300mm f/4E AF-S PF ED VR

The Phase Fresnel Revolution in Telephoto Design

The Nikon AF-S FX Nikkor 300mm f/4E PF ED Vibration Reduction Lens represents a significant departure from traditional refractive optical design. It is the first lens in the Nikkor lineup to utilize a Phase Fresnel (PF) lens element. This technology, based on the principles of diffraction, allows a single, thin lens element to perform the chromatic aberration correction that would typically require multiple heavy glass elements. By utilizing a PF element in conjunction with a standard Extra-low Dispersion (ED) glass element, Nikon reduced the overall length of the lens to 147.5mm and the weight to approximately 755g. For context, this is nearly 50% lighter and 30% shorter than its predecessor, the AF-S Nikkor 300mm f/4D IF-ED, making it one of the most portable 300mm prime lenses ever produced for the F-mount system.

Positioned as a professional-grade "Gold Ring" lens, it is designed for photographers who require the reach of a 300mm focal length but operate in environments where heavy tripods or monopods are impractical. The optical formula consists of 16 elements in 10 groups. The inclusion of the Phase Fresnel element specifically targets the correction of chromatic aberration (color fringing) by utilizing the opposite dispersion characteristics of refractive and diffractive elements. When light passes through the PF element, it is bent in a way that compensates for the dispersion of the other glass elements, resulting in a highly corrected image with minimal weight. This lens is built for the FX-format (full-frame) sensor but is fully compatible with DX-format (APS-C) bodies, where it provides an effective focal length of 450mm.

Optical Technologies and Image Quality

The image quality of the Nikon AF-S FX Nikkor 300mm f/4E PF ED Vibration Reduction Lens is defined by its ability to maintain high contrast and resolution even at its maximum aperture of f/4. The primary technological driver here is the Nano Crystal Coat (N), an anti-reflective coating that uses nano-sized crystal particles to virtually eliminate internal lens element reflections across a wide range of wavelengths. This is particularly effective in telephoto lenses where stray light can often cause ghosting and flare when shooting toward a light source. Additionally, the lens features a Fluorine coat on the front element, which actively repels water, dust, and grease, making it easier to clean without damaging the glass surface.

The 9-blade rounded diaphragm creates a natural, circular bokeh, which is critical for a 300mm lens often used for subject isolation. While the f/4 aperture is one stop slower than the f/2.8 variants, the optical precision of the ED glass ensures that there is very little "purple fringing" on high-contrast edges, such as a bird's feathers against a bright sky. One unique characteristic of the Phase Fresnel element is the potential for ring-shaped flare when a bright light source is located directly within the frame. Nikon addresses this through specialized "PF Flare Control" software in Nikon Capture NX-D, though the physical coatings on the lens are designed to minimize this occurrence in standard shooting conditions.

Autofocus Precision and Vibration Reduction

Handling this lens on a shoot is characterized by its internal focusing (IF) system and the Silent Wave Motor (SWM). The SWM uses ultrasonic vibrations to drive the focus group, providing fast, near-silent autofocus that allows for full-time manual focus override (M/A mode). Because the lens is so light, the autofocus motor can move the smaller internal elements with extreme speed, making it highly responsive for tracking fast-moving subjects. The lens has a minimum focus distance of 1.4 meters (4.6 feet), providing a maximum reproduction ratio of 0.24x, which allows for close-up telephoto work on smaller subjects like large insects or flowers.

The Vibration Reduction (VR) system in this lens provides up to 4.5 stops of compensation, according to CIPA standards. This is a critical feature given that the lens is designed primarily for handheld use. It features two distinct VR modes:

• Normal Mode: Designed for stationary subjects, it compensates for camera shake in all directions.
• Sport Mode: Specifically engineered for tracking erratic, fast-moving subjects. In Sport Mode, the viewfinder image remains stable during high-speed panning and bursts, and the camera's frame rate and shutter lag are not compromised, which is a common issue with standard VR modes during continuous shooting.

Video Performance and Limitations

While primarily an optics-first lens for stills, the Nikon AF-S FX Nikkor 300mm f/4E PF ED Vibration Reduction Lens offers specific advantages for videographers. The electromagnetic diaphragm is the most significant benefit here; it allows for smoother aperture transitions when changing depth of field or exposure mid-shot, avoiding the "stepping" effect seen with mechanical levers. On modern Nikon Z-series bodies via the FTZ adapter, or on high-end DSLRs like the D850, this allows for silent and precise iris control.

The 300mm focal length on a full-frame sensor provides a narrow 8° 10' angle of view, which is excellent for capturing distant details in a documentary setting. However, for video, the lightweight nature of the lens can be a double-edged sword. While it is easy to mount on a gimbal, the lack of physical mass means that micro-jitters are more easily transmitted to the sensor than they would be with a heavier 300mm f/2.8 lens. The VR system is effective at dampening these jitters, but for professional cinema work, a solid tripod or a high-payload gimbal is still recommended. The focus ring is well-damped but has a relatively short throw, which can make fine manual focus pulls challenging without a follow-focus system. There is no "Power Zoom" or "Silent Aperture" ring, as this remains a traditional F-mount mechanical design.

On the Shoot: Indian Photography Scenarios

In a practical shooting environment in India, this lens solves specific logistical problems. Consider a wildlife safari in Ranthambore National Park. Shooting from an open-top Gypsy involves constant vibration and limited space. A traditional 300mm f/2.8 or a 200-400mm zoom is heavy and difficult to maneuver when a tiger suddenly moves through the brush. The 755g weight of the 300mm f/4E PF allows a photographer to handhold the camera for hours without fatigue, reacting instantly to movement. The VR system compensates for the engine vibrations of the vehicle, and the f/4 aperture provides enough light gathering for the "golden hour" sessions at dawn and dusk.

During a high-action sports event, such as a T20 cricket match at the Wankhede Stadium, the lens excels in the "Sport VR" mode. A photographer positioned in the stands or at the boundary can track a fielder running for a catch without the viewfinder image jumping. The 300mm reach is sufficient to cover the pitch from the boundary, and if paired with a DX-format body like the D500, the 450mm equivalent reach allows for tight shots of the batsman's footwork. The electromagnetic diaphragm ensures that every frame in a 10fps or 12fps burst is exposed identically, even as the stadium floodlights cycle.

For a travel and documentary shoot in the Western Ghats during the monsoon, the portability and weather sealing are paramount. Trekking through dense foliage to photograph endemic bird species requires gear that doesn't weigh down the kit bag. The 300mm f/4E PF fits into a standard shoulder bag, unlike other 300mm primes that require dedicated backpacks. The Fluorine coating is particularly useful here, as it allows the photographer to quickly wipe away mist or raindrops from the front element without leaving streaks that would degrade the image quality of a rare bird sighting.

Compatibility and Pairing Options

The Nikon AF-S FX Nikkor 300mm f/4E PF ED Vibration Reduction Lens uses the Nikon F-mount. It is fully compatible with all Nikon FX and DX digital SLR cameras. However, because it uses an electromagnetic diaphragm (E-type), it has limited compatibility with older film cameras and early digital bodies. It is fully compatible with the D5, D4 series, D3 series, D850, D810, D800 series, D750, D700, D610, D600, D500, D300 series, D7500, D7200, D7100, D7000, D5600, D5500, D5300, D5200, D5100, D5000, D3400, D3300, D3200, and D3100. It will not work on the D2 series, D1 series, D200, D100, D90, D80, D70 series, D60, D50, D40 series, or film cameras, as the aperture will remain fixed at its smallest setting.

For users of the Nikon Z-mount mirrorless system (Z9, Z8, Z7II, Z6II, etc.), this lens performs exceptionally well when paired with the FTZ or FTZ II Mount Adapter. It retains full autofocus speed and VR functionality. This lens is also highly compatible with Nikon’s TC-E series teleconverters:

• TC-14E III: Results in a 420mm f/5.6 lens with full AF capability on most modern bodies.
• TC-17E II: Results in a 510mm f/6.7 lens; AF is possible on cameras that support f/8 autofocus (like the D850 or D5).
• TC-20E III: Results in a 600mm f/8 lens; AF is maintained on f/8-compatible sensor points.

Who Should Choose Something Else

While the Nikon AF-S FX Nikkor 300mm f/4E PF ED Vibration Reduction Lens is a technological marvel, it is not the universal choice for every telephoto need. Photographers who primarily shoot in extremely low light, such as indoor basketball or night-time wildlife, may find the f/4 maximum aperture limiting. In these cases, the AF-S Nikkor 300mm f/2.8G ED VR II is the superior choice, offering a full stop more light and even shallower depth of field, though at the cost of nearly 2.2kg of additional weight.

For those who require focal length flexibility, a zoom lens like the AF-S Nikkor 200-500mm f/5.6E ED VR or the AF-S Nikkor 80-400mm f/4.5-5.6G ED VR might be more appropriate. While these zooms are significantly heavier and larger, they allow the photographer to reframe without moving, which is often impossible in a stadium or a safari vehicle. Finally, if the budget is the primary concern and weight is not an issue, the older AF-S Nikkor 300mm f/4D IF-ED provides similar reach and excellent optics for a lower investment, though it lacks Vibration Reduction and the compact PF construction, making it much harder to use handheld at slower shutter speeds.

The Nikon 300mm f/4 AF-S PF ED VR is a game changing lens!

Just 147.5mm long and weighing only 755g, it is the world's lightest 300mm full-frame AF lens (as of Mar 2015).

The secret to its remarkable size? A Nikon-designed Phase Fresnel (PF) lens element, a first for the NIKKOR DSLR lens lineup. But handling isn't the only advantage; the PF element also performs brilliantly—achieve new levels of sharpness and clarity with virtually no chromatic aberration or ghosting. Whether you shoot fashion, portraits, nature, wildlife, sports, action or today's big stories, the AF-S NIKKOR 300mm f/4E PF ED VR will help you capture stunning images.
