The 2nd aperture is not the principal thing that affects bokeh. It is the paired lens elements just after the aperture that has the main effect.

I've not tried the multi-channel triggering yet as I can only shoot myself at the moment Not very exciting, nor does it give much opportunity to experiment.

I looked at the Gadget Infinity demo video of the charity concert. Multi-channel triggering is great for that kind of set-up.

Gadget Infinity is a trading name of Harvest One HK Ltd.

I only have two flashes as well so multi channel is barely relevant. I guess I could add the AF160FC to the setup and have three...

Ooh, FISH!

I'll go cook some fish!

Perhaps you should try it some time. Then again if it is that or M&S then M&S wins.

I've not had dinner yet and you are making me hungry.

I'd better go cook something...

They are a joy to use. I was a bit worried about ordering from overseas as it can be difficult to gauge the company you are dealing with. It is hard enough with internet purchases in the same country.

I'd definitely say go for them if you can but you may end up getting lots more flashes. I am already tempted to get some Metz 36s just to have more light coverage in future.

Now this is a tough one but I have a couple of ideas. Not entirely sure the'll work in colour though I'll have to get creative.

Thanks again, that will be very good for keeping dust out. Now, just need one more for a second body.

You got that at a very good price on that lens!

Looks like fun, I'd have to Steam-punk up my camera if I went though.

That wouldn't be easy either...

I'm rather fond of Leeds, there are much worse places out there.
