To compare real-life RAW performance I shot this scene with the Fujifilm X-M1, the Olympus PEN E-P5, and the Panasonic Lumix GF6 within a few moments of each other using their RAW modes.

The X-M1 was fitted with the new Fujinon 16-50mm f3.5-5.6 OIS kit lens. To eliminate quality differences due to lens factors I used the Panasonic Lumix G Vario 14-42mm f3.5-5.6 II on both the PEN E-P5 and the Lumix GF6.

For the PEN E-P5 and Lumix GF6 the lens was set to its 14mm (28mm equivalent) wide angle setting. At its wide angle setting, the 16-50mm Fujinon lens has an equivalent focal length of 24mm and the X-M1 sensor has a 3:2 aspect ratio compared with 4:3 on the Micro four thirds models. I zoomed in marginally with the X-M1 to produce an equivalent vertical field of view.

All three cameras were set to Aperture Priority exposure mode with the senstivity set manually to the base ISO sensitivity setting.

The image above was taken with the Fujifilm X-M1. The X-M1 was mounted on a tripod and the stabilisation was turned off. Aperture priority mode was selected with the aperture set to f5.6 With the sensitivity set to 200 ISO the X-M1 metered an exposure of 1/900. Also at 200 ISO, the PEN E-P5 selected 1/1250 and, at its base 160 ISO setting, the Panasonic Lumix GF6 selected 1/1000 at f5.6

The cameras were left on their default settings for this test. The X-M1 RAW file measured 26.2Mb and, as usual, the crops are taken from the areas marked by the red rectangles.

I processed the files from the PEN E-P5 and Lumix GF6 in Adobe Camera RAW using identical settings: Sharpening at 70 / 0.5 / 36 / 10, Luminance and Colour Noise Reduction both set to zero, and the Process to 2012 with the Adobe Standard profile. To further reduce any distracting visual differences between the crops I also set custom white balance to 5500K. These settings were chosen to reveal the differences in sensor quality and isolate them from in-camera processing. The high degree of sharpening with a small radius enhances the finest details without causing undesirable artefacts, while the zero noise reduction unveils what's really going on behind the scenes

At the time of testing the Fujifilm X-M1 RAW format wasn't supported by Adobe Photoshop Camera RAW 8.1.0.43, so I processed the X-M1's RAF raw file in the supplied Raw File Converter application. I tried as far as possible to produce similar results to the Camera RAW processed files, setting sharpness to exagerrated, turning off all noise reduction, setting the white balance to 5500K and developing the result to a .tif file. While the resulting crops provide a useful idea of what the X-M1 RAW file can produce, it's not intended for comparison with the Camera RAW processed files, so I'll confine my comments to the X-M1 RAW files compared with the JPEGs on the previous page. I'll update the X-M1 crops when Camera RAW support is becomes available in Adobe Photoshop Camera RAW..

So what about the crops? As I suspected these processed RAW files from the Fujifilm X-M1 show a greater level of detail the in-camera JPEGS. At this high level of sharpening and in the absence of noise processing they also look very grainy but, despite that, you can see a lot of the finer detail in the stonework, roof tiles and brickwork than was visible in the JPEGs. So at the very least, these files confirm that with a little effort there's every chance of squezzing even better results from the X-M1 RAW files.

You can see how these models compare at higher sensitivities in my Fujifilm XM1 Noise results.
