Old Sensor v New Sensor
Posted: Mon 21 Dec 2015, 08:43
Here's a test which you do not often see on the Internet, with two cameras of different vintages with the same number of megapixels and sensor size fitted with identical lenses. I am not sure that it tells us anything which we did not already know, namely that the improvements have been mainly to shadow noise and high ISO performance rather than outright image quality. The 2008 camera acquits itself remarkably well against the 2015 model. Both sensors, of course, were manufactured by Sony, although Nikon's engineers might well have made different decisions when deciding how to process the image data. Even if Raw files are meant to be as captured directly from the sensor, there are suspicions that manufacturers apply some tweaks. One example is the infamous Raw file lossy compression of recent A7 cameras, which I do not know whether that occurred with the A900 as well.
