Sony RX10 V: Sensor Performance

For example, an A7 4 with a Sigma 20 to 200, albeit for about 500 bucks more, or an A6700 with a Sigma 16 to 300, both of which will deliver cleaner images at high ISOs with greater dynamic range thanks to their bigger sensors, especially the A7 4

There are cameras that offer even more range, but all of them are based on much smaller sensors, so you pay a price in terms of image quality, if any survives the heat haze.

Here, you have a 20.1 megapixel stacked sensor that is 1 in.
