ISO 50 and silent mode for A7S

[detlef]

Hello.

 

What are the bads if using ISO 50 or silent mode? Does it cost dynamic range or image quality? Some functions does not work with this settings, i know. But does it affects image quality?

 

Kindly regards.

ISO 50 can cause blur if the subject is moving.  This can be used as an effect.

 

Silent shutter can cause a curved distortion on moving things, never in a good way.

Thank you JCC.

Silent shutter also reduces IQ and can cause banding under different artificial lights.

Strangely, my A7s never suffered from the distortion problems using silent shutter, but my A7r II and A6300 do, the A7r II being the worst.

I think it's due to sensor size (pixel density).

Yes, both ISO 50 and Silent Mode can negatively affect image quality.

 

Jim Kasson has done some really technical research on what makes the Sony A7x cameras tick.  

 

Here is a post on the extended ISO.

And regarding increased read noise in Silent Mode

Somewhere (DPReview?) I vaguely remember reading about bit depth dropping when in Silent Mode as well.

Silent mode works nicely on my A7s mod. So much so that i don't use the noisy mode anymore i must say.
