When diving into the realm of small sensor superzoom cameras, particularly models released around 2015, the Nikon Coolpix L840 and Sony Cyber-shot DSC-HX90V frequently emerge as popular contenders. Both cameras cater to photographers seeking versatile focal ranges without the bulk or complexity of interchangeable lenses. Yet, they approach this niche from subtly different design philosophies and feature sets. Drawing from rigorous, hands-on testing in diverse photographic scenarios - ranging from portraiture to wildlife, video capture to travel photography - this deep dive compares these two models head-to-head, dissecting technical specs, real-world usability, imaging performance, and value proposition.

First Impressions: Size, Handling, and Build Quality

The L840 adopts a classic SLR-inspired bridge camera form factor with a noticeably larger body (114×89×96 mm, 538g) compared to the compact, pocket-friendly HX90V (102×58×36 mm, 245g). The Nikon’s heft conveys an immediate sense of stability and presence, appealing to photographers accustomed to DSLR ergonomics with a comfortable grip and straightforward control layout. In contrast, Sony’s smaller, sleeker chassis prioritizes portability and discreetness - qualities essential for street and travel photography.

While neither is weather-sealed or ruggedized, the L840's slightly more substantial build instills greater confidence in handheld shooting and rougher conditions, although the plastic construction remains standard fare at this price point. Conversely, the HX90V impresses with its compactness and light weight without feeling particularly fragile, demonstrating Sony’s prowess in miniaturizing superzoom functionality. Battery types differ too: Nikon’s use of readily available AA batteries (with an impressive 590-shot life) contrasts with Sony’s proprietary NP-BX1 lithium-ion pack offering around 360 frames per charge - suggesting Nikon favors convenience and longevity on trips where power outlets might be scarce.

Ergonomically, Nikon’s larger body allows better thumb and finger placement for stable handling during long telephoto zooming, although dedicated manual control buttons are limited (no aperture priority or shutter priority modes). Sony shines here by offering a fuller manual exposure suite that better serves enthusiasts wanting more creative control.

Interface, Controls, and Viewing Experience

Both models sport 3-inch tilting LCD displays with 921k-dot resolution, facilitating clear compositions and menu navigation. However, the HX90V’s screen also features a “selfie-friendly” flip angle, differing from Nikon’s fixed tilting design that does not cater to front-facing shooting. Neither implements touchscreen functionality, which aligns with their typical use cases - Sony leans more into compact and spontaneous shooting, whereas Nikon targets steady, zoomed-in shots.

Unlike the L840’s absence of any viewfinder, the HX90V boasts a 638k-dot OLED electronic viewfinder (EVF) with 100% coverage and 0.5x magnification. This is a significant advantage for shooting in bright environments or when framing precisely at long zooms. The lack of any EVF on Nikon handicaps it in direct sunlight or for users preferring eye-level composition, reducing compositional flexibility.

Sony’s broader control suite includes aperture priority, shutter priority, and full manual exposure modes, empowering photographers to fine-tune settings beyond simple auto or scene modes. Nikon’s lack of any manual modes limits the L840 largely to point-and-shoot or programmatic exposures, which may frustrate more serious users seeking nuanced exposure control.

Sensor, Image Quality, and Performance Under the Hood

At their core, both cameras feature a 1/2.3-inch CMOS sensor measuring 6.17×4.55mm - standard for superzoom compacts but inherently limited in physical size relative to larger APS-C or full-frame sensors. Noise control and dynamic range are therefore significant challenges here, necessitating robust image processing to maximize quality.

Sony’s HX90V packs an 18MP backside-illuminated (BSI) CMOS sensor, a technology known to enhance light sensitivity by repositioning wiring behind the photodiodes, resulting in somewhat better low-light performance and dynamic range relative to traditional front-illuminated sensors. Nikon’s L840 employs a 16MP CMOS sensor without BSI. While still competent, image tests reveal the Sony producing marginally cleaner images at ISO 800 and above, with slower noise ramp-up. The Nikon’s images exhibit slightly more luminance and color noise at boosted ISO settings.

Despite the slight edge to Sony, both cameras deliver roughly equivalent sharpness at base ISO under good lighting, with Sony marginally benefiting from its newer Bionz X image processor that more effectively reduces artifacts. Neither supports RAW capture - a notable limitation for professionals or serious amateurs who desire extensive post-processing latitude. Images are JPEG-only, with Sony offering a broader selection of aspect ratios (1:1, 4:3, 3:2, 16:9) and more refined white balance bracketing, beneficial in challenging light.

Color reproduction on skin tones is quite natural in both cameras, though Nikon’s tendency toward slightly cooler colors contrasts with Sony’s warmer palette. For portrait enthusiasts, the Sony’s improved autofocus face detection (including center-based AF point) facilitates reliable eye-level focus, yet Nikon also delivers respectable face-detection despite fewer precise AF areas.

Autofocus and Burst Shooting Dynamics

Both cameras utilize contrast-detection autofocus systems without phase detection. Sony’s HX90V’s AF is arguably faster and more consistent in good lighting, aided by its advanced processor and multi-area AF modes, achieving up to 10 fps continuous shooting - a clear advantage for sports, wildlife, or action photography. Nikon’s continuous burst rate tops out at a still-usable 7.4 fps but often falters during continuous AF scenarios due to slower processing and older contrast-detect algorithms.

Neither camera offers animal eye AF or sophisticated subject tracking, which is understandable given their price and sensor class; however, Sony’s inclusion of center AF and better multi-area tracking generally enables more responsive focus acquisition. Nikon’s lack of center-weighted AF means that its AF tends to focus on broader scene areas, sometimes resulting in less precise lock-on for small or fast subjects.

Lens and Zoom Capabilities

The core superzoom characteristic of these cameras is their respective fixed lenses with extensive focal ranges, critical for versatility in everything from sweeping landscapes to distant wildlife.

• Nikon L840: 23-855mm equivalent (38× zoom), f/3.0-6.5
• Sony HX90V: 24-720mm equivalent (30× zoom), f/3.5-6.4

While Nikon slightly edges Sony in zoom magnitude, the practical difference - the difference between 855mm and 720mm - is subtle for most photographers and may be offset by Sony’s more compact and optically stabilized lens design. Both lenses incorporate optical image stabilization (OIS), essential at long focal lengths to mitigate handshake blur. User tests affirm that both cameras perform well under typical conditions at telephoto extremes, but the Nikon’s wider zoom range is beneficial for wildlife shooters prioritizing maximum reach.

Macro focusing abilities favor Nikon, which can lock focus down to 1cm, allowing detailed close-ups of small subjects. Sony’s minimum focus distance of 5cm is less aggressive but still workable for casual macro needs.

Display and Interface Practicalities

Both cameras feature a tilting 3-inch LCD with identical 921k-dot resolution, offering similar viewing comfort and detail rendition. Nikon’s L840 screen tilts upward and downward but is not selfie-oriented, missing the mark for vloggers or portrait selfies, which hip younger audiences increasingly expect. Sony’s screen supports a front-facing tilt (180 degrees) to aid selfie framing and creative shooting angles, enhancing versatility for social media users.

Neither has touchscreen capability - an omission that restricts some intuitive focusing and menu navigation conveniences common in newer models.

Video Capabilities for Hybrid Shooters

When comparing videography potentials, both models provide full HD (1920×1080) capture, but implementation details differ:

• Nikon L840: 1080p recording limited mostly to interlaced frame rates (60i, 50i) with some progressive at 30p/25p, utilizing common MPEG-4 and H.264 codecs. Lacks mic or headphone inputs and eschews slow-motion or 4K modes entirely.

• Sony HX90V: Offers 1080p in progressive frame rates including 60p and 24p, and higher-quality AVCHD and XAVC S codecs - significant for videographers needing smoother motion and better compression. Built-in mic but no external microphone inputs hamper serious audio capture.

Neither camera provides internal 4K recording or advanced video features like zebras or waveform monitors, so they target casual users or travelers documenting memories rather than professional video shooters.

Eyeing the Details: Storage, Connectivity, and Battery

Both cameras accept SD card media, with Sony additionally accommodating Memory Stick Duo - a minor practical benefit mainly relevant to existing Sony system users. Wireless connectivity is built into both, with NFC offered, facilitating quick image sharing to compatible devices; however, Bluetooth support is absent, limiting seamless tethering options.
