If adapted glass is your thing, or modern manual focus lenes (ie Voigtlander), then the ZF fits the bill very nicely. Yes it is heavy (and bigger) than the Fuji's but it is also built like a tank. It is more expensive than an X-T5 but grey import prices do even that out. The ZF is a very nice bit of kit.
Its horses for courses though, as the Fuji is smaller, lighter, and has an excellent range of native glass, and is now well supported by third party glass manufacturers.
We always want new things, some of us have more magpie tendencies than others
