Landmark cameras: Panasonic Lumix G1

Panasonic has now made more Micro Four Thirds mirrorless camera models that we can count, but the one that started it all of was the Lumix DMC-G1 back in 2008.
We take mirrorless cameras for granted now, but this was a major technological leap back then, when DSLRs ruled the earth and digital electronic viewfinders had so far only been seen in the compact camera market.
