Buy a SLR body to T2 lens adapter, remove the threaded inner ring that is the T2 component, then stick this thing into it and mount your SLR on top of your trinocular microscope. This adapter is made specifically for a Pentax PK style mount and flange distance, so Nikons may not focus correctly, but Canon should. It's pretty cool with HDMI and liveview, but also great for taking photos/video of your micro-world. The adapter was originally designed to fit the 22mm C-mount tube that comes with this microscope, but that flange distance is intended for much smaller sensors, so it would have sucked. The only way to get the required APS-C flange distance was to mount the "adapter" directly onto the top of the microscope after removing the 22mm tube/C-mount components. The title isn't completely correct and I don't care right now. It just sits on top of the microscope, and will fall off if you bash something too hard. No doubt I'll stick a locking screw in it eventually after I figure out what else sucks and iterate the design. But for now I'm using it as is. The flange distance seems to be correct for the camera to be in focus at all focal lengths using WF10x/20 eyepieces, 0.5X auxiliary objective on top of the standard objective. You just need to adjust the camera to focus, then adjust your eyepieces to also focus. After that you should be generally correct at all ranges. https://www.aliexpress.com/item/3-5X-7X-45X-90X-Simul-Focal-Soldering-IC-repair-Trinocular-stereo-microscope-With-big-boom/32911809554.html https://www.aliexpress.com/item/Foleto-T2-Mount-Telescope-Lens-Adapter-Ring-to-for-canon-EOS-nikon-SONY-M42-olympus-pentax/32899435466.html
