Today I moved the crabapple blossoms indoors out of the wind. Using the
Canon 5D I shot a bunch of photos using the Vivitar Macro Focusing
Teleconverter at 1:5, 1:3, 1:2 and 1:1 with the OM Zuiko 50/1.4, Zuiko
50/1.8 and Zuiko macro 50/3.5. I shot the full range of apertures on
the 50/1.4 but only used f/8 on the other two for comparisons.
The bottom line is that there isn't a hill of beans between the 3 lenses
(at least at f/8). I didn't compare beyond f/8 due to diffraction.
There's little difference to be seen on the f/1.4 shots at f/11 and f/16
vs. f/8. I think diffraction is taking away any increase in DOF.
This is what they look like. Pardon the creases in the "sky". It's a
blue shirt that wasn't large enough to get further away for better
blurring. I'm tempted to clean up the "sky" in PhotoShop but, nah,
never mind.

Any differences between these lenses is more than totally swamped by my
errors in refocusing after changing lenses. I should have added a large
crop of the 1:1 image. There's much more detail showing there than I
ever saw with my eye.
