipped it and then placed the two side by side to represent the full image circle.
The third image is a 'focus peaking' simulation of my lens at f/4 (using Find Edges filter in PS to modify a photo of gravel).
And the MTF curves:
Edit: below is a gif showing field curvature and focus shift characteristics:
