A weather-resistant macro lens with high-quality exterior finish, designed for use with PENTAX SLR cameras
HOYA CORPORATION PENTAX Imaging Systems Division is pleased to announce the launch of the smc PENTAX-D FA MACRO 100mmF2.8 WR, an interchangeable macro lens designed for use with PENTAX digital and film-format SLR cameras. Combining a high-quality exterior finish with a PENTAX-original simplified weather-resistant construction, this new macro lens is especially useful for demanding outdoor applications.
Major Features
1. High-quality exterior finish with high-grade aluminum barrel
This macro lens features a high-grade chipped-aluminum barrel, and its exterior design has been greatly refined from that of the existing D FA-series lenses to deliver a more sophisticated, exclusive appearance. The entire mechanism of the focus ring has been reviewed and upgraded to assure flawless manual-focus operation.
2. Simplified weather-resistant construction for greater reliability outdoors
This macro lens features a simplified weather-resistant construction, which minimizes the intrusion of water and moisture into the lens barrel. By mounting the lens on a PENTAX weather-resistant digital SLR camera body, the user is assured of greater durability and reliability when shooting in rain or mist, as well as at locations subject to a spray or splash. The lens also features the PENTAX-original SP (Super Protect) coating on its front surface to repel dust, water and grease and to minimize fingerprints and cosmetic spots. These features make the lens ideal for all types of outdoor applications.
3. Rounded diaphragm blade to produce a beautiful bokeh
The PENTAX-D FA MACRO 100mmF2.8 WR is the first PENTAX interchangeable macro lens featuring a completely rounded diaphragm blade. This creates a natural, beautiful bokeh, while minimizing the streaking effect of point light sources.
4. High-quality image description
When mounted on a PENTAX digital SLR camera body, this lens offers a focal length equivalent to 153mm in the 35mm format. Inheriting the high-performance optics of the renowned smc PENTAX-D FA MACRO 100mmF2.8 lens, it delivers high-quality, true-to-life images, while minimizing annoying flare and ghost images — problems common in digital SLR photography. Its maximum magnification of life size allows the photographer to capture dramatic close-up images with great ease.
5. Other features
* A working distance of 13cm (in life-size applications) to facilitate the shooting of unapproachable subjects, such as insects
* The PENTAX-developed Quick-Shift Focus System for instant switching to manual-focus operation after the subject is captured in focus by the camera’s AF system
* An image circle accommodating the image size of 35mm film-format cameras
* Compatibility with the macro adapter included in the PENTAX AF160FC Dedicated Auto Macro Flash

Pentax K-7 Digital SLR Review
Pentax K-7: Focus and metering
The multi-segment metering has been upgraded immensely from 16 segments to 77 on the new model. Theoretically this ensures more accurate exposures due to the higher amount of portions that are taking a reading. The camera also compensates for the composition, format (landscape or portrait) and distance of the subject by using sensors located in the camera body.
Live-view on the K20D was great when the camera was released because it was a relatively new concept on DSLRs at the time but now it looks slow and clunky. The K-7 has had a revamp in the live-view area and now has face recognition and a faster AF system which could be a godsend to current Pentax DSLR live-view users. Out of face recognition, the K-7 uses contrast detection AF.
You can also feel confident using the viewfinder as Pentax have opted for a 100% view using the traditional method. They've also added a petaprism instead of a pentamirror which gives 0.92x magnification.

Pentax DA 18-55mm & DA 50-200mm lenses
Pentax UK is pleased to announce the launch of two compact, lightweight zoom lenses: the smc Pentax DA 18-55mm f3.5-5.6 AL WR, and the smc Pentax DA50-200mm f4-5.6 ED WR. Featuring a newly designed, simplified weather-resistant construction, these zoom lenses offer excellent reliability in various outdoor conditions — particularly rain, fog and mist.
Main features:
1. Simplified weather-resistant construction
These new zoom lenses feature a simplified weather-resistant construction designed to minimise the intrusion of water and moisture into the lens barrel. Mount on Pentax weather-resistant digital SLR camera bodies, assures the user of improved durability and reliability during shooting in rain, fog or mist.
2. SP coating to block dust and dirt
The front surface of these lenses is treated with Pentax-original SP (Super Protect) coating, which applies a special fluorine compound to the lens surface through a vapour deposition process. This SP coating not only repels dust, water and grease, but it also makes it easy to wipe off fingerprints and cosmetics.
3. Digital-SLR-exclusive optical design
Pentax has optimised the characteristics of these lenses — including lens coating, curvature and positioning of optical elements — to reproduce the finest possible digital images. As a result, they are practically free of flare and ghost images, and bring out the best in the Pentax digital SLR camera bodies they are used with. Their image circle is also perfectly proportioned to the size of the image sensor used in Pentax digital SLR cameras, helping to reduce the camera’s overall size and weight and guarantee outstanding cost performance.
4. Quick-Shift Focus system for instant AF/MF switching
After the subject is captured in focus by the camera’s AF system, the unique Quick-Shift Focus system allows the photographer to instantly switch to manualfocus operation for final pin-point focus adjustment.
5. Other features
1. Durable, dependable metallic lens mount
2. Lens hood with a PL (polarising filter) window included as a standard accessory
Overview of the smc Pentax DA 18-55mm f3.5-5.6 AL WR lens
This standard zoom lens covers focal lengths from 27.5mm wide angle to 84.5mm moderate telephoto (in the 35mm format). Incorporating a high-performance aspherical (AL) optical element and a super-low-dispersion glass optical element in its optics, it ensures outstanding image resolution and remarkable brightness, even at the edges, while effectively compensating various aberrations.
Overview of the smc Pentax DA 50-200mm f4-5.6 ED WR lens
This telephoto zoom lens covers focal lengths from 76.5mm moderate telephoto to 307mm super telephoto (in the 35mm format). Incorporating an extra-low dispersion (ED) glass optical element in its optics, it assures excellent description of the subject in various telephoto applications, including portraiture, sports/action and landscape, while effectively compensating chromatic aberration over the entire zoom range.
