Sigma’s now legendary 50mm f/1.4 EX DG HSM has caused a revival of interest in the 50mm standard lens, and in so-called ‘prime’ lenses generally. Prime is a misuse of an optical term, but you can’t avoid it now and it’s neater than writing ‘fixed focal length’ every time. We now talk casually about prime lenses opposed to zoom lenses, and that is not the correct term as many modern zooms are actually varifocals, meaning they need a focusing adjustment if you change the focal length, which a true zoom does not. So, let’s just say prime for fixed focal length and zoom for anything with a variable focal length, and forget the pedantry. Almost any well-made prime, even of a simple construction, can give better contrast, resolution, even illumination and straight geometry than a zoom. When you move up to 24 megapixels and full frame lenses like 24mm f/2.8, 35mm f/2, 50mm f/1.7, 85mm f/1.8 or 135mm f/2.8 get very interesting. They are small, light and focus accurately with a bright viewfinder image. To buy a zoom which matches their typical quality, at any given focal length, may cost three times as much or more.

The penultimate stage in the SUPOY championship saw a real variety of approaches to the theme, though some people may have felt constrained by their glass, others have demonstrated some thought about using what they have to hand - with the final stage coming up next, the positions for the leaderboard are looking interesting. |

The DP range was first announced at Photokina in 2006; with a build up campaign and ongoing development it would be the beginning of 2008 before people could hold and use the pioneering camera. That gestation period saw the development of a new processor and pipeline for Sigma cameras; it also saw the details emerge that the DP was not to be a one-off, but part of a family of large-sensor compact cameras. Unique in the market still, the 28mm “wide” DP1 has been joined by a 41mm “standard” DP2. With a much shorter period from announcement to availability it looks like Sigma’s ownership of Foveon will allow the firm to react to market demands more effectively - and the DP2 demonstrates how the feedback from early DP1 users has shaped their latest camera. |

The fourth stage in the SUPOY championship saw some strong entries and a real improvement in submission numbers; I'm looking forward to the entries for the final two stages. The 50mm ƒ1.4 EX DG clearly inspired some strong competition and the seasonal weather no doubt helped with inspiration. Not only are the entries impressive for this one, I'm also pleased to see the technical information being given - I hope that other users will get some insight into how people are working with their cameras from this and benefit from it, so I do encourage people to provide as much information about their photography as possible. |

Sigma's DP1 digital compact camera broke new ground by offering a DSLR sensor in a point-and-shoot style body - it also offered the unique mix of a Foveon sensor and a good 28mm lens for only a little more than the equivalent 35mm glass. Despite this very single-purpose approach, Sigma felt that the DP1 could be given more versatility and announced the AML-1 close up lens accessory.

{mosimage width=125}Over 2008, a new class of computer system emerged and established itself as one of the few areas in computing to enjoy significant growth - the netbook, or “Small, Cheap Computer”. Devices of similar low power/high portability had been around with premium prices for some time, like the OQO or Sony Vaio UX - at the end of 2007 manufacturer and contractor ASUS launched the Eee range and within a stroke rendered this boutique systems irrelevant. 12 months on and there are now many variations, some of which are cheaper and offer more storage than the traditional “Image Tank” devices like the Epson P5000 - so is there room in your camera bag for one? |

Many beginners find digital photography rather challenging and rightly so. Today, more and more digital cameras are being created and it seems like the more digital cameras they make, the more difficult they become to use. You may not want or even need a camera with tons of features. It really depends on the type of pictures you plan on taking. Regardless of the camera you own or are planning to own, you should have a well-rounded knowledge of digital photography. Hopefully the following 20 tips for capturing digital images will prove to be useful in your quest for taking better photographs. |

{mosimage width=125} Fashion has come full circle for the 8mm fisheye. It’s almost a full-frame lens on the digital APS-C format. Richard Kilpatrick intruded on friends at Whitby’s Gothfest weekend with the original 8mm f4 EX DG - and has since been using the 8mm f3.5 EX DG in Sigma fit… To shoot portraits with an 8mm fisheye, you have to be willing to stick the lens mere centimetres from the subject’s nose – and they have to be willing to accept a cariacture worthy of any gothic abbey gargoyle in exchange! |

{mosimage width=125}The Sigma 150-500mm f/5-6.3 DG OS HSM is the company’s latest offering in the extreme telephoto zoom budget marketplace and it comes in with a few eyebrow raising improvements! Replacing the 170-500mm model that is now somewhat long in the tooth, the new lens, along with its shorter sister 120-400mm version has an excellent specification for its price. |

The first stage in the 2008/9 SUPOY awards had some strong entries, and the August holiday meant that judging and publishing the results and the winner of the 20mm f1.8 lens provided by Sigma UK for this stage has been slightly delayed. The winner and 9 placed images are published below. |
