High-quality macro lens using simple drip-proof construction

This lens enables 1:1 (1X) photography at distances up to 13cm from the lens to the subject. The refined aluminum alloy body has a simple drip-proof construction and is built with a compact, lightweight design without an iris ring. This reduces ghosting and flare for enabling superior imaging performance for sharp images with high contrast at all shooting distances. A round iris diaphragm is used for rendering natural out-of-focus (bokeh) background effect.

Features / Specifications

Refined design using aluminum outer casing and comfortable sense of operation
New sleek machined aluminum outer casing is used for a refined lens appearance. *The focus mechanism has been completely revised for enabling smooth focusing when using the manual focus and a comfortable sense of operation. *The hood is made of plastic.
Simple drip-proof construction for high reliability even when outdoors
This lens uses a simple drip-proof construction for preventing water from getting inside the lens. Combined with PENTAX digital SLR cameras also using a drip-proof construction enables use in rainy or foggy conditions, or other locations exposed to water for enhanced durability and reliability.
High delineation performance
This lens has a focal length equivalent to 153mm in the 35mm film format.

The FREE (fixed rear element extension) focusing system is used to minimize ghosting and flare and provide clear, high-quality images from the infinity end to macro distances. Closeups up to a maximum of 1:1 (1X) are possible. The working distance is longer than the macro of 50mm for enabling effective shooting of subjects that are difficult to approach.
Round iris diaphragm for natural out-of-focus (bokeh) effect
A new round iris diaphragm is used from open to F5.6. This reduces the beams of light when shooting point light sources for enabling a more natural out-of-focus (bokeh) effect.
SP (super protect) coating
A SP (super protect) coating is used on the front lens for repelling water and oils to enable shooting with peace of mind even in outdoor environments.
Quick-Shift Focus System
If you turn the focus ring after focusing by the AF, focusing instantly switches to the manual focus. This enables smooth focusing operations without the need for a switching operation.
An image circle is provided that supports 35mm format film SLR cameras.
