Here’s my tuppence-worth….
In early January I traded in my 2016 X-Pro2 for the X-Pro3, and have been using it almost every day.
As a healthy sceptic about the ‘3’ when it was released, I had loan of one for day to appraise myself, and really enjoyed using it. So what sold me the camera?
A number of things:
As a wearer of varifocals, the EVF is easier to see than the ‘2’ (I rarely use the OVF so I’m not bothered by the loss of the dual magnification - but yes, I agree, a bad decision on Fuji’s part).
The AF is much faster.
The AF is usable at lower light levels.
The ‘3’ is more responsive than the ‘2’.
The viewfinder diopter adjustment is harder to move (the bane of my life on the ‘2’, I resorted to taping over it, mostly unsuccessfully).
The divisive, hidden LCD is neither here-nor-there with me as I rarely chimp, but I do like the fact that the screen is protected when closed, and unfolded I have the option of taking shots with touch focus. Also it is easier with the screen unfolded to 90 degrees to view a day’s shooting with the camera on a table.
Not a real biggie but battery life is better by about an hour in a day.
Downsides/criticisms?
Major one with me is the lack of an included battery charger. Done for penny-pinching, it means unless I shell out £45 for a separate charger, I can’t charge a battery and use the camera at the same time - and Fuji should supply a longer USB/C cable.
Titanium top and bottom covers. A gimmick in my opinion, making the camera more expensive - but there is a cheaper black paint version - still titanium though, I understand.
The charger port cover is pathetic, it should be hinged and lockable. I can see this being a weak link as it gets a lot of use.
So, I guess some are wondering why I didn’t just go with the X-T3? Simple: I don’t like centre viewfinders as found on SLRs, I love the viewfinder on the lefthand rear edge. For me, the weather-protected X-Pro3 just handles better and suits my needs better.
