I agree the evf on the GX80 is junk but only better than not having one at all.
Yup it's better than not having one at all and even 5 years ago it probably would have been cutting edge but these days it's poor. I actually preferred the EVF on my first generation G1 for use in good light although it was unusable in low light.
I'm quite stunned that Panasonic have persisted with this type of EVF although to be fair I obviously haven't tried the GX9... so maybe it'll all be ok but I do have to say the EVF's on my GX7 and GX80 are poor. Every time I use these cameras I'm disappointed and annoyed by the crap EVF, it spoils the experience and does annoy me every single time I use them.
I suppose another thing to consider is me / us lot whinging on forums are a tiny percentage of the market and although I'd rather have my nails pulled out than buy another serious camera with a field sequential EVF like the ones I have I suppose thousands of people will buy these cameras and never complain.
I've been toying with the idea of giving up and buying a Sony APS-C but lenses are a problem.
These are my lenses...
Oly 17mm, there's no compact 24mm f1.8 Sony lens. The one they have is apparently very good but IMO too big and it's expensive.
Oly 25mm and Oly 45mm, there are Sony lenses that could replace these easily enough.
Oly 9-18mm, there's a Sony wide but it's quite big and expensive.
Panny 14-42mm kit lens, easy to replace.
Panny 12-35mm f2.8, there's no Sony option. There's a f4 zoom but it's quite big and expensive.
Panny 45-150mm, the Sony equivalent is big.
So, for the Oly 17mm and 9-18 and the Panny 12-35mm and 45-150mm lenses there's no easy replacement as the Sony's are bigger and more expensive, so I'm stuck with MFT liking the lenses but not exactly a happy bunny over the cameras.
