二手 Mamiya 150mm F4 Sekor-C 鏡頭（適用 645）

Picked this up for portraits and the glass is surprisingly clean for a used piece—no haze or scratches I can see. Focus ring moves smoothly, which is exactly what I was hoping for with a used lens.

The aperture ring clicks into each stop with a satisfying, precise feel that reminds me of older, well-built glass. Paired with my 645 body, the 150mm focal length creates lovely separation for portraits without being too tight.

Focus is tack sharp on portraits even wide open, which is exactly what I needed for my 645 kit. The metal barrel feels solid and well-used in the best way.
