You got that in just 1/3rd of a second with F/32? I would have expected slower shutter.
 

Nice shot.

Correction--- shutter speeds was 1.3 sec, not 1/3 sec.  Just a typo :)

They make a 100mm f/4L Macro?

It seems I must have been asleep when I typed in the shooting info.... ::)   

Correct info is 7D with 100 f/2.8L macro, ISO 100, f/32, 1.3 sec.  Can view all this in EXIF info embedded in file.

The main point I was trying to make here was my desire for max DOF (f/32) and good IQ (ISO 100), which required somewhat long shutter speed (1.3 sec).  Fortunately, there was enough available light and no wind to do this. :)

Images start looking weird after f/16 usually in my opinion.  Was this just a test, or are you really trying to shoot around f/32 all the time?

More of test.  In hindsight, additional shots at wider apertures would have been instructive for comparison purposes.   Still, wider apertures would have lowered the DOF, which I wanted to maximize in this case.  Lots of detail in this tulip that I found interesting.  The DOF trade at some point becomes an artistic choice, even considering some optical distortion - and not an absolute necessity.  :)
