Pentax K-01 review
smc PENTAX-DA 40mm F2.8 XS With an exterior design by world famous designer
Marc Newson, this ultra-thin 40mm prime lens (equivalent to 61mm in the
35mm format) measures a mere 9.2 millimeters in length and weighs just 52g.
It’s maximum aperture of F2.8 produces sharp, bright images in a wide
range of applications, including snapshots, scenic photos, portraits, and
even incident-light indoor shooting. Nine rounded aperture blades produce
extraordinarily smooth, natural bokeh. PENTAX Super Protect (SP) coating on
the lens surface helps repel dust, water, and grease, making the lens
easier to clean.
