Sony A7 vs. Sony RX100 mk2 ISO Comparison

Comparison # 925
Camera ISO Comparison
Sony A7 vs. Sony RX100 mk2
	Comparison by Deniz Mert ICOZ

PhotoAgainst Photo Editor's Comment: Sony RX100 mk2 is using a back light illuminated sensor and just like many other cameras with that sensor, its base ISO is actually 160, not 100.

It can go as low as ISO 100 but its best performance is at ISO 160. On the other hand A7's base ISO is 100 so first comparison is with their base ISOs, hence ISO 100 vs. ISO 160.

And the last comparison reflects their maximum ISOs which is 25600 for A7 and 12800 for RX100 mk2.
