Olympus OM-D E-M5 image stabilization can be fined tune to match the focal
length of the lens attached. For example, in the classic wide-normal range
the choices are 30 35 40 48 50 55 and 65mm's.

Well, there are a bunch of 35 40 50 and 55mm's of course. 30 is not unheard
of. But 48? And 65? Olympus themselves used to have several original-Pen
Zuiko 38 and 42's and for these you will have to select 40mm instead. I have
three 58's for which 55 is the closest match. Instead of offering these more
practical FL's, Olympus decided to go with the obscure 48 and 65mm's.

Am I missing something? Question

A lens labeled does not mean the the focal length of the lens is exactly 50mm but is close to it. Two exceptions are the mir-1 2.8/37 and the Tair-11 2.8/133.

Perhaps these settings are intended for the long end of the OM Zuiko 24-48mm, and the short end of the 65-200mm?
