First Look at Profoto B1 500 AirTTL Battery Powered Monolight Flash

Hands-on experience with ProFoto B1 AirTTL strobe - at California's beach

What will happen if you marry E-TTL speedlite and a hi-end studio monolight?

Here is what came up from Sweden engineers  from ProFoto:

Profoto B1 500 AirTTL Battery Powered Monolight Flash
This is a quick shot we got in the studio – with B1 Air in “slave” mode: this is how ¬†cookies (in Russian they called “sushki”) were highlighted.

We got a pair of ProFoto B1 500 AirTTL Battery Powered Monolight Flash for a KelbyOne WorldWide photo walk (October, 11th – signup here), and this is my first experience with this amazing strobe.

this is not a comprehensive review, but a very first user experience I want to share with our readers. The whole review will be created after few weeks of shooting with Profoto B1 Рin and out the studio.

  1. Hi! Did you use Ettl on the B1 to photograph the children on the beach? I’m undecided wether to get a Phottix Indra 500 or the B1, price of B1 has been putting me off. I wonder how these two would compare side by side in Ettl outdoors? I’ve searched YouTube for a comparison shootout but, nothing!

  2. HI Alex Do these B1 500 Air lights freeze splashes? Are they better than the Elinchrom Quadra ELB?
