I used hot shoe mounted Metz48 with a flash softbox (the ones that you can find on ebay)
IIRC, at f16, I might have seen some diffraction, but I'm not so sure, since it could have been movement too. Finding out what works and what does not is quite a work in progress I afraid.
I'm quite convinced that the setup is capable of pretty sharp shots, based on indoor test of static stuff. (even 100% crop is astounding with macros of stuff like dollar notes and text prints).
On 3-dimensional stuff, and outdoors, perhaps DOF (or the lack of) and discomfort messes with what can be achieved.
I'd still say that a 50% crop can be done out of these shots and still make decent photos out of them.
My current setup :
Q+F100/2.8 macro+hotshoe flash+diffuser+LCD loupe
Mounted on tripod
Fire off with 2s timer (whether on full tripod or tripod assisted hand hold)
f8 and make sure the ambient light does not contribute to the picture (to eliminate camera shake)
The LCD loupe and tripod makes a big difference to focus and stability, imo.
Hope that helps.
I guess I was just lucky with the subjects.
They weren't moving, but I think the equivalent 550mm macro setup also meant that I did not need to get as close as I'd have to on APS-C.
I was not aiming for 1:1 (~30cm).
