Ricoh announces GR LENS A12 28 mm F2.5
A new GXR camera unit featuring a GR Lens and an APS-C size CMOS sensor
Exhibited at photokina 2010

Tokyo, Japan, September 21, 2010—Ricoh Co., Ltd. (president and CEO: Shiro Kondo) today announced the development and release of GR LENS A12 28 mm F2.5, the fourth camera unit in the GXR interchangeable unit system. This product is being announced and exhibited at the photokina 2010 exhibition held in Cologne, Germany, beginning September 21, 2010.
Introduced in December 2009, the GXR is a revolutionary new interchangeable unit camera system in which lenses can be changed by mounting camera units that integrate lens, image sensor, and image processing engine into a single unit. In addition, to fully utilize this system's unique ability to accommodate interchangeable units other than camera units, Ricoh is also investigating possibilities for development of a variety of other devices.
The new GR LENS A12 28 mm F2.5 brings together a newly developed 28 mm wide-angle fixed focal length GR Lens, an APS-C size CMOS sensor, and the proven GR Engine III image processing engine to create a unit with high flexibility, high image quality, high-speed shooting ability, and high power of expression.

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of decades have been turbulent for medium format camera manufacturers, but now after several well-known names have withdrawn, the market looks healthy.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…
