the MK 320 works
superbly. I put it on the following cameras:
E-1 with Leica Vario 14-150 OIS
E-330 with Leica Vario 14-50 OIS
E-520 with 14-54
E-620 with 14-54 II
It meshed beautifully, and no - mine didn't show the ISO (and I had it in TTL), but the unit meshed superbly!!!
The thing is that with this flash (and
mine says "Lumix" by the way - not Olympus), the lighting potential (strength) belies its small size. I mean to say at ISO 400, f5.6 - 6.3, I can beautifully balance the lighting in a room that is 15 x 20. And for some reason, this flash does superbly on micro 4/3 cameras, in particular Olympus models. I also have this flash for the Fuji X system, yet there the strength (or implied throw weight) seems far less than what you get with the micro 4/3 and regular (older) 4/3 cameras can achieve. And again, keep in mind that Panny and Oly use the same TTL flash configurations and dedications so you can use either labeled Panny or Oly flash units.
I had the head tilted up at a 45-75 degree angle with the bounce cap (that came with it) attached. It is just uncanny how well this flash does.
I think I'm going to pick up another one or two of these for 4/3 and micro 4/3. Because I have so many older regular 4/3 and now micro 4/3 cameras, and with the cost being so low with this MK 320, it will be cost effective for me to pick up a few more. I'll never use the FL-36 again because I love the size of this MK-320, and it even seems to equal the throw weight of the Nissin Di-466 and other more expensive 3rd party models. Very interesting.
Here's the link to the MK320 flash page on eBay. Just fine the one you need for the right TTL dedication to your brand camera.

For Olympus/Panasonic (Lumix), here's a link to a good vendor who has tons of these:
