Hi Everyone:
I recently produced a 9 minute video that uses extensive slow motion cinematography to capture several species of
Bombus in flight, foraging, grooming pollen and searching for nest sites.
Here is a link to the video in case you haven't seen it https://youtu.be/fQsnPAWQqcI
Several researchers have asked me to describe how I captured such high resolution macro video at ¼ normal speed. Here is a brief summary, but feel free to email me if you have additional questions. My preferred email is

My students and I shoot video with the Canon Full Frame R5 mirrorless camera. This camera produces very high quality 4k video at 120 fps. Since I present the video using the "US standard" 30 fps, this is ¼ normal speed.
Most closeups were shot at 400 mm with Canon's RF 100-400 mm telephoto zoom lens. I shoot with a telephoto lens, rather than a macro lens, so that I can capture images of bees visiting flowers 3-4 meters away. The 4k video is so detailed that I can further crop the image to provide an even narrower field of view. So I typically do 30-50% video crops using Powerdirector 365 software to fill the frame with bee and flower.
Our study site is ½ mile from Lake Michigan, and there is always at least a 10 mph wind. Fortunately the R5 camera has outstanding in-camera stabilization, ensuring smooth telephoto video. We shoot most of our video handheld, but sometimes use a monopod on very windy days.
One thing we do a bit differently than most people shooting slow motion video is that we use a shutter speed of 1/1000th sec to minimize motion blur. Thats why you can see the bumble bee wings flapping so clearly.
