Canon has published a patent showing a series of fast prime lenses for camera bodies equipped with a curved sensor. The only way to get the advantages of a curved sensor is to have lenses dedicated to it.
Curved sensors would reduce the complexity and likely size and weight of high-performance lenses. The caveat is that supporting a curved sensor will require each lens to have its own radius to be compatible with the curved image sensor.
The following optical designs appear in patent: 2019-166711
- 35mm f/1.0
- 35mm f/1.2
- 35mm f/1.4
- 50mm f/1.0
- 50mm f/1.2
- 65mm f/1.2
- 85mm f/1.0
- 85mm f/1.2
- 100mm f/1.2
Can we expect a curved sensor system from Canon? Who knows at this point, but both Sony and Canon are working on it. Are there enough camera buyers to support another mount?
For Rolls Royce drivers...
Or could movable elements within the lens focus the light according to the body attached.
Or would curved sensors be used on APS-c bodies and in that way be a whole new smaller mount system.
the secret of film lenses is that they (at least, almost all of them) weren’t designed quite with a flat field in mind. Pretty close, not not completely. The problem is that film is never truly flat. The corners and edges are curled a tiny bit towards the front of the film plane. Unless you have a vacuum holder, of course. Not everyone did, did they? Mostly just specialized work, and then, usually specialized lenses. I had a copy machine in my lab for reproduction work, you know, halftone dots. Pretty critical everything matches up. So vacuum holders for the original and the four big film halftone repro. True apo flatfield f9 lenses. But otherwise, nah.
use most of those lenses on digital, and often the corners, and possibly the edges, are out. Maybe not by much, but you’ll see it.
lens design is easier if flat fields aren’t required. Hence all of those f1.0 and f1.2 lenses there.
You've got no idea how much mine costs me !
It's possible you misunderstood his joke...I can't be sure whether you did or not. He's assuming the driver is a chauffeur (who probably can't afford an R5 unless he eats Ramen and has no family) and the owner of the car (not the Rolls Royce company) is in the back seat.
However, I am sure a lot of Rolls Royce owners do drive their own vehicles.
