Nikon added yet another two-letter abbreviation to its lens lexicon today – PF – which stands for "Phase Fresnel." Below you'll find information on the new technology.
From Nikon USA: Phase Fresnel
The PF (Phase Fresnel) lens, developed by Nikon, effectively compensates chromatic aberration utilizing the photo diffraction phenomenon*. It provides superior chromatic aberration compensation performance when combined with a normal glass lens. Compared to many general camera lenses that employ an optical system using the photorefractive phenomenon, a remarkably compact and lightweight body can be attained with less number of lens elements.
A general interchangeable lens forms an image on an imaging plane, using the photorefractive phenomenon. The degree of light refraction differs depending on the color (wavelength), and image formation is performed in the order of blue (B), green (G), and red (R) starting with the portion near the lens (see the diagram below). The color deviation referred to as chromatic aberration induces color bleeding, resulting in a deterioration of observed or captured images.
With PF (Phase Fresnel) lenses, on the other hand, image formation is performed in the order of red (R), green (G), and blue (B) starting with the portion near the lens (see the diagram below). By combining the PF (Phase Fresnel) lens with a refractive lens, chromatic aberration can be effectively compensated. Chromatic aberration compensation with the PF (Phase Fresnel) lens B&H

From Adorama: New wireless speedlight flash units with all the benefits of an external battery pack are available in full manual, Canon TTL and Nikon TTL models, along with the Zoom Li-on Flash Commander Transmitter and Receiver Set, and other accessories New York, NY – January 6, 2015
– Adorama, one of the world’s largest photography, video, imaging and electronics retailers, has expanded the Flashpoint lighting line once again with the launch of Zoom Li-on, a collection of on- and off-camera flash products with internal lithium ion batteries, providing all the benefits of an external battery pack. The Li-on line offers a range of high-power flash units and lighting accessories in easily transportable packages. Products include the Zoom Li-on speedlight Flash (available in manual, Canon TTL and Nikon TTL models), and the Zoom Li-on Flash Commander Transmitter and Receiver Set, all directed at bringing the best flash options to the studio or on location in an affordable package. Zoom Li-on Flash (Available in Manual, Canon TTL and Nikon TTL Models)
The Zoom Li-on speedlight flash is a miniature powerhouse that runs off an internal lithium ion battery. It is no bigger than a traditional speedlight, delivering all the benefits of an external battery pack without the messy cables. It has a full power recycle time of less than 1.5 seconds, allowing for near-instant continuous shooting. One battery charge holds up to 650 full power shots, and even more for lower-powered use.
The Zoom Li-on Flash is designed for sleek, easy use, with simple controls and a large, bright LCD screen. The flash head is incredibly versatile. It rotates 360 degrees and tilts over 90 degrees to work with any type of bounce or modifier, and the head zooms from 24mm to 105mm to ensure the necessary coverage without wasted spill. With numerous modes – manual, two optical slave modes and a stroboscopic mode, and remote power control using a Flashpoint Commander and Receiver, the Zoom Li-on Flash works on the fly for both on- and off-camera work.
In addition to TTL automatic output, the Zoom Li-on models for Canon or Nikon TTL offer all the extra features of proprietary TTL strobes, such as HSS, exposure compensation, exposure bracketing, automatic zooming and flash exposure lock. Additionally, they offer complete integration with proprietary TTL strobe IR remote control systems, and can be used to control or be controlled by Canon or Nikon flashes as a master or slave, as well as for group control.
The Zoom Li-on Flash comes with a li-ion battery pack, battery charger, mini stand, protective case and instruction manual. Zoom Li-on Flash Commander Transmitter and Receiver Set
The Commander Transmitter and Receiver Set is the perfect companion to the Zoom Li-on Flash, and is backwards-compatible with the Flashpoint Streaklight line. It allows remote power control from 150+ feet, allowing users to view and change flash output at any time. Other flash functions can also be adjusted remotely. With 16 channels and 16 groups, you can remotely control individual units or groups no matter how many units you use, and avoid interfering with other photographers.

An ideal entry-level DSLR for the creative photographer ready to take their storytelling to a new level, the D5500 sports an impressive arsenal of imaging technology, including a 24.2-megapixel CMOS sensor with no optical low-pass filter (OLPF) and a new 3.2-inch Vari-angle touch operation LCD display. All of this and more is packed into a new monocoque design that makes the camera one of Nikon’s lightest and most convenient-to-carry DSLR offerings. Nikon has also expanded its already impressive line of NIKKOR lenses with two new additions, the versatile AF-S DX NIKKOR 55-200mm f/4.5-5.6G ED VR II zoom lens for DX-format shooters and the FX-format AF-S NIKKOR 300mm f/4E PF ED VR, a lens with advanced Phase Fresnel optics for lightweight super-telephoto performance.
