It’s mostly a problem of pixel size. The smaller the pixels the less light the pixels get. That means really terrible low light performance. And no software can’t magically make that as good as a pixel 4x the size.
The only advantage here is it allows you to get away with more crime like cropping and digital zoom in brighter lights. That may be an advantage depending on the application.
I’d rather have a 12MP sensor twice that size with some glass in front though for most applications. Far more useful.
- tonyarkles 5y ago> with some glass in front though Since it sounds like you're familiar with the field, any chance you've come across a CS- or C-mount lens with an autofocus motor? I've looked around a bunch and haven't had much luck. The current solution is a full C-mount-to-Canon-EF-mount adapter that has drive electronics in it, but it's eye-wateringly expensive and huge & heavy.
- uuyi 5y agoHaven’t gone near those mounts. All mine is Z mount recently and F mount going back to the dark ages.
- neetdeth 5y agoNever had a reason to use them, but I do recall that Edmund Optics has some C-mount units with liquid lenses in their catalog. The driver modules will allow control over USB or I2C.
- LeifCarrotson 5y agoI've used them in some industrial vision applications with Dalsa cameras. They worked fine, I would have preferred a fixed focus and a manual adjustment when the requirements changed (it was much more difficult to get good real-unit measurements and to compensate for distortion) but they worked fine.
- tonyarkles 5y agoAwesome, good to know! Yeah, the EO Liquid ones came up in my searches too, but I'm completely unfamiliar with that tech (coming from a conventional DSLR world). Thanks!
- semi-extrinsic 5y agoIDK, have you looked at Kurokesu's offerings? https://wiki.kurokesu.com/shelves/cameras https://wiki.kurokesu.com/shelves/cameras
- tonyarkles 5y agoOh wow, I have not come across these folks! Very cool, yeah, these are definitely worth a closer look! Thank you!
- mod 5y agoMy original canon digital rebel XT, I think, is 6MP, and its output can be printed poster size with no visible degradation at any normal viewing distance (like six inches or farther). So yeah, I'll take some good glass and literally any sensor post-2005 (when I paid $1100 for that 6MP)
