Image source did a video IBIS comparison of 4 popular crop sensor cameras the Fujifilm X-T4, Panasonic GH5, Olympus E-M1 III, and Sony a6600 at 24p and 60p. For this comparison, they used 35mm equivalent and 50mm equivalent lenses. All footage is 1080p using a rig designed for all 4 cameras so that they experience the same motion/vibration. Above is the video and below is the summary:
Test 1 Handheld Panning at 35mm 24fps
- All four handle it with relative ease (Sony looks like it is chugging a bit imo)
Test 2 Smooth Driving Vehicle at 50mm 24fps
- All cameras hand this situation well, but there are a few hiccups (Again the Sony looks the worst to me)
Test 3 Strolling Down The Road at 35mm 24fps
- Reasonably difficult test and GH5 does the best followed by E-M1 III (The GH5 almost looks like a gimbal is being used)
Test 4 Following a Bicycle From a Bicycle at 50mm 60fps
- Both 4/3 cameras and the X-T4 do a good job here on this simple test (a6600 is really bumpy here while the others are pretty smooth)
Test 5 Bumpy Golf Cart on a Smooth Road at 35mm 24fps
- Slightly tougher test GH5/a6600 are having problems while E-M1 III and X-T4 start smooth, but the last part of the test only the E-M1 III handles well, but the X-T4 does well in parts
Test 6 Bumpy Golf Cart on a Smooth Road II at 35mm 60fps
- Similar test at 60fps, which the GH5/E-M1III/X-T4 all handle well, but the X-T4 has some hiccups and the a6600 can’t handle the situation at all
Test 7 Bumpy Golf Cart on Bumpy Bridge 50mm 60fps
- Fairly difficult test for all of them with E-M1 III handling it the most smoothly and the X-T4/GH5 doing fairly well especially in the end
Test 8 Bumpy Golf Cart on Bumpy Bridge II 35mm 24fps
- The rig is on the golf cart now and all of the cameras have some level of difficulty with the bumps with the E-M1 III doing the best followed by the X-T4/GH5
Conclusion and Ranking
- Olympus E-M1 III – Handled all of the tests quite well and performed the best in most of them especially the toughest tests with a very fluid IBIS system
- Panasonic GH5 – Best for walking which gives it #2 because it is a common use case and it handles drives quite well
- Fujifilm X-T4 – Handles handheld panning and smooth driving scenes well, but isn’t quite as good for walking, but still handles it well
- Sony a6600 – Can handle easy panning and smooth driving, but it jumps around when conditions get bumpy
Image resource didn’t have the latest firmware on the Fujifilm X-T4 (1.02), which improves IBIS performance considerably, so it should do even better today. Personally I would say the X-T4 matched the GH5, but I agree that the Olympus E-M1 III did the best in every respect except for the walking test, in which the GH5 offers gimbal-like performance. I am really impressed with Fujifilm’s IBIS and how it has improved since the Fujifilm X-H1. I am also a bit shocked at how bad the IBIS is on the Sony a6600.
