Two-body setup for Disneyland/Travelling

and the Oly 45/1.8 or the Pany equivalent.  Two small lenses.  I bought the small Oly FL-LM3 flash that was originally marketed with the E-M5MkII, modified it and use it in lieu of the flash that came with my GM5.  Very small and works fine out to about 10-12 feet.

When I'm doing serious travel photography, I have an E-M5 + 12-40 and the GM5 with the 45,  but that's waaaay too much for what you want.

And the poster who talked about the intense California sun and the need for an EVF was spot on.  I live in Phoenix, and a camera without an EVF is pretty much useless here.

KISS philosophy...Keep It Small and Simple...applies.  If the camera gets in the way of the fun, well....that's no fun.
