Quite a few questions about software support have come up for various mirrorless cameras, so I'm going to try to track some of the mainstream programs. Here is the current (see date at bottom of article) support:
- Adobe Lightroom and Adobe Converter Raw (Photoshop/Bridge) — supports Canon EOS M, Fujifilm X-Pro1 and X-E1, Leica M8/M9/M Monochom/M-E, Nikon 1 (all models), Olympus all m4/3, Panasonic all m4/3, Pentax K-01/Q/Q10, Ricoh GXR (all modules), Samsung NX (all models), and Sony NEX. The Fujifilm X-trans support was recently updated, reducing the color smear problem but also reducing detail/acuity; I'm not sure that was a good trade off.
- Apple Mac OS-X — The Digital Camera RAW Compatibility module (current version 4.06) that Apple maintains provides both support at the OS level, but for a number of applications, as well, including Apple's own iPhoto and Aperture programs. Currently supports Canon EOS M, Fujifilm X (all models), Leica M8/M9 (but not Monochrom, M-E, or M 240), Nikon 1 (all models), Olympus all m4/3, Panasonic all m4/3, Pentax Q (but not K-01 or Q10), Ricoh GXR A12 and X10 modules, Samsung NX (but not NX20, NX210, NX300, or NX1000), and Sony NEX (all models).
- CaptureOne — supports Canon EOS M, Fujifilm X-Pro1 and X-E1, Leica all models, Nikon 1 (but not V2, J3, or S1), Olympus all m4/3, Panasonic all m4/3, Pentax Q (but not K-01 or Q10), Ricoh GXR (all modules), Samsung NX (but not NX300), and Sony NEX. Like Adobe, CaptureOne has just updated their Fujifilm X-Trans support, but seems to have gone a different way than Adobe: more detail at the expense of some modest smear.
- DxO Optics Pro — has specific camera/lens combinations that it supports. Currently supported cameras include the Canon EOS M (with both EF-M lenses), the Leica M9/M9P/M-E with six Leica lenses, the Nikon 1 series with all but the latest lenses (new 10-100mm, 6.7-13mm), the Olympus m4/3 cameras with almost all the Olympus/Panasonic lenses, the Panasonic m4/3 cameras with almost all the Olympus/Panasonic lenses, the Pentax K-01 with a large array of lenses, and the Sony NEX cameras with all the Sony E-Mount lenses and a small number of third party lenses. The Fujifilm X-Pro1 and X-E1 are not supported, nor are the Samsung NX models.
