Elena Sorre Posted December 7, 2005 Share Posted December 7, 2005 I'm going to try out some Vision 500 film in my old GAF S805 super 8 sound camera but the film says to use with "high speed" cameras. Are there "high speed" super 8 cameras? I've only used Ektachrome and Kodachrome before. Any advice or help? Elena Link to comment Share on other sites More sharing options...

At 24 fps many super 8 cameras expose the film at *about* 1/90th of a second. I suggest using a hand held meter and using an ASA between EI 250 and EI 500. Then use the aperature that your meter gives you at a 90th (or what ever shutter fits the fps you are using with your GAF.... hope this helps, Steve Link to comment Share on other sites More sharing options...
Premium Member John Pytlak RIP Posted December 9, 2005 Premium Member Share Posted December 9, 2005 At 24 fps many super 8 cameras expose the film at *about* 1/90th of a second. Steve Are you sure about that? That would be a relatively narrow shutter angle of only 96 degrees. :huh: Link to comment Share on other sites More sharing options...
Guest santo Posted December 9, 2005 Share Posted December 9, 2005 The only super 8 camera that comes close to that is the Beaulieu 4008 as a "normal" setting. Some people complain it's got a slightly strobe look to the footage when the camera is moved. I'm not sure what the exact number is off-hand. All the rest are 1/60 - 1/50 range for non-xl cameras and in the 1/40 - 1/30 range for nice and blurry motion xl cameras. I would think that the "high speed" label only refers to cameras which can read the high speed film notches. 500 being a high speed film and having a longer notch than the other film carts like K40 (a slow film speed) and Ektachrome (a medium speed film). Some super 8 cameras can't. I have no idea if the Gaf model described can. Wish I could tell you, Elena. Link to comment Share on other sites More sharing options...
Premium Member steve hyde Posted December 9, 2005 Premium Member Share Posted December 9, 2005 Are you sure about that? That would be a relatively narrow shutter angle of only 96 degrees. :huh: Thanks John - My B4008 - which is a new camera for me - shoots at 90th of a second at 24 fps. That is information from the camera user manual (not in front of me at the moment) The Beaulieu 4008 is not a variable shutter angle camera. My estimate that *many* super 8 cameras record at *about* a 90th at 24fps is not based on empirical evidence. That is why I suggest checking the specs on the camera in question. My advice, in this case, is mostly conceptual: 1) figure out the approximate shutter speed of the camera. 2) meter for an aperature at an ASA between 250 and 500 with a fixed shutter speed 3) if it's a daylight shoot don't forget to compensate for 85 filtration 4) with 7218 err on the side of overexposure.

Sam Wells Posted December 9, 2005 Share Posted December 9, 2005 That 1/90 second shutter speed really surprises me too. (Are they selling the "Private Ryan Look" as a feature ?) Seriously are you sure this isn't like the old Bolex so called "adapted shutter speed ?" where a "1/80" shutter speed was given for ~ 1/65 actual shutter spped so as to give allowance for light loss in the camera's beam splitting prism ? It wouldn't surprise me at all the reflex optics in a S8 (excluding Beaulieu mirror-shutter etc) would eat up 1/3 stop and I'd expect more (the very reason the XL models were introduced). It's been too many years since I owned an S8 camera, but the Nizo Special (really an S-56) I had - probably lost ~ 1/2 stop. -Sam Link to comment Share on other sites More sharing options...
S8 Booster Posted December 9, 2005 Share Posted December 9, 2005 (edited) got to be a mis-interpresting in the first place; "only for cameras accepting high speed films" (either in manual or auto mode) from 1 of my old posts on filmshooting.com That said, I've had some great fun with the variable shutter on my Beaulieu 4008 -- you can get some incredibly edgy motion with the lens wide open and a reduced shutter 'angle' (never know how to word that with a guillotine mechanism).. usually referred to as half open and you may well use a degrees equivalent shutter angle/speed: s/hoot Edited December 9, 2005 by S8 Booster Link to comment Share on other sites More sharing options...
Guest christoph Posted December 9, 2005 Share Posted December 9, 2005 (edited) the beaulies dont use a prism, but a gillotine shutter (goes up and down) so one cant really talk of shutter angle... but 100% of the light hits the film when the shutter is open (well, actually something like 99% or so, since there is a built in clear filter that is engaged if you switch off the 85).. it's the only super8 camera that has no light loss due to a prism (and the only one with true ground glass) the 4008 series has a shutter speed of 1/86 sec at 24fps, the 5008 has 1/60 sec at 24fps, the 6008-9008 have two settings, LL at 1/60 and normal at 1/96. hope that clears things up ++ christoph ++ Edited December 9, 2005 by christoph Link to comment Share on other sites More sharing options...
Premium Member steve hyde Posted December 10, 2005 Premium Member Share Posted December 10, 2005 (edited) Great table! Wow - there is far more variance than I assumed among different cameras. Thanks for clearing this up for us. Thanks for posting it. edit: I'm surprised the Canon 1014XLS runs at 1/39th !?!? That does not sound correct to me. No wonder some of these cameras produce such soft images.... Steve Edited December 10, 2005 by steve hyde Link to comment Share on other sites More sharing options...

When set to 150° shutter speed is 1/58 sec. david Link to comment Share on other sites More sharing options...
Leo Anthony Vale Posted December 10, 2005 Share Posted December 10, 2005 the beaulies dont use a prism, but a gillotine shutter (goes up and down) so one cant really talk of shutter angle... but 100% of the light hits the film when the shutter is open (well, actually something like 99% or so, since there is a built in clear filter that is engaged if you switch off the 85).. it's the only super8 camera that has no light loss due to a prism (and the only one with true ground glass) the 4008 series has a shutter speed of 1/86 sec at 24fps, the 5008 has 1/60 sec at 24fps, the 6008-9008 have two settings, LL at 1/60 and normal at 1/96. hope that clears things up ++ christoph ++ ---the guillotine is the reflex mirror not the actual shutter. The quillotine swings into place when the shutter is closed , and out before the shutter opens. This set up will give you more light to the viewfinder. The eclair ACL has a similar set up. BNCRs and Panaflexes have seperate variable angle camera shutters and rotating reflex mirror shutters. ---LV Link to comment Share on other sites More sharing options...
