Positives:
– Bokeh is absolutely stunning. The f/2.8 aperture allows for beautiful background blur, making your subject really pop.
– Build quality is superb. The lens feels solid and durable, not too heavy but not too light either.
– Sharpness is remarkable, even when shooting wide open at f/2.8. Images are crisp and detailed.
– Focus ring is smooth and easy to operate. It’s a pleasure to manually focus with this lens.

Negatives:
– The lens is not very versatile due to its fixed focal length. It’s great for portraits or close-up shots, but not ideal for landscapes or wider shots.
– It can be difficult to find a compatible camera body, as Mamiya is not a commonly used brand anymore.
