err CB The Canon system does that also, well the 5D MKII did. you connect the camera to the PC via the USB Cable and follow the on-screen instructions, or you can use the memory card technique. Personally I prefer the memory card technique, anything that takes extra devices out of the update process is good news. regardless its good to have the new firmware on the card should there be an interruption of the re-flash process.
Does the Olympus SW not ask you to put an empty memory card in the card slot. I hope they are not running real time from the PC or from RAM.
I obviously didn't notice that. Trying to think if I upgraded the firmware on the 5D II. Pretty sure I did.

Works a little like windows updates John, downloads to memory in full before it alters the camera.
My old Canon 300D firmware did not work like this so it must be pretty new, Olympus has updated like this since the E1.
We are getting off topic, but I was thinking the PC puts the update into non-volatile memory so on a power interruption or task interruption you can re-start the process. So on the camera I would hope the new firmware is put into the memory card and not sent down the USB link real time as the USB link is prone to corruptions (and PCs tend to go off and do other things too) that may prevent the real time stream of data needed to keep the on-micro flash re-programming happy.
All the canon system does is run the code to the memory card from the PC, then the PC software guides you to start the camera re-program. My phone looks to use a similar process to update its OS. My tablet looks to have multiple memory devices so it downloads to one Flash device then runs from that to program the firmware.
How about the Sigma 19mm CB.

Would you be likely to use ISO 6400 a great deal CB, as I understand it, this is were the banding shows.
That Sigma focuses pretty close as well, 20cm, the same as the 19mm that I use

The OM-D is camera which tempts you to use high ISO, Paul! Lol! (More so, anyway, than my old Canon 5D Mk II).
My need for a fast lens is a few weeks away yet so I can play a waiting game for now.
