Brilliant. Thanks Paul! That's over twice as much as the B400/X1600 can do at 8fps.

The faster recycle per WS and the IGBT technology are responsible for the difference. I was very happy with what I got.

"I then repeated the test at 8fps and 40WS (1/16 power) and fired a 12 shot burst. I got 12 recycle beeps and each shot is identical in exposure (within 1/20f) and color was exactly the same for each shot. A lot of fun - So, yes, Einstein is a speed demon in this use, and dead accurate."

Excellent!; thank you, Paul, for performing this test.

Yes this is wonderful news. It opens up many doors for high speed shutter/flash applications from the Einstein. Thanks Paul.

Paul,

I have been an extremely satisfied customer for over 25 years and I'm on your wait list for four Einsteinís. Currently I own four X1600's and have successfully synced them up to 1/3200 sec. using the new Pocket Wizardís TT5 on my Canon 5Dmk2. Really neat!

Do you think I will be able to get those same results on the Einsteinís, or will there be an issue with the peak times on them?

Thanks and keep up the great work!

You should still be able to do this with with Einstein in some form. But you won't get the ability for motor drive shooting just described because you will have to use a relatively high power setting, then throw most of the power away.

Depending on how tweakable they are, I'm not sure how well they'd work. The older bees generally had more flash duration unless you're firing the Einstein at full power. Definitely post when you get them since you're going to be a guinea pig

Paul,

Do you have any feel for how even the light from the Einstein will be without a modifier? In other words, will the Pyrex dome over the flashtube help eliminate any hotspots, or would it still be comparable to what the Alien Bees lights put out?

Thanks!

No comparison. Einstein dome completely eliminates hot spots - with or without reflectors, and what you see with modeling lamp is exactly what you get with flash. The modeling lamp with AB/WL is somewhat forward of the flashtube (same with most other monolights), and the diffuser makes the flash and model look identical.Lights that use bare 250Q lamps (RX600 and others) have really bad hot/coldspots and anomalies when used with high gain reflectors.

what fstop do you get with and without the pyrex dome?

In the Einstein manual, the claim in "no light loss" caused by the dome. As soon as mine comes in I'll independently test that. But I suspect that if any it will likely less than 0.1 stop. Metering and exposures will tell the full story.

The same.

Very glad to hear the Einstein will fire before full charge. While commercial work is a bit more forgiving, weddings benefit greatly as an almost properly exposed amazing moment is better than a perfectly exposed moment of blah.

just out of curiousity...has anyone heard of an update on Einstein?

Last update on the PCB tech forum was that the run of the first 100 was being made this week.

What became of the batch of 12 from last week?

I hope the 12 got put into the pre-order mix because according to PCB, they were "perfect".

They work perfectly, but are no longer new . . . they have been beat to pieces and been through torture testing with zero failures. The first real 100 are being built right now and have to be assembled and tested. Another 4000 are going into production right behind them.

So I'm guessing at least another month or two before we actually see these out in the field?
