i scanned the negs anyway just now. stacked and aligned them in photoshop, then compared each to each in a table. i wish i could show the table in html so you could see more easily which was sharper and which tied. just remember that if two apertures have the same number of points, it means they tied when compared to each other. if one has less, it lost. i counted itself as one point, cuz at least you have the aperture (f1.4).
here are the results:
closeup, center
16 = 7 points
11 = 8
8 = 6
5.6 = 6
4 = 6
2.8 = 4
2 = 4
1.4 = 1
closeup, corner
16 = 7
11 = 8
8 = 6
5.6 = 5
4 = 4
2.8 = 3
2 = 2
1.4 = 1
infinity, center
16 = 4
11 = 8
8 = 8
5.6 = 8
4 = 8
2.8 = 4
2 = 2
1.4 = 1
infinity, corner
16 = 6
11 = 8
8 = 7
5.6 = 5
4 = 5
2.8 = 3
2 = 2
1.4 = 1
f1.4 isn't all that bad, actually. it may have lost in comparison, but closeup the center is almost as sharp as f11. it's very close. the corners are pretty blurry, though. f1.4 is distinctly lower contrast than f2 and up.
anyhow, i think for my next attempt, i'll use the hexar rf on aperture-priority.
