The Panny AF isn't half bad, DFD is not as quick as PDAF we're used to on SLRs, but in a compact like this it seems that the greater DOF comes to its assistance. I've had more joy in simpler, slower BIF with the FZ82 than I expected. It's light, and quite decent when viewed on phones - and these days, I get most pleasure out of sharing on phone screens [work, home, the family WhatsApp etc..].
Rambling thoughts.... It ain't ever printing A3, but at times I've wondered why I bother with fast wildlife primes when my main output these days is 'good enough' on a phone or iPad screen, and why I chase fast wide primes when my iPhone has a very decent computational portrait mode... what is our desired end result? Is it framed and purchased, or more likely a nodding approval from a jpeg on a small screen? If I'm honest, is it the process of taking photographs I enjoy more than the outright quality of the picture I get?
... if I were Nikon/Panny etc I'd be chasing the niches and working on computational algorithms to take away some of the phone business. I'd like to see AI augment an extra stop of bokeh out of lenses, I'd like to see a twist-zoom 300-3000mm 1/23rd sensor wildlife cam in a scope-type body, etc etc. Heresy alert: More than chasing the quality, makers need to also chase the usage. Samsung/Huawei/Apple are doing so well in photography because they focus on what the user wants more than what the kit can do - we want low light nightscapes, environmental portraits of the kids, ridiculous wildlife reach, and if it looks 'good enough' for 99% then 99% are buying the phone not the camera, and that's why camera businesses are hitting the obituaries. History is littered with good stuff from dead companies - Contax, Kodak, maybe Olympus [and I hope not], and no matter how well they are remembered, they risk becoming just that - memories.
