B&W in low light and noise issues

You don't indicate in the post, but I'm assuming you must be shooting JPG's. When I want to shoot intending to create B&W, I shoot in raw mode. In doing so, of course, a color photo is produced, which I subsequently convert to B&W, most often using NIK Silver Efex Pro. It would be interesting to take a raw shot and desaturate it one color at a time, and view it at, say, 200% as you do, to see if desaturating has any effect on noise.
Yes, that would be interesting. Maybe "somebody" will post the results .....

When I want B&W shots, I use my little Pentax Q mirrorless ICL camera.
These examples are straight out of camera jpgs. with just a little cropping and sharpening.
I like that with this camera I can set the amount of contrast, high tones and low tones.
All shots were taken hand held using available light in an antique store.
I have lot of other cameras, but none can capture B&W images like this one in camera.

Proof is on the page. No one
needs a Leica Monochrome if
a thumb-sized RGB camera
can do that !

Not especially when the latest Leica Monochrome model is going for a hair under
$5000!

My understanding is that digital noise is of two types: chroma or color noise and luminence noise. In a b & w conversion, only luminence noise is an issue. This may be why b& w looks relatively better at a high iso.

Here’s an example of why I think that. Hope my posting the image doesn’t offend. If so say so and I’ll try to delete it.
What ISO was the photo shot at? There doesn't seem to be any EXIF data.

The OP was asking about high ISO. Three of those shots are at ISO 200, the other at ISO 400. Not hard to avoid noise at those speeds.

Just fyi, here is a link to a post I did of a b&w conversion of a file shot at ISO 28,000.
