RICOH IMAGING COMPANY, LTD. is pleased to announce the launch of the HD PENTAX-FA 50mmF1.4 and the smc PENTAX-FA 50mmF1.4 Classic. Developed for use with PENTAX K-mount digital SLR cameras, these standard lenses feature large-diameter optical elements to cover the full-frame image circle of K-mount cameras, despite their compact dimensions.
These lenses are designed based on the smc PENTAX-FA 50mmF1.4, which was launched in 1991 as a standard lens for film-format SLR cameras. In recent years, this base model has gained popularity because it delivers a distinctive image rendition at open and larger apertures — a rendition completely different from those produced by today’s digital-specific lenses.
The HD PENTAX-FA 50mmF1.4 features the latest, high-grade, multi-layer HD Coating to assure high-contrast images with edge-to-edge sharpness, while the smc PENTAX-FA 50mmF1.4 Classic produces a unique image rendition resembling that created by a lens designed 50 years ago. Although both feature the same focal length and open aperture, they are designed to produce distinctively different image renditions, providing photographers with a choice of product depending on their creative intention and/or application.
Main Features of the HD PENTAX-FA 50mmF1.4:
1. HD Coating to enhance imaging power
After a thorough review of the lens coatings applied to the ever-popular smc PENTAX-FA50mm F1.4, PENTAX decided to apply the latest, high-grade, multi-layer HD Coating to this new lens. Compared to conventional multi-layer coatings, this high-performance coating effectively reduces average reflectance and improves light transmittance, delivering clear, high-contrast images with minimal flare and ghost images, even in demanding lighting conditions such as backlighting.
2. New exterior design to match the latest digital SLR models
While retaining the dimensions of its base model — the smc PENTAX-FA50mm F1.4 — this lens features a totally new exterior design, similar to that of the latest DA and D FA-series lenses. This makes it a perfect match for K-series digital SLR cameras.
Main Features of the smc PENTAX-FA 50mmF1.4 Classic:
1. Distinctive imaging characteristics
Through intentional fine-tuning of the lens design, this lens has been designed to produce a unique visual effect commonly known as rainbow flare when it captures an image at open aperture and against strong backlight. It lets the photographer change the position and size of rainbow flare by shifting the relative position of the subject and light source, creating a unique, one-and-only visual expression not available with the latest lenses. By closing the aperture down to F4 or smaller, the photographer can capture sharper, crisper images that are free of not only rainbow flare, but also ordinary flare and ghost images.
2. Nostalgic design
This lens retains the exterior design of the smc PENTAX-FA50mmF1.4, featuring a black matte finish and a matte-black focus ring. It has no green ring — the symbolic design of recent PENTAX digital-specific lenses — to recreate the nostalgic appearance of an old-time lens from the film-format SLR era.
