Brevis 35 vs. m2 redrock adaptor

Hey Dennis, im going to do a side by side with the Brevis, the New SGpro, the Go35 and the M2.

Aram Bauman has the Brevis, Deedive has teh M2, i have the Sgpro and The Go35. This should be interesting.
 
NY most likely. next time yous guys is up in NY, drop me a line. i am flexible. the real ***** is getting everyone using the same lens.

i'll write up a whole article and everything...
 
I'm hoping Aram will have the rev2 Brevis for that test? I know he's sending the beta in for an upgrade sometime soon...
 
Brevis lens question

Brevis lens question

This lens has manual controls but says auto…is it a workable lens for the brevis? I went through your forum and could not find anything about these particular lens’


Nikon Nikkor-H Auto 1:2 f=50mm Nippon Kogaku Japan Lens


anyone know the answer? thanks!

That lens will work great on all adapters. I think the "auto" refers to the AIS functions introduced way back when - the idea that the camera could communicate with the lens to know it's f-stop, etc.

"Auto" nowadays of course means much different things :)

Yeah...basically it just screws on. - - The Brevis is like the Mac of the computer world.

Well that did it for us - - since mac computers nearly shut our operation down before we got smart and switched to PC's and Avid we certainly don't want to move back a step . . so, we'll go Letus or Red Rock. Thanks for that insight Jester!

Is it not true that the Brevis unit vibrates? I've heard that the vibration can affect some of the harmonics in picture. Comments?
 
The Brevis and the Letus both vibrate and I have never heard of nor seen any "harmonic problems" or any other artifacts from the vibration. Actually I'm not sure what that means. The spinning adapters also have motors so they vibrate as well. It's a new one for me - where did you hear that?

The Brevis imaging elements oscillate in a very, very tightly controlled motion. They are oriented to an accuracy of .001" in the Z axis and do not have any harmonic issues with cameras. If high shutter is used on an improperly tuned system, there can be issues...easily alleviated by adjusting oscillation, and/or using lower shutter. The system is well known for rapid setup, and ease of use.
 
I've never heard of harmonic issues with any adapter, but maybe it's different terminology :) . What you'll see with a rotating adapter is ability to shoot at higher shutter speeds, and to be able to stop down on your 35mm lens farther before you see any kind of screen artifacts.

Brian's right about the main design difference between spinning and oscillating or vibrating adapters. The spinners have the advantages he mentioned, but tend to be a bit larger and heavier so for example the non flip Brevis is easier hand held, that's the trade off.

Aside from those basic design issues, the differences come down to individual build & design issues and the nature of the diffusing screens in each. Have never heard of artifacting on any of them except for the static grain (& dirt or dust on the vibrators) you need to watch for. I think that's what Brian means by artifacting.

there won't be much weight difference when you mount the Brevis on rod too. Because in order to have good images, You need to use a mattebox with N.D filters, and also a follow focus unit , and an external monitor for framing and focusing because the small lcd on the camera is not going to give you critical focus especially on a HD camera. So that sums up that you also need rods when you gun and go with the Brevis.

A really interesting adapter combo is a flip unit from the Cinevate to fit in to one of these rotating adapters. That way, you get flipped image and a adapter that can handle high shutter speed with an afforable price. The other is the P+S that offers that , but you pay like so many times more.

David -- you assume someone is shooting HD with their Brevis and therefore needs the external LCD to focus properly. :) Some of us are still toting around a DVX. I find running-and-gunning with the Brevis a fairly easy thing. I just use the 72mm NDs I already had from my non-adapter days and stick it all on a DV MultiRig. And if I use my wide angle glass (which I tend to prefer), focusing is even easier. Granted, when I get that flip unit it'll be back to the rails and my regular matte box.
 
The Year Zero documentary was shot in Cambodia on an HVX using the Brevis. They shot the majority of the piece off rails, and found it most convenient to just screw it on and shoot. Patrick at stillmotion.ca uses several Brevis units on their XH-A1 collection for their wedding shoots. They find the same thing...screw it on, shoot, then remove for steadicam work. They do this in seconds. Everyone has their preferred style, and all we do is make sure there's a product option from Cinevate to take care of them. This philosophy extends to our CINEFUSE interchangeable imaging elements, rails systems, and the upcoming cinema tools.

With the Brevis and flip module, the system will be happiest on rails, but with small cams like the HV20, it will be quite possible to just leave the little cam hanging off our quick release at the back, and rails mount the Brevis rig!
 
the issues of light loss and the problems of getting the m2 set up properly, made my change to the letus extreme that much easier.I'm glad to see people like dennis and the letus company answer the cries of the poor indi filmakers at so an affordable price even though letus is still probably the cheapest of the adapters offering the flip capabilties at the moment.

...or the microX, which is the previously announced Redrock flip module.
