The 7Artisans FF 10mm F2.8 Sony E Mark II is a manual fisheye lens for full-frame cameras that offers a dramatic perspective and creative spatial representations with an extremely wide angle of view of 185 degrees. The optical construction consists of 11 lenses in eight groups, including one aspherical lens and two ultra-low dispersion elements, which effectively reduce chromatic aberration while maintaining image sharpness. The bright maximum aperture of F2.8 ensures reliable performance in various lighting conditions and contributes to the compact, lightweight design of the lens. Manual focusing allows for working with subjects as close as 15 cm, enabling intimate shots while capturing expansive landscapes. The click-stopped aperture ring provides smooth, quiet exposure adjustments for photography and video applications. This successor to the Mark I features improved sharpness in the mid-image areas, optimized performance against color fringing, and a redesigned housing with fluorescent scale markings for better visibility in low light. The robust metal construction ensures durability, while the black finish maintains a professional appearance. Compatible with Sony E-mount full-frame cameras, this lens is ideal for travel photography, landscape shots, panoramas, night photography, underwater photography, and creative visual projects that require special perspective effects.
