Pentax announce weather resistant (WR) 18-55mm & 50-200mm zooms




PENTAX UK is pleased to announce the launch of two compact, lightweight zoom lenses: the smc PENTAX-DA18-55mmF3.5-5.6AL WR, and the smc PENTAX-DA50-200mmF4-5.6ED 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-DA18-55mmF3.5-5.6AL 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-DA50-200mm F4-5.6ED 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.

Hasselblad H4D-60 review

UPDATE 18 May, 2012: Hasseblad is set to reduce the price on the H4D cameras by as much as $11,000 / 6,200 Euros on the H4D-60, bringing the price to 23,900 euros ($30,995 / £21,995). Please see here for more details.

The last couple of decades have been turbulent for medium format camera manufacturers, but now after several well-known names have withdrawn, the market looks healthy. Two new unexpected entrants, Leica and Pentax have added to the dynamic at opposing ends of the pricing scale, forcing the two established system players to compete fiercely in their traditional rarefied role as well as the entry-level.

Partnering with both Leaf and Mamiya, Phase One has developed a trio of entry-level Mamiya DM models starting at under $14k/ £9k while continuing to offer a wide range of Phase One and Leaf backs, up to 80-megapixels. Through various offers and incentives these backs, are most likely to be partnered with the 645DF body but they are in fact compatible with a wide range of …

Fujifilm IS Pro UV-IR DSLR review

Fuji’s IS Pro is the up-date to maker’s earlier S3 UV-IR camera, and like that particular camera, the IS Pro adopts a modified image sensor that’s not shielded from UV or IR light. Consequently, with various filtration methods, the IS Pro is designed for Ultraviolet (UVA), visible and near Infrared photography.

Although there is a healthy demand for DSLRs with IR capability especially, and there are number of independent vendors (mainly in the US, but the UK also) that offer IR dedicated and full-spectrum conversion of current Nikon and Canon bodies, it’s anticipated the IS Pro will appeal largely to the scientific and forensic communities. With the departure of the S3 UV-IR, Fuji’s IS Pro continues to be the only dedicated full-spectrum interchangeable lens based DSLR that has professional-level support from a camera maker. As well as official product support and 12-month warranty, for government agencies and the like, the OEM status of the IS Pro will be particularly reassuring an…

Introduction


Unlike the process of dithering liquid ink in an inkjet, dye-sublimation printers produce authentic continuous tone images with an analogous look like that of a conventional lab-produced print. They achieve this using thin c…
