Optically identical to the 150 mm f/3.5 Mamiya camera lens, this model boasts a few additional features that may appeal to some photographers. This Mamiya A N/L LS lens has an internal leaf shutter which enables flash synchronization for up to 1/500 of a second, when using the outdoor fill-flash. The leaf shutter on this 150 mm f/3.8 lens slightly reduces the maximum aperture in order to do this. As a manually operated lens, the Mamiya A N/L LS lens is a compact telephoto lens, working as an all purpose lens which many photo enthusiasts find a great accompaniment to their lens collection. This 150 mm f/3.8 lens is ideal for taking portraits, sports shots and landscape photography, though there are certainly more applications than just these. The Mamiya camera lens has a minimum shooting distance of 150 cm, so it is not ideal for close up shots. Finally, a fast shutter speed makes this Mamiya A N/L LS lens an option for capturing that fleeting moment in time.
