Lens Technology: XGM (eXpand Glass Molded Aspherical) lens elements

XGM lens elements allow to harmonize both fast-aperture and distinguishably high resolution by minimizing distortion and enhancing the sharpness of the image at its periphery

Not only minimizing geometric distortion and/or spherical aberration, it also enables the ability to attain higher resolution while making the overall mechanical dimensions smaller. TAMRON’s XGM is a nomenclature of the breakthrough technology which yields aspheres of larger apertures exceeding 55mm in diameter. Fast-aperture and distinguishably high resolution across the field are harmonized by virtue of deploying the XGM element while keeping the overall form factor to the smallest possible without compromising any performance criteria.
