Re: Image Sensor & Lens Patents from Canon
On chip A/D is one of the biggest magic ingredients that make Sony EXMORs as good as they are in the read noise department, so lets hope that happens.
On the other hand, I was really hoping for my 15-70/2.8 IS with Sigma-18-35 level mechanics. A good many years ago Tamron actually made a 28-105/2.8 for full frame which works out to about the same on crop, so with today's technology and on a smaller format a 15-70/2.8 would be def. doable, and would be a godsend for run and gun video esp on a 4-5K cam where you can crop in quite a bit, almost like a 1.4x-2x TC, giving a range close to an 24-200 (135 full frame stills) on crop, covering a huge variety of docu-style situations. A 15-105 f/2.8-5.6 would likely get pretty close to a 15-70 f/2.8-4 over that focal range, and it would be really useful as a run and gun outdoor lens for true cinema cams, and maybe even indoor too for C-series and Sony cams that perform well at high ISOs when stopped down to a constant f/5.6 or so all the time, but I'm not sure I can justify it on top of my existing f/2.8 zoom set relative to the Sigma 18-35, unless it is closer in price to the 18-135 STM rather than the Nikon 15-85/2.8-4. And I'd almost rather have something like that than the Canon, or better yet a 15-105/2.8-4.

MORE DR and less shadow noise would be a NICE to HAVE?

Re: Image Sensor & Lens Patents from Canon
Getting back to the patents. Can anyone here explain how this sensor design differs from previous ones. According to a post above, Canon has used on-sensor and off-sensor in the past. So I am wondering what is different now.
Reading the patent is... difficult, to say the least.
From what I gather, they are using a ramp-compare ADC with a counter(timer), and doing 2 columns at a time with a delay before the next 2 columns. Is that a departure from how they have done it in the past?

And even Maeda laments Canon's slow progress.

Came on here to look for info on latest patents and informative discussion. Found hilarious meme's of Jean Luc instead. Was not disappointed! Hahaha! Love it! ;D
