FíRIN is a variation of Fírinne, the Old Irish word for "truth", which was coined during the Gaelic Revival in the late 19th Century. It means, "that which is real". It signifies "being true to someone or something". And it represents a promise from Tokina to photographers to help them capture the truth in their images with this revolutionary new lens.
With FíRIN, photographers can shoot with confidence, knowing that every image captured with their mirrorless cameras will be its own moment of truth.
"Firin 20mm f/2…more than a lens…having it as my adventures mate since a year. It survived to snow, -20° C, mud and extremely warm environment. If you want a trusted lens in each situation…just go for it! So sharp even at f/2, low distortion, metal built…outstanding lens!"
Alessandro Di Lago
