Difference between ISO 100 and 6400
1

I have here a comparison, with two diametrically opposed cameras
https://www.flickr.com/photos/maoby/albums/72157716593624193
Two cameras that I like a lot
The Nikon D3s (2009) and the Sigma sd Quattro H (2016-17)

The Nikon D3s (2009)
12.1 MP (4256 x 2832) sensor
Price: $ 5,200 USD
Photos taken with the nikkor AF-S VR 24-120mm f / 4 G ED N
(with a multiplication factor of 1.0) FX
200-12800 (100-102400) H3 ISO

______________

Sigma sd Quattro H (2016-17)
25.56 MP (6192 x 4128) sensor
Price: $ 1,200 USD
Photos taken with the Sigma 24-105mm F4 DG OS HSM Art
(with a multiplication factor of 1.3) APS-H
ISO 100-6400

I generally find that the Sigma H produces superb results, but only at ISO 100
subsequently, it can become catastrophic!!

N°22 Nikon D3S (100 ISO)

N°22 Sigma Quattro H (100 ISO)

N°22 Nikon D3S (6400 ISO)

N°22 Sigma Quattro H (6400 ISO)
