Mechanic 8k Sony IMX678 microscope camera worth getting for micro soldering?

[d00m178]

Thank you for your opinion!

I currently use a magnifying lamp on a swing arm at my workbench, but I'd like to replace it with a digital microscope that displays the image on a monitor. I think that setup will be much more comfortable for soldering and PCB work.

So I'm still looking for advice about these newer IMX678 camera modules and the other components needed to build a DIY microscope from AliExpress.

Also, is this the right topic to ask questions like this?

On AliExpress I found:
* a black-box no-name camera:

* and the gray HAYEAR HY-6210S:

If you want to solder with it, I would not be using a 30fps camera.
You don't need polarizing filter for anything other than IC identification, IMO. I guess it can be used for inspection but a quality light also works.

So, I assume that an IMX678 camera which only supports 4K at 6 fps, but runs at Full HD 60 fps, is not a better option for soldering and is simply overpriced for this use case.

Because of that, would it make more sense to buy the cheaper IMX415-based device instead?

To me it would make sense, I'd prioritize: latency, fps, light sensitivity. But I don't use a digital microscope for soldering.

Maant XJ03 apparently is using IMX347, that one might be good too.

IMX347 is Starvis 1. IMX678 is Starvis 2 and roughly 5 years newer. I expect better contrast/low light capabilities. And the IMX347 is not 4k (it's 2712×1538 effective), the IMX678 is (3856×2180 effective).

Yes I know, its 1080p60, I'd take 1080p60 over 4k30 for soldering.
If you can find IMX678 at 60fps for a reasonable price, then its obviously going to be better.

Hello everyone.
By popular demand from the working people, here are the guts of the Bresun 4K 60 and 4K Max microscope camera.
Camera Outputs true 4K at 60 fps via HDMI.

Interesting to see.

this is my Maant xj2 from the inside. Pretty much the same (it also runs the same software/menu structure&features)
I don't have the means (or knowledge) to dump the firmware




this underside had some horrible chinesium flux (white residue) that couldn't be removed with alcohol, but did remove with contact cleaner.

the thing I don't like about this camera is that it only has tripod mounts on the sides, and not one on the top. It makes it awkward to mount it on a little tripod (I use it for more than just pcb repair). but that Bresun is the same in that regard.
And the graphics on it are a bit...meh, but I'm sure a bit of acetone or something could probably (dis)solve that (not that it's that important though)
But the price was good

Hi all, folks Im as wel shop around for new camera, does anybody know where to get in China Bresun 4 k max camera? I have a friend in China but he never found this model at Taobao. From the Nanofix comparison video I did like Bresun the most: best pic quality out of the box.
