Canon Lens Patent Shows 24-600mm f/2-3 Optics for 1″ Sensor

Canon Patent for 24-600mm f2-3 Lens for 1-inch Sensor

Canon applied for a lens patent that was published back in December and featured a number of different optical embodiments, including a high-magnification zoom lens for a 1″ sensor format.

In the patent, the true technical measurements of the lens reveals an 8-180mm zoom with an aperture range of f/2-3. Adjusting these numbers for the roughly 3x crop factor of a 1″ sensor and rounding them off for marking purposes, you get a 24-600mm f/2-3 equivalent lens.  [Read more…]

Lens Patent for Nikon 1 70-300mm f/4.5-5.6 Lens

Nikon_70-300mm_Lens

A recently published patent application reveals a new version of the 70-300mm f/4.5-5.6 VR lens for the Nikon 1 system. The optical formula in the patent focuses on make the lens more compact to accommodate the smaller Nikon 1 system.

Of course, the patent was just published on only filed back in October 2014, so don’t expect the lens anytime soon since the current version just started shipping a few months ago (it was announced in March 2014 alongside the Nikon 1 V3) and is still not regularly in stock (currently backordered at B&H).

Who says you can’t put an awesome optical viewfinder in a compact camera?

Certainly not Fuji, who has been knocking it out of the park with cameras like the X-T1 and X100s lately.

In a recent US patent application, Fuji seeks to patent an optical viewfinder that has optical elements inside and zooms to match the focal length of the camera’s zoom lens – or as Fuji calls it in the patent application a “Real-image zoom viewfinder.”  [Read more…]

Canon is Developing a New Organic Compound for Sensor and Optics Technology

Canon-7D-Sensor

Canon’s next big move in sensor technology might be a new organic compound that maintains a high level of transparency and is uncharacteristically efficient for light transmittance as far as organic electrochromic compounds go.

Rumors have been swirling in recent weeks about Canon’s next big thing and the key feature being tossed around is that Canon has some killer new sensor technology. As I spent a good chunk of my weekend reading Canon patent applications (because I’m more than an average camera geek), I came across a trend of sensor technology and some chemical engineering patents that relate to image sensors.
