>>4465101I went from the a6300 to the A7CII, I had the same questions as you, and pondered whether or not I should jump on the FF meme as I want my camera and lenses to be compact (mountain hiking, travels).
The gain in noise and dynamic range alone made it so I don't bother with bigass fast FF lenses. And the lenses offering is fucking big in FF, thanks to all the third parties. Viltrox and Meike have good offering for cheap, on top of the usual guard like Sigma, Samyang, Tamron. Upon using them, I found smoll f2.8 FF lenses werk actually better than the equivalent in APS-C, nor are they that bigger or weight more. Though it's true I tend to use primes, not zooms. If you want a zoom, FF ones will be bigger, they tend to aim for f2.8, if not f2.0 these days. I'd kill for more F4 zooms, though the 20-70 is very tempting. An update of the old 24-105 f4 zoom would be perfect for travel. So far I kept my old Sony 18-105 Z f4 APS-C zoom if I really need one, but 3 primes cover all my needs when traveling. I'm looking at the upcoming Sigma 20-200 and the surprisingly good Tamron 28-200 for my hiking needs.
Your gripes with the A7CII already exist in your current a6700, you might want to wait for the A7cIII, but expect it to be pricey and not come out until late 2026 at best. Personally I don't have any problem with the EVF. I wish the screen was higher res but it's not unusable, I don't use it much anyway. What I miss though is the flip screen I had in my a6300. I like some of the possibilities offered by an articulated screen, but I prefer the flip form factor so I can do comfy waist-level photography just by flipping the screen in 0.5s. If they make an A7cIII witht he same full articulated+flipping screen of the A7RV, I'll probably buy it next time I travel to Japan.
