the only thing I know is that the Eclair Acl has a c mount and you can either buy adaptors for 35mm lenses or you just put a nice Angeniuex zoom on it.
Oh one more thing... in this forum you have to you use your real name , you can't you a nickname, so I bet if you change you display name people will respond more

I'd avoid tv lenses, you can find angenieux and schneider primes in c-mount for cheap, but better to stop them down to get it sharp, they are very small and don't accept normal follow focus gear.
The tv type lenses? Can you use those lenses on an ACL or CPR16? What are some cheaper options for lens? are there any cheap options?
For Angenieux Zooms the 12-120mm has a bad reputation, the 9.5-57mm has a good reputation and goes rather cheap on ebay, the 15-150mm was build for 1inch video TV and covers Super16...
I have the 12-120mm, I always avoided it because I don't like zooms and people say it's bad, but I actually never shot some test-charts so I can't say for sure. For the others it's just rumors I hear...
You can find Schneider and Zeiss Primes at reasonable prices for Arri standart mount, they're built to work with follow focus units...

P.S. I think I actually have one of those adaptable C-mount aadapters, and it is really cheap. Make sure you get a good one. Having your lens improperly adapted to the camera's film plane will hurt more than any spherical, chromatic, or barrel, or pincushion distortions ever will. EDIT: One more thing, there was a thread on this forum several months ago involving a 12-120 with either Vision 100T or Vision 200T and the results look as good as the footage I see from the 16mm TV shows (and no I don't mean "The Shield" ;-)

As someone who HAS shot tests with a 12-120, and little else at that :-( , it performs just fine. Shoot it at 5.6 or smaller and you'll be just fine. Even 4, I wouldn't worry too much.
I'll try this soon... thanks Karl
Did you ever shot a nightscene with the 12-120mm that has small bright lights in the frame, like carlights or streetlamps? I got some funny halos around each light, it looks rather nice (somehow strange), I never had it at this point with another lens...

One other thing, using a matte box will prevent ghosting caused by lightbulbs, natural lightsources, or candles from showing up on the film when they're not in frame, which is almost always an undesirable effect, unless you're shooting a shot across the desert.
