Sony A7s ISO Test |
ISO 3200 vs. ISO 409600 |
| |
Test by Sinan Ozturk |
|
Sony A7's maximum ISO is a jaw droping 409600.
These shots are taken in pitch black darkness (in which camera was able to autofocus on its own) with its maximum ISO vs. ISO 3200.
Yes, I admit ISO 409600 is unusable but come on, its ISO 409600! Even my professional photo editor software is not able to handle it properly, it thinks a camera can not shoot with so high ISO and its stuck in 65535.
With it camera shutter speed was 1/40s even in pitch black which makes even hand held shots possible. [Review by Sinan Ozturk]
