The pursuit of wildlife photography is a relentless balancing act between the reach required to capture elusive subjects and the practical reality of carrying the necessary gear. For decades, achieving those intimate, frame-filling shots meant relying on enormous, spine-compressing super-telephoto lenses, making the term “wildlife lens” synonymous with heavy tripods and travel headaches. However, as an amateur who has spent the last two years shooting with the Nikon Z 9 paired with the compact NIKKOR PF lenses—specifically the Nikon 500mm f5.6 PF (my go-to for handholding) and the Nikon 800mm 6.3 PF (usually on a monopod)—my entire photographic approach has been fundamentally transformed. This new breed of optics has been a true game-changer, and this article will provide fellow enthusiasts with a hands-on explanation of why this camera and lens combination has become invaluable for both my travel style and my workflow in the field.
Switching to the Nikon Z9 has made a dramatic difference in how I approach wildlife photography. This camera captures fast action, offers an incredible autofocus system, and its high-resolution sensor lets me crop my images without losing quality—a huge asset when birds or animals just won’t come close enough.
The Nikon Z9 offers several significant advantages for wildlife photography, making it one of the most advanced and reliable cameras available for this genre. Its powerful autofocus engine reliably detects and tracks animals—especially birds in flight or mammals moving through complex environments—ensuring consistently sharp images in action-packed moments. The camera’s 45.7-megapixel sensor delivers high-resolution files, providing flexibility to crop images without sacrificing detail, and the 20 frames-per-second shooting rate means photographers can capture split-second behaviour and motion with ease. Additional features such as blackout-free viewfinder, silent electronic shutter operation, deep buffer for long bursts, and settings recall add efficiency and comfort, making the Z9 well-suited for dynamic wildlife scenarios and challenging light conditions. Overall, these capabilities help wildlife photographers maximise opportunities in the field, yielding excellent keeper rates and enabling creative freedom during fast-moving or unpredictable encounters.
The real transformation, however, came when I paired my Z9 with Nikon’s innovative Phase Fresnel (PF) telephoto lenses, which are much lighter than any traditional lens at this focal length. Suddenly, I was able to walk further, react faster, and shoot longer without fatigue.
Understanding the Revolution: What is a PF Lens?
The secret sauce behind the featherlight nature of these super-teles is the adoption of Phase Fresnel (PF) lens elements. If you’ve ever wondered how an 800mm lens can be half the weight and dramatically shorter than its predecessor, the answer lies in the physics of light diffraction.
In a conventional (refractive) lens, the optical path requires numerous large, heavy glass elements—often Extra-low Dispersion (ED) or Fluorite elements—to correct for chromatic aberration (colour fringing). This happens because different wavelengths (colours) of light bend at different angles when passing through glass, causing them to focus at slightly different points.
A Phase Fresnel element, however, is a thin, moulded lens with a series of microscopic, concentric ridges, much like a lighthouse Fresnel lens. It works using the phenomenon of diffraction, where light waves are essentially steered. The critical innovation is that the PF element introduces chromatic dispersion in the reverse order of a conventional refractive lens.
By combining one PF element with standard refractive elements, this counteracting effect allows for superior chromatic aberration correction with significantly fewer, smaller, and lighter glass components. The result? A compact, lightweight, and supremely sharp lens that completely upends the traditional size-to-focal-length ratio.
The NIKKOR Z 800mm f/6.3 PF VR S, for instance, weighs a mere 2385 g(5.2lbs), making it close to half the weight of the previous 800mm f/5.6 F-mount monster. The F-mount NIKKOR 500mm f/5.6 PF, which I pair with the Z 9 via the FTZ II adapter, is even more astonishingly light at only 1460g (3.2lbs). This reduction in mass is the key to my newfound freedom.
The Nikon 500mm PF: Lightweight Freedom for Handheld Shooting
- Specs: 500mm focal length, f/5.6 max aperture, weighs just over 3 lbs (1.46kg), weather-resistant, 9-blade diaphragm for beautiful background blur.
- Experience: Unlike my old heavy telephoto lens, I can carry the 500mm PF on a Cotten Carrier affixed to my chest for hours, explore trails, wetlands, and forests, and actually handhold it for fast bird and mammal sightings—no tripod required.
- Mobility: When trying to find that elusive songbird deep in thick cover or track moving wildlife like deer or foxes, this lens never slows me down. Its size is similar to a small zoom lens, so I’m much less tired at the end of the day.
- Image Quality: The sharpness and contrast are outstanding even wide open, and VR (vibration reduction) is effective for steady shots handheld. Coupled with the Z9’s snappy autofocus and deep buffer, I can chase birds through the underbrush or react to sudden moments—like raptors diving or woodpeckers launching from a tree—without fumbling with gear.
The Nikon 800mm PF Z: Specialized Reach with Surprising Portability
- Specs: 800mm focal length, f/6.3 max aperture, weighs around 5.3 lbs (2.4kg), advanced VR, Z-mount optics for Z9, robust build.
- Monopod Use: When I know I’ll be working at longer distances—waterbirds across large marshes, shy birds in open fields, or mammals on distant hills—the 800mm PF Z unlocks scenes that were previously impossible for me to photograph. I mostly use a monopod for stabilisation, but the lens isn’t so heavy that I couldn’t handhold it for short bursts if needed.
- Mobility: For a lens at this focal length, it’s honestly portable. I’ve brought it on hikes and nature reserves, packed it for travel, and handled it without the stress of old super-telephotos. It fits in a regular camera backpack, and on the monopod, I can quickly reposition to frame wildlife across habitats.
- Image Quality: Stunning detail and beautiful background separation—even wide open. With the Z9, tracking small, distant subjects has become much more reliable.
Overcoming the Aperture Tradeoff
The tradeoff for this incredible size and weight reduction is the maximum aperture: f/5.6 and f/6.3, respectively. In the world of super-teles, where f/2.8 or f/4 were the kings, this is a clear reduction in light-gathering capability. This means that in low-light situations—dusk, dawn, or deep forest cover—we face a choice: sacrifice shutter speed or increase ISO. This is where the technological advancements of the Nikon Z 9 become the perfect counterweight.
Harnessing ISO
The Z 9’s stacked CMOS sensor and cutting-edge processing are designed to manage noise at higher ISO settings far better than the previous generation of cameras. Where I might have cringed at ISO3200 on an older DSLR, I now routinely push the Z 9 to ISO6400 or even 8000 when necessary to maintain a fast shutter speed (e.g., 1/1600 for fast-moving subjects like birds-in-flight).
Furthermore, with the power of modern post-processing software—especially tools like DxO PureRAW or Topaz Photo AI—the noise from these higher ISO settings is remarkably well managed. The result is a clean, detailed image that would have been impossible without the f/6.3 lens’s portability getting me to the location in the first place.
Taking advantage of advanced VR
As mentioned before, the combination of the Z 9’s IBIS and the lens’s optical VR (Synchro VR) allows for stability gains of 5 to 6 stops. For static or slowly moving subjects, this incredible stability allows us to confidently use slower shutter speeds (e.g., 1/80s for the 800mm, bringing the ISO down significantly and maximising dynamic range and image quality. This is a deliberate choice: use slower speeds for still subjects, and increase ISO for action. The versatility of the system lets us make that choice easily.
Advice for Fellow Enthusiasts
- If you haven’t used a PF lens yet, the difference in weight and mobility is really a game-changer. You don’t need pro-level strength or a huge budget—these lenses are easier to handle and travel with.
- The Z9’s autofocus locks onto birds and mammals quickly, and the high-resolution sensor gives lots of cropping flexibility when needed.
- Don’t be afraid to use the 500mm PF handheld even for action—it’s made for fast work in the field. Use the 800mm PF Z with a monopod for distance; both let you avoid the frustration and fatigue of older, heavier systems.
- For beginners, the extra reach gives much more creative freedom (I can get portraits of birds or detailed mammal shots I only dreamed of before). For experienced shooters, the portability lets you maximise time in the field without compromise.
Travel Advantages
Travelling with super-telephoto gear has always been a nightmare. The large f/4 and f/2.8 lenses often demanded their own dedicated, cumbersome carry-on roller, consuming all valuable space and adding hundreds to thousands of dollars in excess baggage fees for international flights.
The physical dimensions of the PF lenses are a travel photographer’s dream.
- The 500 mm f/5.6 PF is roughly the size of a conventional $70-200mm f/2.8. It fits easily in a standard messenger or smaller backpack, nestled beside the Z 9.
- The 800mm f/6.3 PF, while longer, still manages to fit diagonally into a medium-sized travel backpack. The key is its narrow diameter and relatively short overall length, 385mm/ 15.2in, making it manageable to pack alongside other gear.
My entire working kit—the Z 9, the 500mm PF, the 800mm PF, a wide-angle zoom, and a standard zoom—now fits into a single, discreet carry-on backpack. This not only saves on cost but, crucially, on stress. No more checking invaluable gear or having a lens refused as a carry-on by an overzealous gate agent. The photographer is free to focus on the mission, not the logistics.
Final Thoughts
As an amateur, these gear choices have let me photograph wildlife in new ways and actually enjoy longer excursions, more action, and less fatigue. If you’re exploring wildlife photography and want flexible, mobile, high-performance gear for birds or mammals, the Z9 with the Nikon 500mm PF (handheld) and Nikon 800mm PF Z (monopod) setup is hard to beat. It’s freed me up to explore, react fast, and get images that I previously thought were only achievable by pros with huge, heavy lenses.
