Canon patent for 200-600mm f/4.5-5.6 superzoom for full-frame DSLRs

 

Canon patent

200-600mm f/4.5-5.6

Canon patent for a superzoom lens for full-frame DSLRs, an EF 200-600mm f/4.5-5.6 lens.

As always with patents, you can’t be sure if the described product will hit the market. However, the optical formula in the patent reminds the Sigma 150-600mm F5-6.3 DG OS HSM lens, and given how well the latest Sigma lenses perform (given the price), I wouldn’t be suprised if Canon decides to strike back. I think such a lens would be welcome by the community.

Canon’s 250MP APS-H sensor is based on column parallel ADC technology

canon 250mp sensor

Do you remember the 250MP sensor Canon showed off last year? I am pretty sure the sensor is based on column parallel ADC technology.

There is an interesting paper presented at ISSCC 2016 (2016 IEEE international Solid-State Circuits Conference) by a team of Canon researchers, with title (thanks Richard)

An APS-H-Size 250Mpixel CMOS Image Sensor Using Column Single-Slope ADCs with Dual-Gain Amplifiers” (H. Totsuka, T. Tsuboi, T. Muto, D. Yoshida, Y. Matsuno, M. Ohmura, H. Takahashi, K. Sakurai, T. Ichikawa, H. Yuzurihara, S. Inoue -Canon, Kawasaki, Japan)

Unfortunately the paper will be presented in January, when the conference takes place, and is not yet available to the public.

I posted a few days ago that Canon filed a slew of patents regarding column parallel ADC technology, and that I got a hint this technology may be implemented in future Canon pro bodies (which in the meantime has been reposted by some sites). I am currently studying more Canon patents that all refer to column parallel ADC technology. Given the sheer amount of such patent, I think it is safe to assume that Canon has some plans with this technology.

2016 will be an exciting year for Canon, with new pro bodies coming (EOS 5D Mark IV and EOS-1D X Mark II) along with the EOS 6D Mark II and possibly a full-frame mirrorless camera. It’s too early to speculate on which cameras Canon will feature a sensor with column parallel ADC technology, but they will. I believe we may see this technology first on the EOS 5D Mark IV and EOS-1D X Mark II.

The video below (by Fotografiapuntoit) gives an overview on Canon’s 250MP sensor. Stay tuned for more…
