Nikon’s passionate commitment to lens manufacturing, from painstaking design through the making of our own glass, delivers superior mechanical operation and unsurpassed imaging performance.

SILENT WAVE MOTOR
The Nikon Silent Wave Motor uses ultrasonic traveling waves, converted to rotational energy, to focus AF-S NIKKOR lenses. The ultrasonic waves, moving in a spiral pattern inside the lens barrel, drive the cylindrical motor that moves the lens elements. This powerful and responsive high-torque motor system provides instant startup, high-speed autofocusing and incredible accuracy.

The Silent Wave Motor represents a significant advance in AF lens technology. Conventional autofocus lenses are driven by a motor in the camera linked to the lens by a gear system. Using inaudible ultrasonic frequencies—in effect, ultrasonic vibrations—rather than a gear system results in incredibly smooth, silent and precise AF operation.

ED GLASS
Nikon’s Extra-low Dispersion (ED) and Super ED glass help correct chromatic aberrations, or optical color defects, caused when different light wavelengths do not converge at the same point after passing through optical glass. Calcium fluorite crystals were once used to correct this problem in telephoto lenses, but the substance cracked easily and was sensitive to temperature changes. So Nikon created ED glass, which offers all the benefits, but none of the drawbacks of calcium fluorite-based glass. ED glass is now an essential element in NIKKOR’s telephoto lenses, helping deliver stunning sharpness and contrast, even at maximum aperture.

G-TYPE LENSES
G-type NIKKOR lenses have no aperture control ring and are intended for use on Nikon D-SLRs that allow the lens aperture to be adjusted via the camera’s command dial.

In addition, like D-type NIKKORS, G-type optics relay subject-to-camera distance information to Nikon digital SLRs. The information is used to help determine ambient and flash exposure.

VIBRATION REDUCTION
Vibration Reduction (VR) is an image stabilization technology that minimizes blur caused by camera shake. Using a VR NIKKOR lens can result in sharp images in low light, under windy conditions or when using a physically large NIKKOR lens, at up to four stops slower (with a VR II lens) than a non-VR lens.

Nikon VR originates in the lens, not in the image sensor, which means that algorithms optimized to an individual lens are applied. Another advantage of lens-based VR is that a separate algorithm confirms the stabilization effect when you press the shutter release button halfway, giving you the freedom to compose your image more easily. The system can also detect the use of a tripod, recognize panning?an instance in which you wouldn’t want the lens to compensate for movement?and address the specific shake caused by the ongoing vibration patterns produced when shooting from a moving vehicle.

Nikon VR lenses use two angular velocity sensors, one that detects vertical movement (pitch), the other, horizontal movement (yaw), with diagonal motion handled by both sensors working together. The sensors send angular velocity data to a microcomputer in the lens, which determines how much compensation is needed to offset the camera’s shake and sends that information to a duo of voice coil motors that move selected lens elements to compensate for the detected motion.

What does this mean in practical terms? A rock-steady camera is essential to critical image sharpness, and Nikon’s exclusive Vibration Reduction technology offers the perfect solution for reducing the image blur caused by camera shake. It provides you with up to four stops of “hand-holdability,” delivering dramatically sharper images in a wide range of conditions.
Not all anti-shake technologies are the same. The in-camera anti-shake technology used by some manufacturers relies on a process that actually shifts the image sensor, and its performance benefit is generally agreed to be limited to about one-and-one-half to two stops. For Nikon photographers, an additional two stops of VR performance capability can easily be the difference between a blurry picture and a beautiful sharp one.

But the benefits of Nikon VR aren’t limited to shutter speeds. Consider shooting on an overcast day at a medium ISO where greater depth-of-field might be desirable. Because using a Nikon VR lens means you’ve got up to four extra stops available, you can choose an aperture of f/8 rather than f/2?and there’s your depth-of-field. And having up to four stops to work with also offers the possibility of shooting at lower ISO settings, thus maximizing image quality.

NIKKOR DX
Nikon digital SLRs have either an FX or a DX sensor. The FX sensor, measuring 24×36mm, is roughly equivalent to the size of the 35mm film frame. The DX sensor is smaller, measuring 15.8×23.6mm.

DX-NIKKOR lenses are engineered and optimized for use on Nikon DX-format D-SLRs and are designed to cover the smaller image area of the DX sensor. When a DX lens is mounted on an FX-format Nikon D-SLR, the camera’s DX-Crop Mode is automatically engaged, introducing a 1.5x magnification (cropping) factor.

INTERNAL FOCUSING
Internal focusing refers to a NIKKOR lens in which the movement of the optical elements takes place within the lens barrel and does not involve the movement of the barrel. Thus, IF NIKKORS do not change in size during AF operation, allowing for compact, lightweight lenses capable of closer focusing distances.

Super Integrated Coating and Nano Crystal Coat
Nikon Super Integrated Coating is Nikon’s term for its multilayer coating of the optical elements in NIKKOR lenses. This multilayer coating helps reduce lens flare (the appearance on the image of the distinctive shape of the lens diaphragm, caused when non-image-forming light enters the lens and hits the camera’s sensor) and ghosting (bright spots of reflected light that appear on the image, the result of the camera being pointed at a bright light source). Nikon’s Super Integrated Coating is especially effective for lenses with a large number of elements, and the multilayer coating process is tailored to the design of each particular NIKKOR. The number of coatings applied to each lens element is carefully calculated to match the lens type and glass used, and also to assure uniform color balance.

Nano Crystal Coat is an antireflective coating that virtually eliminates internal lens element reflections across a wide range of wavelengths, and is particularly effective in reducing ghost and flare peculiar to ultra-wide-angle lenses. Nano Crystal Coat employs multiple layers of Nikon’s extra-low refractive index coating, which features ultra-fine crystallized particles of nanometer size.

Camera, lenses, flash, dan accessories lainnya yang sudah anda miliki, sudah selayaknya diperlihara dengan baik dan benar. Karena biaya yang sudah anda keluarkan itu, sudah pasti tidak sedikit. Sering sekali hal mengejutkan terjadi pada banyak orang bahwa ada saat tertentu dimana peralatan photography anda mengalamai kerusakan, sedang garansi pembelian sudah berakhir, dan sudah bisa dibayangkan, harga perbaikannya bisa sama harganya dengan beli baru.

Jika anda hendak bepergian travelling atau hunting photo, simpanlah semua perlengkapan fotografi anda di dalam tas khusus kamera. Di tas khusus ini ada ruang-ruang tertentu untuk masing-masing peralatan. bilik-bilik ini juga bisa dirubah-rubah ukurannya, disesuaikan dengan ruang yang diperlukan oleh peralatan anda. Benefit lain dari model tas seperti ini adalah, anda bisa langsung melihat apakah semua perlengkapan yang anda butuhkan sudah ada. Merek tas semacam ini yang disukai banyak orang dan saya rekomendasikan adalah lowepro. cek jenisnya di www.lowepro.com

Jika di depan lensa anda ada drat untuk menempatkan filter, sebaiknya setiap kamera anda ditambahkan filter UV. di samping untuk mereduksi sinar ultra violet yang tertangkap kamera, filter ini juga bagus untuk proteksi permukaan depan dari lensa. bayangkan kalau kaca depannya tergores, berapa biaya yang harus dikeluarkan. kalau filter tergores, anda cuma perlu ganti filter baru yang harganya relatif murah.

Saya juga mau menggarisbawahi pentingnya penggunaan hood di setiap lensa anda (kalau memungkinkan. artinya ada drat untuk hood). Di samping untuk reduksi blare atau pantulan sinar lain yang mungkin masuk ke lensa, hood ini juga melindungi permukaan lensa dari percikan air (entah gerimis atau air lainnya), bahkan hentakan atau persinggungan lainnya.

Jika lensa atau filter kotor oleh debu, hal pertama yang perlu dilakukan adalah dengan meniup (blow away) debu-debu itu. Ini bisa dilakukan dengan photographic blower brush (lihat gambar di samping) yang bisa didapatkan di banyak toko fotografi. beberapa ahli tidak menyarankan penggunaan blower bertekanan tingi (bentuknya seperti kaleng obat nyamuk spray dengan pipa tiup perpanjangan).

Untuk menghapus grease atau bekas sidik jari (finger marks), gunakan disposable lens tissue. jika susah sekali hilangnya, bisa ditambahkan cleaning fluid (biasanya dijual satu paket dengan tissue dan blower brush).

Jangan pernah gunakan kain biasa apalagi kain yang sudah usang untuk membersihkan permukaan lensa. karena dia dapat menyebabkan/menambahkan terjadinya efek abbrasive di permukaan lensa, bahkan meninggalkan bekas goresan.

Jika sedang tidak menggunakan semua peralatan photography anda untuk saat yang agak lama, selalu lepaskan semua batteries dari body camera dan flashes. Ini pencegahan terhadap kebocoran (leakage), yang jika terjadi, dapat menyebabkan karat ekstensif di dalam sirkuit listrik kamera. hal yang sama juga bisa terjadi di flash, dan exposure meter.

Jangan pernah menyimpan kamera di lemari pakain untuk waktu lama. lagi-lagi pengalaman sendiri: sudah menelan satu korban lensa kit, disimpan selama dua bulan tidak pernah dipakai, lensa langsung jamuran. sayang sekali memang.

Simpanlah semua peralatan anda di dry box atau dry cabinet. kedua alat ini dapat menjaga tingkat kelembaban (humiditas) di level yang sangat aman. Jika peralatan anda sudah mulai berkembang biak (baca: tambah banyak), penggunaan dry cabinet sangat dianjurkan. penjagaan terhadap tingkat humiditasnya dilakukan secara elektronis. sementara dry box, punya peluang besar untuk kebocoran – pengalaman saya. ada 2 pilihan favorit: 40 liter atau 80 liter.

nama lengkapnya AF-S VR Zoom-Nikkor 70-300mm f/4.5-5.6G IF-ED.

Nikon Vibration Reduction System
SLR Advanced Nikon engineering has given rise to a compact lightweight lens design that offers outstanding optical performance and excellent handling characteristics. The new Nikon Vibration Reduction (VRII) system enables users to take substantially sharper handheld pictures at slower shutter speeds. With the new VRII system, users can take sharp pictures at shutter speeds approximately 4 stops slower* than would otherwise be possible. For VR shooting, users can select two VR modes to match shooting conditions. Normal Mode primarily reduces camera shake in handheld shooting, detecting panning automatically. Active Mode can compensate for vibration when shooting from, for example, a moving vehicle.

Nikon 70-300mm f/4.5-5.6G IF-ED Nikkor lens
The AF-S VR Zoom-Nikkor 70-300mm f/4.5-5.6G IF-ED also offers proven Nikon features and technologies such as the SWM, which offers fast and precise autofocusing with super-quiet operation, and two ED glass elements that provide higher resolution and high-contrast images. Together with the AF-S DX 18-70mm f/3.5-4.5G IF-ED lens, it gives Nikon digital SLR owners a focal-length range from a wide 18mm to super telephoto 300mm (the picture angle is equivalent to 27mm to 450mm of 35mm format).
