The wide F/1.8 aperture is a key feature of this lens, allowing significant light gathering and shallow depth of field. This is particularly beneficial for:

• Astrofotografia: Capture faint stars and the Milky Way with shorter exposure times, minimizing star trails.
• Fotografia amb poca llum: Shoot in dimly lit environments without excessively high ISO settings.
• Creative Wide-Angle Shots: Achieve a distinct separation between your subject and a blurred background, even with a wide-angle perspective.
