7Artisans 12mm f/2.8 Mark II 12mm
Its 12mm focal length (24mm equivalent) and f/2.8 aperture offer a compact 295g ultra-wide solution for Micro Four Thirds, with a de-clicked aperture ring enabling smooth, silent iris adjustments during video. The all-manual design includes depth-of-field and distance scales for precise zone focusing, and the 150mm minimum focus distance permits creative close-ups. This lens best suits landscape photographers and budget-conscious videographers on Micro Four Thirds who prioritize tactile manual control and a portable ultra-wide prime.
