I already did a specs comparison between the GFX100S and Sony a1 here based on the info available at the time. Now Gordon Laing has released a hands-on comparison of the two cameras, which you can watch above or read the summary of below:
- 4th GFX camera
- Almost half the price of the GFX100 with essentially the same capabilities
- Fujifilm GFX 50S is discontinued
- The Full Frame Sony A1 actually costs more than the GFX100S
- The big bump from the GFX50S is gone
- Similar feels similar to a 5D or D800
- Changing the battery let Fujifilm to move the battery into the grip
- There is no portrait grip or dual batteries but it is smaller all around and 500g lighter
- New battery can do about 460 frames so battery life is good but you will want a second battery
- The EVF is now fixed and smaller than the GFX100, but it is still comparable to other cameras
- Sony has a more detailed viewfinder, but Fujifilm’s viewfinder doesn’t hold the camera back
- The main monitor hasn’t changed on the GFX
- PASM mode dial on the GFX100S which is different than other GFX cameras
- Can shoot for up to 60 min on the GFX100S
- 1.8″ eink display that’s like the one on the GFX100 and it can be reversed from white to black
- GFX100S misses the second einck display of the GFX100
- GFX100S should have larger controls that are backlit
- GFX cameras feel like X cameras in the menus
- UHS-II dual card slots that are fast enough for the 5fps of the GFX
- 12-bit RAW can be outputted via mini HDMI
- GFX lenses are great, but there are more lenses for full-frame bodies
- The 102MP sensor is the selling point of the GFX
- The IBIS is very useful
- Could shoot the 45mm f/2.8 with IBIS at 1/10th a second, but without he needs to shoot 1/80th
- IBIS is also good for video
- The AF is as fast as other cameras with smaller lenses
- The GFX feels like using a smaller format camera
- The standard test chart had to be shot at double the distance since the camera out resolved the test chart filling the frame
- GFX100S easily out resolves the Sony Alpha 1
- Both cameras do better with pixel shift and the Alpha 1 can out resolve a single shot of the GFX100S, but if you use multishot with the GFX100S you end up out resolving the Sony and chart again
- No camera under 10k out resolves the GFX100
- GFX100 can easily recover color data in the dark by lifting the shadows
- 4k recording is different on each camera due to how the cameras come up with their 4k from their sensors
- Motion tracking in video is fine for somewhat static subjects, but the motion isn’t tracked well in video
- GFX100S is Fujifilm’s most compelling camera to date
- The GFX100 and GFX100S perform like smaller sensor cameras, but the GFX100S is more portable
- The GFX100 can be shot casually thanks to its IBIS
- If you’re into fast sports and wildlife a camera like the Sony A1 might be better
- GFX only has 12 lenses at this time, but full-frame cameras have numerous choices
- GFX100S is best for photographers that demand the best quality and it speaks to your heart in a way other cameras do not
- There will be more videos comparing these cameras soon
