Nikon, nuovi 300mm f2,8 VRII e TC-20EIII - [BLOG]
AF-S NIKKOR 300mm f/2.8G ED VR II, hood HK-30 - Click per ingrandire
Anche se molti pensano che sarebbe ora di aggiornare l'oramai vetusto (ma sempre valido) 85mm f1,4 o di introdurre nuove iterazioni del leggendario 28mm f1,4 e magari pensare pure ad un 35mm pari apertura, i due prodotti appena presentati non lasciano certo con l'amaro in bocca.
Si tratta della rinnovata versione del 300mm AF-S VR, totalmente in magnesio, tropicalizzato, con trattamento Nano Crystal Coat, elementi ED e adesso dotato di sistema di stabilizzazione di ultima generazione.
AF-S TC-20E III - Click per ingrandire
Il il TC-20EIII rinnova la tradizione Nikon di offrire una nutrita linea di convertitori di focale dalle elevate prestazioni e non è un caso se l'annuncio è stato fatto in concomitanza con il lancio del 300mm.
Abbinato con questo obiettivo, infatti, il TC-20EIII garantisce una focale utile di 600mm su un corpo full-frame ma, al contempo, una soluzione relativamente compatta rispetto per esempio al mastodontico 600/4. Il TC di terza generazione naturalmente supporta in pieno il sistema VR, aggiungendo, per la prima volta nella storia dei moltiplicatori di focale Nikon, un elemento asferico nella formula ottica. In questo modo, coma e aberrazioni cromatiche dovrebbero, nelle intenzioni del produttore, essere tenute a bada fino ai bordi estremi del fotogramma.
E' lecito pensare a questo punto che i prossimi obiettivi tele e zoom-tele ad essere aggiornati potrebbero essere il 200mm F2 VR ed il 200-400 F4 VR anche se l'urgenza maggiormente avvertita dagli utenti è quella di avere un 80-400 ed un 300/4 finalmente rinnovati.
Disponibilità, negli States, per entrambi da Gennaio 2010 a prezzi di 5,899.95 Dollari per il 300mm e 499,95 Dollari per il tele converter.

Press Release ufficiale (lingua inglese)
The New AF-S 300mm f/2.8 Lens and TC-20E III Teleconverter Focus on Super Telephoto
MELVILLE, N.Y. (Dec. 9, 2009) - Nikon Inc. today announced two new NIKKOR optics that deliver the pinnacle of image quality for professional photographers who demand super telephoto capabilities. The new, fast aperture AF-S NIKKOR 300mm f/2.8G ED VR II super telephoto lens and AF-S Teleconverter TC-20E III deliver images with stunning edge-to-edge sharpness and clarity throughout the frame. Continued refinements and new technologies such as Vibration Reduction (VR) II and optimized autofocus (AF) modes in the lens enhance functionality and improve performance for discerning FX and DX-format digital SLR photographers.
"The latest edition of the NIKKOR 300mm f/2.8 lens advances one of the most popular fast-aperture focal lengths for sports, nature and wildlife photography, demonstrating Nikon's commitment to professional photographers through the continued development of the optical fidelity and sharpness for which NIKKOR lenses are famous," said Edward Fasano, general manager for marketing, SLR Systems Products at Nikon Inc. "Offering compatibility with a wide range of NIKKOR optics, including the new 300mm f/2.8, the TC-20E III teleconverter enables photographers to greatly extend the versatility of a variety of zoom and telephoto lenses they carry."
Whether photographing nature in the wild or the battles at a line of scrimmage, the 300mm f/2.8 is an essential tool for photographers who require the highest level of image quality for publication and printing. This 300mm lens effectively leverages a host of Nikon core technologies, including Nikon VR II image stabilization, specifically engineered for each lens design for maximum performance. VR II instills confidence by counteracting image blur introduced by camera shake and telephoto magnification, allowing users to shoot up to four shutter speed stops* slower than otherwise possible, overcoming many of the challenges of handheld shooting. If tripod shooting is preferred, the Tripod Detection Mode will detect and compensate for tripod-specific vibrations.
This professional lens is constructed of die-cast magnesium for maximum durability and is strategically sealed to resist dust and moisture, with protective Meniscus glass to safeguard the lens' front element. The optical formula features three Extra-low Dispersion (ED) glass elements for superior sharpness, color and image quality, while minimizing chromatic aberration. Additionally, an aspherical element is used to promote image integrity throughout the frame, suppress coma and minimize distortion. The lens also features Nikon's exclusive Silent Wave Motor (SWM) technology which enables high-speed autofocus performance with exceptional accuracy and powerful, super-quiet operation. Nikon's exclusive Nano Crystal Coat prevents instances of ghosting and flare for even greater image clarity.
The AF-S 300mm f/2.8 lens features a host of professional focusing features that further enhance functionality. Photographers can now select from three focus modes to match shooting conditions, including manual mode (M) and autofocus with manual priority (M/A) mode, and the new A/M mode. The A/M mode enhances AF control with fast, secure switching from automatic and manual focus to adapt to personal shooting preference and techniques. Additionally, users can also activate the AF Recall Mode at the press of a button that allows for instant return to a predetermined point of focus to capture anticipated shots confidently.
Nikon's professional grade teleconverters, including the new AF-S TC-20E III are ideal companions to the new NIKKOR 300mm f/2.8 and other select lenses to create an affordable and portable gateway to extended telephoto photography. The new TC-20E III effectively doubles the focal length of select lenses, and is the world's first teleconverter to feature an aspherical element to virtually eliminate coma and other aberrations even at wide apertures.
Price and Availability
The AF-S DX NIKKOR 300mm f/2.8G ED VR II lens is scheduled to be available at Nikon authorized dealers with an estimated selling price of $5,899.95. The Nikon AF-S Teleconverter TC-20E III will be available for estimated selling price of $499.95**. Availability of both products is scheduled to begin in January, 2010.
