My wish list for the X-T2 looks like this
1) a battery meter that actually meters the battery. I've taken my camera out when it says it has a full battery and had it die before i was finished framing a single shot. If the battery is halfway to dead or even on the verge of dying, i would appreciate the meter saying as much. How the hell has this not been fixed yet.
2) higher resolution sensor - I make prints and I would like them to be sharper, these lenses kick ass and my printer is using every pixel on anything larger than 8". I don't care if it's X-trans or not. It would probably be better if it had more than 15 phase-detect points.
3)push-push locks on the dials. As useful as dial locks sometimes are, I'd love to be able to unlock them and have them stay unlocked. I keep accidentally changing the drive mode while contorting my hand to change the iso on the go.
4) Built-in GPS. The phone app is a janky disaster, a gps antenna uses almost no power and geotags are very useful to me.
5) RGB histogram, and the option for zebras in the viewfinder
6) A RAW shooting mode, or at the very least the ability to save raw files when you bump the drive mode from S to double exposure or whatever (i hate that S is dead centre on the dial next to that minefield). It'd be nice to see a preview and histogram based on the raw files, but I'll at least take not being stuck with jpgs after. If i really had my druthers, raw mode would hide the millions of options cluttering the menu that only effect jpg files.
7) either drastically improved or completely untouched video. But since they're probably working with a new sensor and don't have the option to do nothing, they might as well go all out and nail it the first time: 4k, all-i, super high bitrate, all the pro video bells and whistles i don't fully understand. The same consumer-level video, followed by a kaizen update with marginally better consumer-level seems like a massive waste of their development time. Panasonic's success here kinda proves that video is mostly a software problem and all you have to do to get a huge fanbase is offer good enough video.
8) ETTR metering. We have the exact output from the sensor and a fulltime histogram!!! If I'm shooting in A-mode in the early evening with the sun outside the frame there is no reason to have blown highlights!! I know this is a lot to ask, but we're 20 years into the digital revolution, i would like my camera to work in a way that understands it's own medium. Having to shoot even my casual snapshots in full manual specifically because my camera is not programmed for a digital sensor is ridiculous.
9) everything else pretty much exactly the same, these are almost the only things i don't like about my x-t1
My Lens wish list looks like this
1) A WR 10-24/2.8 that's as uncompromising as the other two red-label 2.8 zooms are. The 10-24/4 is probably my least favorite Fuji lens. It's an awesome lens overall, especially compared to other uwa zooms but its slow, a little soft and not weathersealed.
2) knowing they won't make that, a ~10 or 11mm F/2. It would bookend the current lineup of primes and give both night landscape and concert shooters a new favourite lens. If it had straight aperture blades that would be icing on the cake.
3) 16-90 F/4 WR. As solid as the 18-135 is, it's not a constant aperture and its not wide enough. Going all the way to 90 would be a nice way to oneup canon and nikon's F/4 zooms.
4) A bigger 35mm, faster or better corrected, whatever, i just want a lens i can use comfortably without taking the grip off my xt1. This is admittedly a kinda stupid thing to complain about. An x100 with a fixed 35 is probably more sensible.
5) some cheap slow ish, decent-performing primes so that i don't have to tell people interested in the system that nearly every interesting lens is exactly $1000. Maybe sigma could release some more of those DN lenses, they're spectacularly alright for the money.
I switched to Fuji in the first place because their philosophy gelled with mine, so i don't think most of this is too outlandish.
