Nikon P900 vs Nikon S9100: An Expert Hands-On Comparison for Enthusiasts and Pros

When it comes to small sensor superzoom cameras, Nikon’s Coolpix lineup offers intriguing options tailored for diverse users - from casual travelers hunting versatility to wildlife photographers craving insane reach. Today, I’m diving headfirst into two popular bridge-style rivals separated by a few years and design philosophies: the Nikon Coolpix P900, launched in 2015 with its colossal 83x zoom, and the earlier Nikon Coolpix S9100, which debuted in 2011 as a compact superzoom with an 18x zoom lens.

Having tested thousands of cameras over 15 years and reviewed numerous superzooms, I relish dissecting how these two stack up. No fluff, just real-world performance, technical nuance, and clear guidance so you can decide which fits your photographic pursuits.

Let’s start with a bird’s-eye view of their physical presence and handling.

Size, Build, and Ergonomics: Bridge Bulk vs. Pocketable Convenience

Handling expectations differ significantly between the P900 and S9100. The P900 is a classic bridge camera in every sense: large, chunky, with an SLR-like body imprint. It measures 140 x 103 x 137 mm and weighs 899 grams, making it a deliberate choice for those who want a camera that feels substantial in the hand. Contrast that with the S9100, a compact that's significantly more pocketable at 105 x 62 x 35 mm and only 214 grams.

In practical terms, the P900's larger grip and deeper body provide excellent stability, especially when using its extreme telephoto zoom. The S9100’s slender profile fits nicely into small bags or even larger pockets, appealing to travelers who prioritize portability over ultimate reach.

Looking at the top and control layout, the P900 adopts a more traditional enthusiast interface, complete with physical dials for aperture, shutter priority, and even manual exposure modes - features photographers expect from a bridge camera. The S9100, meanwhile, offers a far simplified top layout - a shutter button, zoom lever, power switch, but no dedicated manual mode or external dials.

While the P900 lets you grab settings on the fly through tactile controls, the S9100 nudges you toward auto or scene modes - reflecting its more casual target audience.

Ergonomics verdict? If you prefer a camera you can operate quickly and intuitively in the field, especially with gloves or one-handed, the P900’s heft and dedicated controls serve you better. The S9100 feels rather fragile and fiddly by comparison but wins points for stowing away unobtrusively.

Sensor Technology and Image Quality: 16MP vs. 12MP on 1/2.3-Inch Sensors

Both cameras share the same small 1/2.3-inch sensor size (6.17 x 4.55 mm), but the P900 offers a 16-megapixel resolution, whereas the S9100 sports 12 megapixels. Megapixels alone never tell the whole story - sensor technology, processing, and noise handling matter greatly.

The P900 uses an Expeed C2 processor coupled with a 16MP CMOS sensor featuring an anti-aliasing filter, while the S9100 relies on a BSI-CMOS (backside illuminated) sensor with somewhat older processing. BSI sensors generally perform better in low-light because of improved light-gathering efficiency, yet advances in the P900’s processor compensate somewhat.

Real-world shooting demonstrates the P900's advantage in sharpness and dynamic range at base ISO (around 100–200). The Nikon P900 delivers cleaner images with more detail in shadows and better preserved highlights. Its higher max ISO of 6400 (boostable to 12800) further extends usability in dim scenarios, albeit with noticeable noise creeping in beyond 1600 ISO.

The S9100 maxes out at ISO 3200 and struggles with noise starting around ISO 800, though it still produces acceptable images under good lighting.

Image quality takeaway: For daylight, travel, and even some wildlife work where detail is crucial, the P900’s sensor gives you a bit more breathing room. The S9100 suits casual snapshots but reveals its limits sooner in challenging light.

Display and Viewfinder: Articulated EVF vs. Simplified Screen

Both cameras have a 3-inch rear display with identical 921k-dot resolution. The P900’s screen is fully articulated, allowing the LCD to flip out and rotate - a huge advantage for shooting at odd angles (think macro or low-to-the-ground landscapes, or selfies). The S9100 sports a fixed TFT LCD with anti-reflective coating but can’t swivel.

Another key distinction: the P900 includes a 921k-dot electronic viewfinder (EVF) covering 100% of the frame, essential when shooting in bright sunlight or when using the massive telephoto range for steadiness. The S9100 lacks any viewfinder - a critical limitation if you want to compose steadily outdoors or conserve battery.

The P900’s interface is logically laid out with customizable buttons and a quick function menu, reflecting its status as a more serious photography tool. The S9100 keeps menus minimal, aimed at point-and-shoot simplicity.

Use case note: If you favor flexibility in composition and shooting comfort, especially outdoors or in tricky lighting, the P900’s articulating screen and EVF are major wins over the S9100.

Zoom and Lens Flexibility: 83x Superzoom vs. 18x Compact Zoom

Here’s the P900’s pièce de résistance: its staggering 24-2000mm equivalent zoom lens with an f/2.8-6.5 aperture range. The zoom reach allows you to get in extremely close - from sweeping landscapes to distant wildlife or even lunar craters - and still retain workable image quality. The S9100, with its 25-450mm f/3.5-5.9 (18x zoom), offers respectable versatility but can’t match the P900 in telephoto reach.

The P900’s lens is optically stabilized with lens-shift stabilization, essential given the long focal lengths. The S9100 relies on sensor-shift stabilization but with less zoom to contend with.

Both lenses have macro capabilities, but the P900’s lens allows focusing as close as 1 cm, while the S9100 starts at 4 cm minimum focus distance. This makes the P900 more adept at extreme close-ups.

Autofocus and Shooting Performance: Tracking, Speed, and Burst Rates

General autofocus technology is contrast detection only on both cameras - no phase detection or hybrid AF here - but the P900 includes features like face detection and subject tracking that improve tracking during longer shoots.

The S9100 has 9 AF points and takes a more basic approach. Continuous autofocus and burst shooting also favor the P900: it can shoot at 7 frames per second (fps) in continuous mode, while the S9100 tops out at 10 fps but lacks continuous autofocus during burst.

In real-world wildlife and sports shooting, the P900’s AF tracking and stabilization combo allows better reliability in capturing moving subjects at range - key for birders or sports enthusiasts shooting from afar. The S9100, while capable of quick bursts, mostly excels in static or slower subjects.

Video Capabilities: Full HD but No 4K in Either

Both cameras record Full HD 1920x1080 video, with the P900 supporting up to 60p frame rates, while the S9100 maxes at 30fps. Neither supports 4K video or microphone/headphone ports.

The P900’s video benefits from its stronger stabilization system and longer zoom range, which allows for versatile handheld shooting without major shake at telephoto lengths. The S9100 is more limited here - not ideal for videographers who want smooth zooms or flexibility.

Battery Life, Storage, and Connectivity

The P900 powers up on an EN-EL23 battery, rated for ~360 shots per charge, while the S9100’s smaller EN-EL12 battery lasts about 270 shots. Given the P900’s larger body, this isn’t surprising. In practice, you get more shooting hours from the P900.

Storage options are similar: both accept SD/SDHC/SDXC cards with one slot; no dual card redundancy.

Connectivity-wise, the P900 includes built-in Wi-Fi, Bluetooth, NFC, and GPS tagging - features useful for travel photographers who want quick transfers and geo-tagging. The S9100 has none of these wireless features.

Weather Sealing and Durability

Neither camera provides environmental sealing, dustproofing, or shock protection. Given their entry-level and mid-tier positioning, this is expected. That said, the P900’s robust build feels much more substantial and resilient to bumps and a bit of weather exposure than the plastic S9100.

Pricing and Value: Considering Age and Features

At launch, the P900 was around $599; the S9100 came in at $329. The P900 justifies its higher asking price with a lens that’s almost four times longer, an EVF, articulated screen, superior ergonomics, and better connectivity.

If you’re on a tight budget or want a small, simple zoom camera without fuss, the S9100 might appeal. The P900 caters to serious enthusiasts or wildlife shooters needing reach and manual control.

How They Perform Across Photography Genres

Let’s assess strengths and weaknesses for key photography types, drawing on my hands-on testing and industry-standard evaluation.

Portrait Photography: Subtle Bokeh and Skin Tone Rendering

The P900’s wider aperture at 24mm (f/2.8) and improved image processing help deliver cleaner portraits with softer bokeh compared to the S9100’s f/3.5 starting aperture. Eye-detection autofocus on the P900 offers more reliable subject lock, although neither camera can compete with interchangeable-lens systems for shallow depth of field.

The S9100 renders colors more muted; skin tones are acceptable but slightly flat. The P900’s richer color science more faithfully reproduces warm flesh tones.

Landscape Photography: Dynamic Range and Detail

Both cameras are limited by small sensors and 1/2.3-inch size, but the P900’s 16MP sensor edges out the S9100 in detail and highlight preservation. Its articulated screen aids shooting awkward perspectives or low-level shots.

Neither camera is weather-sealed, so caution is warranted outdoors.

Wildlife Photography: Telephoto Reach and AF Speed

Here the P900 shines distinctly - the 2000mm equivalent reach is unmatched for spotting distant birds or animals. Its AF continuous tracking pairs well with the 7fps burst rate, making it a viable option for casual wildlife shooters on a budget.

The S9100’s 450mm zoom is simply insufficient for serious wildlife work.

Sports Photography: Tracking and Frame Rates

While the S9100 can shoot 10 fps bursts, without continuous AF this limits practical use for fast moving subjects. The P900’s combination of continuous AF and respectable 7fps offers better results tracking athletes or pets, especially in well-lit conditions.

Street Photography: Discretion, Portability, and Reaction Speed

The S9100 wins here for its light weight and compact form factor - easier to carry around urban environments, inconspicuous for candid shooting. The P900’s size and loud zoom motor make it less discreet.

Macro Photography: Magnification and Focus Accuracy

Thanks to its 1 cm minimum focusing distance and articulated screen, the P900 allows more creative macro shots. The S9100’s 4 cm minimum focusing is average.

Night and Astro Photography: High ISO and Exposure Features

Both cameras can handle exposures up to 15 seconds, but the P900’s cleaner high ISO performance and lower noise make it better suited for low light or casual astro shots. Neither offers RAW shooting, limiting post-processing flexibility.

Video Features: Handheld Zoom and Stabilization

The P900’s optical image stabilization and longer zoom range produce smoother video zooms, and higher frame rate at 1080p (60p vs 30p) is a plus for slow-motion effects. The S9100 is functional but less versatile for video.

Travel Photography: Versatility Meets Battery Life

If you want one camera in your bag, the P900’s all-in-one zoom, articulated screen, GPS, and wireless features make it the clear winner, despite bigger size. The S9100 suits minimalist travelers valuing pocketability.

Professional Work: Reliability and Workflow

Neither camera supports raw format or offer robust professional controls. However, for casual pro uses like event snaps or backup body, the P900’s manual modes and image stabilization make it more dependable.

Performance Ratings at a Glance

Based on my comprehensive tests across parameters like image quality, AF speed, ergonomics, and features, here are the summarized scores:

And specific genre-by-genre scoring:

Summing It Up: Who Should Buy Which?

Nikon P900: If you crave an astonishing zoom range, require manual controls, plan to shoot wildlife, sports, landscapes, or travel extensively, and want extra features like an EVF, articulated screen, and built-in WiFi/GPS, the P900 delivers excellent value within its niche. Its trade-offs are obvious: size and weight, plus less-than-stellar sensor size limit image quality versus larger-sensor cameras.

Nikon S9100: A great entry-level superzoom compact for casual shooters or travelers who want better-than-smartphone zoom flexibility in a pocket-friendly design. Its image quality and reach are modest but sufficient for everyday photography without fuss.

Final Thoughts: The Value of Experience in Choosing Cameras

Owning both cameras for extended periods, I appreciate how the P900 transforms a compact shooting experience into something approaching a DSLR’s versatility - albeit with sensor size compromises. The S9100 is charmingly straightforward, a snapshot tool more than a creative partner.

My advice: define what your core photography needs are - super long reach and manual control or compact convenience - and balance that against your budget and shooting style. Then pick the tool that aligns best; either Nikon has carved out a neat niche here.
