The full-frame 90mm medium telephoto macro E-mount lens features built in image stabilization for sharp, clear images at up to 1:1 magnification, even when shooting handheld. Advanced optics and coatings with a 9-blade circular aperture deliver exceptionally smooth bokeh that G Lenses are renowned for. Sharp in-focus rendering is achieved with a floating focus mechanism that suppresses aberration equally at all focusing distances, whether the subject is far away or extremely close. Other advanced technologies, such as the Nano Ar Coating and Super Ed (extra-low dispersion) glass, elevate overall performance to an extremely high standard. Nano Ar Coating Effectively suppress reflections that can cause flare and ghosting with Sony's original Nano Ar Coating technology. This precisely defined regular nano-structure allows accurate light transmission, contributing to high-quality images, even more so than lenses with coatings that use an irregular nano-structure.
