…or “The Saddest Little Mouse”.
(Anyhoo, you see what I did there?)
Saddle + Mandler = Sandler.
(Or Sandle. Or Maddle…I don’t know).
In any case, the mouse is sad, because the lens is front-focusing (yes, on a few bodies…) and needs to be re-calibrated.
Should never have sold the first one to begin with.
