The first Sony G Lens, the E PZ 18-105mm f/4 G OSS Lens. created specifically for E-mount cameras is true to its heritage, achieving outstanding resolution and contrast throughout the zoom range thanks to an advanced optical design incorporating two ED glass elements and three aspherical elements. From wide angle to medium telephoto, this power zoom lens covers approximately a 6x zoom range with a constant F4 aperture.
Optical SteadyShot Image Stabilization
Built-in Optical SteadyShot image stabilization compensates for camera shake that can blur images when shooting handheld. Sharp, clear night scenes or indoor shots in dim lighting can be captured without the need to boost ISO sensitivity and risk increased noise.
Lens-based optical image stabilization
Gyro sensors built into the lens detect even the slightest movement, and the stabilization lens is precisely shifted to counteract any image blur that might occur. The use of precision, quiet linear motors and technology inherited from high-end Sony professional camcorders results in exceptionally quiet, effective image stabilization that contributes to high-quality movies as well as stills.
Extra Low Dispersion Glass (ED)
Sony's Low Dispersion technology is engineered to reduce chromatic aberrations, which becomes more of a problem as focal lengths get longer. By eliminating the tendency of light of different colors to focus to different points at the image plane. This means your images will come out crisp and clear, with less of a chance of defracting light into an unwanted rainbow of colors. Take shots exactly like you want, without any flare-up or blurring.
Sony's aspherical lens design creates a more complex surface profile, while also reducing lens size and weight. Specially shaped “aspherical” elements near the diaphragm restore alignment of light rays at the image plane, translating to high sharpness and contrast even at maximum aperture. Well-designed aspherical elements can reduce the total number of elements required in the lens, thus reducing overall size and weight. The design further ensures consistent imaging performance throughout the entire focal range, while delivering incredible sharpness up to the periphery of the image.
Beautiful G Lens Bokeh with Circular Aperture
G Lenses are renowned for their beautifully smooth background bokeh. A 7-blade circular aperture design is part of the reason, enhancing smoothness and producing natural highlights. Smooth background defocusing can make the in-focus subject really stand out in images with almost three-dimensional depth.
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.
Zoom Technology and Control
Fingertip control of zoom speed via the zoom lever on the lens barrel or the zoom ring makes it possible to zoom smoothly while maintaining a sure, steady grip on the camera. This can be a significant advantage for consistent, stable handling, especially when shooting movies. Sony Handycam Technology is implemented into the lens to also help with smooth and quite zooming. Focusing benefits from the same type of pro-level technology, providing smooth, quiet operation that is also responsive. The length of the lens remains constant while zooming or focusing. Zoom reversing is available after software update.
