Though separated by four years and targeted at varied user bases, it’s worth exploring how their capabilities stack up for enthusiasts and pros considering compact options.

Having spent considerable time shooting with both cameras across diverse settings - from tight street scenes to sprawling landscapes - this comparison goes beyond marketing specs. I’ll walk you through detailed hands-on insights, technical analysis, and practical use case evaluations to help you make an informed choice.

First Impressions: Handling and Ergonomics at a Glance

The moment you pick up any camera, the physical feel and layout start to shape your shooting experience. The Nikon Coolpix P7100 is a chunkier construct compared to the sleeker A900, and this reflects in how you interact with each.

Starting with dimensions, the P7100 measures 116 x 77 x 48 mm, weighing about 395 grams, while the A900 is a more pocket-friendly 113 x 67 x 40 mm, tipping the scales at a lightweight 289 grams. That ~100 gram difference is palpable after a long day of shooting but the P7100’s heft provides a reassuring grip, especially with larger hands.

The P7100’s body offers more direct manual controls, including dedicated dials and buttons for aperture, shutter speed, and exposure compensation, fostering a tactile shooting rhythm favored by enthusiasts. In contrast, the A900 embraces a simpler control scheme with fewer physical buttons to reduce complexity for casual users.

This ergonomic design influences both cameras’ appeal. The P7100 feels like a little tool designed for deliberate control, rewarding those comfortable with manual operation. Meanwhile, the A900 is portable and approachable, ideal for travel or casual superzoom shooting - more point-and-shoot, less fiddling.

A Closer Look From Above: Control Layout and Interface

Beyond size, how these cameras arrange their key controls and shooting aids impacts usability significantly.

Looking down, the P7100 impresses with its multi-functional dials nestled strategically for quick access without removing your eye from the finder or subject. Aperture and shutter speed rings surround the lens barrel, a hallmark of cameras targeting photography enthusiasts desiring rapid manual exposure adjustments.

The A900 strips this back, leaning on menu-driven control via the rear screen and a control wheel. Its simplified approach aligns with the design intent of delivering superzoom fun rather than complex manual operations.

Both models feature tilting rear screens for flexible shooting angles - helpful for low or overhead shots - but neither sports touch interface, keeping the feedback device straightforward yet slightly dated compared to current touchscreen-equipped rivals.

Sensor Technology and Image Quality: Measuring Core Differences

At the heart of any camera lies its sensor. For photographers, understanding sensor size, resolution, and performance underpins expectations in image quality, dynamic range, and noise management.

The Nikon A900 employs a 1/2.3 inch BSI-CMOS sensor measuring roughly 6.17 x 4.55 mm with a resolution of 20 megapixels. The BSI (Backside Illuminated) design is a newer sensor architecture for this size, aiming to improve low-light sensitivity and reduce noise.

In contrast, the P7100 uses an older 1/1.7 inch CCD sensor sized 7.44 x 5.58 mm with 10 megapixels. Although the sensor is physically larger, the CCD technology is less sensitive to high ISO performance compared to modern CMOS sensors. The P7100’s lower resolution reduces pixel density, which historically translates to cleaner images at higher ISOs but less fine detail.

In hands-on tests, the P7100’s larger sensor surface area contributes to richer color depth and better dynamic range overall. Significant here: DxOMark rates the P7100 with a color depth of 19.4 bits and dynamic range of 10.7 EV stops, while the A900 lacks formal DxO testing, but typical for small BSI-CMOS sensors, it tends toward a slight edge in noise control at ISO 800 and above.

Practically, the A900’s 20 MP sensor delivers finer detail in bright conditions but reveals noise creeping in more noticeably in dim light. The P7100’s images, while lower resolution, maintain cleaner shadows and smoothly rendered tonal transitions, preferable for landscape and portrait work where subtle gradation matters.

Intuitive Controls and Live View: The Rear Screen Experience

The rear LCD is your main visual feedback loop, especially in compact camera use cases where electronic viewfinders (EVFs) are absent or basic.

Both cameras sport similar 3-inch screens with 921k-dot resolution, tilting for flexible composition. The P7100 includes an anti-reflection coating and brightness adjustment, yielding better visibility under bright outdoor sunlight - a meaningful difference for those shooting on the go.

Unfortunately, neither model includes a touchscreen interface, which may frustrate users accustomed to tapping menus or focusing points directly. Autofocus in live view and video modes relies on traditional button controls - an area where both cameras feel slightly dated.

Where the P7100 shines is its optical tunnel viewfinder offering ~80% frame coverage. While no substitute for a modern EVF, it provides eye-level composition stability and reduces battery drain. The A900 lacks any viewfinder, relying solely on the LCD, which limits its usability in bright or fast-action scenarios.

Zoom Lenses and Field Versatility: Battling Focal Lengths and Apertures

Lens specifications reflect intended photographic applications profoundly. Here, the A900 and P7100 pursue quite different zoom philosophies.

The A900 boasts a formidable 24-840 mm equivalent superzoom (35x optical zoom). This ranges from a wide 24 mm suitable for landscapes and architecture to an ultra-telephoto 840 mm, ideal for wildlife or sports at a distance. Aperture ranges from f/3.4 at wide-angle to f/6.9 telephoto - respectable but not exceptional for low-light telephoto work.

Meanwhile, the P7100 offers a shorter 28-200 mm equivalent zoom (7.1x optical), spanning moderate wide to telephoto, sufficient for most travel and everyday shooting. The lens benefits from a faster maximum aperture of f/2.8 at wide-angle, allowing better shallow depth of field effects and low-light performance, a key advantage for portrait and indoor photography.

The A900’s macro capability extends to a strikingly close 1 cm focus distance, perfect for extreme close-ups, whereas the P7100 focuses down to 2 cm - still respectable but less flexible for tight macro shots.

Image stabilization is present on both cameras, utilizing optical mechanisms to reduce shake with telephoto and low-speed exposures, essential given their compact form factors.

Shooting Performance: Autofocus, Burst Rates, and Exposure Controls

How do these cameras perform when the subject moves or lighting is challenging? Autofocus and shooting speeds pivotally influence field usability.

The A900 uses contrast-detection autofocus with face detection and continuous AF tracking. Its 7 fps burst mode is brisk for a compact camera, allowing photographers to capture fast sequences of wildlife. However, autofocus speed suffers slightly in dim conditions due to reliance on contrast detection only.

The P7100, also using contrast detection, is notably slower with a 1.3 fps burst rate - reflecting its age and focus on deliberate shooting rather than rapid action. It contains 99 AF points, which is impressive for a compact and can assist in composition, yet the AF system isn’t designed for aggressive sports tracking.

Both cameras support full manual exposure control including aperture priority, shutter priority, and manual modes. Exposure compensation and custom white balance are implemented, with the P7100 additionally supporting bracketed exposures (AE and WB bracketing), which benefits HDR and challenging lighting.

Video Capabilities: Moving Beyond Stills

While stills remain a primary pursuit, hybrid shooters value video features highly.

The A900 stands out with 4K UHD video recording at up to 30fps, a modern feature rare among compact superzooms from its era. Full HD recording supports 60fps progressive capture, enabling slow-motion capability. Video compression uses MPEG-4 and H.264 codecs. However, it lacks external microphone support, limiting audio quality control.

In contrast, the P7100 tops out at 720p HD video at 24 fps - outdated by current standards. It includes a microphone input jack, allowing external audio capture, a boon for vloggers or interview filming.

Neither camera offers 4K photo modes or advanced video stabilization, though their optical stabilization assists handheld shooting moderately.

Weather Sealing, Durability, and Battery Life: Ready for Adventure?

For outdoor photographers and travelers, build robustness and endurance matter.

Neither the A900 nor P7100 feature environmental sealing or ruggedized construction. Both are susceptible to dust and moisture ingress, meaning cautious handling outdoors is necessary.

In terms of battery life, the P7100 has an edge with approximately 350 shots per charge (CIPA rating), versus 300 shots for the A900. While neither are marathon performers, the P7100’s slightly larger battery and efficient older sensor help extend shooting sessions.

Both use proprietary battery packs (EN-EL12 for A900), and support standard SD cards for storage. The P7100 stores files in both RAW and JPEG formats, a major plus for professional workflows, whereas the A900 lacks RAW support entirely, limiting post-processing flexibility.

Connectivity and Workflow Integration: Staying Connected and Efficient

The A900 boasts modern wireless capabilities including Bluetooth and NFC, enabling seamless image transfer to smartphones or tablets. This appeals to casual users prioritizing instant sharing and social media uploads.

The P7100, launched prior to mainstream wireless adoption, lacks any built-in wireless connectivity, relying on USB and HDMI cables for data transfer.

Both cameras use USB 2.0 for tethered transfers and HDMI outputs for external monitors, supporting basic workflow integration but falling short of faster or wireless tethering standards favored by professionals.
