I have an Olympus FL36 that I use with my Panasonic GH2 camera. I often hear that this flash is under powered and has horrible recycle times due to its puny two AA batteries. I’d like to say that this is not true if you know how to use the flash. The trick with this flash is to use it in AUTO mode, not TTL AUTO. With TTL AUTO, all the bad things people claim about the unit are true. With AUTO, though, it is a different deal. Last night I shot a party. Shooting distances were admittedly short, which saves power, but I was using a Peter Gregg bounce card, so some additional power was needed. The recycle time was negligible. I was essentially shooting burst mode at times with up to five shots and never getting a missed flash. By the end of the night I had shot 199 images and had three shots where the flash failed to fire or failed to get the exposure right – I think that’s pretty darn good. Also, after 199 shots the two Maha Immediaon AA batteries still showed to be in pretty good shape when I tested them before recharging them. I think they could have gone on for another 100 shots. The key is in using the AUTO mode, not TTL AUTO. TTL AUTO has a pre-flash that uses a lot of the charge and each flash essentially depletes the capacitor. AUTO mode does not use a pre-flash and therefore uses less of the capacitor’s energy. The difference is dramatic. The AUTO mode probably does not expose as precisely as AUTO TTL, but it is very good and handles all but the most radical situations very well. For using AUTO mode, put your camera in manual or aperture priority mode. I raised my ISO to 640 as the venue I was shooting was quite dark. In brighter venues I typically use 320 for flash photography. If your flash has both AUTO and TTL AUTO, check this out. AUTO mode will get you a lot more flash power, even from allegedly underpowered strobes.
