Features / Specifications
- HD coating
- This coating reduces the reflection rate up to 50% more than the conventional coating (compared to PENTAX multicoating) for reduced flare and ghosting even under backlighting and other adverse conditions where strong point light sources can enter the lens.
- Round iris diaphragm
- A 9-blade, round iris diaphragm is used. This enables natural reproduction of illumination and other scenes and softer out-of-focus (bokeh) effects for making the subject stand out more prominently from the background.
- ED (Extra-low Dispersion) Glass/Anomalous Dispersion Glass
- ED (Extra-low Dispersion) Glass and Anomalous Dispersion Glass are used to minimize color blurring over the entire zoom range and even at the edges of the image for providing superior resolution.
- Internal lens motor AF
- For the first time, the Limited series now uses a DC motor inside the lens barrel for providing a focusing mechanism. Compared to body AF, this focusing mechanism provides a quieter drive sound and smoother AF operation.
- Weather-resistant construction
- Photography when exposed to water or sudden rainfalls A weather-resistant construction is used for overcoming adverse conditions. The focus ring and zoom ring also have a weather-resistant design for preventing the entry of water.
- Machined Aluminum Material
- The lens barrel, cap, and hood use a machined aluminum material. You will feel the presence and elegance of the Limited series whenever you look at or touch this lens.
