As a former owner of this body, the Canon 550D (and historically all Rebels) definitely overexposes about half a stop. Had to compensate down almost always. In comparison the Fuji X-E1 trumps it in default exposure and white balance.

+1. I'm glad someone else finally got to the root problem. I had to shoot everything on my T1i at a -1/3 EV. The Rebel line was notorious for over exposing. On a shot for shot basis my T1i doesn't even match my 7D w/o dialing in some negative exposure compensation.

This thread is not about (in)accurate metering at all, but about the image result in a manual exposure situation. Both cameras used the same manually set exposure parameters (aperture, time, ISO). The Fuji image is darker.


No where in my post did I ever state whether my exposures were made in an auto or manual mode when comparing a 500D to a 7D to my X100. I've shot plenty of manual in the 30+ years I've been shooting and understand how to underexpose (or overexpose) by 1/3 stop even shooting in manual mode by either adjusting aperture, shutter speed or ISO.

That being said, there is nothing wrong with the sensor or the metering in the Fuji. Fuji's metering and exposures are close to spot on usually. The issue with the OP's images is a fault of the system in the 550D. This camera line notoriously overexposes by 1/3 to 1/2 stop in any mode. Even with the same settings under the same lighting the Canon images will look overexposed because they are overexposed. If shooting in an auto mode it is corrected by dialing -1/3 EV and if shooting in manual I would compensate by opening up 1/3 stop on the aperture or adjusting the shutter speed or ISO as required.

To the OP, try shooting the same scene. Then make an additional exposure on the 550D underexposing by 1/3 to 1/2 stop. You will find they more than likely will match your XE-1 exposures.

This is exactly what I wrote: With the same scene, and both cameras set to the same exposure settings (same aperture, time, ISO), the Fuji image will be darker than the Canon one. The Fuji sensor is less sensitive than claimed (compared to most other cameras). Which answers the OP's question, why the Fuji shot is darker.

Your claim that "the Canon 550D (and historically all Rebels) definitely overexposes about half a stop" is a potentil Canon metering issue but related to the OP's question, not at at it's "root problem". And my "manual mode" comment was not refering to your metering tests, but to the OP test situation who explicitly mentioned "results takes with 2 cameras under same settings, both 18mm, f4, 1/30, iso400, Auto WB".
