Ricoh announces new $550 100mm F2.8 weather-sealed macro lens

Ricoh has announced the HD PENTAX-D FA MACRO 100mm F2.8ED AW lens, the company’s first macro lens to feature its All Weather (AW) design. This lens uses an all new optical construction while keeping roughly the same form factor as its 13-year-old predecessor.

The 100mm F2.8 macro lens offers a 153mm full-frame equivalent focal length on Ricoh’s APS-C Pentax DSLRs and is constructed of 10 elements in 8 groups, including one Extra-low Dispersion (ED) element and two Anomalous Dispersion elements to correct for various aberrations and fringing. The lens also features Ricoh’s High Definition (HD) Coating and Super Protect (SP) Coating. The HD Coating is designed to minimize reflections within the lens design while the SP Coating protects the front element by repelling dirt and water from the front element (as much as a coating allows).

Autofocus within the lens is driven via a new Fixed Rear Element Extension (FREE) focusing system that results in a minimum focusing distance of 13cm (5.1”) for a 1x magnification ratio. The lens features Ricoh’s Quick-Shift Focus System, which makes it possible to quickly nail focus with autofocus, then switch to manual focus for fine-tuning focus.

Below is a sample gallery of images provided by Ricoh Japan:

The lens has an aperture range of F2.8 through F32, uses a 49mm front filter thread and has a nine-blade aperture diaphragm. It measures 65mm (2.6”) in diameter by 80.5mm (3.2”) long and weighs approximately 387g (13.7oz) with the lens hood.

The lens will be available starting ‘late November’ on Ricoh’s online shop and through authorized Ricoh retailers for $549.95. In addition to the standard black model, a limited-edition silver model – limited to just 300 units – will also be available in early November for $549.95.

Ricoh Announces HD PENTAX-D FA MACRO 100mm F2.8ED AW Lens

Macro lens for use with PENTAX digital SLR cameras features new optical design for greatly improved imaging power; Special-edition silver model to be available in a limited quantity of 300 units worldwide

PARSIPPANY, NJ, October 19, 2022 -Ricoh Imaging Americas Corporation today announced the HD PENTAX-D FA MACRO 100mm F2.8ED AW lens—the first PENTAX macro lens to feature All Weather (AW) dustproof, weather-resistant construction. Incorporating a new optical design developed using the latest optical design technologies, the lens optimizes image resolution and contrast, even at open aperture, and delivers clear, high-quality images.

When mounted on a dustproof, weather-resistant PENTAX digital SLR camera body, the new HD PENTAX-D FA MACRO 100mm F2.8ED AW lens creates a highly dependable, durable imaging system that performs superbly in demanding shooting conditions — such as snow, mist, rain, or in locations prone to splashing or spraying water.

Despite the new optical design and AW construction, the new lens is nearly as compact as its predecessor (the smc PENTAX-D FA MACRO 100mm F2.8 WR). It features a new exterior design and incorporates the PENTAX-original Quick-Shift Focus System, enabling the photographer to instantly shift the focus mode from auto to manual after the subject has been captured in focus by the camera’s autofocus system.

Pricing and Availability

The HD PENTAX-D FA MACRO 100mm F2.8ED AW black lens will be available in late November 2022 at www.us.ricoh-imaging.com as well as at Ricoh Imaging-authorized retail outlets for the manufacturer’s suggested retail price of $549.95.

In addition to the standard black model, the HD PENTAX-D FA MACRO 100mm F2.8ED AW lens will also be available in a special-edition silver model — limited to just 300 units worldwide. The special-edition silver model will be available in early November 2022 at www.us.ricoh-imaging.com for the manufacturer’s suggested retail price of $549.95.

Main features of the HD PENTAX-D FA MACRO 100mmF2.8ED AW

1. Exceptional imaging performance made possible by the latest optical design technologies

The lens incorporates one ED (Extra-low Dispersion) glass optical element and two Anomalous Dispersion glass optical elements to compensate for various aberrations and minimize the generation of the unwanted purple fringe effect. This is coupled with the high-grade, multi-layer HD (High Definition) Coating, which significantly reduces average reflectance in the visible ray spectrum to less than 50% compared to conventional models, and the innovative FREE (Fixed Rear Element Extension) focusing system. All together, these technologies effectively reduce the generation of flare and ghost images over the entire focus range — from minimum focusing distance to infinity — and deliver clear, high-quality images. The lens also provides life-size magnification in close-range shooting to capture dramatic, fine-detailed close-up images.

2. Dustproof, weather-resistant AW construction for exceptional outdoor shooting reliability

Ready for adverse weather conditions, the lens features dustproof, weather-resistant AW (All Weather) construction for the first time in a PENTAX macro lens. This dependable construction prevents the intrusion of dust and moisture into the lens body, using six sealing parts to optimize airtight performance. When mounted on a dustproof, weather-resistant PENTAX digital SLR camera body, it creates a highly dependable, durable imaging system that performs superbly in demanding shooting conditions — such as snow, mist, rain, or in locations prone to splashing or spraying water.

3. Exclusive exterior design and outstanding operability

The lens has an attractive, stylish appearance, with metallic exterior parts meticulously machined from high-grade aluminum. Its focus ring features the PENTAX-original Quick-Shift Focus System, which allows the photographer to instantly shift the focus mode from auto to manual after the subject has been captured in focus by the camera’s autofocus system. This single- action operation assures a smooth, comfortable focus-mode switching maneuver during manual- focus shooting for dramatically improved operability.

4. Compact, lightweight design for superb maneuverability

Despite the improved imaging power made possible by the new optical design and outstanding AW construction, the lens is nearly as compact and lightweight as the smc PENTAX-D FA MACRO 100mm F2.8 WR (launched in December 2009), with outstanding weight distribution, ergonomics and maneuverability.

5. Other features

  • A working distance of 5.1 inches (13 centimeters), at life-size magnification, to facilitate the shooting of typically uncooperative subjects, such as insects
  • Individual serial number assigned to each lens: black model starts at 0000001, the silver model starts at 1000001
  • Circular diaphragm to produce a natural, beautiful bokeh (defocus) effect from open aperture to F5.6, while minimizing the streaking effect of point light sources
  • SP (Super Protect)Coating applied to the front optical element to keep the front surface free of dust or stains
