This comment is based on use of the SF20 with M6.

I find it convenient enough with the M6 Normal and MP, though, the 
flash will switch to standby (ie, go off) after 3 minutes and then not 
fire when you press the M6's shutter, as the M6 cannot wake it up like 
the M6TTL can.  This has been a problem for me and I lost a number of 
shots because of it.  Now I tend to remember to check if the flash is 
awake and press a  button if it isnt.

On A mode with the SF20, flash compensation is only available in full 
EV steps, ie, -1, -2 etc.  With TTL capability it is adjustable in 1/3 
steps.  Nevertheless, I've found the SF20 to be very useful with non 
TTL bodies.  It has A mode pre-set apertures of 2.8, 5.6 and 11, so 
getting to f2 while shooting at 5.6 is just a matter of setting the 
flash aperture at 2.8 and dialing in -1 EV adjustment.  Works a charm.

Hopefully some of the the above is relevant to the SF24!
