> Depends on yer photog needs. But for hiking, I tend to bring only one small prime. Currently that means GX800 w/ 1.7/20mm, but always lookin’ for a deal on the 2.5/14mm.
I coincidentally have 20mm F/1.7! It feels a bit too bulky for carrying in a pocket with G85 (I realized I typo'ed that in OP). Still much smaller and lighter overall. I might give it another go... It was my main lens for a long time before it was replaced by 8-18mm, but it's really massive.
Good points regarding filters and other crap. I do have a wireless remote, CPL, multiple ND filters which I could get away without carrying. Lighter tripod is also possible with smaller lens.
> What you really need of yer kit
I will be completely honest and I do think that iPhone XS camera can be good enough for general shots. Unfortunately, it doesn't give the same satisfaction of taking photos and post-processing! Weird when you say it out loud.
I did have Fuji X100F for a brief moment until it broke. It was a joy to use, but I wouldn't get another one.
