I tried the same a few years ago with the original Blackmagic Pocket (for video, no focus stacking). You can get pretty good microscope lenses cheaply on eBay and the rms-m42 adapter is cheap. https://youtu.be/JwIDTtu8XnA https://youtu.be/JwIDTtu8XnA A lot of shakiness at that magnification level though (had to stabilise in post) and the depth of field is razor thin - this is where focus stacking with stills helps a lot. Optically I’ve found regular super-macro lenses are better (2:1 or more)

This looks fantastic. I've been wondering if it's possible to record 180° stereo (for VR), in "close" to macro?

  Thanks! Good question - the FOV with macro lenses would not be anywhere near 180°, though I'm sure you could distort the video to wrap around you. Stereo macro seems to be a thing with stills, at least - https://www.flickr.com/groups/2158359@N23/pool/with/35314464236/ https://www.flickr.com/groups/2158359@N23/pool/with/35314464...

    Mhm.. you can't wrap a still to 180°, that is not the same effect. The focal point would need to be right where you want to take the shot. I'm more thinking of something like that: https://www.amazon.com/Industrial-Synchronized-Security-Counting-Stereoscopic/dp/B07MFTLQVT https://www.amazon.com/Industrial-Synchronized-Security-Coun.... But the lenses need to be closer together and be able to stay in focus at a much closer range. Maybe IMAX had done some macro (insects) stereo documentary.

      what I meant to say is with macro lenses the FOV is narrow because of the high magnification, and with VR you typically want (very) wide angle lenses. 180 stereo VR is usually shot with two cameras (in portrait) with fisheye lenses, I've worked on a couple of these shoots. The minimum focal distance on these lenses can be pretty small (a couple of cm) so you can get sort of a "semi" macro effect, though not quite the same
