Sigma unwrap 50-200mm F4-5.6 DC OS HSM



Sigma Corporation is pleased to announce the new SIGMA 50-200mm F4-5.6 DC OS HSM.

This compact high-performance telephoto zoom lens incorporates Sigma’s own Optical Stabiliser function. The lens incorporates SLD (Special Low Dispersion) glass in the front lens group and is equipped with an inner focusing system to provide high image quality throughout the entire zoom range. The Super Multi-Layer Coating reduces flare and ghosting and provides high contrast images.

The incorporation of HSM (Hyper Sonic Motor) ensures quiet and high-speed auto focus. The OS function effectively eliminates the effects of camera shake so subjects can be easily and clearly seen in the viewfinder as well as in the image. It allows the use of shutter speeds approximately 4 stops slower than normal for steady, handheld photography. For Sony and Pentax mounts he built-in OS System operates in conjunction with a camera body equipped with an anti-shake function and can be used as an alternative with cameras having built-in image stabilisation.

This lens has a minimum focusing distance of 110cm (43.3 inches) throughout the entire zoom range and a maximum magnification ratio is 1:4.5. An inner focusing system eliminates front lens rotation, making it suitable for use with circular polarising filters.

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of decades have been turbulent for medium format camera manufacturers, but now after several well-known names have withdrawn, the market looks healthy.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