Is it better to shoot with a higher ISO, or use lower ISO and raise the exposure in post-production?

12800 ISO on the Sony FX3 is a native ISO so if you're in a low-light situation it's probably best to use 12,800. And then in post can adjust exposure some more if you have to. Personally if 12,800 is still too dark overall you might want to start adding some lights to the scene.

Need camera recommendations for better low light professional quality.

Sony ZV-E1. You can buy used ones for less than $1500. Camera has the same low light sensor as the A7Siii/fx3.

Introducing the Canon EOS C50 Cinema Camera: Open a World of Cinematic Possibilities

I'm curious what people's thoughts are on this. To me: 6.9K open gate is quite nice, especially if you need different exports. Open gate to C400 is a nice addition too, something the Sony ecosystem is missing. Supersampling to FF 4K is nice, rather than pixel binning or cropping. 6400 ISO is a sweet

Full Frame: a hype designed to get consumers to upgrade

Fair, a really well seasoned opinion. But if you’re looking at it from the perspective of how people actually use these things in the wild, you're missing the forest for the trees. Consumer S35 cameras are not getting the high end features. The manufacturers are trying to upsale you. Is that shitty?

Torn between two cameras!! Sensor size, low light, and post cleanup?

Get an A7Siii used. Best deal by a mile. Especially if they toned down the noise reduction (not sure if they did this though). That higher second native ISO of 12,800 on the FX3, A7Siii, and ZVE1 makes a large difference. Between the FX30 and FX2 definitely grab the FX2, you can save money buy getti

Switching from Canon R7 to Sony FX3 — Cine EI + ISO is confusing me badly

No matter the camera, they all have a ‘base’ iso for their LOG profile. For the r7 and the fx3, that base iso is 800. You should be shooting at that and adjusting either aperture or adding ND to control exposure. Sony has a second base iso of 12,800 - you can shoot at that and control exposure the s

Anyone using a a7V for a B camera?

If you mean for video, I'm using an A7RV (note "R", so not the A7V) for B-Cam because sometime in early summer last year DJs decided everything needs multicam. I bought the A7RV as my main photo camera to replace my Nikon D750 - after buying an FX3 for video it seemed daft to run two lens systems, a

FX3/NAB News

Don’t think so. Used fx3 for over one year, just a few times I switched to high iso. I light interviews, shoot docs and corporate. 80% of time it’s 800/640 iso. With fx30 - I can have 2500 as high iso - which is really enough. Push it little bit more - 3200 - it’s crazy good! Actually it’s like the

FX3 for documentary

Best camera out there for small ob doc IMO. I always liked Sony. First docs were shot with the Z1 which in retrospect was a terrible camera, but at the time it felt magical to go from SD to HD. Sony has a softness to it, that I can’t get with Canon. I like how it renders skin tone better and definit
