Can you imagine the lens for a 4 gig sensor?

The lens would have a 24 inch aperture!

However, the article does not describe a digital camera; it is a digital imaging system. If you read carefully, you will find that the camera uses film to capture the data and the film is then scanned. The remarkable thing is that the whole system is working to the maximum spatial resolution limits afforded by the characteristics of the film, since the lens is perfect and the scanning process has been matched to capture just the maximum from the developed film. A truly remarkable achievement.

The sensor is chemical, but there is a great deal of digital about it. As an example:

Quote:
To focus the lens accurately, Flint measures the distance to every major object in the field of view with a laser range finder. He then plugs the distances into a set of algorithms that tell him how to adjust the screws.
I think it is safe to say that he is not using a slide rule to work the numbers through the algorithms.

I'm not sure about the 'capture every blade of grass' bit. I thought that if objects are really far away, then you need a telescope to see distant objects very clearly. Like....a sensor with heaps of pixels won't necessarily let you see every detail of very distant objects, right? I mean...a big sensor doesn't necessarily have the same function as a telescope right?

Greetings - What you say is true, however, "telephoto" is a relative term; depending on the relationship between the actual optical image size and the size of the film/imager. The digital imaging system described is essentially a perfect large-format film camera with a perfectly matched scanning system. Since the camera is large-format it normally uses lenses of longer focal length, which would be experienced as "telephoto" if you were to tape a frame of 35mm film into the camera's large film holder or if you were able to mount the lens on a 35mm camera. So, the final large film image can be thought of as a collage of telephoto images on a single piece of film.

Hope this helps.
