Canon Patent: 50mm f/1.8 Image Stabilized Lens

Egami (translated) spotted a Canon patent for a 50mm lens with f/1.8 and image stabilization. The patent does in some way fit with a rumor regarding a new image stabilized Canon 50mm lens said to be announced in 2013. Another Canon patent for a 50mm lens I reported about can be seen here. Canon has three 50mm lenses in their line-up: the EF 50mm f/1.2L, EF 50mm f/1.4 and the inexpensive EF 50mm f/1.8. The lens described in the patent will not replace the 50mm f/1.2L nor the 50mm f/1.8, most probably it will replace the 50mm f/1.4 (I don’t think Canon will add a fourth 50mm lens to their line-up).

    • The overall length of the lens 76.78mm
    • BF 37.84mm
    • 8 pieces of 7 lens configuration
  • Canon patent
    • (Optical system of the anti-vibration unit is located between the aperture and the front lens group) and vibration-proof

Canon Rumor: Does Canon’s 75MP DSLR Have A Non Bayer Multilayer Sensor?

75MP

That’s what the latest Canon big megapixel rumor suggests, that the rumored 75MP are a ‘total usable photosite’ count and refers to a non Bayer multilayer sensor. Some time ago I reported a Canon patent that refers to such a sensor (this patent). Previous cover of the rumor here.

Your DSLR May Soon Act As A Light Field Camera with KaleidoCamera

German researchers of the Saarland University presented a paper describing an accessory that transforms your DSLR in a Lytro-like, refocusable light field camera. This opens new perspectives for multi-spectral and high-dynamic range photography. The prototype will be presented at the Siggraph conference and exhibition in Anaheim, California. The prototype, named KaleidoCamera, is an accessory that fits between the lens and the camera body, and has a beam splitter that enables the camera to record various differently filtered images. Those images are then available for further processing. The paper abstract:

We propose a non-permanent add-on that enables plenoptic imaging with standard cameras which we refer to as KaleidoCamera. Our design is based on a physical copying mechanism that multiplies a sensor image into a number of identical copies that still carry the plenoptic information of interest. Via different optical filters, we can then recover the desired information. A minor modification of the design also allows for aperture subsampling and, hence, light-field imaging. As the filters in our design are exchangeable, a reconfiguration for different imaging purposes is possible. We show in a prototype setup that high dynamic range, multispectral, polarization, and light-field imaging can be achieved with our design.

The paper A Reconfigurable Camera Add-On for High Dynamic Range, Multispectral, Polarization, and Light-Field Imaging is available for download.
