New sensor technology coming to future Canon pro bodies (EOS-1D X Mark II)?

Column parallel sensor (taken from Canon patent)

I got some hints that Canon may implement a new sensor technology in their future pro-level DSLRs. The Canon EOS-1D X Mark II was also mentioned to possibly get a new sensor tech.

Thanks to reader Richard, we know that there is a slew of patents referring to column parallel sensors, a technology Sony is using on their EXMOR sensors. Quoting one of Canon’s patent applications, a column-parallel A/D converter is…:

a method for improving precision in analog-digital conversion […] of pixel signals. The A/D converter includes a first A/D converter (first processing unit) and a second A/D converter (second processing unit), and the first processing unit performs A/D conversion to generate higher-order bits of digital signals and then the second processing unit performs A/D conversion to generate lower-order bits. The first processing unit performs the first A/D conversion by comparing an analog signal to be converted and a reference voltage. The second processing unit starts charging a capacitor by a constant current source according to the result of the comparison performed by the first processing unit, and ends the charging in response to an edge of a clock signal (a rising edge) supplied immediately thereafter. Then, the second processing unit maintains the voltage for the capacitor and performs the second A/D conversion.

According to information passed over to me, Canon filed not less than seven (7) patents referring to column parallel sensor technology. A bit too much to believe Canon does not have some (big?) plans with such a sensor technology. Therefore, suggestions stating the Canon EOS-1D X may feature a new technology sensor may point in the right direction.

One of the patents is US2015/0341577. It refers to a column parallel sensor, and it seems to describe a method to get more dynamic range from shadows.

I am currently studying the other patents and will disclose them soon. Stay tuned…

Canon patent for 50mm f/3.5 IS macro lens for full-frame mirrorless cameras

canon patent

Canon patent for a neat lens. An image-stabilised Canon 50mm f/3.5 IS maco lens for full-frame mirrorless cameras. And yes, there are rumors about a Canon full-frame mirrorless camera. The latest of those rumors says Canon’s full-frame mirrorless camera has been delayed because of mount-related issues.

Canon EF 50mm f/1.4 and EF 50mm f/2.5 compact macro listed as “production ended” at Canon UK

Canon EF 50mm F/1.4 And EF 50mm F/2.5 Compact Macro Listed As “production Ended” At Canon UK

Both the Canon EF 50mm f/1.4 and the EF 50mm f/2.5 compact macro lenses are listed with a “production ended” tag at Canon UK.

Both lenses have not yet been officially discontinued by Canon. However, the EF 50m f/1.4 is rumored to get replaced, and there is a pertinent patent for a possible EF 50mm f/1.4 II. The Canon EF 50mm f/1.4 USM was released back in 1993. A replacement could be on its way. The EF 50mm f/2.5 compact macro is a niche lens, I wonder what is going to replace it, and if Canon is going to replace it.
