RedRock M2 versus Cinevate Brevis : A Review...

Len, that's right. All units will have the new Nikon mount as well as the new drive system .... in-progress units too :)

DC, as with most things photographic, fast lenses are usually more versatile. If you read up a bit on f stops, and aperture, you'll find that each f stop increase halves the light available to the camera/adapter. You want as much light as possible usable, so 1.2 to 2.8 represent fairly fast lenses. It's good basic knowledge to have, and applies to the video camera too :)

Dennis,
Here's another question for you.
I assume you can use Nikon "D " lenses which have a smaller target area just by zooming in on the HVX lens. What if any are the downsides of doing this?
Do you lose resolution or exposure?

Similarely, if you use PL mt lenses like Zeiss or even Oct 19th lenses, the target area is smaller thus requiring you zoom in more. Is there a trade off on resolution by using lenses that have a smaller imaging area (analagous to blowing up from a smaller negative say)?
 
Thanks. It was the term "slower" that threw me off. I realize f1.4 is a wider aperture and allowing more light in than f2.8.
 
Dennis,

Some questions, sorry if you posted this elsewhere. I have the M2, but really need something for lack of power lighting indoor and night scenes.

I'm on your website ready to order the HD bundle. Is there a more filmic
Cinefuse 3 about to be ready to ship? And when?


Also, how far out is the fulfillment of the HD bundle from time of order?

Most folks these days (me included) are looking for primes. A nice set would be 28mm, 50mm, 85mm and perhaps a 135. Optimally, nothing slower than f2.8 . There's some stunning HVX footage from Ken Willinger using a fast Nikor 16mm on the Brevis. This is not the hot tip for shallow DOF, but a great lens to have in the collection.

These would combine to give both the best image quality and range.

I understand that. But is it possible with the Nikon 18-200, is there a great quality loss? I do a lot documentaries and sometimes my style is zooming, focussing and mostly I use the zooms and focus corrections while editing as a 'style'.

Another question. What does this set of primes costs

thanks very much
 
I'll try and get all those questions answered :)

I have tested academy format lenses and yes you do need more zoom in room. The footage using LOMO cinema lenses and CINEFUSE 2 was very good, and this was using the GS400...not the A1. I'll be doing some testing with the A1 and the LOMO lenses and based on what I've seen so far, expect good things. That being said, the Brevis is designed to use an image size potentially larger than 36mm wide for 16:9 cams, and the vast majority of shooters are using 35mm format lenses. So you can likely use the smaller format digital lenses, but they would certainly have to be very fast, and there would be some tweaking to do.

Dolph, a set of reasonably fast primes from ebay..like a 28mm, 50mm and 85mm set of Canon FDs would likely run about 200 to 400 dollars depending on condition etc. I do have a 28 to 70 f 2.8 zoom which works perfectly. When you zoom to 200, effective aperture drops a great deal, so you either need a huge amount of light, or a very, very fast zoom to use the full range. I always suggest testing each lens and your camera carefully for sharpness at various f stops, edge fall off, and chromatic issues first before heading out to an important shoot.

Scotti, CINEFUSE 3 should be in the pipe by month's end. The first part of this clip from the A1, using C3 was shot using the light from a 2x4 window, (there's another 10 feet to the left) and no addtional light inside at all. The A1 was at f 2.4 and the 50mm FD at f 2.8, with camera gain at -3db. I hate noise, so I try to stay away from gain...in this case negative gain.
 
I met up with Phil Bloom today in London, very nice guy indeed. We did a little testing with the Redrock M2, the Brevis35 and the SGpro R2. Phil will be doing a write up on that over the next week, with footage and res charts.

1 thing that I learnt today was how easy the Brevis is to setup and use, since you dont need to adjust any rods support! Nice work Dennis
 
Thanks Wayne. It's just too bad I couldn't have been there for a some shooting and a brew or three :) My goal with the adapter has always been to make it as user friendly as possible. With the new drive system, Nikon mounts, and particularly the latest diffuser, it's slowly maturing into a product that I'm almost 100% happy with.

Phil is doing some really great work there.

What do you think about a Nikkor-P (Nikon) 1:2.5 105mm?


 
Yes it is rotated 180, although our flip module for the unit is in the prototype stage. It is a discrete, removable module designed to work with existing units, as well as any other adapter :)

Got a rough release date on that piece yet?

When can we see that full testing, sound very interesting before digging into a choice for adapters.

What is the approx light loss?
 
Just a note to M2 users... When you get your first lens, get a f2.0 or lower. I have a 28mm f2.8 and just picked up a 50mm f1.4, WOW! what a difference. The 28mm is outta here! It does pay off to get a faster lens.
