Jim Kassen is currently testing the Sony a7RIV and he has discovered that the new a7RIV eats stars just like other Sony cameras. I was considering getting the a7RIV if Sony finally fixed Star Eater, but since they have not I will stick with my a7RIII. Actually they made it worse than it was before because Star Eater starts at 3.2 Seconds now instead of 4!
I’m not going to bury the lede here: ths Sony a7RIV eats stars just about like the a7RIII does.
This is about what we saw with the a7RIII, except that the new behavior starts at 3.2 seconds instead of 4 seconds.
Ugh. My position is that this kind of filtering should be done in postproduction.
You can read more about Jim’s testing here. I wish more photographers would confront Sony about this issue because Sony is the worst offender on the mark. Noise reduction should always be performed in post if it negatively impacts the image, which Star Eater does.
