Sony FE 90mm f/2.8 Macro G OSS Full-Frame E-Mount Macro Lens with Software Suite and Accessory Bundle (4 Items) - SEL90M28G_K25

• Bundle Includes: Sony FE 90mm f/2.8 Macro G OSS Full-Frame E-Mount Macro Lens, Photo, Video, and Art Suite v.3.0, Lens Cleaning Kit, and 64GB SDHC Canvas Select Plus Memory Card Aspherical Lens Elements: Aspherical lens design dramatically reduces spherical aberration while also reducing lens size and weight. Spherical aberration is a slight misalignment of the light rays projected on the image plane. This is caused by differences in refraction at different points on conventional spherical lenses which degrade image quality in large-aperture lenses Nano Anti-Reflective Coating: Effectively suppress reflections that can cause flare and ghosting with Sony’s original Nano anti-reflective 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 Internal Focusing: Only the middle groups of the optical system move to achieve focus, so the overall length of the lens does not change. Other important benefits include fast autofocusing and a short minimum focusing distance. Also, the filter thread at the front of the lens does not rotate, which is convenient if you’re using a polarizing filter Sliding Focus Ring: The focus ring slides back and forth to select manual or auto focus which together with a focus hold button, inner focus, and a focus range limiter provide optimum control for macro photography making it easier to shoot insects and other subjects that cannot be approached too closely
