POTN Aussie Club #8 - Einsteins won't make you smart

You would use the 134 Ws output with a high-speed head to give you an incredibly fast flash.

I think !!!

Austen.

Or to give you an even lower power setting than you could hope for.

Austen - straight from the Quadra manual:

The system offers two Ranger Quadra Heads with LED Pilotlight:
• The S Head is designed for universal photography equipped with a standard omega
plug-in flashtube
• The A Head offers a very short flash duration for action freezing photography. The new A tube is a
single twin pole plug-in flash tube also with even light distribution

Ranger Quadra offer a 66% for outlet A and 33% for outlet B (2:1) asymmetrical light distribution with
two connected RQ Heads.
66% for outlet A and 33% for outlet B
Outlet A: 25 ws – 400 ws (one connected RQ Head) - gives maximum power
Outlet B: 8.2 ws – 132 ws (one connected RQ Head) – gives shortest flash durations
Outlet A & B: 66% A, 34% B for asymmetric light distribution of power 25 ws – 400 ws

...ps you can download the manuals from Elinchrom's website which also shows you how feature rich they are.

Mic/Al... get those credit cards ready. Tell 'em I said if you were in Sydney Suresh from Kayell would have looked after you ; - )

I don't think I have to worry too much

hello fellow aussie POTNers.
im selling some camera gear, check out my thread.
if you are interested just PM me.
Thanx

Nice prices. I'd be all over the Sigma 10-20 if I had an APS-C camera

Since the topic refers to Einstein - any physics people here? I was reading an article in NewScientist and it got me thinking. E=mc^2 Suppose that c isn't the limit but that E is. This wouldn't change the speed of light, but would allow lighter objects to travel faster. Could this allow for such things as quantum entanglement, without breaking Relativity?

My thinking is thus. At the moment of the big bang the most energetic level any particle would be capable of would be E. E=mc^2, so the speed of light would be governed by c= (Em)^-2. Thus, quarks, bosons. et al, being lighter, would be capable of super c velocities. Would, could, this explain "spooky interaction at a distance"? Allowing for entropy, could this conflict with the current belief that the universe is expanding faster than we postulated? After all, the speed of the galaxies we see expanding is measured based on an earlier, faster c. Perhaps this may explain why we can't find all that dark matter.

Interesting hypothesis which now has the question....Does dark matter really exist?

It works down to 12.5mm!

It looks better on APS-H by MILES!

be interesting to see what you think of them.
they are INCREDIBLY small and light.

Yeah, I'm interested too. But I still don't think they'll work for me, or that I can afford them.

Cool, i see why they are calling the two ports asymmetrical now, though makes me think even more that the best/most versatile option would be to have 1 pack per head.

Yeah, which makes them whacky expensive.

Good Lord! Are you lot still going on about lighting?!?!?

shouldn't that be c=(E/m)^-2

Only where K^c¾√3 < 1
