Slower aperture lens on APS-C / Crop vs f/2.8 lens on Full Frame body
With a fast aperture lens, i.e. the Canon EF 300mm f/2.8L IS II USM super telephoto lens, its much easier to blur the background - and when paired with a full frame body its almost effortless (ito panning and the work required for rendering background blur compared to an APS-C / Crop sensor body and / or slower aperture lens).
The end result (ito background blur) may look very similar, but there was much more tracking, pre-focus and panning involved with the 1st image.
Distance between foreground and background / depth of field for both images are very similar - and captured in the same area in the Milnerton Lagoon, Woodbridge Island, Cape Town.
Due to the the larger sensor of the full frame body I was able to crop the 2nd image to more / less the same dimensions as the 1st image.
