Canon announced on august 31 that they’ve developed the worlds largest CMOS sensor measuring a whopping 202 x 205 mm. Thats the beast up there to the left of a full-frame CMOS chip. Apparently this thing is so light sensitive, it is able to capture great images at just 100th of the light required by my EOS 5D Mark II full frame camera. Knowing how good a performer my camera is in this regard, its just mindblowing to think of the capabilities of a sensor this large. For instance, this sensor is able to do video at 60 frames per second at light equivalent to just 0.3 lux. That is one third the light off a single candle. At 60 FPS.
My Canon 40D has an impressive 6.5 second frame rate. Fast enough for the occasional animation shoot. About a year ago, I got acquainted with Casios Exilim Pro EX-F1. It can do 60 FPS in full resolution, and up to 1200 FPS in a small format (336 x 96). Today, we use this camera for rocket engine tests.
Even this speed is effectively dwarfed though, by the Steam Camera. Capturing 6 million FPS(!) @ shutter speed of 440 trillionths of a second, and, for now, comprising of only a single ‘pixel’, this detector is potentially useful for analyzing flowing blood samples in the medical field.
A quick quote from the BBC article explains a bit of the underlying science:
It works by using a fast laser pulse dispersed in space and then stretched in time and detected electronically.
So thats clear, then.
DxO, makers of DxO Optics Pro and DxO Analyzer has revealed a new webpage with RAW image quality comparisons based on their analyzing tool. The webpage gives an easy overview of camera performance across brands and price based on a number of user selectable criterias, and is free to use.
The Canon EOS 5D Mark II is scheduled to ship by the end of November 2008, at least in the USA, according to Chuck Westfall, Technical Advisor at Canon USA.
I dont know about you, but I’m looking forward to get my greasy hands on one of these babies.
