I just bought a flash package from B&H Photo consisting of two 580EX II flashes and an ST-E2 transmitter for controlling them off-camera. I thought it was strange that the “complete package” didn’t include something fairly important: The battery for the ST-E2. I can understand not including AA batteries which are fairly common, everybody has some of those lying around, but the ST-E2 requires a special lithium battery, called a 2CR5. The worst part is that B&H did not even warn me that this battery would need to be purchased separately. Boooo!
Sometimes you can use 2 AA batteries instead of 1 2cr5.
When I first opened the battery compartment my first instinct was that it was for AAs but I noticed there aren’t any conductors on one side, and it very specifically says it requires 6 volts, and two AAs would only give 3 even if I put a conductor in there to wire them in series. The compartment’s too short for AAs anyway.
let us know if there are any survivors at B&H Photo 😯
depending on the price paid, I’m fairly certain I would return to the point of sale and have a word or 2.
the worst that could happen is that you still wind up buying the battery, but you might get lucky under the
heading “customer service”….
