Right after Christmas I posed a thread, Flash Photography, about some issues I was having with a GH2 and an FL36 flash. The take-away from that experience was that the camera and flash combination worked best with the camera in full manual mode with baseline settings of roughly ISO640, f2.8 and 1/100 of a second. The flash should be put in the AUTO mode (not TTL-AUTO), which provides good exposure control and very fast flash cycling, much better than TTL-AUTO.
Yesterday I was messing around with some old 50mm primes and making comparisons between them. Because it was at night, I used the flash. Well guess what? When using a non-intelligent lens, the flash will not allow you to use AUTO mode. Normally there are five options available; TTL-AUTO, AUTO, MANUAL, FP TTL-AUTO and FP-AUTO. This is what I get with either my Panasonic 20mm or 14-140mm lens. However, with any of the primes on m4/3 adaptors the available modes drop to TTL-AUTO and MANUAL.
According to the FL-36 manual, pages 34-35, with a manual camera the flash should work in AUTO and MANUAL modes only. In AUTO mode you set the ISO and f-stop of the camera into the flash and the flash will figure out the rest. In my case, with a half-smart camera, itís working a bit differently. One would think that with the camera set to manual exposure, the camera flash control would be disabled and the flash would work as with a fully manual camera, but apparently not.
There may be a setting deep in the menus to fix this, but I was unable to find it. Perhaps a hot shoe adapter, passing only the trigger signal, could be used. Has anyone had any similar experience to pass along regarding this? Having taken the time to figure out what settings work best with the flash, it would be nice to be able to actually use them with my favorite prime; still the Takumar 50mm f1.4.
