35 mm lenses on hpx500

i worked as an AC the other week on a doc shoot that was using the PRO35. Even know it was a doc shoot and we were running around a good bit, the adaptor worked really well and was pretty straight forward. Unlike adaptors on the smaller camera, if you put on the PRO35 and a prime lenses, its actually smaller(or at least about the same size) then if you had a regular lens on the camera. The downside is that the PRO35 is something like $10,000 (dont quote me on that one thought).
Letus is coming out with a b4 relay lens that you might wanna look into. There has been a bunch of post about it.

You need both the B4 adapter and the 35mm dof adapter in order to use still lenses on the hpx 500.
Letus b4 is $4500 and the Letus ultimate is $4500. Cinevate promised a below $2500 B4 adapter but there is no clue of its existence yet.

IMO and please just remember its my opinion, I find set up times for the adapters time consuming, you must follow a checklist to the letter (which I realise you need to with any lens change - but its much simpler). And, one inadvertent knock etc can mean you must go through it again. I have heard this isnt the case with the pro 35 but havent used it myself.
And then - a 2/3" camera isnt a 35mm camera, so why would I go to so much trouble to ensure I get a 35mm equivalent image? THis is a 2/3" camera and there are primes made to use and ready to go with a 2/3" camera. I can understand it on a small format cam such as HVX etc. when there simply isnt the interchangeable lens options. But if you use the right 2/3" primes based on conversion, theres little difference. Is it just me? I rent.

Digiprimes give you a great look. I have a list lying around somewhere I got from my sales guy in New York. I haven't gone to any of the camera demo's yet, but digiprimes especially will give you a very nice look with a 2/3 camera. Granted this is with an F23. But the same concept should apply.
I would personally rent nice glass. Look at Mark's entry RDPM. That was shot with a fujinon HD glass with the HPX500 and it looked great.

I have recently got a set of canon EJ series primes and an hpx500, I am currently testing the setup, but I would never look back at the boredom of having a 35mm adapter in the loop! Digiprimes slot straiht on,no beeping ground glass etc!!!!! no poor construction issues, no grain appearing randomly... its all good.

Yes, and the very expensive 2/3" Cine lenses will give you the exact same DOF as any 2/3" ENG lens.

Sorry guys, but this is a myth...
Recently we shot with my Varicam a TVC with a set of Leica R lenses, Brevis35 and my GG.relay B4 adapter for brevis...
We had on front lens F4 aperture, so we ware focused for a 40cm area, the Lens was 35mm F2 Summicron, camera to subject distance was 1,8m. I was having beautifully defocus background/foreground, slightly wide FOV and the subjects were focused sharp.
That's Impossible with Ej's and Cinestyle Zoom's, and I can tell because I own both...
To get similar results you need to have the 12mm lens in F1.8 and get DoF of 12cm, that is not enough to have the subjects sharp... and the background would not be as defocus as it is with the Leica lens with S35 DoF...

Oh, please.....
This is one tired conversation.
It's not unlike the G35 thread on here...
Years and years and years of fact-free nonsense, and once it comes out..we've moved so far from the ancient test footage from the DVX100 that G35 STILL has on their site as the best they can offer.....and,who really cares?
Letus and Cinevate are being SO silent about relay lenses.......
This new thread of rumors with no facts to back them up just may be the "G35" of 2/3" adapters.
YAWN, Y'all!!!!!

Might be a silly question but I genuinely don't know... when you film with the Letus 35mm adapter does the footage come out as 16:9 or the film size (I think it's about 2:1 or something)?
Dino

If the camera is 16:9, you will get 16:9 frame size from the Letus or any other 35mm DOF adapter.

Just to add to this point, as avengelos added the information is not correct.
The Canon FJ lenses are a very good example of Cinema style 2/3 lenses, they are superior to standard lenses and offer better DOF because they are faster. But there is no free lunch, the imager is 2/3 and physics are still the same.
I like using this set because, they are identical in size and weight so when running a steadicam changing lenses does not mean re-balancing the entire rig. Same for on sticks, motor placement...etc
For film DOF you still need 35mm imager.
You can find a link to the canon line of prime lenses here:

You are right. An extra stop will offer a shallower depth of field, but if comparing one 2/3" lens vs. another, be they ENG or Cine, and shooting with the same stop, the DOF is the SAME, no cheating physics. Neither will give you
35mm FOV or DOF.
A 2/3" cine prime is not a substitute for a 35mm DOF adapter--sure shooting at
a 4.0 on a 35mm lens and 1.4 on a 2/3" lens will come closer to a similar DOF,
but a Zeiss Super Speed T1.3 vs. a 2/3" at 1.4 is no contest. Ditto field of view.

I guess they grew tired of giving unrealized delivery dates. "We'll have it next quarter.." was claimed one too many times.
Like you, I just yawn when I hear about these mythical relay lens. My suspicion is that they gave up on them. The new RED gear, and especially the next rev of HD enabled Canon and Nikon 35mm cameras, will make the whole adapter business obsolete.
