Raptor vs Gemini for Lowlight

[Alex Werjefelt]

Anyone have any input on how the Raptor stacks up against the Gemini for low light? For example 3200 ISO at 8K on raptor scaled down to 5K vs Gemini in at full res in lowlight Lowlight mode at 3200.

We looked at this as we have both and where considering getting rid of our gemini...

If you are happy with the different Dof of your proposition they are really not far off BUT I'd really recommend a test as they feel different.

I feel when downsampling the Raptor as you describe the Raptor is just smidgen less than a stop out but it also benefits from better highlights. Also I feel if you use a soft downsample AND a tiny bit of NR you will take away any advantage the Gemini has..

and do remember you will have different Dof for the same FoV

and much larger files

Raptor's compression does really different things to noise than the Gemini and it also has sharper/better pixels to start with so together this can give the impression of sharper noise.. (This feel wrong but a test may show you what I mean)..

For ISO 3200, I can't see either option being too far off from each other, ISO 3200 performance has been pretty good for a while with some noise reduction from the likes of Neat Video. Now, ISO 6400 would be the real battleground but, practically speaking, I would just switch to a Sony mirrorless camera for that.

I had to boost a clip to 6400 the other day and added a Neat Video node. Results were pretty damn good, but I still felt like I lost a ton of color info.

You have to take into account that Geminis smaller sensor allow for s35 instead of FF lenses. S35 lenses with their smaller projection can be made faster than FF lenses. Faster lenses that brings more light to each pixel.

It maybe not be practical but in theory / technical terms you could add a speed booster to the Gemini and use the same lens infront of it as you got on Raptor and get the same DOF and FOV on both and more light per pixel on the Gemini.
