What sets the X-T1 apart is its ability to deliver impressively clean, detailed images up through ISO 6400, a class-leading EVF, and a clever, very effective manual focus mode. You get access to a lineup of fantastic XF prime and zoom lenses. On top of all this is Fuji’s track record of improving camera features and functionality via ongoing firmware updates. So there’s a very good chance that your X-T1 will be an even more capable camera over your time of ownership.
This extract comes from a great article at Wirecutter.com on the subject of the world’s best mirrorless camera. Adamdou Diallo has two contenders, the Fuji XT-1 and the Olympus OM-D EM-1―a duo I would also rate as the ones to choose from. As a complete system camera, the both have their good points but Diallo comes down firmly in favour of the Fuji. Unless, that is, you already own a bagful of Micro Four Thirds lenses when the Olympus might tip the balance.
The Fuji’s bigger sensor wins it for me. Don Morley
