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. Advanced optics and coatings with
a 9-blade circular aperture deliver exceptionally smooth bokeh that G Lenses
are renowned for. 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. Other advanced
technologies, such as the Nano AR Coating and Super ED (extra-low dispersion)
glass, elevate overall performance to an extremely high standard. From the

CoatingEffectively suppress reflections that can cause flare and ghosting with
Sony’s original Nano AR Coating technology. 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. 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.Circular
ApertureWhen changing your aperture to defocus the background, the light
sources appear blurred. This ‘bokeh’ effect of the blurred background can be
enhanced with circular aperture blades used in this lens. Conventional
aperture blades have flat sides creating unappealing polygonal shaped
defocussed points of light. 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. Smoother, more natural defocusing can
be obtained as a result.Aspherical lens elementsAspherical lens design
dramatically reduces spherical aberration while also reducing lens size and
weight. Spherical aberration is a slight misalignment of the light rays
projected on the image plane. This is caused by differences in refraction at
different points on conventional spherical lenses which degrade image quality
in large-aperture lenses. Specially shaped “aspherical” elements near the
diaphragm restore alignment of light rays at the image plane, maintaining high
sharpness and contrast even at maximum aperture and can also be used at other
points in the optical path to reduce distortion. Well-designed aspherical
elements can reduce the total number of elements required in the lens, thus
reducing overall size and weight. Internal focusingOnly 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.Focus hold buttonOnce you’ve adjusted focus to where you want it,
pressing this button on the lens barrel will keep the lens locked to that
focusing distance. The preview function can also be assigned to this button
through the camera’s custom settings.Focus range limiterThis function allows
you to set a limit on the focusing range which can save you time during AF
operation as the lens will not ‘hunt’ through the entire focusing range. In
macro lenses, this limit can be on either the near or far range (as pictured).
In the SEL90M28G, the limit is set on far ranges only. Sliding Focus RingThe
focus ring slides back and forth to select manual or auto focus which together
with a focus hold button, inner focus, and a focus range limiter provide
optimum control for macro photography making it easier to shoot insects and
other subjects that cannot be approached too closely. Minimal focus breathing
and quiet operation are also advantageous for shooting movies.Lens-based
optical image stabilizationGyro 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.Direct Drive SSM (DDSSM) for quiet,
precise focusingQuiet, precise DDSSM (Direct Drive SSM) focus drive - employs
piezoelectric elements oscillating at ultrasonic frequencies to drive the
focus lens groups. In this case two floating focus groups are driven by
independent DDSSM systems for precision positioning of the relatively heavy
lenses required for macro photography. The DDSSM drive system is remarkably
quiet, making it ideal for animal and insect photography, as well as for
movies. It also improves the precision of “focus wobble” employed to achieve
optimum focus when shooting movies. 2015 Sony Electronics Inc. All rights
