The cameras, left to right, Fujifilm X-E2s with Fujinon 23mm f/2, Olympus OM-D E-M5 with Sigma 19mm, Canon EOS 50D with Canon EF 24mm f/2.8 USM. Just for fun comparable prime lenses are shown here.
Here we try out the AE programming for Fujifilm compared to Olympus, plus a few Canon cases. In all cases the WB was Daylight, the ISO was Auto, and the meter mode was matrix.
For this first set the ISO for the Fuji is at 400 due to the DR setting being . That 200 is actually the floor ISO for DR, the AE may set the actual ISO higher.
For the Olympus E-M5 I tried two different aperture settings. The AE left the ISO at 200, compensated only with the shutter speed.
Note that for the set below the Olympus shots are at EV -0.5 stop. I don’t understand why, but the Oly metering seemed to key in more on the shadows than the other cameras. Thus this correction.
For the next set the lighting conditions were far from ideal. But that helps to see how the AE for these cameras deals with problem lighting.
Another scene with lighting conditions far from ideal. This time looking into the Auto and Landscape settings. Plus dynamic range options.
And now we come back to a scene that is not backlit. For Auto mode and scenes (which are JPG only) Fuji does not give the film simulation used. Fujifilm film simulation PRO Neg Std is the default for Fuji non-Auto modes such as Program mode.
Now for a subject that is entirely in the shade. At this light level WB for the Fuji is cooler than the Olympus. With both cameras Program mode gave a high shutter speed, so I also tried out their Shutter Priority modes as well.
This set will be modest low light, a fancy store display. The EXIF info for the first E-M5 image says Program mode, but it is actually iAuto mode.
We will finish up with a case of severe contrast, to see how the different Dynamic Range features are able to even out the brightness. The Auto mode for the X-E2s picked the Landscape scene. The Fuji’s Program mode resulted in different settings from that Landscape scene. The Olympus Auto mode did not match any of its scenes. The Oly tool for DR is their Gradient setting, which is similar to auto contrast. In this example it worked pretty well! The Fuji DR tool manipulates ISO, among other things. The DR on Auto was not as successful as the Oly Auto Gradient.
