50mm f/1.8g Lens by Nikon Now For Real
This stealth lens is the latest version of the classic Nikkor f/1.8 50mm released back in 1978.
The first Nikon 50mm f/1.8 lens with autofocus that provides instant override for manual-focus just by grasping the focus ring. Additionally it's the first 50mm Nikkor f/1.8 that will autofocus on Nikon's least expensive DLSR cameras such as the Nikon D3100 and D5100.
Nikon's new lens first new optical engineering since 1978.of an f/1.8 50mm lens.
Previous 50mm lenses employed 6 spherical elements, whereas this new lens sports 7 elements, including an aspherical lens element.
All prior 50mm f/1.8 lenses have always been first-rate optical performers. Although
name-droppers abstain from them by favoring the f/1.4 and f/1.2 lens, experienced photographers know these less expensive f/1.8 Nikkor lenses can be even a little sharper, and sans the barrel distortion associated with those faster lenses.
My old f/1.8 50mm AF-D consistently remained one of my favorites and I have a suspicion this new 50mm will also fall into that category.
The distortion is about 4 times worse on this f/1.8g, when compared to the Nikkor 50mm f/1.8d, a
visible 1.3% as compared to 0.3% barrel distortion for the f1/8d.

AF-S Autofocus lens featuring a Silent wave,
coreless, integrated, focus motor Basically an
updated AF-I Autofocus-Silent sporting a "Silent Wave Motor" (ultrasonic) to
focus near silently and fast.

Aspherical lens elements
- Nikon unveiled the first lens in 1968 featuring aspherical camera lens elements. What makes them different? Aspherical lenses all but eliminates the issues of coma and related kinds of lens aberrations
even when employed at the maximum aperture.
DX - NIKKOR - Compact and lightweight
Nikon DX lenses feature a lesser image circle and are specifically created and
optimized for the Nikon D-series, digital SLR camera bodies. An ideal option for
photographers and enthusiasts who require shooting of expansive landscapes with
Nikon DX DSLR
G - labeled after the f-number.
All the newer AF lenses, including AF-S and specifically G, are also D.
Nikon no longer makes an effort to mark the D.
G-lenses contains no aperture ring, therefore aperture may only be
electronically controlled by the camera and only autofocus camera bodies
featuring function dials have the capacity to control G lenses
IF- Internal Focusing
The ability to have a lens focus while it's size remains unchanged. Nikon’s
IF engineering allows that to happen. All internal optical travel is contained
within the inside of the non-extension lens container.
M/A mode
AF-S Nikon lenses include the exclusive Nikon M/A focus function, that permits
switching from auto to manual focus virtually without time lag - even while the
AF servo is in operation regardless of the AF mode in play.
RD- Rounded 7 Blade Diaphragm
Soft-focus images of point light resources create accepted polygonal shapes that
mirror the form of the cavity produced by the diaphragm blades..
RF - Rear Focusing
Nikon’s Rear Focus system divides all lens elements into express lens groups,
allowing only the back lens group to move for focus purposes
SIC - Nikon Super Integrated Coating
Nikon uses an elite multilayer lens coating to augment the operation of its
lens elements which also helps diminish ghosting and flare to minute levels.
Nikon Super Integrated Coat also accomplishes several purposes,
SWM- Silent Wave Motor
Nikon AF-S engineering is yet one more rationale why professional
photographers like Nikon telephoto optical lenses.
