Sigma announces new 18-250mm f3.5-6.3 DC Macro OS HSM zoom

media_1339748699275.png

After yesterday's announcement from Nikon of a 18-300mm f/3.5-5.6 ED VR lens at $999/£850, rival lens maker Sigma has announced a new 18-250mm f/3.5-5.6 zoom (actually an update) featuring offering many of the same features; optical image stabilization (unfortunately not included for Sony and Pentax as the bodies don't support OIS), ultrasonic focus motor, low dispersion glass and aspherical elements for nearly half the price, $TBA / £499. The lens focuses down to 35cm (45cm for the Nikkor) and weighs just 470g as opposed to 830g. The downside? Well it doesn't have quite the same reach (250mm vs 300mm) and it doesn't have sealing around the lens mount, but on paper at least these two lenses are very similar. We'll have to see how they perform optically.

For more information, please visit Sigma UK or Sigma Corp (USA).

Press release

The Sigma Corporation is pleased to announce the announce the new Sigma 18-250mm F3.5-6.3 DC MACRO OS HSM, a compact, high zoom ratio lens, covering wide angle, telephoto and macro photography.

By revolutionizing the optical and structural design of the Sigma 18-250mm F3.5-6.3 DC OS HSM, this new lens achieves a compact size and a minimum focusing distance of 35cm. Sigma’s newly developed material, Thermally Stable Composite (TSC), which maintains its size and structure in varying temperatures, is incorporated into the lens barrel.

Designed exclusively for digital SLR cameras, this versatile lens covers wide-angle to telephoto making it suitable for many types of photography. Its small size and huge focal-range make it perfect for travel photographers and those who like to keep equipment down to a minimum.

This is the first lens to use Thermally Stable Composite (TSC). This is a unique product that’s been developed in conjunction with a specialist manufacturer. This material is unique to Sigma and has metal like characteristics. Traditionally, Sigma use engineering plastic which is polycarbonate mixed with 20-30% glass. The advantages of this are its high resistance to impact, it’s lightweight and it doesn’t degrade over time. However, the drawbacks are its plastic feel and high dependency on temperature. In differing temperatures it expands and contracts considerably. As a result, a large gap is required between any metal/composite interface to allow for this expansion/contraction in size. The new TSC material has overcome this and is much more stable in varying temperatures. Consequently, a tighter construction can be achieved with thinner and lighter material.

Sigma’s own unique Optical Stabilizer (OS) function is incorporated into this lens. It offers effective correction of approximately 4 stops, overcoming camera shake even in close-up range photography.
Sony and Pentax mounts are not incorporated with OS function.

One SLD (Special Low Dispersion) glass element offers excellent correction of color aberration and three aspherical lenses, including a double-sided aspherical lens, prevent and correct all types of aberrations such as astigmatism, achieving high image quality throughout the entire zoom range. Sigma’s Super Multi-Layer Coating reduces flare and ghosting, ensuring sharp and high contrast images even in backlit conditions. The supplied petal-type hood can be attached to block out extraneous light which has a harmful influence on image rendering.

The close-up capability is improved with a minimum focusing distance of just 35cm throughout the entire zoom range and maximum magnification ratio of 1:2.9. When the APS-C size sensor is taken into consideration, the effective maximum reproduction ratio becomes 1:2.


The lens benefits from a Hyper Sonic Motor (HSM) to ensures fast and quiet auto-focusing.

This lens incorporates a brass made bayonet mount which has both high accuracy and solidity, the same as the mount of camera bodies. A special treatment to reinforce the strength is applied to the surface to ensure resistance to wear through long-term use.

*Sony and Pentax mounts do not incorporate Optical Stabilisation.

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…
