According to latest rumors coming from m43rumors, Sigma will announce new lenses at September(Photokina), currently we have no info about the upcoming lenses. Just few days ago we have posted that Lens giant Schneider Kreuznach have now started working on lenses for mirrorless (M4/3 system) and 14mm F2.0, 30mm f/1.4 and 60mm f/2.4 macro Schneider Kreuznach lenses for M4/3 system may be announced at photokina. (See more details here) via – 43Rumors sigma announced compact 18-250mm lens, it covers a wide range from wide, telephoto and Macro photography, the new 18-2500mm lens features OS (Image stabilization) and ‘Thermally Stable Composite’ (TSC) exclusively by Sigma to avoid barrel expansion in extreme temperatures.
The new 18-250mm F3.5-6.3 DC Macro OS HSM lens is also equipped with Super Multi-Layer Coating to reduce flare and ghosting, a Hyper Sonic Motor (HSM) to ensure fast and quiet auto-focusing, and a rounded, seven-blade diaphragm to create an attractive round blur to the out of focus areas. The lens features a brass-made bayonet mount applied on the surface to reinforce strength for long-term use and enable high accuracy and solidity.
The DP1 Merrill features a wide, 19mm F2.8 lens, which is the equivalent to a 28mm lens on a 35mm SLR camera. The DP2 Merrill, however, offers a 30mm F2.8 lens, which is the equivalent to a 45mm lens on a 35mm camera. Both cameras are compact and lightweight, and feature Sigma’s own “F” Low Dispersion (FLD) glass, which performs like fluorite glass and significantly improves lens performance, as well as Super Multi Layer Coating to reduce flare and ghosting. With the 46-megapixel, full-color Foveon X3 Direct Image Sensor, the new DP cameras capture all primary RGB colors at each pixel location with three layers, which results in incredibly detailed images with a three-dimensional feel. The Video mode is really poor, DP1M and DP2M can record VGA movie only, both compacts come with a A large, highly visible three-inch TFT color LCD monitor. |
