Following on from comments about the new flash for the E-M5 Mk II, which will not work on any previous Olympus camera, it's not exactly the first example of such idiocy. The small FL-LM2 that comes with the E-M1, which draws power from the accessory port, will not work with the likes of the E-P2 which has an accessory port to power the VF-2. Oddly enough, the VF-2 works quite happily with the E-M1, not that it's actually necessary. I have no idea whether this applies across other models with the accessory port. However, it makes one wonder what rocket scientists and marketing wiz kids they have working at Olympus, such that they can't create simple compatibility and consistency when it comes to products such as accessories. What next? Can we expect the next hot shoe not to accept an FL-50 flash?
