I've just sold my FZ1000 II. The view finder was excellent, but found I wasn't taking it enough to places as it's too big. I don't mind big if I'm going to an airshow or a zoo, but I don't always want it that big and heavy.
I want to return to M43 after trying a Sony A6000, but not really getting on with the handling or EVF. I've previously owned lots of M43 cameras - GX800, GX85, GX7, GX9, OM-D EM10 II, PEN E-PL9. I haven't been convinced by the view finder on any of those, to the point that I never used to use it.
Is the G85 as good a viewfinder as the FZ1000? I know it's still a big heavy camera. Has the viewfinder improved on the EM10 III or IV over the II?
Are the EM5 II, III, or even GX8 or original EM1 I worth looking at?
Disdain -
You say that you want to get a new camera PRIMARILY because your FZ1000ii is too "big and heavy". That camera (with a 24-400 mm lens and a 1 inch sensor) weights 28.5 ounces (808g). One of the smaller m4/3 recommended was the Oly E-M5iii. It weighs 15.9 ounces (450g) WITHOUT the lens. If you attach a Oly 12-200mm F3.5-6.3 lens that ADDS an additional 16 ounces (455g). The total weight of this combo is slightly more than the FZ1000ii which you feel is "too heavy". Also, at the max equiv. zoom (400mm) the FZ1000ii has a much faster lens (but a slightly smaller sensor.
You don't mention what type of photography requires the smaller weight/size. For me personally, the smallest, lightest, and most versatile pocketable camera is the Sony Cyber-shot DSC-RX100 VII which has a 1 inch sensor and a 24-200 zoom at f/2.8-4.5. It takes great shots and I often carry it along with my Oly/Panasonic cameras/lenses. Actually, the price of a new E-M5iii + a reasonable llens may cost more than a new RX100VII
Don't get me wrong ... I think m4/3 offers many great smaller/lighter options and that, in large part, is why I mostly use m4/3 system for my photography. But having a great pocket camera like the Sony RX100 is a very useful and easy to carry companion for my m4/3 equipment.
Just my two cents (0.019 Euros) ...
