I have used this same set= up to film butterfly behavior, and therefore thought this might be of inter= est. Here is a link to the video in case you haven't seen it https://www.youtube.com/watch?v=3DfQsnPAWQqcI Several researchers have asked me to describe how I captured such high reso= lution macro video at =BC normal speed. Here is a brief summary, but plea= se feel free to email me if you have additional questions. My students and I shoot video with the Canon Full Frame R5 mirrorless camer= a. This camera produces very high quality 4k video at 120 fps. Since I = present the video at 30 fps, this is =BC 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. I use sing= le point autofocus. The 4k video is so detailed that I can further crop th= e 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 wetland study site is =BD mile from Lake Michigan, and there is always = at least a 15 kmph wind. Fortunately the R5 camera has outstanding in-came= ra stabilization, ensuring smooth telephoto video. We shoot most of our vi= deo handheld, but sometimes use a monopod on very windy days. One thing we do a bit differently than most people shooting slow motion vid= eo is that we use a shutter speed of at least 1/1000th sec to minimize moti= on blur. Thats why you can see the bumble bee wings flapping so clearly. Again, please feel free to email me if you have further questions about the= use of slow motion video in field studies of animal behavior.
