In line with a new report, Canon has patented 10 new fast prime lenses that run the gamut of focal lengths from 50mm by manner of 130mm and are significantly designed for cameras using a curved sensor. As such, some of the lenses well-known are terribly fast.
Canon’s new patents cowl a set of fast apertures: at least one choices an aperture that seems low-cost beneath current lens expectations and one choices an aperture that is attainable seemingly as a result of benefits of a curved sensor: 50mm f/1.2, 50mm f/1.0, 35mm f/1.4, 35mm f/1.0, 35mm f/1.2, 65mm f/1.2, 85mm f/1.2, 85mm f/1.0, 100mm f/1.2, and 130mm f/1.2
In line with the report, the patent goes into important factor, describing each f-number very significantly along with the precise focal dimension, angle of view, image high, and dimension of the lens barrel.
Canon is patenting these lenses from the angle of fixing the issue of needing a compact, high-performance lens however moreover providing a giant aperture. The current sensor and optical design cease this, nevertheless by integrating a curved sensor, Canon can meet every these targets.
As outlined in the patent, trendy imaging optical strategies use lenses with 13 or additional sheets of glass to attain an aperture price larger than f/2.0. The difficulty with that’s that whereas it technically works, the larger and heavier the lens turns into — significantly when dealing with telephoto lenses. Furthermore, Canon says that this sort of lens configuration tends to introduce sagittal coma flare.
Curving the sensor permits a producer to dramatically simplify the design of lenses in consequence of the rays of light that enter the lens after which hit the sensor journey the similar distance, regardless of the place on the sensor. The flipside of course is that, as Canon Info locations it, interchangeable lens design turns into far more troublesome as each lens would need a distinctive radius on the curved sensor. As such, it have to be anticipated that prime lenses could possibly be tackled first and rather more seemingly a fixed-lens design.
Nonetheless, the amount of lenses well-known and their description will likely be interpreted to level that they is likely to be interchangeable, which could not solely be stunning at this stage however moreover seemingly extraordinarily widespread with shoppers.
Regardless of the case, it’s extraordinarily seemingly that we’re a good way away from seeing these lenses — and the cameras they’re designed for — in a consumer product. What’s reassuring, though, is that Canon’s patents at least level out the company is considering curved sensor cameras and lenses, merely as every Nikon and Sony are.
