Insects have been a long-time inspirational source for camera developers worldwide, because of the way their eyes are structured. Most insects have dozens of eyes that catch a wide array of images, which are then converted by the brain into the big picture. Flies can see almost 360 degrees around them, an ability tha... |

Everyone knows only too well that Leica is more of a luxury brand, providing high-end products especially for those for whom money isn't exactly an object.

The issue with optical devices in space is that the extremely low pressure determines the adhesive that keeps them in place to release gases that either contaminate the lenses or move the lenses a couple of microns out of their original setting place. The same effect can be obtained while subjecting the adhesive mate... |

Shorty after announcing that the DP1 is back on track, Sigma has quietly announced today the updated versions APO 70-200mm F2.8 II EX DG MACRO HSM and APO 50-150mm F2.8 II EX DC HSM. Don't expect anything grand though because the update is rather modest. The 35mm full-frame 70-200mm model has an extra ELD (Extra... |

Nikon is following Canon's "stabilized" footsteps by adding their Vibration Reduction technology to the less professional lenses.

Good news for Pentax DSLR owners who are craving for an all-around zoom lens like the Nikon 18-200mm or the Tamron 18-250mm. Speaking of Tamron, it appears that the new smc DA 18-250 f/3.5-6.3 ED AL [IF] is in fact the AF 18-250mm F3.5-6.3 Di II LD Aspherical (IF), which raises some questions regarding the famous smc... |

You might know this already or maybe not, but professional DSLRs and lenses are wickedly expensive (especially the lenses). Photographers who are not working for news agencies work long and hard in order to afford stuff like the Nikkor 400mm f/2.8 ED-IF II or the Canon EF 300mm f/2.8L IS. Photojournalists are luckier... |

Optically speaking, third party lenses can be as good as the Nikkors or Canon EFs, but they sometimes lack features like optical stabilizations and ultra-fast motors. Sigma is trying to compensate for this by upgrading its lineup with new and improved versions, albeit for now just for Nikon DSLR owners.The company ha... |
