I don't really know what to think of it really, except that it's a great feature. I'm just so blown away really. I'd even go and say if it's not in a Pentax DSLR, I'd maybe in fact jump ship to where ever it's going to be at.
On the technology page, it get's more interesting:
Refocus Imaging
"
The Digital Lens platform provides the following new capabilities:
- Focus photographs in software after the shot
- Choose the depth of field after the shot
- Dramatically increased sensitivity for low-light shots
- Revolutionary correction of lens aberrations in software
The Digital Lens platform enables the following advantages:
- A greater yield of good pictures by focusing after the shot
- A more responsive camera by reducing shutter lag
- Pictures with better lighting by reducing the need for flash
- New lenses with unmatched performance and low cost
The beauty of the Digital Lens platform is that it requires only two changes to a conventional camera:
- An incremental change in hardware: a new microlens array in front of the sensor
Refocus' proprietary software
- The incremental change in hardware creates an enormous increase in the power of the recorded light.
A conventional camera records only the average value of the many light rays striking each pixel. A Digital Lens camera records each of the individual light rays, providing much more information to compute better pictures."
Pretty interesting stuff.
