A site that repeatedly takes my rumors without linking to me and edits their own to make it look like they are always first has called my Fujifilm X-T4 inference clickbait because he’s mad I beat him yet again. So here is some evidence to support my logical inference based on the previously posted rumor.
Fujifilm has previously stated that IBIS only works in the X-H1 line at this time because of the size of their IBIS system. They have also stated that they will bring IBIS to future cameras, like the X-T4, when they can reduce the size of their IBIS system. Most rumor sites post conjecture as fact and then edit their posts later, which we do not do here. I am always very upfront with drawing conclusions, but this is a very important one that deserves some elaboration.
Volume Calculations For X-H1, X-Pro2, X-T3
X-Pro2: 140.5 x 82.8 x 45.9mm = 533973.06 mm³
X-H1: 139.8 x 97.3 x 85.5mm = 1163017.17 mm³
X-T3: 132.5 x 92.8 x 58.8mm = 723004.8 mm³
The Fujifilm X-T3 currently has a volume of almost halfway between the X-H1 and X-Pro2, but more interestingly the X-Pro2 is less than half the volume of the Fujifilm X-H1. So if they manage to fit IBIS in the X-Pro3 than it most certainly will fit in the Fujifilm X-T4 or maybe X-T3s.
Now we can’t verify the X-Pro3’s IBIS at this time and the camera might be a little larger, but the X-Pro3 has an OVF that takes a significant amount of space inside the camera body away from electronics. Also, a lot of the weibo leaks have been spot on and it is actually where some sites have gotten their rumors for years instead of using real personal sources so it is probably accurate. These sites only started citing weibo when we started pointing out where the rumors are coming from.
If the rumor is true the only reason Fujifilm would leave IBIS out of the X-T4 would be to promote the Fujifilm X-H2. Thankfully Fujifilm isn’t known for withholding technology so I do not think they will do this, but the X-H2 might have significantly improved IBIS over the X-Pro3 and X-T4 if they all end up with IBIS in the near future.
