Features / Specifications

Superior distant view catching performance
An astronomical-type optical system with few lenses is used for enabling sharp, crystal-clear images particularly for photography of distant subjects. The optical system uses two ED (extra-low dispersion) glass lenses for correcting chromatic aberration and providing sufficient lighting for the edges and high resolution performance.
New "HD Coating" (Note 1)
A new high-performance multicoating "HD Coating" (Note 1) is used. This coating has less reflection and higher transmissivity than conventional coatings for providing sharp, crystal-clear images with reduced ghosting and flare even under backlighting and other adverse lighting conditions. Note 1: "HD" is abbreviation for High Definition. Definition = Transparency, detail, resolution, imaging performance
Dust-resistant and drip-proof construction (AW)
The lens barrel has been sealed in 29 locations for enabling a dust-resistant and drip-proof "AW (All Weather)" construction that prevents the entry of water and dust into the lens.
New design expressing the spirit of the HD series
The lens outside is a white color for a sense of presence and preventing heat haze from occurring inside the lens barrel under hot, sunny conditions. The strap mounting fixture uses a machined stainless steel material for providing a sense of elegance. The red alumite ring in the center of the lens barrel is the distinctive symbol of the HD series.
Enables use of C-PL (circular polarized light) filter
The lens body includes a detachable "filter mounting frame". When the supplied C-PL filter (40.5mm size, specifically for this lens) is attached, an operation ring can be installed for enabling rotation from the outside for enabling easy adjustment of polarizing effects.
Internal lens motor for smooth AF
The autofocus uses an internal lens AF motor (DC motor) for smooth driving action.
Quick-Shift Focus System
After focusing by AF, manual focus operation is possible without any switching operation.
SP (super protect) coating
A SP (super protect) coating is used for protecting the lens front surface from water and dirt and allowing any adhering dirt and oils to be easily removed.
Round iris diaphragm (Open to F11)
This lens uses a round iris diaphragm for reducing the beam of light when shooting point light sources and for enabling representation of round out-of-focus (bokeh) effect.
