Sony cameras are known for being excellent in low light, and the a7 IV is no exception to this. However, one of the primary reasons this is true is because cameras like the Sony a7 IV contain a dual ISO system that allows the camera to produce a clean image at both a low/base ISO, and a high ISO value as well. And while this system operates similarly to other Sony cameras with similar dual ISO setups like the a7S III, FX3, and more, the dual ISO values in the a7 IV and the overall difference between these low and high values is completely different.
In this technical tutorial video, I'll go over how to find both the base ISO and high ISO values in the a7 IV, showing two different ways you can determine the high ISO based on its low ISO value. I'll also cover several important points, such as the relationship with these dual ISO values and overall picture profiles, gamma curves, etc. in the camera, and what practical ISO values you can expect to get usable results with in the camera.
Feel free to check out the many other Sony a7 IV videos on this channel, and/or my existing video on the a7S III and FX3's dual ISO system. Let me know in the comments below if you like technical tips and tricks videos like this, and if you have any questions!
