The PENTAX smcp165mm f/4 LS (Leaf-Shutter) lens incorporates its own shutter mechanism which allows the use of a flash at speeds up to 1/500 second, making it an essential lens for shots requiring balanced fill-flash. Like all PENTAX lenses, this lens is treated with the acclaimed smc coating for maximum light transmission, sharp definition, and high contrast while minimizing flare and ghost imaging. |
