Any 35mm adapter for the hpx500 yet ?

I am waiting on one too. BTW, the P&S is ~$27k

I hear there are some options in the works though, but can't remember who was working on them.
 
I seriously doubt we'll see any effort in this area. Think about it . . . after the R&D, new parts, (supplier headaches), how many do you think they would actually sell? With the correct setup you should be able to achieve near what you get on the HVX from this camera without an adapter.

Even with a 1.6 Cineprime wide open, the DOF is about the same as F8 on 35mm, so a DOF adapter will still be needed.

The Brevis will work now on this camera, and I know Dennis has said that a relay lens for 2/3" cameras is in the works.
 
I mean, we can use any 35mm adapter with the cam but we need a relay lens that can help with the 2/3" focusing. Dennis Wixom apparently promises a new relay lens ASAP. I hope we will see it soon !
 
I don´t want to hijack this thread but I think it would be interesting for the understanding of the issue to know why there should be any limitation of 1.6 for the aperture of a Cineprime. Is it too difficult to build a Cineprime with an aperture of 1.4 for example? Where are the limits? A prime without adapter that creates sufficient DOF would be the fastest and cleanest solution for 2/3" cameras.
 
In order to get the same depth of field as 35mm film from a 2/3" camera, you'd have to open up by four stops. According to the Panavision calculator, you can get the equivalent field of view from a 35mm camera with a 50mm lens, as you would from a 2/3" camera with a 23mm lens. But to get the same depth of field as the 35mm camera at f/5.6, you'd have to open the 2/3" camera up to f/1.4.

I guess that means that if you wanted to match the performance of a 35mm camera shooting at f/2.8, you'd need to use a lens on your 2/3" camera that could open up to f/0.7!
 
I have gotten the m2 to work with the HPX500 using the fuji lens as a relay but I havent had a chance to test the resolution yet - I plan on checking this soon and I will post the results here.
 
Uh, that's great... But the thread is about 2/3" DOF adapters for those who own such cameras...

Back on the subject, does anyone know how Dennis (or anyone else) is doing on a relay lens?

But I'm betting that the CAC needed for that kind of aperture is either nearly impossible to design, or prohibitively expensive. Not much point if a 1.4 2/3" Cineprime is going to cost $60K.

Single CMOS will save the world.
 
And what´s about the Angenieux/Zeiss 35mm adapter? (Not based on a proyection plate but on a system of optical lenses) Should be prohibitively expensive but JVC presented something similar for their 1/3" HD cams for about 4000$. It looked really clean on a demo clip and is said to consume only 1/2 stop of light. (In the case of JVC the adapter is designed for 16mm lenses but the DOF was clearly shallower than with a 1/3 sensor). Maybe there are still a lot of things to come in the future...
 
The Angenieux/Zeiss 35mm adapter is beautiful, but costs about the same as a PRO35. Once REDs are readily available, neither of these solutions will make any sense.

The JVC HZ-CA13U would have been great if it was 35mm rather than 16mm. Super16 is just the teensiest bit bigger than 2/3", so unless you're going to run superspeeds or master primes, there's hardly any difference between the PL adapter and just using a 2/3" Cineprime. The adapter gets you 1.3 over 1.6, but then the adapter is adding a whole lot of glass into the optical path. It doesn't seem worth it.
 
I have the HPX500 and Brevis35 working together. The Fujinon lens works as a relay lens - that's the good news. The bad is that the camera looks like a bazooka since to attach the Brevis to Fujinon, you need to add extender tubes.

The resulting image, btw, looks great.

Once there is a well working adapter for 2/3 cameras for under 10k$ there would be hundreds or thousands of existing cameras ready to compete with the RED.
