all of the Canon flashes in March of 2005 I decided to purchase
PZ40X AF electronic flash. I did not need a fancy flash
with a lot of functions and did not want to spend a great deal
of money purchasing the Canon OEM flashes. The Sunpak flash offered
the features I most needed...E-TTL compatibility and manual flash
settings. This flash is plenty powerful for macrophotography with
a guide number of 133' at ISO 100. The flash features manual power
settings from full power to 1/16th power in full f. stop increments.
I found the manual settings very useful for photographing shy
subjects, such a long-legged flies, that are disturbed by the
pre-flash of the E-TTL flash metering system.
of the flash includes an illuminated control/information panel,
distance scale for auto-flash, auto-flash confirmation, and a
red autofocus assist light. The Sunpak PZ 40ex flash has a tilt
head with detents at 45°, 60°, 75°, and 90° but
the flash head cannot be swiveled. Zoom settings on the flash
head range from 24mm to 80mm.
is powered by 2 AA cell batteries. I only used rechargeable NiMh
batteries in my flash and received a fair number of flashes before
battery changes. Recycling times at full power were a little slow
but, used at macro distances, were adequately quick. All in all,
the flash functioned well the first few months of use.
