FEATURES

 

Achieving high-image quality/high-performance and compact size

9 elements in 6 groups, including a DSA lens that incorporates highly-accurate production technology; and an HR (High Refractive index) lens, that features high spherical aberration correction capability, are packed into a 35.5mm, 120g compact body. Boasts sharp, high-contrast image throughout the image area even at F1.8 aperture. State-of-the-art technology and know-how acquired through years of experience made it possible to achieve this level of image quality and high performance whilst ensuring a small size.

 

Optical performance equals to the High Grade Lens ED 12mm F2.0

ZERO Coating eliminates ghosts and flares

ZERO (Zuiko Extra-low Reflection Optical) Coating is applied to the lens surface to eliminate ghosts and flares that used to be difficult to reduce because of their high transparency. ZERO Coating boasts clear image quality even under challenging conditions such as backlit conditions.

 

Bright F1.8 aperture and in-body image stabilisation are effective under low light conditions

All Olympus OM-D and PEN cameras feature an in-body image stabilisation system. When combined with the fast F1.8 lens, blur-free images are easy even when shooting sunsets, low-light indoor scenes, and other locations where flash photography is not permitted (such as zoos and aquariums).

 

The MSC (Movie and Still Compatible) mechanism enables fast, quiet autofocusing

 The high-precision axis hanging method supports the MSC mechanism

The MSC (Movie and Still Compatible) mechanism is the latest in optical design technology for achieving fast and silent focusing with a lightweight form and minimum number of lenses. The gears have been removed, eliminating operational noise. A sub-micron precision metal axis (shaft) and feed screw (screw drive) are used for efficient, direct driving of the lightweight focusing lens. Enabling faster and quieter autofocusing.. This lens employs an inner focusing system that uses the MSC mechanism. It performs autofocusing by optimally controlling the three small, lightweight lenses. Thanks to this smooth AF system, users can comfortably shoot both still images and movies.

 

The advanced snapshot focus mechanism lets you shift the focusing point to a specific distance.

The snapshot focus mechanism enables you to take snapshots easily. Sliding the focus ring towards you to a specific distance reveals the distance markers engraved on the lens barrel as the focus point moves to a point on the distance marker. This mechanism allows quick deep-focus shooting, in which both subject and background are in focus, and quick no-finder shooting.

Sophisticated textured metallic finish for a stylish, classic look in a highly compact design

 PEN Lite E-PL5 + 17mm F1.8 and LH-48B lens hood

The solid yet comfortable-to-hold texture of the metal exterior, and the condensed, drifting, high quality feeling unique to a precision device were developed to ensure the camera remains stylish as the years pass. The metal lens hood and lens cap were specifically designed to accentuate the camera’s style.

  • The LH-48B metal lens hood and the LC-48/LC-48B metal lens cap cannot be used together.
  • If the VF-1 Optical Viewfinder is used with the LH-48B Metal Lens Hood, significant vignetting will occur in the field of view frame. Even when the LH-48B is not mounted, the lens may be visible in the visual field with certain cameras.

Depth of field

When focusing on a subject, there is an area behind and in front of the focused point that is also in focus. This area is called depth of field. The amount of area behind a focused point will always be greater than the area in front of the focused point regardless of aperture. Depth of field becomes deeper when the focal length is short (wide-angle lens), the focusing distance is long and aperture is small.
