Confucius say - don't do as I do - do as I tell you.
Actually what I said was that I wasn't going to rush out and buy an XT2 but wait for prices to drop. After a year I was still happy with the XT1 but someone made me an offer for it at a really good price and at almost the same time I was recommended to buy a refurb from a regretful GAS sufferer at a lot less than they paid Fuji. I finished up paying out £200 + XT1 for the XT2.
My advice for the 16-55 f2.8 (which still stands) was - if you are primarily a prime shooter (like me and which hints at being slightly anal about IQ) and only need zoom for such as vacations, you only need buy the 18-55mm XF or indeed the 16-50mm XC since it will be used only as occasional walkaround.
It was when I was commenting on the 18-55-16-55 debate on a Fuji forum that I would only buy one if it was cheap (unlikely since they don't come up for sale much) that a forum member tipped me off about one for sale at Park cameras. It was still available at a remarkable price and after a chat with my conscience, a promise (not kept) to sell my 18-55mm and without the benefit of your councel to stand up to GAS, I succumbed. The way I look at it you owe me £430!
I feel the 16-55mm f2.8 comes into its own on the 24MP sensor. On XT1 the difference with 18-55 is not obvious at any time and not really visible at f5.6 and smaller unless you're viewing at full size - except of course at 16mm or 55mm f2.8 where the gain in bokeh is definitely worth having. Whether it is worth enough to make carrying the extra size and weight is for the individual to decide. As it is, I prefer to use the XT2 and 16-55mm - maybe + 90mm f2 (both WR and Fujis 2 fastest focusing lenses). However, even this 1/2 lens outfit is sometimes too much for comfort these days and then i pick up my XT20 + 18-55 or if using primes then then again, the XT20 with 14, 23, 35, 60 (2 from 4). Having now reached my 70s and suffering from increasingly poor health I use the primes less. I walk with a stick which I leave go of to shoot but which is a nuisance if I need to swap primes and carrying more than 1 camera/lens means I would have a bag swinging around too, so you can see why the simple XT2/16-55 sans bag is close to ideal for me. I don't shoot much in wet weather now but If I am out in it, I don't want to have to take bags or covers and so on. I'm can carry the XT2 and 16-55 f2.8 as they are in average British rainfall perhaps putting it under my coat when needed. The thing is - the XT20+18-55 is half the size and weight of XT2+16-55.
I'd have the XE3 rather than previous generations or XT20 but not in exchange for XP2, XT2. I do think it was a miscalculation to not include tilt screen in XE3. I'm also annoyed that Fuji made the XE3 smaller in width when I'd always pushed the EX style over XT10/20 because the small extra width made the camera thinner, much more holdable and less squat/square and than XT10/20.
