Brevis 35 vs. m2 redrock adaptor

I'm looking to get a lense adaptor for the HVX...I'm curious if anyone knows the differences between Brevis 35 and the m2 redrock adaptor
 
Both produce fantastic images when setup and used properly. I've seen images from both that rival one another. Do some research and get the one you feel is right for you.

I have one of these two on order right now.
 
a friend and I are doing a side by side comparison of the M2 and the brevis as soon as the brevis comes in... results coming as soon as possible
 
Very interested in comparison AT, one of my favorite lenses is an aspherical 28mm -300mm Tamron zoom lens, will that be able to be used with the M2 or brevis?
thanks
 
What speed is your 28-300? Best results are generally with primes, particularly fast ones. The effective max f/stop for some zoom lenses at 300mm may be something like f6 or so, meaning you'd need a ton of light to make this work!

I've just got an 80mm OCT19 Lomo (cinema lens) which at f2 is almost making me cry. I will literally be breathing over the shoulder of our CNC folks to get this thing mounted.
 
Thanks Dennis, range is 3.5 to 6.3 , sounds like it should be OK around 5 to 6 is fine anything else, and I have to move closer to the Sun. Thanks. I will be making a decision this month and depending on Cinepoter expenditures I will get some 35MM adapter soon.
 
Like Abstract Theory just said, he and I will be doing a shootout between these two adapters with a little write-up review to go along with - I currently own the M2 and I love it, except for a few issues - The Brevis caught my eye due to its easy setup time and run and gun abilities - We will know soon enough!

The test will consist of Nikkor lenses and a 3-5 locations and lighting setups..

28mm 2.8
35mm 2.0
50mm 1.8 (my favorite)
85mm 2.0

Expect this around the third week of October..

I heard that the makers of the Brevis actually claim that you gain a half-stop of light when you use it. That cannot be true, but it's interesting thing to look into nonetheless

Dude the Brevis is almost too bright. The original GG has very little diffusion while still producing a pleasing Bokeh. While I don't run around measuring stops, I know i'm not losing any with the Brevis. Stopping down your lens is a must when using the Brevis with a fast lens.
 
It is very bright...and we recommend ND filters on the 35mm lens in bright conditions. The GG is like film, overexpose it and your image suffers. I responded to the light questions here...

Basically if you are using a 50mm f1.4 lens, expect the total loss from the adapter and lens to be .5 to .7 stops. Add another .3 to .5 using the diffuser option.
 
That pretty much sounds like optional screen element that comes with Redrock M2. It has less diffusion than CineScreen which is built in M2 by default. If you want to shoot in low light with M2, you can change the screen element, but CineScreen is the best in most situations.
 
Does the Redrock M2 invert the image so its not upside on the camera's viewfinder? If not, are there any other adapters that do?...

the Brevis and the M2 both invert the image.
 
rdq,
That sounds like a great test but a little overkill for most of us on the forum.
the simple questions could be answered in a few minutes with one lens in one set-up.
1.Does it lose less light?
2. Is it as sharp?
3. It might take more time to answer whethr the alternate screens on the Brevis alter the equation on the above 2 issues.

The Movietube does not invert the image, however it costs upwards of 13,000 US, at that point it seems a little silly. I'd rather use the M2 as a work around and save $11,500.

I'm interested to see how the Brevis and the M2 stack up.

Too late for me though as I have the M2

Nathan thanks for the info. I am assuming, aside from using the movietube, with the other adapters get you get setup with a rig with an external LCD monitor that flips the image around... something like that, right?

... I took a close look at the movietube's website and... yes... 13,000 US is surely a lot (!) of cash, but, I have to say the system looks absolutely killer!
 
Indeed,

I didn't feel like using any of the work arounds to flip the image on the LCD ( Magnet, paper clip, etc..) so I'm buying this..

I know it's not HD but it's also much much cheaper. For now it will do the trick until I can get something better. I also religiously believe in using a field monitor for the director and DP, so the onboard is just so the OP can frame and do their job.

Oh and it's really easy to just turn the monitor up side down.

For sure the Movietube looks AMAZING. In a perfect world I'd have one on my HVX right now, but really, by the time you buy the HVX and 2 P2 cards, either a P2 store or a lap top, and the movietube your looking at well over 20k. At that price It becomes much harder to validate still shooting on a 1/3" chip.
 
I know you can mount any PL mount lense to the Red rock if you buy the PL mount version. Not sure on the Brevis35

Just noticed that 2400 x 480 thing,

The monitor was recommend by gear dear (geardear.com) so I trust them. I'll look into it though.
