Good deals now to be had on the Lumix G5, now that rumors persist of a soon-to-be-released G6. The image quality of the G5 is just a half step below the top of the line GH3 and its Olympus counterpart.
A great lens selection in the micro-4/3 lineup, and the G5 sports the fully silent electronic shutter option that's only found elsewhere in the format with the GH3. My experience shooting on the street with the G5 set to e-shutter mode, and with all other sounds turned off, is that it's absolutely dead quiet and blazingly fast, the next best thing to a cell phone camera for street shooting, in terms of stealth.
I think the built-in hand grip and EVF are great features, too, along with the swiveling LCD screen. And a built-in flash, for when you need it.
Did I mention lenses? Both Oly and Panasonic make some great lenses, with Panasonic's new constant f/2.8 pro zoom lenses being an example of how they are constantly improving the format.
Heck, even the Olympus BCL-15 body cap lens (fixed f/8 aperture, manual focus, hyper focal detent, 15mm focal length - 30mm equiv. FOV) is great for daytime street photography.
Yea, sorry. I'm sold on micro-4/3, hence the enthusiasm. I think the format hits the sweet spot between portability, flexibility and performance, at a decent price.
