I need help with Elinchrom big octa and Profoto D1 500
1

Hi,

I just tested my new big octa last night. I order also the adapter for Profoto and went to shoot.

I notice that there is a dark spot in the center, the D1 is casting a shadow and making 1 stop differnce (lower) than any other place.

I can work the difference moving the model, but I have never seen a video or something like that.

Am I doing something wrong? Is because the Profoto D1 are larger that Elinchrom heads and then casting more shadows? Is there a fix?

I went to the website Elinchrom and they suggest to contact the local US dealers, I emailed Elinchrom US.

Have you guys experienced something like this?

Make sure you remove the built in reflector from the Elinchrom to Profoto adaptor. If that isn’t sufficient, then also remove the frosted glass plate from the D1 head and use a glass dome.

Should look like this...

It should look like this after removing the reflector

There are three very small Phillips head screws. Just remove the small ring reflector, you don’t need it, the D1s have there own built in reflectors. The screws and washers are small, be careful not to lose them; screw them back in after you take the reflector off.

Once you have removed the reflector, you can then slide the adaptor so that the frosted glass plate is flush with Elinchrom softbox. Removing the reflector will also allow you to use a glass dome, if you have one.

Thanks,

I just had time to remove the reflector from the speedring adapter this morning. I will try tonight when I get back from work.

I will keep posting. I hope this thread helps later somebody else.

I tested the big octa and the adapter without the reflector.

It always show a dark spot, but only if you are looking for it. If you don't know, you won't see it.

I meter the spot and it is only 2/10 stop darker in a small dark center than before.

I would say this fixed my problem.

Thanks, so much. I have 2 pictures that I placed in my Model Mayhem, one is the avatar and the next one is the same lady with a glass of wine. Amazing light.
My MM is 2621695. Check it out.

I am glad it worked out. I’m sure 0.2 stops will not be measurable from even a foot away.

I don’t know what to do with the ring reflector, perhaps you should keep it in case you ever try to sell the adaptor.

You are most welcome.

Two fixes from one post and none of the usual DPR contention, totally amazing.

Just type the number into the search by number box (MM#) at the top right.

Corrected instructions

If anyone has been following this thread, my instructions were based on something done a while back and weren’t quite correct. There are no Phillips head screws and washers, there are Phillips head bolts and hex nuts. Corrected instructions follow in case anyone searches for the topic at a later date:

To get the Elinchrom to Profoto adaptor to work fully with Profoto D1 monolights, you need to remove the reflector from the adaptor. The Elinchrom ring reflector isn’t needed with D1s, which have their own built in reflector, and it prevents mounting a diffusion dome and severely restricts modifier zooming.

You need to remove this:

There are three 2-3 cm long fine threaded Phillips head bolts with small hexagonal nuts. Remove the bolts with a small Phillips head screwdriver, being careful leave the nuts in place.

You can see the edge of one of the nuts in the center of the following image:

Once you remove the reflector, screw the bolts back into their holes, being careful to engage the nuts. (A small flat head screwdriver is useful here to keep the nuts in place – a very small open ended wrench would be better, but isn’t essential.)

It should look like the image below when finished:

Re: Corrected instructions

a very simple solution to use your profoto-heads with a Elinchrom EL Octa 190cm ...

just bye a profoto softbox ring at Calumet (for 20 dollar),

unscrew the top ring of the Octa, slide the soft box ring in the opening and screw the both back on to the Octa / Umbrella.
