I’m another fan of Panasonic M 4/3, started with the GX1 and now have a GX80 and a GM1. For me it’s the ideal compromise between quality, size, weight and price. It also has the advantage of two manufacturers and lenses interchangeable between them.
The GX80 has more features than I’ll ever use and plenty I do - tilt screen, viewfinder, Wi-Fi, touch screen and plenty of physical controls. The GM1 is half the size and weight, the smallest M4/3 made, has the same sensor without a lot of the features.
More than ever the bodies are being seen as consumable, prices drop considerably a few months after release and off the cliff as soon as a new model is rumoured. But lenses are more of an investment and hold their prices. After swapping around a bit, I’ve settled on three nice lenses and another on the wish list, in future changing bodies will be no big deal, but changing systems would be expensive.
Not mentioned yet are the Sony systems, I know a couple of people who like theirs, larger sensor and therefore larger lenses, I almost went that way before going M 4/3.
A new camera will have to have a viewfinder as I hate shooting with an LCD as does Mrs Pcolbeck.
Try before you buy, I like the GX80 viewfinder but I know some don't, it isn't close to SLR.
