A7mkiii iso invariance test
I read a page saying that the A7mkiii uses iso invariance (along with other models) meaning you can shoot astro as very low iso's and just push the exposure in post and get the same noise as a higher shot. I think I have this right. Anyway, I gave it a shot last night.
iso 800 @ f2.8 for 15 seconds pushed exposure in post.

12 shot stacked image using Sequator iso 8000 @ f2.8 15 seconds

Both are absolutely beautiful shots. I kinda like the last image the best.
