scarlet 2/3 vs s35 depth of field

I am sure I will eventually figure this out on my own by actually doing it... I just need a simple yes or no answer on this one. Can you get the 35mm look from a 2/3 inch sensor? That is without an adapter. By this, I mean that I want my subject in focus (fore ground or middle ground), be relatively close to it, and have a nice blurry bokeh in the background. I realize that this aesthetic is only one of a cinematographers tools, but I want to know if it is possible to achieve on the 2/3 scarlet?

P.S. You guys are awesome! I am poor. I want to get the most economical solution so I can purchase lighting gear. I feel like if Red made something like the D5 Mark II only had it record raw I would be in action. Maybe Jim will hear this and drop in his 2 cents...

God bless Red,

The short answer is yes. 2/3" properly handled can produce shallow DOF for the type of shot you describe. Red will make both S35 and FF35 Scarlets that are a bargain at their announced prices. Raw motion data rates require much higher processing power than is built into a 5D. Even for highly compressed AVCHD, Canon doesn't have the processing power to sample more than 1/3rd of the pixels on its sensor for motion. You get what you pay for.

Have you seen the sample shots taken with the 2/3" sensor?

This is basic photography. The 2/3" sensor gives you an effective increase in depth of field as if you stopped down a 35mm cine lens by 2.5-stops once you match field of view by using a shorter focal length compared to 35mm cine (divide the focal length you would use on a 35mm movie camera by 2.5 to get the equivalent focal length in 2/3" -- so instead of a 50mm lens, you'd use a 20mm lens, for example.)

So if you shot at f/2.0 on your 2/3" camera, it would look like you were shooting 35mm at a f/4.0-5.6 split. Whether or not that is acceptably shallow-focus is up to you, but in your typical close-up, the background would be soft at that stop.

Rent "The Curious Case of Benjamin Button" or "Zodiak", both shot on 2/3" cameras and decide whether the backgrounds are soft enough in focus.

we weren't pushing in tighter either to make the focus drop off faster.

This is such a key point. Yes, sensor size, lens aperture and focal length affect your DoF, but the distance from your subject is a huge factor, possibly even the largest. If you want shallow DoF, move closer.

A great article about it:

Sorry to interrupt but this is beginning to irritate me, it's ZODIAC, not ZODIAK...
