THIS is what innovation looks like, and Sony’s leading the charge.
Do you REALLY want to complain that Sony is already releasing a Mark II version of the A7?
Sony has been innovating, continuously improving and putting itself on the line in the marketplace at a torrid pace over the last several years, and we are richer for it.
This is what kaizen is all about, a term first popularized in the U.S. with the Toyota Production System during a period which saw Toyota rise to dominance in the auto industry.
The irony, of course, is that the process originated with American engineer and statistician W. Edwards Deming.
No matter. The idea of a digital video sensor in an A7s Mk II – or in any other camera — which has a base ISO of 5120 and a dynamic range one to two orders of magnitude greater than the best cameras we have today is… startling.
Film doesn't have 21 stops of dynamic range.
And you think the A7s is the low light king? If the new Sony sensor is real, it will make the low light performance of the A7s – and that means EVERYTHING else as well — look like Super 8 film that fell out of the back of the family station wagon and unraveled all over the driveway in 1965.
If it’s real.
New Sony Sensor: Offers 21 Stops of Dynamic Range & a Base ISO of 5120
Via No Film School:
To recap why this sensor could theoretically provide a massive leap forward in all aspects of image quality, it uses a new technology called Active Pixel Color Sampling that allows each pixel to sample RGB data individually, which eliminates the need for color filter arrays and complex debayering processes. Because of this technology, Sony can use roughly 1/3 of the amount of pixels to output an image with the same resolution as a much more pixel-dense sensor of the same size. This also means that the individual photosites can be much larger, which theoretically will allow for tremendous gains in low-light ability and dynamic range, depending on how the sensor data is processed.
That leads us to the more recent developments. The fine folks at the Sony Alpha Rumors Forum were recently sent a few documents that provide more details about how the sensor works and how it is theoretically expected to perform in terms of ISO and dynamic range. Here is one standout chart from their post which shows latitude
Yes, you read that correctly. If this graph is factual, and that's a big “if,” Sony's new sensor will have a base ISO of 5120 and slightly more than 21 stops of dynamic range at that sensitivity. Those specs alone are enough to leave most of us salivating, but it's important to keep a few things in mind.
