If it matters enough to you to do such testing, an EF-FX adapter will allow you to use Canon lenses on the FujiFilm body. You'll have to focus manually and use a hack to set the aperture. STM lenses and some USM lenses won't be able to focus. You could also use manual lenses with adapters for both EF and FX mounts. Options include Nikon F, Pentax K, and M42.ĭifferences in lighting. You took the test shot after noticing the ISO difference between the cameras. It's unlikely that lighting just happened to decrease every time you used the FujiFilm camera, but not the Canon camera.Īuto Lighting Optimizer (ALO). ALO works by reducing image contrast. A similar effect can be achieved on a FujiFilm X-Series camera by adjusting highlights and shadows settings. Your Canon test image does not look like an ALO-adjusted image. It does look like exposure was increased. I don't have the Canon body anymore, so cannot test using the brighter lens on Canon vs the darker one on FujiFilm. But I'd expect a 1.3-stop difference. To determine the specific contributions of various factors to the results you're seeing, you'll have to further test your equipment.
Lenses can transmit different amounts of light, despite using the same aperture setting. Here are two images taken with different lenses using the same camera body and settings. Again, there is about a 2/3-stop difference. Here are some test images taken on Canon and FujiFilm bodies with the same lens and exposure settings. I estimate about a 2/3-stop difference. Squealing issue is completely gone and the behavior of my lens is back to normal! I've had confirmation from a couple of other people that this works for them too.Īll the usual caveats apply here of course, YMMV, use at your own risk, void your warranty etc.The difference you are seeing is likely caused by a combination of effects from using different bodies and lenses. To compare lenses, use the same camera body. To compare camera bodies, use the same lens.Ĭanon and FujiFilm cameras do produce images with slightly different exposures at the same settings. According to the Wikipedia article on Film Speed, camera manufacturers can choose from "five different techniques for determining the exposure index rating at each sensitivity setting". FujiFilm is reported to use the SOS method. Canon apparently uses the REI method.

I loaded my patched "3.23 in 3.24 clothing" version onto the SD card, the update ran successfully and upon restarting and doing the firmware check the lens now says version 3.23 (as the actual firmware version number is contained in the code, the header is simply to tell the installer which version it's looking at before installing) MD5 checksum for the patched firmware: 9f79d44b34c6910a035a9e547edbea3e

You can quickly check the integrity of the patched firmware file by dragging and dropping it here to make sure the patch was applied correctly:
No other changes to the firmware file occurred) (I confirmed afterwards with a hex editor that the only change between the original 3.23 and the patched "3.24" version was a single byte near the beginning of the file (23 became 24). Go back to the top and click "Download patched firmware" Make sure the only option selected is "Increment version by 1"Ĭlick "Compile patched firmware" button down the bottom I used the brilliant FujiHack firmware patcher to increment the version number by 1 so that the 3.23 firmware would appear to the camera as 3.24, and thus allow it to re-install over the faulty 3.24 firmware.Ĭlick "Choose file" and select the 3.23 firmware downloaded from the Wayback Machine So the above 3.23 version above is useless as the camera will refuse to downgrade to a lower version.

If it's the same or higher than the current lens version it will install, if it's lower it won't install it. When the camera loads the firmware from the SD card, it looks at the file header for the version number. I had looked at a few posts about the firmware before updating but somehow missed all of the posts regarding the issues people were having! It doesn't seem to be super widespread but I've personally seen posts from at least 20 people affected by this issue.īy sheer luck, a single copy of the previous 3.23 firmware was archived on the Wayback Machine so I could compare it to the current 3.24 firmware I had downloaded and installed.
I updated my XF 18-55 (made in Japan) a few days ago and it started doing the horrible squealy noise when zoomed between 35-55mm.
