>>3090219Depends what you want.
Just a heads-up: Panny is good for videos, but if your focus is photography, go with Olympus.
I use some old adapted lenses, like my dad's old FD lenses. pic related was taken with a Tokina 200mm 3.5
For most of my video-work I use the 12-35mm 2.8, because it is parfocal and stabilized, but it costs twice as much as my body.
For allrounders, consider the 14-150mm 3.5-5.6 from Olympus or its Lumix counterpart.
If you want a bunch of good primes and don't mind switching, Olly and Panny both have a set of 1.7/1.8 primes around the 20mm, 25mm and 45mm mark, all are great and cheap, especially the 25mm 1.7 from Panny, because it costs like 170€. The mousehead was photographed with that one.
In-body stabilization Like Olly and the newer Lumix have makes adaptring lenses much better because you get an additional stop or two of light. Combined with a 1.4 lens for like 70 bucks on ebay, that makes your tiny camera a light-king
