Modeling flash

Yes, customizable.

High speed sync

Yes, Sony claims up to 1/12000, although Sony doesn't have any cameras yet with a 1/12000 shutter speed, that's a carry-over from 1990s Minolta Maxxum (Dynax) 9 series film cameras.  Reality suggests HSS is available up to the maximum shutter speed of the camera.

Not supported by Sony.

13.0oz (369g) without batteries, 17.0oz (481g) with batteries.

Operating temp

0°-40°C,  32°-104°F


Works great with Radiopoppers™ triggers, without the set-up hassle of the Sony HVL-F42AM flash.
Has 'Ratio 2:1' flash indicator but this function isn't available, it's a carry-over from Minolta film cameras.
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.


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. 
Compatible with Sony's newest control flashes.

Good for


Not good for

A very small negative would be the 6 second full recharge rate, but that can be shortened with better batteries or an external battery pack.


Highly recommended, but not available new.  Replaced with HVL-F58AM in late 2008.
