Flip out/rotatable lcd screens are nice but they don’t add much value for me since I need to use a LCD “loupe” to see the screen when filming outdoors and, of course, the extra magnification provided by the loupe is nice too.

oh speaking of a rig for this camera, here’s the first one I’ve seen:

Yeah the spec list is going to put real pressure on the major manufacturers, or at least in a sane world it should but who really knows, maybe they just ignore it and hope it eventually goes away. There are still lots of questions I have about the camera, for instance
* clip length
* ISO range
* full control over audio? (no AGC is what I mean)
* They said something about auto-iris – hopefully the camera has a full manual mode tooBut what about the shape? it looks like a wedge shaped toaster, hard and uncomfortable to hold I would think. The “handles” look like a joke and won’t help with stability much at all – for handheld work this is going to need some kind of rig.

Here’s a link to the specs page…
https://blackmagic-design.com/products/blackmagiccinemacamera/techspecs/
Disappointing at this point is the sensor size….wikipedia says that APS-C sensors: “…APS-C variants are considerably smaller than 35 mm standard film which measures 36×24 mm. Sensor sizes range from 20.7×13.8 mm to 28.7×19.1 mm”
The specs for the BlackMagic camera say:
Sensor Size 16.64 mm x 14.04 mm
Active Sensor Size 15.6 mm x 8.8 mmSo let’s see how this impacts low light performance

Today’s announcement by BlackMagic on their new cinema cam shows the way forward…here are a few details of this $2,995 camera
Raw recording.
2.5k – I don’t know what size sensor this means…is this full frame or APS-C or…?
13 stops dynamic range
Integrated SSD to record Cinema DNG Raw, ProRes and DNxHD
EF and ZF mount lenses (ZF? I thought that was the Zeiss Nikons?)
SDI and Thunderbolt (!)
Integrated touch screen LCD
Free full copy of DaVinci Resolve
It doesn’t say the actual size of the sensor. I would guess Super 35mm
$2995! Shipping in July.

Yes that’s right, I just took a look at one of my 1080p 24fps H.264 cameras right out of the camera and that’s what it came to. I use class 6 or 7 cards and they work fine for H264 but not sure they can handle RAW, probably couldn’t.

Hmmm, my math came out much different, check me:
TIME 1080p RAW (24 fps)
per sec 5.25MB 480MB
per minute 315MB 28.8TB
one hour 18.90TB 1.73Pedabytes(sorry the forum software messed up the alignment, imagine 3 columns)

“..Why do only professional cam-corders and professional film cameras (i.e. Arri Alexa, Panavision, etc.) have an option to shoot totally, 100% raw videos …?”
Because that would be just too awesome!!I think storage does play a role, perhaps bit rate and card speeds too but most of all I think it is seen as a premium feature that they want to reserve for their most expensive cameras as a purchasing incentive. It’s a bit cynical of me but I think it’s just a fact that manufacturers often “hold back” certain features so that they can construct an entire line of products and to give the buyer an incentive to spend a little more money on the next model up (or sometimes a LOT of money)…and some of the decisions as to what feature goes into what model seems pretty arbitrary, in other words not related to a technical or cost consideration but to a business/marketing decision.
For instance, the entry level Canon T2i COULD from an engineering point of view could have more of the features of the 5D MII and MIII but instead they have the 7D which gives you a taste, a little bit more but if you want, say full frame, hey that’s going to take you up to at least the 5D level or now the C300 or their newly announced cameras.

First of all things like sensor size and megapixels do not automatically create better images – a lot has to do with the quality of the engineering.
The issue you are having is with the lens…it is not fixed aperture which means it is going to get darker as you zoom in. Sony does sell a fixed aperture wide angle lens:
It’s 16mm and 2.8 which is fairly fast – helpful for those narrow depth of field shots. That’s about $250 and would be a much cheaper solution than buying the T2i – now I’m a big fan of the T2i, that’s the only camera I use right now, but still it might be worth trying this cheaper alternative out first – if later you get the T2i you can keep the Sony as your “B” camera for either multicam shoots or as a backup unit.
