Title: 35 SLR lenses on 16 cameras
Post by: private witt on January 27, 2009, 08:34:50 PM
Anybody rig up a 35mm SLR lens onto a 16 or S16 camera?  How much did the converter cost you?  Problems with vinetteing?

Only type of converter I've used was a Letus 35mm Extreme with a Sony EX1:

Results looked great, although I ended up with some grain issues and it's tricky to properly backfocus.  Manufacturer said this was because of the prism possibly beign misaligned...not sure if a 16 to 35 adapter might have similar problems.

Suffice to say 35mm make a big difference and are worth the investment.

With 35mm adapters you are getting 35mm depth of field but not resolution -- that's a big difference right there.

How would the lens effect resolution?  Wouldn't that still be determined by the grain of the film?

I believe that is what md means--the resolution is not increased by the lens.

Ahh, gotcha.  I wonder if there's people out there who actually think that a longer focal length somehow magically crams more information onto the negative?  'Course there's probably plenty of dumbshit things I have misconceptions about too, so I probably shouldn't poke fun.

Its not 16mm, but I once shot something with a Brevis and SLR lenses on a Panasonic HVX-200.  One lens, IIRC the 35mm, gave big headaches with vignetting.  They weren't the best lenses, though.  Racking focus during a shot can be difficult with SLR lenses (compared to cine 35mm lenses and a focus puller), and they tend to breathe if you do rack focus.

Thanks for the reply.

Yeah, I played around with a 35>HVX200 rig that poorly build, it was essentially a nightmare.  Flipped image, vignetting, lens didn't actually fit properly, ground glass didn't vibrate consistently.  The well made ones range from about $1,500 to $6,000.  Pretty much why I decided t'was better not to fake video as film and just use an ARRI.
