Figured this might be useful for people here (especially myself) wanting to take better bunny pictures.

Article has stuff about rabbit behavior in general, which photographers would probably want to know so they could know what to take pictures of and where and when to find them doing it. Article also has plenty of adorable rabbit photographs!!

There is stuff all about the setup in the article, but the quick-digest technical information that I think certain phone camera users might be able to also take cues from is:

… a chance that rabbits might come quite close. A 300mm lens might be sufficient for frame-filling shots, but generally I have found that a 500mm f/4 or 600mm f/4 lens (on a full frame camera) is required.

My strategy with exposure is to start with an ISO of 800 and use my lens aperture wide open. This blurs the background and gives me the fastest shutter speed possible. Even for fairly static portrait shots of rabbits, a shutter speed of 1/500th of a second or faster will be helpful when using a long lens supported on a tripod or beanbag.

If you want to be ready for some sudden action, the shutter speed should be 1/2000th of a second or faster.
