That you now no other accessories with special connection to the OM-D can use, because there lies the Mini flash it, you can get over, because except one probably an additional EVF to look purely from the top, makes the rest with lightning eh no sense ,
By the way you can use both lightning (the Shell and the FL-300) independently of one another in manual or TTL mode, and even switch the Shell "OFF". In "OFF" it sends Although the timing flashes, but not flashing into the picture. 's Just fun to experiment with it.
Perfect also the weight and size to be "always with you" and there is a fold-lightning foot on the on the table put etc or also be mounted on a tripod, as with built-in tripod mount (standard screw) and allesfuermich Ideal insects to snap flowers in the field.
Here is the miniaturization (for the price) but also a great weakness: all plastic. Although pleasantly shaped, but the battery cover has this stupid folding sliding shutter as it is common in many cheap devices. And after the second battery change is promptly the mechanism broke down and I'm determined not Grobmotoriker! A tiny plastic hooks of less than a millimeter in size is aborted. Very annoying! This could have been solved as a designer certainly better. Now can the trade no longer close and the batteries have no more contact. I hope that this is an exception here is a material error and have written to Olympus. Let's see what the reply. I hope I get replaced the flash, because I want to give him another chance - he is otherwise perfect for my purposes and wanted eigtl me even a second buy ....
EDIT: So Olympus writes, I will address myself to Amazon. I did that and immediately receive a replacement unit. Great service from Amazon! I hope the battery compartment lock in the new device keeps better; will be super careful now.
PS: And another note: I was the first try out the new device pretty scared that the flash does not turn on, despite fresh batteries and laaaangem pressing the On button. Then again controls the polarity, which is a bit difficult because the little picture that illustrates the correct position or orientation of AAA cells, is glued quite deep into the dark battery compartment; there's only a flashlight and best Leselupe! (Or user, but who is out and about ...). But all new reverse polarity of the cells did not help! The moral of the story was then that the flash is forced off, as long as one has the practical (extra) Lightning Foot collapsed. As long as you can press the On button as you want. It was only when the foot was slightly folded (there are several locking positions), "surrrrrrr" and the charging lights sparkled joyfully towards me. Actually very practical switch-mechanism, because if you know it in advance ....
