Fortunately, there are two very affordable long focal length frog photography lens options available. Canon's RF 600mm F11 IS STM and RF 800mm F11 IS STM Lenses are able to nicely capture these subjects from non-threatening distances.
These lenses are simple to use — F/11 and be there simple.
Having a single aperture setting available simplifies exposure settings, and the relatively deep depth of field makes keeping the subject in focus easy.
These are aspects that casual photographers and beginners, including kids, can appreciate.
