Why I think the Sigma fpL can be a very good tripod camera

Yes, but does the electronic only shutter not make the camera unviable for a lot of what the. Americans would call use cases?

It is bad for hummingbirds in flights and swinging golf clubs .
Seriously, photographing fast-moving subjects, handholding with long lenses, and artificial light banding are the main issues when using the electronic shutter on all cameras, except a9/a1.
For landscapes, still and slightly moving subjects, macros, and many more, it works fine. I measured the readout speed to be the same as a7rIV (as reported by Jim Kasson). AFAIK, a7rIV owners are regularly using the electronic shutter. Note that the readout speed is faster in 12-bit mode.

Guillermo. How did you shoot, stack and process your Sony ISO6 files? Thanks.

Guillermo. How did you shoot, stack and process your Sony ISO6 files? Thanks.

I just shot them in a row with a remote shutter, processed them using a language called R, and used a script calling dng_validate to build the output DNG file:

• The process is explained here: https://www.overfitting.net/2021/05/apilado-por-media-simulando-iso-ultra.html
• The source code (pretty straightforward, just average the RAW values): https://github.com/gluijk/dng-from-tiff/blob/main/exercise2-meanstacking/meanstacking_DNG.R
• The script to build the ouput DNG: https://github.com/gluijk/dng-from-tiff/blob/main/dngmaker.bat
