Many photographic commentators believed that the Micro Four Thirds small sensor digital camera format was dead and buried, especially after the Olympus brand was hived off to OM Systems, and Panasonic began producing full frame cameras. Lately though, the Micro Four Thirds system has had something of a renaissance, with Panasonic introducing the G9 mark ii, and OM Systems producing a new camera model the OM-3, together with some new lenses. OM Systems are continuing to develop, and innovate, contrary to industry speculation. My reasons for selling my Fuji X-T3, and buying back into the Micro Four Thirds system, with an OM System OM-1, are threefold; I want to create more landscape photos, macro photos, and some bird photography (not to Harry Kerman’s level but just some passable images). For bird photography I needed a lens with a longer focal length, and for a camera with an APS-C, or full frame sensor, the lenses get heavier, and more expensive. With the Micro Four Thirds OM-1, I have bought a 75-300mm Olympus lens which equates to 150-600mm on a full frame camera, giving the reach that I needed. For landscape photography the OM-1 has in-camera ND filters, and for macro photography the camera has in-camera focus stacking which should come in useful. The advantages of a Micro Four Thirds system are well documented, lighter compact lenses, with greater depth of field for macro, and wildlife photography. The professional Olympus / OM System cameras are rated IP53 weatherproofed, as are all the “Pro” range of lenses. There are also a dizzying range of lenses from Olympus / OM Systems, and Panasonic. Choosing my prime lenses for the camera has been relatively straightforward, the Olympus 17mm f/1.8 (34mm full frame equivalent) was a must have, having previously owned this lens, and taken some amazing images with it. The Olympus 45mm f/1.8 was another simple choice for portraiture. However, the Olympus 25mm f/1.8 (50mm full frame equivalent) lens has been a strange choice for me, as I usually prefer a wider focal length of around 40mm full frame, but the detail rendering, and micro contrast of this lens has really surprised me. Choosing a standard focal length “Pro” lens has been much more difficult, I’ve agonised over the Olympus 12-40mm f/2.8 “Pro” constant aperture lens, or the Olympus 12-45mm f/4 “Pro” constant aperture lens, finally deciding on the Olympus 12-45mm f/4 as it is smaller, and lighter, and the brighter apertures are provided by the prime lenses. Owning the camera has been a steep learning curve, there is much to learn, and many buttons, and controls to configure. My post processing workflow has completely changed, the Olympus RAW files contain the Adobe DNG / DCP information, which was not available with Fuji RAW, so I always shot with JPEG on Fuji. Now, I always shoot RAW with the OM-1, the .ORF RAW images download to my laptop at around 20 megapixel, and the files are readily, and quickly processed in Luminar Neo by choosing from the DCP camera profile list. The resulting post processed images look very natural, and organic.
