Where precision and versatility meet, the FE 90mm f/2.8 Macro G OSS Lens stands out as a stellar choice for photographers and videographers alike. This full-frame, medium telephoto macro lens is designed for Sony's E-mount cameras and is engineered to deliver sharp, clear images at up to 1:1 magnification, even when shooting handheld, thanks to its built-in Optical SteadyShot image stabilization.The lens's advanced optics are complemented by a 9-blade circular aperture, which produces exceptionally smooth bokeh - a signature quality of Sony's G Lenses. Whether capturing portraits with a creamy background or the intricate details of close-up subjects, this lens renders out-of-focus areas with a pleasing aesthetic.A floating focus mechanism ensures consistent suppression of aberrations across all focusing distances, from infinity to extreme close-ups. This results in sharp, in-focus rendering that photographers can rely on, regardless of the distance to their subject.Sony's original Nano AR Coating technology is a key feature of this lens, effectively reducing reflections that can lead to flare and ghosting. The precision of this nano-structure coating allows for accurate light transmission, enhancing image clarity, contrast, and overall quality.The lens's circular aperture contributes to the beautiful bokeh effect by maintaining an almost perfectly circular shape from its widest setting to when it is stopped down by two stops. This design ensures smoother, more natural defocusing than conventional aperture blades.Aspherical lens elements are incorporated to minimize spherical aberration while also reducing the lens's size and weight. These elements help maintain high sharpness and contrast, even at the lens's maximum aperture, and contribute to a reduction in overall distortion.The internal focusing mechanism of the lens means only the middle groups of the optical system move to achieve focus. This design keeps the lens's length constant during focusing, provides faster autofocus, and maintains a short minimum focusing distance. Additionally, the filter thread at the front of the lens does not rotate, which is particularly convenient when using polarizing filters.A focus hold button on the lens barrel allows photographers to lock the focus at the desired distance, and this button can also be customized for preview functions through the camera's settings. The focus range limiter is another feature that saves time during autofocus by preventing the lens from 'hunting' through the entire focus range.The sliding focus ring offers a tactile control for switching between manual and autofocus modes, and together with the focus hold button, inner focus, and focus range limiter, it provides optimal control for macro photography. This is especially useful for capturing subjects like insects that require a careful approach.For video applications, the lens offers minimal focus breathing and operates quietly, which is essential for maintaining immersion in your footage. The lens-based optical image stabilization is driven by gyro sensors that detect even the slightest movement, and the stabilization lens is precisely shifted to counteract any potential image blur.Finally, the Direct Drive SSM (DDSSM) employs piezoelectric elements oscillating at ultrasonic frequencies to drive the focus lens groups. With two floating focus groups driven by independent DDSSM systems, the lens achieves precise positioning of the heavy elements required for macro photography. The system is remarkably quiet, making it suitable for capturing wildlife and for movie shooting, while also enhancing the precision of focus adjustments.The FE 90mm f/2.8 Macro G OSS Lens is a testament to Sony's commitment to high-quality imaging and precision technology, making it an indispensable tool for both professional and enthusiast photographers who demand the best in macro and portrait photography.
