Aaton Digital Camera

Just looked at the latest Aston sheet for the digital Penelope, no doubt just out for NAB.

The interesting bit is how they're achieving the camera's lower ISO rating by using a multi slot shutter with a 100 ISO setting, so avoiding the use of ND filters. I was wondering how they were managing it. I expect there'll be a lot of testing for artifacts from this new arrangement.

The 100 ISO shutter looks like a very clever soloution.

Looks like an amazing camera. delta_profile1_531_2.jpg

 

CCD eliminates rolling shutter issues.

 

http://www.aaton.com/products/film/delta/

 

The first optical viewfinder digital camera with an internal SSD recorder (DeltaPack*) for full rez CineDNG ucompressed RAW (the Adobe archival format based on open standards), and editorial-ready proxies.

* DeltaPack is compatible with the codex® backstage and post station workflow.

 

Lightweight: 7.5 kilos with internal recorder and two onboard 14V Li-Ion batteries. Two to five hours‘ autonomy; power dovetailing during changes.

 

Designed for earthlings, Delta respects Aaton‘s first commandment : Cat on the Shoulder profile, plus wide flat base for tripod. No eye-strain bright viewfinder with large peripheral coverage. . Rotating mirror shutter; no rolling shutter artifacts.

 

Main selector eliminates complex menu navigation and gives direct access to operating functions from both the operator and assistant sides.

 

Location sound-mixer friendly, Delta is noiseless in both record and pause ( 

 

Unlimited number of cascadable preset 3D LUTs for RAW metadata on one hand, and for on-set control screens on the other.

 

14 stop dynamic range Super35 Dalsa® CCD sensor, 800 and 100 ISO sensitivities (patent pending) eliminate the need for special anti-IR neutral density filters. 90% pixel-fill allows for wide angle lenses with short exit-pupil distance.

Do they state the sensor's native resolution anywhere? All I can find is:

"Dalsa® sensor’s 90% pixel-fill allows for 7K pixel sampling"

 

If you can afford the mirror shutter, Dalsa's simple 40-year-old CCD design still gives the best results, since almost the entire silicon area is used for photon capture, without the complication of microlenses.

Whats going on with those slits ?

 

I assume it's a means of reducing the amount of light passing through, without reducing the effective shutter angle. I guess it acts as a series of travelling slit shutters, which combine to provide the complete exposure.

Does this mean that non-film movie cameras will finally be able to record red lights without them turning white and/or pink? Current digital nighttime street shots are already looking dated.

 

Any word on shipping dates or price?

Ah, ok - I (mis)read 'multi-shot' in your first post which got me thinking too much... Yup, I get it, and you've already touched on temporal aliasing issues which was my next thought.

We also now need a new folder; clearly this doesn't fit in "Aaton Film".

Why not just "Aaton" since there aren't that many Aaton-related posts?

Or is that about to change...? :rolleyes:

Interesting to find out theory behind that, it could be a perceived "dynamic" resolution over a number of frames as against a stand alone single frame resolution. The Camera records RAW, so there could be a bit of post processing going on.

 

Here are some test images:
