Profoto Acute 2 vs Acute Acute 2R

Thomas Beaman , Sep 23, 2007; 05:30 p.m.

So I have finally decided to make a lighting upgrade. I am going with the Profoto Acute 2 system. I recently read something from a user who recommended not getting the new R version with the built in slave becasue he said if that little gizmo breaks, you need to send the entire unit in to be fixed. But with the regular Acute 2 version you would only need to send in the slave piece. My questions is to all the Profoto users. Which do you recommend if you were buying one of the 2 systems right now. And I know that there are other systems out there but I have decided to go with one of these so please keep your suggestions to the acute 2 or the acute 2r....thanks so much. Thomas

Sorry for the typo in the title

I'd get the Acute 2R. I've used various LPA Design Pocketwizard remote triggering systems ( they make the receiver in the 2R pack) for about 10 years now, and except for the time a stage hand plugged the sync cord from a receiver into a live electrical circuit instead of the strobe he was supposed to plug it into I've had zero troubles with them.

Thanks alot Ellis. I appreciate the fast response Thomas

I'm in the same boat as you are. Acute vs Acute 2R. I was told via a seller that if the antenna does break it (antenna) can be bought and shipped with out having to ship the power pack to the repair clinic. I was told the above from an ebay seller who was selling an acute 2R with heads a few weeks ago. He said he bought the antenna new (as his broke...) from the "Camera Clinic" in NY. I'd call your local Sammy's camera dealer to see what they say as confirmation.

Flash Clinic not Camera Clinic...

the external antenna is very much a user replacable part -- it just screws on and off. depending on the physical circumstances it is always necessary for the system to work. The D4 has the antenna contained with in the pack. The biggest flaw I see in either an Acute 2 or the Acute2R is the very long t0.1 flash duration at full power with the standard Acute2/D4 head: 1/70th second according to my tests. t0.1 is the flash duration you want to know if you are interested in two things:

1.) the ability of the flash to stop motion at a specific power setting.

2.) It dictates the shortest shutter speed you'll need to set the camera to in order to get full light output to the film or sensor. With a t0.1 flash duration of 1/70th second at full power, you'll needto set the camera to 1/60th of a second (maybe 1/80th). Anything shorter than that (like 1/125th) will clip the flash exposure.

How much either of these things will bother you is up to you.

In the Profoto line I much prefer the (more expensive) D4 and Pro7A.

BTW, Ellis, any idea when / where we'll be able to enjoy the full fruits of your recent light- testing labors? :)

Looking forward to it!

Ellis, I had no idea of this. So am I understanding it correctly? If I shoot with an Acute 2 system at full power....I can't shoot faster than 1/60th? If I am understanding it right, I might be rethinking my purchase. Please let me know if I have that right Thanks Thomas

I just checked with Profoto's site and they claim that the flash duration is 1/320 sec @ max power. But Ellis tested it at 1/70th of a second. How can a huge company like Profoto get away with bumping the numbers like that? Now I am back to square one on picking a system. The Acute 2r sounded perfect but if the full power flash duration is 1/70th or a second, that is just not acceptable for something that is so expensive.......ok...back to the drawing board
