Hi I get from second hand a cinematography intervalometer
http://www.cinematog...ex_gallery.html

I plan to use with Arri 35-3 (180 degree shutter) and Arri SR2 S16
Someone knows the exposure time with this device to calculate the T stop (for 180 degree) ? maybe 1/20 sec.?

thanks in advance

Andres,

I was looking at that same Intervalometer a few months ago for my Arriflex IIC with Cinematography Electronics crystal motor base.

Send them an email and they will send you a PDF of the instructions for the Intervolometer. The question about shutter speed you are looking for is covered in the instructions.

It's been a few months since I looked at it, but IIRC the shutter speed was somewhere around 1/3 of a second, but I can't remember for sure.

Also IIRC there was some issue with using that intervalometer with certain cameras. You have to buy some other part (a Single Frame Kit) to use the intervalometer with certain cameras, check the web site for details, but I think the two cameras you mentioned, the Arriflex 16SRII and the Arriflex 35-3 both need that extra part.

Best,
-Tim

Thanks Tim, you´re right Arri 35-3 and SR2 need a single frame kit. I have a 35-3 that comes with it and i do not test the intervalometer with SR2 yet.
I think that is not the same item because it comes with a camera package, I don´t know the seller that you say. If someone can send me the manual or simply tell me the exposure time I will be very apreciated, thanks

Andres,

I just found the PDF on my computer. I put it up on a web site I own, but I will only leave it up there for 24 hours. I do not own the copyright on the material and there is no way to ask permission to post it because the company is closed for the weekend. So it will be there until Saturday evening, Chicago time. Then I am taking it down. If you want it, download it soon.

Best,
-Tim

Thanks a lot Tim for your support.
I own the same intervalometer as the pic.
I found that the exposure time with Arri Sr and Arri 35-3 (with 180 degree shutter) is 1/3 sec.

Thanks again.
