p.1 #1 · p.1 #1 · Elinchrom Zoom Head flash duration


I can't find any flash duration numbers for the new zoom heads.
Nothing in product guide/documentation. Google failed or user error
Hoping someone here would know.

All I have seen is super short 40-45% better flash duration compared to standard heads.

This is copy paste from Digital 1200 RX / Digital 2400 RX manual:

Flash Duration Digital 1200 RX / Digital 2400 RX
With 1 flashhead Digital S/SE 1/1200 1/600
2 flashheads Digital S/SE 1/1900 1/950
1 flashhead Digital type A 1/2200 1/1100
2 flashheads Digital type A 1/3400 1/1700

This seems quite correct for the Zoom heads too. Duration is more dependent of the power pack design than the heads. I can tell you that even 2 heads connected to 2400 RX results too long duration to stop even slight motion (for example portraits shot handheld). But it is not a fault, just specs. I am generally very happy with my units and their price-power-performance ratio.

Based on the data you posted the heads do make a difference even when using the same pack. The A heads draw more power and have shorter flash duration than the Digital heads.

Yes that is true, S and A heads have a significant difference in duration and also when two different type heads are connected to symmetric pack they draw power at different speed resulting in asymmetric output. But I meant that the quoted figures are for older model heads and the new zoom heads are probably the same if comparing A head figures to Zoom Action and S head figures to Zoom Pro or Zoom HD.

p.1 #7 · p.1 #7 · Elinchrom Zoom Head flash duration


Taken from a another thread I started in search for an answer.. Guy was nice enough to take the time out and do this.

(Zoom Pro HD head:
2400 J pack full power: t0.1 1/200 s
1200 J pack full power: t0.1 1/410 s

Zoom Action head:
2400 J pack full power: t0.1 1/415 s
1200 J pack full power: t0.1 1/725 s

Note that these are t0.1 times, not t0.5.
I calculated these flash durations using a Broncolor FCC meter.)

This is interesting information since I don't have any way to actually measure the duration. The figures from Elinchrom manual seem pretty reliable based on these measurements, because they are t0.5 and these are t0.1. Difference between the two figures matches approximation of t0.1 times being about 3 times longer than t0.5 times.

They took down a lot of the specs, but they can be found here:

(Combine the urls, FM parses this incorrectly.)
