![]() ![]() Everything’s wrapped up in a robust, weather-resistant casing and high-tech Nano AR Coating is applied to minimize ghosting and flare. Optical finery includes an aspherical lens element, an ED (Extra-low Dispersion) element and a Super ED element. This avoids the risk of the front of the lens casting a shadow over the subject in macro photography. Focusing is fully internal, so the physical length of the lens doesn’t extend at short focus distance. There’s also a customizable AF hold button and switches for optical stabilization on/off and autofocus range limiting, with which you can lock out either the short or the long end of the total travel. Switching between auto and manual focusing, the latter often being preferred in macro shooting, you just need to snap the control ring backwards or forwards - a trick often used in Tokina lenses amongst others. Autofocus is driven by a DDSSM (Direct Drive Super Sonic wave Motor) that’s quick, quiet and highly accurate even for extreme close-ups. This Sony macro lens has a pretty impressive feature list. It produces very sharp images with very little field-curvature although for optimal results it should be stopped down to f4.0 when shooting at closer distances. Sony FE 90mm f/2.8 Macro G OSS (Black) at Amazon for $1,098 Sony’s FE 90mm f2.8 Macro G OSS may be a few years old now, but remains a very good macro lens which also doubles up as a light telephoto.Reliable operation in a variety of conditions is ensured by a design that prevents dust and moisture from entering the lens.Lens construction: 15 elements in 11 groups Minimal focus breathing and quiet operation, for example, are essential for movie shooting. Sony goes the extra mile to ensure that lenses that will be used with movie-capable cameras will deliver the necessary performance. Lens requirements for moviemaking are more demanding than for stills in some ways. ![]() The filter thread at the front of the lens does not rotate, which is an advantage when using a polarizing filter. In addition to making handing easier, that means faster autofocus and shorter minimum focusing distance. In an inner focus design only internal lens elements move when focusing so the total length of the lens does not change. The medium telephoto focal length of this lens gives it an ideal working distance at macro magnifications, making it easier to capture impressive macro images of insects and other subjects that cannot be approached too closely. Selections are ∞ ~ 0.5 meters for distant focusing, 0.5 ~ 0.28 meters for close focusing, and FULL for full-range focusing. The Focus Range Limiter selector can be set for near and/or far focusing, depending on the subject, limiting focusing range and thereby maximizing autofocus speed. The focus hold button can be used to lock focus even when shooting in the continuous AF mode. Pressing the focus hold button conveniently located on the lens barrel instantly locks focus at the current setting and keeps it there until the button is released. A non-slip surface ensures reliable operation. With this lens the focus ring, where your hand normally rests while shooting, simply slides back and forth to switch between manual and auto focus. If you have to remove your eye from the viewfinder to switch between auto and manual focus you’re likely to lose the shot. ![]() ![]() The heavy stabilization lens is driven by a responsive linear motor for fast, precise stabilization. This system is remarkably quiet, and is ideal for animal or insect photography as well as movies.Īlthough a tripod is usually considered necessary for sharp macro photography, built-in OSS (Optical SteadyShot) image stabilization makes it possible to shoot sharp macro images handheld. Two focus groups in a floating focus configuration are driven by an innovative DDSSM (Direct Drive Super Sonic wave Motor) system for smooth, precise positioning of the relatively heavy lenses that make full frame macro magnification possible. Precise, quiet focus for stills and movies The floating system reduces the size of the lens while maintaining outstanding clarity throughout the image area, from infinity to the closest focusing distance. Macro lenses are often used over a wide range of focusing distances, so a floating focus mechanism has been implemented for optimum suppression of close-focus aberration. Image-wide clarity from macro to infinity Individual calibration of each lens ensures optimum compensation for spherical aberration, resulting in smooth rendering of edges without a trace of ugly “nisen bokeh.” A nine-blade circular aperture also contributes to great looking bokeh. Beautiful background bokeh is synonymous with the G Lens name, and it can really make the subject stand out. ![]()
