The PENTAX-original HD coating on the lens ensures higher light transmittance than conventional multi-layer coatings. This helps to deliver sharp, clear images free of flare and ghost images, even in challenging lighting conditions.
The round-shaped diaphragm in the HD Pentax-FA 43mm f/1.9 Limited Lens produces a natural, beautiful bokeh effect in both the foreground and background of your images. This enhances the overall imaging performance, creating visually stunning effects.
The SP (Super Protect) coating is applied to the front surface of the lens to repel dust and stains. This helps to maintain the clarity of the lens and protect it from minor damage.
The aperture ring has been retained in the HD Pentax-FA 43mm f/1.9 Limited Lens, allowing users to utilize a variety of functions featured in K-mount film-format cameras. This adds versatility to the lens and enhances its usability.
The barrel, hood, and cap of the HD Pentax-FA 43mm f/1.9 Limited Lens are all made of high-grade aluminum. This material is meticulously machined for an attractive appearance and beautiful texture, ensuring the lens is not only functional but also aesthetically pleasing.
