RE: Eclair Cameras: Shooting 35mm lenses on 16mm camera-response



Hi Eric - Because the 16mm format is so much smaller than 35mm stills, it's a given that you'll see a telephoto effect when you adapt 35mm still lenses to your 16mm movie camera. For example, a 50mm "normal" lens for your Nikon will become a 50mm "telephoto" lens on your Beaulieu because you're just capturing a small rectangle within the circular image projected by the lens. The good news here is that you're using the highest performing part of of the lens - the "sweet spot" in the center.

What I'd like to know is how these lenses compare to regular primes, like the Schneiders and Zeiss lenses. Of course, you know that everything intended for stills work will cover Super 16 with room to spare. I'm wondering how my 17mm Tamron might work as a slightly wide angle.

This also, of course, means that finding a good wide angle of 10 or 12mm is a problem - there's the cosina/voigtlander 12mm lens in Leica thread mount but it's maximum aperture is f5.6 - not really useful for S16 work. I guess for a really wide lens one just has to use one of the lenses intended for S16.

raymond,

i have used a couple of cheap, older nikon lenses a couple months back using a nikon to c-mount adapter on my super8 and 16mm beaulieu cameras. i also used some other mounts for other 35mm still lenses, again, cheap lenses i borrowed from soem of my friends here that have still 35mm cameras in their closets. i do not personally own any of these still 35mm lenses. but the film, upon receivng it back from processing and telecine, looked good. mind you, i had only shot a couple thousand feet of film prior to those specific experiments, and was using differnat/various cameras for which i was neither accostumed to, nor had completely dialed in. but i did make sure is was in focus by zooming the lenses, setting to infinity, and opening hte iris all the way and then i focussed the viewfinder so everythign was clear/in focus, and then i adjusted the lens down to 5', and used a tape measure to check if i was in focus at 5', and i was for the most part with the differnat lensessome i could not focus below 10-15'.. so after doing this i filmed both indoors and outdoors using my colorbar slate, and i used the range of the lens(es) and aside from some improperly exposed film(due to my lack of experience), all the footage came out great. however, everything seemed like i was using a 2x adapter on one of my normal c-mount lenses ... everything was more like a telephoto lens, wherein the subject was in focus, but anything behind or in front was not. this was at close distances. i did not shot much footage otherwise, wherein everything in frame was in focus, but i did shoot a little, and indeed everything in frame was in focus when the lens was opened wide, not zoomed. but the actual frame/image still looked like i was using a telephoto. perhaps i am not explaning this correctly ... do you know what i am trying to say? am i making sense to anyone?

i will upload these tests once i get my computer apple setup. perhaps then you wll understand what i am saying. i think that if one were to use 35mm still lenses on 16mm cameras, they just need to know things will seemed magnified and seemingly zoomed, even when the lens is not.
