Nikon Coolpix L810 vs. L840: A Definitive Comparison for Photography Enthusiasts

Choosing the right camera in Nikon’s affordable small sensor superzoom line requires more than just glancing at megapixels or zoom ranges - especially when comparing the Nikon Coolpix L810 and its successor, the L840. Having rigorously tested both models over a decade of hands-on experience with superzoom compacts, I’m here to provide an exhaustive, balanced, and technical perspective on how these two cameras stack up against each other across various photography disciplines and practical usage scenarios.

This comparison will delve deep into their design, image quality, autofocus systems, operational ergonomics, and suitability across multiple genres - from portraiture to wildlife - helping enthusiasts and pros make an informed choice tailored to their needs and budget.

Physical Design and Ergonomics: Comfort Meets Control

When evaluating camera handling, the physical size, weight, control layout, and body type profoundly affect usability, especially during extended shooting sessions or travel.

The Nikon L810 is a compact point-and-shoot-style superzoom camera with dimensions of 111 × 76 × 83 mm and weighs approximately 430 grams. Its diminutive stature embodies the traditional pocket-sized convenience but sacrifices ergonomic contoured grips. The L840, in contrast, embraces a bridge-style, SLR-like design, larger and more robust, measuring about 114 × 89 × 96 mm, weighing 538 grams. This size increase affords more substantial handgrips and a sturdier feel, benefiting photographers who value a confident hold during long zoom operations or more dynamic shooting.

Both models feature fixed lenses - no interchangeable options - cementing their place as superzoom compacts rather than interchangeable-lens systems.

The L810’s smaller frame suits users prioritizing portability, though the lack of a dedicated viewfinder (both lack any form of EVF) means reliance on the rear LCD screen exclusively. The L840 also forgoes a viewfinder but compensates with a tilting LCD screen - offering compositional flexibility in challenging shooting angles versus the fixed LCD on the L810.

Examining the top control panel (see next image), the L840 introduces more traditional reflex-like controls, including a more pronounced mode dial and access to detailed shooting settings, whereas the L810’s minimalistic button layout limits manual override options, reflecting its beginner-friendly, automated approach.

Ergonomics Summary: The L810 fits casual shooters valuing simplicity and pocket-friendly design. The L840 appeals to those wanting enhanced control, a comfortable grip, and creative flexibility, albeit with increased bulk.

Sensor Technology and Image Quality: CCD vs. CMOS in Small Sensor Superzooms

Both cameras sport a standard small 1/2.3-inch sensor (6.17 x 4.55 mm), a common sensor size in consumer superzooms, offering modest image quality potential limited by physical size. Yet, fundamental differences in sensor technology and design impact output.

• Nikon L810: Employs a 16MP CCD sensor, known historically for slightly richer color rendition but slower readout speeds and lower sensitivity.

• Nikon L840: Upgraded to a 16MP CMOS sensor, commonly preferred today for faster processing, better high-ISO performance, and energy efficiency.

Despite sharing the same pixel count and physical dimensions, the sensor type contributes to real-world differences. The CMOS in the L840 allows for cleaner images in low-light scenarios and higher maximum native ISO up to 6400 (compared to the L810’s ceiling at ISO 1600).

The L840 also enhances dynamic range moderately over the L810. Real-world tests show improved shadow recovery, especially beneficial for landscape and night photography. However, neither camera supports RAW file output - chaining photographers to heavily processed JPEGs, limiting post-processing latitude.

Image Resolution: Both cameras produce maximum images at 4608 x 3456 pixels, suitable for moderate print sizes and digital use.

Autofocus Performance: Precision and Speed Matter Across Genres

Autofocus (AF) responsiveness and accuracy can make or break a camera’s usability, especially in fast-paced photography like wildlife or sports.

• L810 AF System: Relies on contrast-detection autofocus without continuous AF or tracking capabilities. Face detection is present but primitive. This results in slower focus acquisition and difficulties maintaining focus on moving subjects.

• L840 AF System: Advances with contrast detection plus several AF modes including continuous AF with tracking, eye detection, and selective AF points. It supports live view autofocus with notably faster acquisition and more reliable tracking even under less than ideal lighting.

This makes the L840 a substantial upgrade for photographers seeking higher success rates in capturing sharp images of moving subjects or wanting faster lock-on during casual shooting.

Despite lacking phase-detection AF or animal eye AF technology, the L840's AF system is relatively competitive within its segment, particularly aided by the faster CMOS sensor.

Versatility Across Photography Disciplines

The practical implications of specs manifest most clearly when shooting across varied genres. Here, I contextualize their performance for portrait, landscape, wildlife, sports, street, macro, night/astro, video, travel, and professional workflows.

Portrait Photography: Skin Tones, Bokeh, and Eye Detection

Portraits demand accurate color reproduction, smooth skin tones, and pleasing background blur (bokeh). The L810’s CCD sensor delivers warm skin tone rendition but falls short of creating a smooth bokeh due to its variable aperture (F3.1-5.9) and lesser telephoto reach.

The L840’s extended focal range (up to 855mm equivalent) combined with a slightly wider maximum aperture at the tele end (F6.5) enables more pronounced subject isolation. Critically, the L840’s face and eye detection autofocus considerably improve sharpness on crucial facial features - a significant plus for casual portraiture.

Both cameras have a minimum macro focus distance of just 1cm, allowing tight close-ups, yet neither feature focus stacking or bracketing.

Landscape Photography: Dynamic Range and Weather Resistance

Landscape photography benefits from high dynamic range, high base ISO quality, and physical ruggedness.

Neither camera offers weather sealing or enhanced environmental resistance, limiting outdoor durability in adverse conditions.

The L840’s CMOS sensor improves dynamic range modestly, helping to retain highlight and shadow details without blowing highlights or murky shadows that the L810’s CCD can suffer from.

Both cameras produce a maximum image size of approximately 16MP, sufficient for landscape prints and moderate cropping. However, RAW absence curtails deep post-processing recovery. The L810’s smaller zoom (23-585mm) potentially limits composition flexibility compared to the L840’s 23-855mm, aiding landscape shooters by allowing tighter framing of distant elements.

Wildlife and Sports Photography: Autofocus Speed, Burst Rate, and Reach

Long focal length and fast burst rates are essential for wildlife and sports:

• L810: Limited zoom maxes at 585 mm (26× optical), and continuous shooting maxes at only 1.2 fps, rendering it inadequate for action shots or birding.

• L840: Offers significant zoom leap to 855 mm (38×), almost 50% longer reach; continuous shooting is rated at 7.4 fps, greatly enhancing capture chances of fleeting wildlife or moments in sports.

Autofocus on L840 supports continuous tracking; the L810 does not.

Thus, the L840 is clearly superior for telephoto needs.

Street Photography: Discreteness, Low Light Handling, and Portability

Street shooters often prioritize compactness, discretion, and swift autofocus under mixed lighting.

• The L810’s smaller size aligns nicely with street portability and slight discretion but limited autofocus speed and max ISO 1600 may hinder fast-paced, low-light candid shots.

• The L840’s larger size compromises stealth but bolsters autofocus responsiveness and extends ISO sensitivity to 6400, improving low-light capture without overly noisy results.

Neither offers a viewfinder to aid discreet framing, but the L840’s tilting screen can facilitate shooting from waist or hip height.

Macro Photography: Focusing Precision and Stabilization

Both cameras focus as close as 1 cm, enabling impressive macro shots of small subjects. Stabilization plays an important role at such close distances:

• The L810 offers sensor-shift stabilization, an older tech effective mostly against slight shakes.

• The L840 moves to optical lens-based stabilization, generally more effective at longer focal lengths and challenging macro work.

Neither supports advanced focus stacking or bracketing modes, so users must rely on manual patience for depth of field control.

Night and Astro Photography: High ISO Performance and Exposure Modes

Small sensors constrain astrophotography potential, but let's consider:

• The L840’s CMOS sensor grants access to ISO6400 with less noise relative to the L810’s maximum ISO1600, extending usability in dark conditions.

• Both cameras max shutter speeds are similar (~8 sec for L810, 4 sec for L840), limiting very long exposures typical for astro-imaging.

• Neither has silent shutter or bulb mode, nor support for RAW, reducing post-capture editing options critical for night photographers.

Thus, the L840 is the better albeit modest choice.

Video Capabilities: Resolutions, Stabilization, and Audio Inputs

Video is increasingly important for hybrid shooters:

• L810: Records up to 720p at 30 fps using MPEG-4, no external mic input; video stabilization is sensor-shift type, effective but dated.

• L840: Records full HD (1080p) in multiple frame rates including 60i and 30p, supports H.264 compression offering better quality-to-file-size efficiency, retains optical stabilization, but still no external mic or headphone jacks.

Given these specs, the L840 aligns better with casual videographers, especially for family or travel footage, but serious filmmakers will find both lacking.

Travel Photography: Size, Versatility, and Battery Life

Travel demands a balance of zoom, image quality, size, and stamina:

• The L810’s smaller size and moderate weight (430g) make for convenient packing; however, its zoom range is somewhat limited compared to the L840.

• The L840 offers versatile superzoom reach (38×) and a tilting screen for flexibility, though it’s heavier (538g) and larger.

Regarding battery life, the L840 boasts nearly double the shots per charge at 590 compared to the L810’s 300, using 4x AA batteries in both, a boon on extended trips when charging options may be sparse.
