A significant one, if the birds were in fairly strong light. While
you'd have to have been synching at 1/60th, they could have been
at 1/250th, thus buying further reach from the flash, and in the case of
some birds hovering or in any kind of motion, more image sharpness.
It's one of the major shortcomings of the OM line.
If you look at the NIkon & Canon line-up, you'll see that there
are inexpensive amateur cameras with much pro potential. The way
the manufacturers draw lines of demarcation for marketing to pros
is via the synch speed. Most amateur cameras go to 1/125th. Most pro
units jump to 1/250th. Of course, max fill-flash range isn't of
importance to everybody.
