Excellent!!

I had two FA28-70 both with fogged rear elements. One got utterly disassembled just to see, and the other is now destined for butchering. Mwahaha.

(Just not sure when exactly :roll

A five year old thread....

(Changed Title from "also for ale- 12-24!" )

From an initial look I reckon there are a couple of things going on.
First, there is a fair amount of uncorrected CA that is causing a bright edge. It is green/purple and LR has done most of it, but not all.
Secondly, it looks like rain pouring down from the top of the tower producing a feint darker band either side.

It is also possible that the stacks of filters have added to the issue, but it looks mostly like CA at 10mm.

Will look in more detail tomorrow...

And a little bit more info...

If the AF360 is set to say, 1/16 and Slave 2 (ie dumb mode) then it will work with the MX-1 on Slow Trailing Curtain Sync at shutter speeds of 1/45 and slower.

It seems the AF360 needs just over 20ms to be ready for the next shot - so with this slower configuration you'll get double flash from the AF360 (so it should be ok up to around 1/4 power)

It's not ideal, but it does work.

Best approach would be to use an optical slave trigger that will trigger only on the second pulse of light that is between, say, 15 and 100ms apart from the first - that algorithm will ignore the optional red-eye automatically (if you get my meaning!)... I can feel a hacker-project coming on

Matt

Update: the preflash and main flash of the MX-1 are about 22ms apart
Matt

It's no problem. You set the flash to "A" or "M" (not slaved) and use the cube to trigger it. The flash knows nothing - thinks it's being triggered from an old camera

There is. It's just very quick.

(Just need to lay my hands on a photodiode and I'll rig it up to our storage scope...)

The AF540 & AF360 trigger off the first (pre) flash, so that the flash is off in the actual exposure. Unfortunately these only have dumb-mode "fire on first received flash" or the complex P-TTL (which isn't done by the MX-1).

The SYK-5 cube should just delay the firing of the main flash so the slave contributes to the shot (but of course won't be metered).

HTH,
Matt

One of these SYK-5 cubes might be interesting... allows ignoring the preflash.

(Probably equivalent to the Godox "S2" setting in the chart above)

Matt

Very enjoyable set! Thanks for sharing
...nice to see the DA12-24 put to very good use too.
Matt

Steve,
Useful info
Is the switch choosing the pulse to trigger on?
Ie S1 is first, S2 is second etc
Thanks,
Matt
