Looks really great and sharp. Though it almost looks like it was shot in 500fps and slowed down to look like 1,000, is that because of the motion blur?
I'm still a lens noob but is that motion blur effect caused by the F4 aperture or the 357 degree shutter?
That is just the (basically almost full) 360 degree Shutter, that makes everything look like that.
That is also the Reason, why the common reccomendation is to use 180 degree shutter. This gives some amount of motion blur, but not too much, also 180 degree Shutter was used in Cinema Movies for a very long time, so we are very much used to the look of it.
If you go far below 180 degree, like, lets say 18 degree, your individual Frames will look Sharper, but the clip istself wont look as Smooth. For Pans or Fast Camera Movements, also anything in The Frame that moves Quickly will Look choppy. This is often used in Action Scenes or other Very fast Scenes to make it look more intense or harsh (maybe not alway as extreme as 18 degree, maybe more like 90 or so).
If you go way above 180 degree, like here 360 degree, everything just blurs together and it also looks odd. Thats why 180 degree is mostly preferred for Cinematic Shooting.
For Science and such, there may be other factors that come into play when choosing an Shutter angle. For example, if you know there will be a lot of very fast moving Objects, and want to actually get Sharp images of those, while in the air, you want your Shutter angle as low as possible and so on...
