Main Features of the HD PENTAX-FA Limited Lens

1. Advanced Imaging Performance with HD Coating
Equipped with Pentax's proprietary HD coating, this lens significantly enhances imaging capabilities. Unlike traditional multi-layer coatings, the high-grade HD coating allows superior light transmission while minimizing reflections. This feature effectively reduces the chances of flare and ghosting, particularly in challenging lighting environments, such as when shooting against the light. The result is an impressive increase in sharpness for this limited-series lens, ensuring your images remain vibrant and detailed.

2. Eight-Blade Circular Diaphragm for Stunning Bokeh
The HD PENTAX-FA Limited incorporates a newly designed circular diaphragm. With its eight blades, this diaphragm creates a visually pleasing bokeh effect at wider apertures, making your photographs stand out with soft and beautiful background transitions.

3. Premium Quality with Optimized Image Rendition
The lens embodies the true essence of Pentax's limited series design philosophy, delivering unique visual expressions. Achieving this level of quality required extensive image quality evaluations and numerical assessments through numerous captured photos. The exterior design is no less impressive; the lens barrel, hood, and cap display meticulous craftsmanship. Special attention has been paid to the texture, featuring a Shippoyaki-finished mount pointer that simplifies the lens mounting process.
