Now it's time for "As long a review of the Sony HVL-f45rm flash as a wedding photographer time for in October!"
Good: It's freaking magical -- why is it so tiny, so well-balanced with small Sony cameras, with such little meaningful power difference? If I'm rocking a reception with a big flash at 1/8th power, on the tiny 45rm I'm *maybe* at 1/8th + 1/3rd, a negligible difference. Here it's hitting ISO 100 f/11 at well under full power, balancing the bright sun outside and highlighting how bad-ass Denise is. And it's the best TTL I've ever used, so good that … I even use it occasionally.
The bad: Weirdly fragile, in my experience. We are fairly good to our gear these days, and out of the four Sony flashes we own, four have been to the repair shop for hot shoe issues. Now we pack it as gently as we would a newborn kitten.
