DSLR to 4/3

Right, though I think what (s)he was getting at is that neither have a huge collection of dedicated crop sensor lenses (DX/EF-S).  This is a bigger problem at the wide end where, for instance, Canon really has only a single OEM solution (10-22, 16-35 equiv).  I don't know what Nikon's DX offerings are.

With few exceptions, the high end lens lineup for Canikon is designed with full-frame in mind.  Sure I could use my 24-70L on my 550D, but it gave me a very different FOV that it was originally designed for (38-112 equiv).

In the end, it's not a huge deal, but now that I'm on m4/3 it's refreshing to have the lenses designed specifically for the sensor's crop factor.  The OCD me likes that there's a 12-35 and 35-100 which are exact equivalents of their bigger FF cousins for Canon and Nikon.
