What I was trying to illustrate is that I know from the spec sheets alone that it doesn't fulfil a need that I have. Can it produce nice photos? Sure, but so can my iPhone. Can it mount all the LTM lenses I've got lying around? Sure, but so can my X-Pro 2. Does it give them the "correct" field of view - in other words, can I use them the same way I use them on a IIIg? No. That annoys me enough on the X-Pro; I'm not spending £2.5k on another camera with the same "problem" when a Leica M is only an extra couple of hundred quid more. I don't know why it's so hard to comprehend that this is a real deal breaker for a lot of people, and that I don't need to use a Pixii to know that it's an issue for me; I don't need to ride a Vespa to know that it isn't the same as a Ducati. I'm not saying either is worse - there are a lot of people who love Vespas - but it actively isn't for me.
The X-Pro 2 also has an (optional) electronic shutter, just like the Pixii's. It's weird using something so silent with no physical feedback, and in 99% of cases, it does work fine, you're right. But every so often, it does throw up weirdness. I shoot a lot of high-speed sport photography; a camera that doesn't have a mechanical shutter would be utterly useless to me. Again: Vespas and Ducatis.
I didn't think the Pixii had an SD card slot? If it does, I'm wrong, and I take it back. But SD cards are incredibly useful things - I shoot a lot of video (another thing the Pixii can't do, correct?), and it's easy to fill up a 32GB card or internal storage, especially in shooting 4K. SD cards are small and easy to swap out. But even when I'm just doing product photography, it's much, much faster to take an SD card out of a camera and slot it into a laptop and access directly than it is to faff around with cables or proprietary software.
There's also the issue of redundancy: a professional sports photographer I know well refused to drop his Nikon DSLRs in favour of a mirrorless system for a long time because of the lack of two SD card slots in early mirrorless bodies. He sets his camera up to save everything to both cards at once (I don't know whether it's RAW on both, or a RAW/JPG split) so that if one card fails, he's got a backup. You can't do that with a Pixii. Or a Vespa, I guess.
Anyway, Boojum... if you like pootling around on your Vespa, that's great. More power to you, and it looks lovely - but it isn't for everyone, and you really don't have to defend them and spread pro-Vespa propaganda at every turn!
