The Micro 4/3 (MFT) system as with Panasonic Lumix G interchangeable lens series, and Olympus E-P, E-PL series of mirror-less digital cameras are becoming ever more popular, yet third party lenses are very thin on the ground.\n\nSamyang developed a specialist fish eye lens for these Micro four-thirds system, namely Samyang 7.5 mm f/3.5 UMC Fish-eye MFT. Samyang 7.5mm Fisheye offers exceptional optical performance. It is a “full frame” diagonal fisheye lens for Micro 4/3rd sensor cameras, meaning that the image it produces fills the frame on MFT cameras. Offering an exceptionally wide angle of view, up to 180 degrees diagonally, the 7.5mm gives a unique fish-eye perspective and makes it a very useful lens for making panoramic photographs and virtual tours with 3rd party hardware and software.\n\nSamyang 7.5mm fisheye lens is extremely compact, yet this new Samyang successfully combines the best features of highest quality optics and stylish construction, available in black and silver finishes.\n\nThe lens construction is 9 elements arranged in 7 groups, 6 bladed aperture, Dimensions: 48.3mm x 60mm, and lightweight at only 197g. The fixed, built in lens hood helps to alleviate flare from behind the lens.\n\nAs with all current Samyang lenses it features manual focus, but with such a large depth of field focus can be roughly set with to distance scale on the lens, or for very critical operations can be focused with zooming in to live-view which all MFT cameras offer.\n\nThere are no electronics to go wrong with this Samyang 7.5 mm, so when using on some models of camera, including the Panasonic Lumix G series “Shoot W/O Lens” (Shoot without the lens) needs to be set to ON in the cameras menu to allow shooting with this lens.\n\nThe Samyang 7.5mm f/3.5 UMC Fisheye MFT lens offers excellent optical performance even disregarding its class and price point, and should be seriously considered for all Micro Four Thirds users wanting a special ultra wide angle fisheye lens for photography or film applications.
