Nikon P100 vs Sony HX99: A Hands-On Comparison of Two Small-Sensor Superzooms

When venturing into the realm of small-sensor superzoom cameras, photographers often have to balance zoom reach, image quality, portability, and modern features. As someone who has spent over 15 years testing hundreds of cameras - including numerous bridge and compact superzooms - I find this category fascinating for travel and everyday shooting. Today, I’m diving deep into two contenders that, at first glance, might seem similar but reveal significant differences when you look under the hood: the Nikon Coolpix P100 (2010) and the Sony Cyber-shot DSC-HX99 (2018).

Both fall into the “small sensor superzoom” category, but each speaks to a different era in camera design and technology. I spent extensive hands-on time putting them through real-world shooting scenarios, assessing everything from autofocus performance to image quality, ergonomics, and video capabilities. Here’s my detailed, no-nonsense comparison, designed to help you decide which might best suit your photographic needs today.

First Impressions: Size, Handling, and Design Ergonomics

Visually and physically, these cameras couldn’t be more different. The Nikon P100 gives you classic bridge camera heft with a DSLR-like shape, while Sony’s HX99 opts for a sleek, true compact form factor.

Nikon P100:
The P100’s grip is generous and comfortable for larger hands. Its SLR-style body, though bulkier, provides solid control confidence - especially if you like shooting with one hand around a firm, contoured grip. It feels weighty and well-balanced despite not being especially large. Buttons and dials are spaced out, which helps when shooting outdoors or with gloves.

Sony HX99:
In stark contrast, the HX99 is delightfully pocketable, almost pocket-sized. It weighs about half as much as the P100 and slips easily into small bags or even large pockets. Handling-wise, you get a smaller grip and more minimal physical controls, reflecting its compact ambitions. The lack of a deep grip might feel less secure in fast-paced shooting but gains huge points for portability.

Moving beyond pure dimensions, the HX99’s build quality feels solid with a slick matte finish, whereas the P100’s plastic-heavy exterior shows its age but remains durable enough for casual use.

Control Layout: Intuition Meets Efficiency

After the feel, the next crucial aspect is how one operates the camera, especially when speed matters. I spent time comparing control interfaces during my shoots in urban and nature settings.

Nikon P100:
The P100 offers a traditional bridge camera layout with dedicated buttons for exposure compensation, AF mode, and a top dial for quick shooting mode selection (manual, aperture, shutter priority). This design is pleasantly familiar for DSLR shooters moving into superzooms. Dual dials speed up exposure adjustments, and physical switches (like the zoom lever) have a tactile, reassuring feel.

Sony HX99:
Sony strikes a balance between compactness and control. While physical buttons are fewer, the addition of a touchscreen really aids operation. Touch-to-focus and menu navigation are smooth and intuitive, somewhat compensating for smaller buttons and fewer dedicated controls. The top dial works well, but cycling through modes requires more menu diving than the P100.

If I were shooting fast-moving subjects or in changing light, I’d prefer the Nikon’s tactile controls. For casual shooting with some touchscreen convenience, Sony’s design shines.

The Heart of Photography: Sensor and Image Quality

At the core, of course, is the sensor. Both cameras sport a 1/2.3-inch BSI-CMOS sensor, a common small sensor size used in compact and bridge cameras, but there are some notable differences.

Resolution:

• Nikon P100: 10 megapixels (3648×2736)
• Sony HX99: 18 megapixels (4896×3672)

Sony nearly doubles the resolution, which potentially allows for more detailed photos and cropping flexibility. However, more megapixels on a tiny sensor can have trade-offs in noise, which we’ll get into.

Image Processing:
Sony’s newer processing engine, developed well after Nikon’s Expeed C2 chip in the P100’s "vintage" architecture, results in noticeably cleaner images, better noise control in higher ISO ranges, and more vibrant, accurate colors. The P100’s output tends toward flatter, sometimes muddy images at ISO 800 and above.

Dynamic Range:
While neither camera can compete with larger APS-C or full-frame sensors, Sony’s HX99 delivers marginally better dynamic range, especially in bright highlight preservation. The vintage Nikon sensor shows earlier clipping in sunny scenes, requiring more care or post-processing to recover shadows.

In practical terms, I found the HX99’s image quality more satisfying for casual shooting, especially when lighting conditions are less-than-ideal. However, for bright daylight and straightforward shooting, the P100’s files remain respectable.

Autofocus Performance and Usability

Autofocus can make or break your shooting experience, especially in wildlife or sports photography where speed and accuracy matter.

The Nikon P100 uses a contrast detection AF system with no face or eye detection. By contrast, the SX99 benefits from Sony’s more advanced contrast detection with face and eye AF, continuous tracking, and multiple AF areas.

Autofocus Speed:
In daylight, both cameras lock focus efficiently on static subjects. The HX99’s AF feels faster and more confident at longer focal lengths, critical when zoomed in beyond 600mm equivalent.

Tracking Moving Subjects:
Sony’s continuous AF with tracking outperforms Nikon hands-down. On busy city streets or moving wildlife, Sony’s ability to stay locked on eyes or faces yields higher keeper rates.

Macro Focusing:
The P100 impresses with a close focus range of 1cm compared to Sony’s 5cm, useful for tight macro shooting of flowers or insects. However, Sony’s superior stabilization helps compensate when handholding macros.

For anyone prioritizing autofocus reliability and versatility across subjects - especially moving ones - the HX99 is the better performer. Nikon’s single-point contrast AF feels outdated by comparison.

What It’s Like to Compose: Viewfinders and Screens

Composing your image either through the EVF or LCD significantly impacts the shooting experience.

Viewfinder:

• Nikon P100: Electronic viewfinder with undisclosed resolution and coverage, enough for framing but noticeably lower resolution.
• Sony HX99: High-resolution EVF (638k dots), 100% coverage, comfortable magnification.

Sony’s EVF offers a bright, crisp view that makes manual focus and exposure adjustments easier, especially in bright sunlight. The P100’s EVF feels dimmer and more pixelated, making detailed composition tougher.

LCD Screen:
Sony’s HX99 features a 3-inch tilting touchscreen at 921k resolution, bright and responsive, ideal for live view focusing and menu interaction. Nikon’s P100 also has a 3-inch tilting screen but with about half the resolution (460k) and no touchscreen, making menus slower to navigate.

The HX99’s screen tilt and touchscreen facilitate shooting from high or low angles, critical for street, travel, and macro scenarios. The P100’s tilting screen is helpful, but the lack of touch controls slows workflow.

Zoom Range and Lens Performance

Here is where each camera stakes a claim in the superzoom territory.

Nikon P100: 26-678mm equivalent (approx. 26.1x zoom), aperture f/2.8-5.0
Sony HX99: 24-720mm equivalent (30x zoom), aperture f/3.5-6.4

While Sony offers slightly wider coverage on the short end and extending to a longer telephoto focal length, Nikon’s lens sustains a faster aperture at the widest zoom ranges. This potentially yields better shallow depth of field control and better low-light telephoto shooting.

Optically, Sony’s lens is sharper in the corners and broader zoom range is handy for distant details. Nikon’s lens produces less flare but suffers noticeably more chromatic aberration at long ends.

My tests in landscape and wildlife confirmed Sony’s greater reach and sharper output, particularly at long zooms. Nikon’s brighter aperture at wide angle helps in indoor or low-light portraits but less so outdoors handheld.

Stabilization and Burst Shooting

Effective image stabilization is essential for small sensor superzooms, given their lengthy zoom and relatively small pixels.

• Nikon P100 uses sensor-shift stabilization.
• Sony HX99 also has optical image stabilization but details vary.

Both deliver steady shots up to 600mm equivalents hand-held, but the HX99’s modern stabilization technology yields a more confident feel at maximum zoom. This also benefits video.

Regarding burst shooting speeds: both support 10 fps continuous shooting. However, Sony’s buffer and processing let you shoot this pace for longer bursts, useful for wildlife and sports.

Video Capabilities: Then and Now

This is one of the biggest areas where the 8-year gap shows.

Nikon P100:

• Full HD 1080p at 30 fps max.
• No microphone input or advanced video options.
• Uses H.264 codec.

Sony HX99:

• Shoots true 4K UHD (3840×2160) at up to 30p, plus 1080p at up to 120fps for slow-motion.
• Supports AVCHD and XAVC S codecs for better compression and quality.
• Includes built-in stereo mic with wind noise reduction, but no external mic input.
• Optical image stabilization aids smooth footage.

For casual video shooters or vloggers, the Sony HX99 is a tremendous leap forward, delivering sharp, fluid 4K footage in a pocketable body.

Battery Life and Connectivity

The P100’s EN-EL5 battery life is undocumented here but, based on experience, it runs roughly 250-300 shots per charge, typical for its vintage. The camera offers no wireless connectivity, requiring cables for image transfers.

The HX99’s NP-BX1 battery is rated for approximately 360 shots. More importantly, Sony includes Wi-Fi and NFC for wireless image transfer and remote control via smartphone apps - great for social shooters and travelers.

Software, File Formats, and Post-Processing Workflow

Another key difference is raw file support:

• Nikon P100 does not support RAW; only JPEG output is available. This can be limiting for those who want maximum control in post.
• Sony HX99 supports RAW, a major advantage for enthusiasts and professionals who like total editing flexibility.

Real-World Use Case Testing Across Photography Genres

To bring these specs to life, I shot both cameras extensively across multiple photographic scenarios:

Portraiture

Nikon’s brighter maximum aperture wide-angle helps with shallow depth and skin tone rendering indoors, but SX99’s face detection AF and higher resolution sensor deliver crisper images and better-focused eyes outdoors or when zoomed in. The HX99’s bokeh is less pronounced due to smaller aperture but compensates with better sharpness.

Landscape

Both cameras deliver adequate detail, but HX99’s higher resolution files show more fine textures and color gradation. Nikon’s lens flare control is better in direct sun, but the Sony’s longer zoom lets you also capture distant details. Neither offers weather sealing, so caution in harsh environments is advised.

Wildlife & Sports

Sony’s faster continuous autofocus, longer zoom, and sustained 10fps burst make it a clear choice for fast-moving subjects. Nikon’s AF limitations and slower autofocus tracking reduce keeper rates. Stabilization is better on the HX99, which helped pin sharp images handheld at full telephoto.

Street Photography

Here Sony’s compact size, quiet operation, and touchscreen win. Nikon’s bulk and louder zoom motor make it less discreet. However, P100’s faster lens aperture at wide angles still helps in low indoor light situations.

Macro

Nikon’s 1cm close focus outperforms the HX99’s 5cm minimum, but Sony’s steadier image stabilization and higher resolution compensate somewhat. Both perform adequately, with Nikon having the niche advantage.

Night/Astrophotography

Sony’s higher max ISO (12800 vs 3200) and better noise handling help night shooters. Nikon struggles with noise past ISO 800. Neither camera is a dedicated astro tool, but HX99 produces crisper low-light images overall.

Travel

Sony’s small footprint, Wi-Fi, and broader focal range make it ideal for carrying light and capturing a wide variety of scenes - from architecture to wildlife. Nikon’s bulkier design and older features weigh it down for prolonged trips.

Professional Use

Neither camera replaces professional-grade gear but Sony’s RAW support, better image quality, and higher video capabilities make it more adaptable for working photographers who need a lightweight backup or compact option.
