thanks Renaissance Man!
 I only need one pancake so I can keep camera with me at all times (the 20mm 1.7 will do perfectly). Will be investing in quality glass afterwards regardless of size, for specific uses (right now I have a Zuiko 50mm 1.4 which I will be adapting).
 I found this good (imo) example of graded gx7 footage https://vimeo.com/100958195 and it's convincing for my needs. thanks for the links to that shootout, going to check that out!

Still not jacket pocketable. 
Despite the bitrate, the quality in video mode is neck and neck--the GH3's bitrate advantage is offset by the GX7's better sensor. At least in my experience. 

Are you looking for the most compact lenses, or the best? IMO, SLR Magic makes the best Mu43 lenses, but they're manual focus only. If you want AF, it's between the Olympuses and the Panasonic Leicas, depending which look you prefer. 

Here's some food for thought. You needn't take Shane's words as gospel (the Olympuses look great wide open to me, if a bit sterile--more of a corporate/broadcast documentary look), but it's a good place to start finding what look you like.

In my experience, they're close enough as makes no difference. The GX7 has slightly better DR and cleaner shadows, but only has 12-bit RAW files compared to the Canon's 14-bit, which makes the ends of the tonal scale a little more "brittle" when processing. With the quality of Mu4/3 glass, I'd give the GX7 the edge, but at that point you're picking nits. 

In video, on the other hand, the GX7 absolutely stomps the Canon. 

GX7. Same or slightly better quality as the GH3, but smaller and better in low light. The only downside is no headphone or mic jack. You can grab it for $300 used if you hawk forums for used copies.

GM5.

Also consider the GX7 or LX100.

i had a nex 7 which is a little bigger than the a6000 and i fit it in my jacket pocket with the 20mm f2.8

A used GH3. I'm sure you can get one for € 500,00 or less.
Video is much, much better than a 550D!

Check out one of my latest shoots with the GH3. I'm still impressed with what it can do and it is already 3 years old technology.

Used g6.
