It's no secret that the Fujifilm X100VI is nearly impossible to buy right now, with Fujifilm citing months of catchup ahead to fulfil orders again. If you're looking for solid performance in a charming package, here are five solid X100VI alternatives that deliver the goods. https://www.notebookcheck.net/5-Fujifilm-X100VI-alternatives-you-can-actually-buy-without-the-3-000-scalper-markup.816038.0.html
Dear friend, if you summarize in so brillant way the road to light, friendly and sexy small cameras, I have to tap your shoulder and ask: why don't you suggest to your faithfull followers a delicious camera like Panasonic LX100II ??? Best wishes.

The actual alternative, and the only legit one, is a Sony RX1R II.
Just like the X100VI, it has a splendid 35mm lens built in (even a better one than the X100VI), a 42 MP sensor, a top left finder, is fairly compact, it just lacks the image stabilizer and battery life, but it's also full frame and therefore comes with native F2. Comes at about 1.5k used and is on par in most regards.
That is he only alternative here without going into compromising.
Mind if I suggest the Lumix GX9? It's quite the powerhouse for its size.
