The number of lens elements is small, and the air surfaces are fully multi-coated, resulting in excellent light transmission!
We would like to introduce the 'Masuyama 26mm 85°' handled by Oi Koki. It features a 5-element, 3-group design without using a barlow lens. With fewer lens elements, it has a fully multi-coated air surface, providing excellent light transmission. It is particularly recommended for binocular users, with a barrel diameter of 58mm and equipped with a rubber eyepiece. 【Features】 ■ 5-element, 3-group design without using a barlow lens ■ Fewer lens elements ■ Particularly recommended for binocular users ■ Barrel diameter of 58mm, equipped with a rubber eyepiece *For more details, please refer to the related links or feel free to contact us.
