Smoother, more natural defocusing can be obtained as a result.Īspherical lens design dramatically reduces spherical aberration while also reducing lens size and weight. α lenses overcome this problem through a unique design that keeps the aperture almost perfectly circular from its wide-open setting to when it is closed by 2 stops. Conventional aperture blades have flat sides creating unappealing polygonal shaped defocussed points of light. This 'bokeh' effect of the blurred background can be enhanced with circular aperture blades used in this lens. When changing your aperture to defocus the background, the light sources appear blurred. The reflection suppression characteristic of the Nano AR Coating is superior to conventional anti-reflective coatings, providing a notable improvement in clarity, contrast, and overall image quality. 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. Other advanced technologies, such as the Nano AR Coating and Super ED (extra-low dispersion) glass, elevate overall performance to an extremely high standard.Įffectively suppress reflections that can cause flare and ghosting with Sony's original Nano AR Coating technology. 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. Advanced optics and coatings with a 9-blade circular aperture deliver exceptionally smooth bokeh that G Lenses are renowned for. 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.
#Sony 90mm macro manual
Nauticam housing for A7II / A7RII / A7SII use Nauticam N100 Macro Port 105 #37126 and Nauticam focus gear SE90-F #37147.Nauticam housing for A7 / A7R / A7S use Nauticam N100 Macro Port 110 #37125 and Nauticam focus gear SE90-F #37147.In this context, the Sony 90mm Macro lens follows in the footsteps of the highly regarded Tamron 90mm, Tokina 100mm and Sigma 105mm macro lenses – quite an illustrious group to be part of. It offers a good working distance between the subject and the end of the lens, and has a narrow enough field of view so that backgrounds can be fairly concentrated and blown nicely out of focus. The 90-105mm focal length is a sweet spot for macro photographers. Sony FE 90mm f/2.8 Macro G OSS review – Features Now that Sony has released the FE 90mm f/2.8 Macro G OSS lens all that has changed, with this premium optic providing Alpha 7 users a dedicated macro lens. Until now, for anyone interested in macro photography, Sony’s own LA-EA adapters for Alpha-mount lenses or third-party adapters were the only way they could shoot macro images. However, for those times when speed isn’t as much of an issue, such as when shooting landscape or macro images, the use of third-party lenses has been a boon to the system and an affordable solution for DSLR photographers using the new full-frame E-mount system. There are some limitations to using DSLR lenses, such as the need to use manual focus with third-party lenses. Of course, this facility equally applies to other compact system cameras, but thus far, Sony is the only company to offer a full-frame sensor. Thanks to the E mount’s short flange distance, Sony Alpha 7 cameras are able to use many lenses originally designed for DSLRs.
