Modeling flash option uses a custom 'test' button setting, so you have to change back and forth unless you want the modeling flash to go off every time you test fire the flash.

Flash will fire even if it isn't charged sufficiently, so check the charge indicator before shooting, otherwise you may wind up with the wrong exposure.  It does this so you won't miss a shot waiting for the flash to fully charge.
Bounce indicator shows only on downward bounce (8°), but not in any 'up' position.  It will show when the flash is swiveled.


Can be custom set for full manual use in all recording modes, even "auto."  Flash is automatically turned off when camera power is turned off, then back on if flash is still switched on.
Fully compatible out of the box with Radiopoppers™ flash triggers.

Good for

Almost everything. 

Not good for

A minor negative: Intense studio use, as there is no external battery pack input or cable connection like the F56AM or F58AM.


Highly recommended.  Replaced HVL-F42AM in early 2011.
