![]() ![]() ![]() Light falloff is essentially a non-issue for the 90mm ƒ/2.8 macro when mounted on the sub-frame NEX-7 the only corner shading of note is found at the ƒ/2.8 setting, where the corners are a 1/4-stop darker than the center. Both the NEX-7 and A7R employ in-camera correction for chromatic aberration, corner shading and distortion, and to give you a fuller picture of lens performance we've shot our sample images with and without these settings enabled. There's little chromatic aberration to speak of from both the test results and looking at the sample images. Mounted on the full-frame A7R, there's a trace of corner softness at ƒ/2.8, but stopping down to ƒ/5.6 provided incrementally better corner sharpness until it became tack-sharp.ĭiffraction limiting begins at ƒ/11, but you'll be hard-press to notice any impact on sharpness until ƒ/16, where generalized softness begins to set in. When used on the NEX-7 with its APS-C sensor, the images shot were tack-sharp from ƒ/2.8 onward. Our review sample of this lens proved to be exceptionally sharp, even when used at its widest aperture setting of ƒ/2.8. The lens is scheduled to start shipping in July, 2015, ships with a round lens hood, and will be priced at approximately $1,100. Reliable operation in a variety of conditions is ensured by a design that prevents dust and moisture from entering the lens.The Sony FE 90mm ƒ/2.8 Macro G OSS will fit on both APS-C and full-frame E-mount Sony bodies on the NEX-7, the lens provides an effective field of view of around 135mm. 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. In some ways, lens requirements for movie-making are more demanding than for stills. 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. 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 handling 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. 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. ![]()
