Product Specifications

Basic Information

Product Features

The large-aperture ultra-wide-angle zoom lens of the high-performance "★ (Star)" series, which pursues high descriptive performance with a maximum aperture of F2.8 across the entire zoom range.

- Large aperture lens with a maximum aperture of F2.8
Despite its compact size, this ultra wide-angle lens with a focal length of 11-18mm (equivalent to 17-27.5mm in 35mm format) allows you to capture magnificent and dynamic expressions. With a bright maximum aperture of F2.8 across the entire zoom range, the lens is also powerful for shooting starry landscapes. The minimum focusing distance of 30cm allows for close-up photography that emphasizes a three-dimensional effect by taking advantage of the out-of-focus background.

- HD Coating" for enhanced descriptive performance
The "HD Coating" is a high-performance multi-coating that suppresses average reflectance in the visible light range to approximately 50% or less compared to conventional coatings, effectively reducing ghosting and flare under backlit and other harsh lighting conditions.

- Optimal Structure for Landscape and Starscape Photography
When the focus clamp is turned on, the focus position does not move even when the focus ring is turned. This structure enhances ease of use when shooting landscapes and star scenes, which require precise focusing and long exposures. In addition, the layout of the lens is designed to provide enough space for the heater wire to prevent condensation from interfering with the focus ring operation, and even the lens is made of metal to ensure effective heat transfer from the heater. The design of the lens is also made of metal so that the heat from the heater can be effectively transmitted.

- Dustproof and drip-proof construction
The lens is designed to be dustproof and drip-proof to prevent water droplets and dust from entering the lens. Combined with a dustproof and drip-proof Ricoh digital SLR body, the lens offers improved durability and reliability in rain, fog, and splashing water.

- Quiet and smooth-operating autofocus thanks to the use of a DC motor

- 9-element circular aperture suppresses glow when shooting point light sources and produces a soft bokeh effect from maximum aperture to F4.5 at the wide-angle side and from maximum aperture to F5.0 at the telephoto side

- The Quick-Shift Focus System allows manual focusing without switching between auto-focus mode and auto-focus mode while the shutter release button is pressed halfway down.

- SP (Super Protect) coating on the front of the lens to resist stains
