Ah! I have had some issues with the guns facing in towards white brollies but none on silver ones...

I have used some bits of old silver paper/plastic to reflect the command light to the sensor. On the 50Rs they can be turned right round to point towards the command flash.

However, I tend to use a radio trigger and Manual Mode everything. The one huge advantage of controlling lights from the camera, is when they are placed out of reach or behind white backdrops, etc..

Yeah. You need to look at the Cactus V6II, allowing you to adjust the power output etc.

Or...
Go over to a Godox system, and have much better integration. Especially as it gives you full control over TTL or manual settings

Indeed! If I was starting from scratch, I'd go that way too. But I have 3 FL-50Rs, a FL-36R and lots of old T20 guns & stuff...

Plus my knowledge is firmly based on Manual mode and Flash Meter.

The Cactus V6II would work fine with all those, except the T20

Re: Inconsistent remote control of flash guns...

Having laid it all out again, it was definitely user error in the location of the flash units in relation to the commander AND a lack of instruction book reading

The flash units were probably to close to the camera to get reliable communications - the instruction book suggests an angle of 50degrees or so for the flash to be in front of the camera to give clear line of sight for the light based commands, while I wasn't at 90degrees it wasn't far off...

I'm going to use Mikes excellent tutorial to try and see if I can make it all work more consistently I'll post the results (Mrs Walti permitting)

Re: Inconsistent remote control of flash guns...

The other little note I've found in the FL-36R instructions is that TTL only works in P mode with an E5, is this still true of the EM-1ii? - the camera manual suggests not.

I used Olympus T32 and T20 units, joined to each other, and to the hot shoe, by TTL cords, in manual mode (camera and flash). Where the magnification compensation factor did not take effect, I used the meter on the T32. Otherwise, I used calibrated settings for magnification, ISO and magnification combinations. This worked in the same way as incident light metering does for non-macro daylight exposure.

I think what it is saying is that P mode will allow for aperture & shutter variation to work with the TTL flash level, or Shutter Priority would do the same if set to say 1/250 sec (or longer), but if using Aperture Priority & stopped down to say f8 then it may end up being too dark for the available flash power. Whatever, your latest model cameras have greater sensitivity range with Auto ISO than the E-5 ever had.

As mentioned earlier, that angle of line of sight can be cheated if there is sufficient reflective area (within that 50 degree angle) to which the flash's sensor can be facing to pick up that reflection, but it can't be too far away from that reflected area & as I mentioned earlier. the commander flash signal can be set to High as well (& while having it set to Off for inclusion in the flash), but don't forget, commander flashes now have swivel heads & that angle can be shifted to suit your own setting.

I don't know if this helps but it works fully with the EM-1 (1) in manual mode with stopped-down manual lenses for macro. I use RC + TTL via LM-2. Shutter speed is usually 1/250 but it can be lower.

Macro is close & requires very little flash power whereas portrait type situations would take a lot more to light it as it depends on distance, surrounding colours & textures etc.

Actually, it requires a hell of a lot, due to very small effective apertures and the magnification factor. Sometimes ISO 400 is not high enough. I often have to wait for the guns to recycle.

Anyway, my point was about metering or not metering, not power output.
