I’ve already talked a lot about the advantages and disadvantages of the M4/3 system on this blog. To me the advantages clearly outweigh the disadvantages, but everyone has different needs and priorities. But here is an article in Outdoor Photographer by wildlife photographer Daniel J. Cox who has switched from Nikon to Panasonic M4/3 and is very happy with his move.
You can also watch this little video of his that shows how he fits 3 bodies, two super long telephoto lenses and a few other lenses and accessories in a mid-size rollaboard.
That’s what M4/3 is all about!
