Just a couple of quick notes.
Keep in mind different cameras sample their sensors differently. Canons for example use selective line sampling, so it will sample the image from every few lines of the CMOS. This can cause more artefacts on textured surfaces, which are better ironed out on higher end models. Think 5, Dx. I understand some models from Panasonic and Sony use full sensor sampling that has made them popular for wildlife filming in the past, but they generally deliver a more ENG look that I don’t like compared to the less detailed smoothness of Canon.
Also there is a lot of scope for time-remapping using frame interpolation. Film a bird taking off? As long as you use a high enough shutter speed (I think min 1/640) at the highest frame rate (I use 60p because in the internet age the old 25/29.4 is a bit redundant and the 24p mode cameras offer is marketing), you can then use software to approximate the effect of a proper high speed camera. I’ve yet to experiment much with this though.
