Yes, I like this design compared to the last version, looks more like a classic series in the making. Kinetta(??) should start being worried. I think this one looks more like a cinema camera, and the Kinetta like an odd camcorder.

I give it the Big Wink ;)

Viewfinder
 
@Ivan,
In general, viewfinder is no problem. Now, scince we solved the problem of displaying 720p full resolution on one viewing device and downscaled in a good quality on another viewing device both in realtime at the same time, there can be all sorts of combinations. It's just that we couldn't find a decent viewfinder >PAL resolution yet for a reasonable price.

@Wayne,
good to hear that you like the new design. All the questions and wishlists by the community were really helpful to improve the thing up to this point. The concept is still modular, the sensor head can still be detached (no more sweat, operating a steadycam) and we can now work with our experiences and the software on future sensors. So I guess, this is the first upgradable camera been build...

Cheers
Markus

Has it built in hard drive? How about 35 mm adapter? Will you build it with Altasens CMOS? How much will it cost?

Markus,
I have got a nice :) email from Rai. I replied but he is busy (like always). Contact me off list please since it will take forever for him to check his mailbox.

Yes, classic, it is good to have equipment you like keeping for life (like the old days).

Dan is that your 35mm adaptor on that system? could it be?

Gary McClurg April 1st, 2005 11:06 AM

Was wondering if you guys could make a mount to hold Arri 35 primes?

Dan Diaconu April 1st, 2005 03:17 PM

Obin,
Any 1 or 3 CCD/CMOS (of any size; 1/4", 1/3", 1/2" or 2/3" ) can record images of a GG (with the appropriate hi rez lens for the given CCD/CMOS size) thus enabling the prime's DOF be captured electronically. As long as chips will be smaller than 18/24 mm, what I have done has an application (for the purpose of shallow DOF) Whenever they will be fully "grown up" and mass produced, the GG and all this work will not be needed anymore. Is going to be a while though ...(I hope)


Gary,
Pl mounts are sold by many:
http://www.visualproducts.com
http://www.cinematechnic.com/products/PL_Mount_Adapt_ARRIBay.html
To many to list, just goggle for PL.

Now,... some are even matching my sense of humor:

I'll get two (for breakfast)

I hope that price is in Italian Lira ;)

Obin Olson April 2nd, 2005 02:28 AM

so dan is that your system on the camera or not?

Markus Rupprecht April 5th, 2005 07:57 AM

The camera currently doesn't utilize a GG unit. We find our collection of 2/3" lenses (really fast, most are f <1.0) very good. They are part of the system and define the "look" of the camera. The front part you see is the camera head, containing the sensor. It is detachable if you need it.

That looks great, guys. It is so nice to see a modular design
with upgrade path for bigger better cmos chips.
The first clip made with the drake showed a shallow depth of field. I think you are right in not giving up resolution for a marginal increase in depth of field your 2/3 chip with ultra fast lens seems more than enough in creating this look. I would much rather save my money for the 1080p chip, solving the problem once and for all. These cameras also have some very green sensibilities. We won't have to landfill perfectly good cameras just to get the newest technology in chips, and we will be able to cut back on the manufacturing of tapes as storage gets smaller.

thank,s again your camera looks realy cool

Once the magazine hits in April will you be able to post a copy or link to it.

Rai Orz April 5th, 2005 04:59 PM

... 3 days till the story come out (magazin CUT), yes, link will come...

Time for more details?

As Markus say, Drake need no 35mm adapter, because with those extreme fast lenses (f stop under 1) our 2/3" CMOS produced near 35mm DOF. This work, because our sensor have NO build in microlenses. Why dont use other camera manufactors those lenses? Why cant you find HDTV primes with those wide open iris? Why say people, those lenses are not sharp? Its because ALL other sensors, CCD´s or CMOS have build in microlenses (from Canon over Altasens to Varicam). But with microlenses and f stops under 1:1.4 the pictures washed out. Drake have no microlenses (also DALSA and ARRI), thats why it work. See also this DALSA PDF (Page 7):

http://www.dalsa.com/dc/documents/Im...8-00_03-70.pdf

Another point about Drake´s sensor: Fillfactory produced also the IBIS4 14000. It work in KODAKs DCS Pro 14n digital still reflex camera (its a full negative-size 35mm color imager with 14 megapixel resolution) This is one of the worlds top high end cameras. Internal IBIS4 and IBIS5 based on the same technologie.

Mono VIEWFINDER: Times are changed. Now, Drake got also(optional ?) a mono viewfinder.

BTW: I found a cheap way to build full resolution HDTV viewfinders. (full 720 and also full 1080, mono or color). Its crazy, but it work...

Obin Olson April 5th, 2005 06:43 PM

Rai PLEASE tell me how your building HDTV viewfinders!! I want to know! GREAT WORK!
