BTW, these aperture series are fantastic -- I learned some time ago (mostly from you) that lenses are the investment, and real-world tests like yours show me which give the 3D feel and pop I prefer.
DIGLLOYD: agreed, they are highly instructive in terms of sharpness, contrast, bokeh and behavior across the aperture range. Which is why I do a lot of them.
Plus these two, both at 27 megapixels as 5 X 4 crop from full frame A7R sensor:
This scene explores sharpness and subject separation wide open vs stopped down.
This scene explores image circle and field curvature at distance focus.
This APS-C crop explores how much real depth of field is gained with stopping down. Depth of field is not at all like calculations; it depends on actual lens performance.
