16mm Time Lapse

Post by deVere » Tue Dec 21, 2010 10:44 am

I'm looking to purchase a 16mm time-lapse system for a Bolex H16 Rex 5 but a bit unsure as to all the kit I'll need. I think:

Camera (have)
Tobin TTL (a good unit?)
External battery unit (Any recommendations? Do these have mains adapters as well? How long do these typically last run off battery power?)

Am I missing anything here?

Thanks.

the tobin unit is very well engineered. That, and a battery is all you need. I simply use a sealed lead acid battery I bought from an electronics shop. How long it lasts will depend on the amperage of the battery. Even though the circuit is on all the time, it doesn't use a lot of power.

thanks Richard. Do you know if the 'long exposure' function is controllable or simply dependent on the fps you set the system to?

hello deVere,
the long exposure mode on the tobin simply works by leaving the shutter open, rather than closed, every time it advances the film. The result being that the exposure time will be the same as whatever interval time you have set the contraption to. If you have set it to 60 seconds, ie. take one picture every 60 seconds, then the long exposure time will be 60 seconds (actually 59 seconds as the shutter is closed for about 1 second while the film advances). If you set it to 15 seconds, you would have a 14 second long exposure, etc., etc..
cheers,
richard
