Hensel / Elinchrom RingFlash

A friend has the Eli one on order .....

As far as the 2 ring flashes designed for the quadra the biggest differences seem to be flash duration

ECO is 1/1000s on the A channel and 1/2500s on the B channel
PRO is 1/1950s on the A channel and 1/4500s on the B channel

so freezing some action with the ECO at full power could be an issue.

To add to the above, that's because the ECO uses a 2-pole flash tube while the "pro" flashring uses a 4-pole flash tube.

1/1000 on A port is still quite fast, maybe not to freeze fast moving objects but fast enough for most people work I imagine. There has really been only few times when I think the A heads were better than having S heads for my Quadra.

When only one flash duration is given, it's usually the t.5 flash duration, so the t.1 flash duration would really be 1/333 which isn't all that fast.

I know, but 1/333 is not that bad. I mean most of the time shooting people who don't run away from me will not need more than that.

The 580exII also has 1/1000 (or at least google say so) at full power and its is not bad at all.

According to the spec list on Adorama.

Flash duration at full power t 0.5 - t 0.1
Plug A: 1/1000 - 1/500
Plug B: 1/2500 - 1/1200

Flash duration at min. power t 0.5 - t 0.1
Plug A: 1/600 - 1/300
Plug B: 1/1400 - 1/800

It is also about half the weight of the PRO with the ECO coming in at 2.2lbs

I've used the ECO ring flash on a Quadra and it's not bad, noticeably lighter than the RF1500 from elinchrom and the included diffuser cover is nice. The cons is that I don't own Quadra system so wouldn't ever own the ECO and no aftermarket modifiers. The pros is that it's so light I can hold it all up with one hand

Simon, did you get a chance to use one yet?

Thinking about keeping my Quadra for use with a ring flash and had the Eco in mind, but I still haven't read about anyone except ed having used it (or buying it for that matter).
Does anyone know how it compares to the RF1500 in terms of build quality? Judging from pictures it seems to be pretty much the same except for the handle? Is it possible to use the Hensel Sun Haze on the Eco?

The weight difference is much due to the lack of a permanent cable. The "old" RF1500 ringflash is made by hensel (hence why their modifiers work on it) the new Eco ringflash is a different design, it has a smaller flashtube and thus the overall size of the unit is slightly smaller (approx 1cm in diameter) it also lacks a handle.

I think it's a great unit for those who want to use a RF on the quadra, it's lighter, more mobile (think transport without cable and handle) and quite inexpensive.

Dennis, FWIW i wouldn't use the Sunhaze without a handle like on the RF1500. You wouldn't have any way of balancing it in your hands. Granted i haven't used the ECO, but it seems like you'd have to hold it in your hands directly.

However, the Hensel standard reflector for ringflash would probably work quite nicely.

I doubt the Hensel accessories work on the ECO since it's smaller. The handle is certainly mandatory if your gonna use a modifier like the sunhaze, it would be near impossible to wield without it.

I dunno, i think that despite the smaller size in front, i think the mounting points may be the same. But then you'd have to deal with the reflector insides not fitting as well. Hmm. Yeah maybe it won't fit. I don't know anyone with an ECO RF to test it out... does anyone in the US have one?

Thanks guys. Just wasn't sure as I hadn't seen either model live.
I'm not gonna bother with the RF1500 just to keep my Quadra. Might as well buy the (cheaper!) Profoto ring flash.
