Rabbits are relatively common sight in the Northern France, but it's not easy to convince them to be the models.
The best time is to see them is about 2 hours before the sunset, while they are eating and don't pay too much attention.
I used Sony a6000 with sel55210 lens.
If they are standing still, 1/250s is a reasonable shutter speed, but if they run, it's necessary to use 1/1000s.
In contrast to other lenses, it's ok to use sel55210 with fully opened aperture concerning the resolution in the central areas of the picture (f/6.3 - f/11.0 is pretty much the same).
The sweet spot for the peripheral region is about f/8.0. source
