Holy crap I am eating my words

2/3rds will be at 2/3rd according to what I read from the Red team. Slumdog, Revenge of the Sith were shot on 2/3rd. It can be done. I'd hate to see beginner filmmakers pass up the opportunity because they wont get anything below S35

Agreed. There's nothing wrong with 2/3" Sensors. Ty for compliments as well, Nox.

I am now interested in the Fixed I just hope I wont miss out on too much DOF switch from APS-C to 2/3... what do you think

2/3" DOF is nothing like APS-C DOF. There's a very good reason companies like P&S Technik make the Pro35 adapter for 2/3" cameras.

also do you think the DOF is going to look closer to the 7D in the interchangeable 2/3 compared to the fixed 2/3

It will make no difference. 2/3" is 2/3", regardless of what lens you put on it; at equivalent focal length they'll have the same DOF, and neither will be anywhere near the level of shallow DOF you can get from a cinema-sized sensor.

The 7D's sensor is about 6x as big as the 2/3" sensor.

To get comparable DOF, you'd have to open up the lens 2.75 stops (or, let's just round it off and call it three stops). So if you have a 7D, you can actually find out exactly how much DOF you'd get with a 2/3" fixed Scarlet. The Scarlet has a maximum iris of f/2.8, so set your 7D on f/8 and that's the shallowest you'll get out of a 2/3" fixed scarlet.

If you went with the interchangeable-lens version you could get faster lenses which would help close the gap, but even with the very fastest lens they offer, the T1.5, you'd still have equivalent DOF on a 7D if you set the 7D all the way down at f/4.

There are many reasons to consider a Scarlet 2/3", but the super-shallow DOF look is not one of them.

Good Gravy. I knew it was small but didn't know it was THAT small. If I end up getting a 2/3rds I'll most likely get the fixed kit version, with a fast lens designed for 2/3rds. For under $5k you've got everything you need to shoot, with a slew of amazing fantastic features.

My 7D will still have a use. Crash cams, extremely shallow DOF (comparatively), B cam. No one should just have one tool to work with
 
That's what was announced long ago; I don't know if that stat is still current. I thought I'd heard something about 2.6, but even so, that's only 1/3 stop different.
 
Hey barry, Kholi mentioned the FOV will be different with the 2/3 I understand that, but it that onlt If I was using FF lenses? Say for instance I nut the Fixed Scarlet... The widest is (i dont actually know) say 8mm is that the same as 8mm with a FF cam since the lens on the cam is made for that sensor? also say I but the interchangeable... I buy the 8mm lens, since that lenses is made for that sensor would it be the same if I had an 8mm on my 5D or is it still a crop sensor i.e.(8mm interchangeable on the scarlet will be ??mm)

Crop factor is a product of sensor size, not lens image circle.

2/3" chip has a crop factor of 3.93.

8 * 3.93 = 31.44mm

So any non-fisheye 8mm lens (2/3", 16mm, 4/3", APS-C, FF, 65mm) will have approximately the field of view of a 32mm lens on a full frame camera when mounted on a 2/3" chip**. However, if you used a lens for a 1/3" chip, it would vignette. The image circle of that lens would be too small to adequately cover the surface of the 2/3" chip.

**Due to the nature of optics, its difficult if not impossible to find commercially available 8mm lenses that are not fisheyes or show severe distortion for FF and especially for Medium Format.

Thank you for the great information. This post answered a lot of questions for me.
 
Scarlet Fixed is f2.4 T2.6, focal length range is not yet announced other than it is x8 zoom

On the nov30 thread a question was asked if it will be 7.5-60mm, Jarred responds "Close.. "

7.5-60mm is the equivalent of 18 or 19mm to 147mm if it were a 35mm zoom

will I be ditching DSLR's for a 2/3 fixed? hell yeh, 2/3 dof will be really good for narrative work because
actors will be less likely to drift in and out of focus
 
have you seen Curious Case of Benjamin Button? or Slumdog Millionaire

Both are great examples of dof on a 2/3 sensor because they were shot on SI-2K which has a 2/3 sensor

the only thing that is keeping me on the yes/no line is the cost of post... I have a 27in iMac with 3.06GHz dual core and 4GB 1067 DDR3, also a 2.93 dual core with 4GB DDR2 and I know neither of these will be able to handle RED footage in real time, that is not without the redrocket card and MaxxDigital deck there is $6000
