Canon SX740 HS vs Nikon Coolpix L840: A Hands-On Dive Into Two Small Sensor Superzooms

When compact superzoom cameras come to mind, Canon's PowerShot SX740 HS and Nikon's Coolpix L840 often draw comparisons. Both cater to enthusiasts craving a vast zoom range in pocketable - or near pocketable - bodies without the fuss of changing lenses. But owning one over the other means weighing different priorities: image quality, ergonomics, speed, or pure zoom power. With over 15 years testing cameras and having pushed hundreds of superzooms through rigorous field trials, I’m here to break down how these two stack up across the spectrum - from portraiture to wildlife, landscapes to video, and everything in between.

Let’s embark on a comprehensive, image-rich exploration, balancing technical insights and real-world usability to help you decide which might be your next trusty companion.

First Impressions: More Than Skin Deep

At a glance, it’s clear these cameras aim at different handling experiences despite sharing the small sensor superzoom category. The Canon SX740 HS comes in a sleek, compact design - no frills, lightweight, elegantly simple with a plastic body focused on portability. The Nikon L840 takes a more bridge-ish, DSLR-inspired approach with its heftier body and pronounced grip, promising a steadier hold.

Handling and Ergonomics

The Canon packs a surprisingly nimble 299 grams into dimensions of 110 x 64 x 40 mm - ideal for travel and street photographers valuing discretion and lightness. Meanwhile, Nikon’s L840 weighs almost twice that at 538 grams with a bulky 114 x 89 x 96 mm size footprint, definitely something you’d stash in a secondary bag rather than pocket your jeans.

Handling-wise, Canon’s minimalist button layout supports quick access without clutter, though some may find the reduced physical controls limiting. Nikon’s bridge style means a more substantial grip, larger handhold, and a familiar experience for DSLRs users, though portability takes a backseat. Neither camera offers weather sealing, so rough outdoor or landscape photographers will want to tread carefully.

Design Details Up Top: Control Freak’s Delight or Simplified Ease?

Looking down from above reveals striking differences in design philosophy.

The Canon’s top deck is modest but efficient with a dedicated mode dial, zoom lever integrated neatly into the shutter button, and a well-placed power button. Its approach is minimalistic yet sufficient for those who prioritize ease over sprawling control arrays.

Nikon’s L840, true to its bridge camera DNA, includes a zoom lever encircling the shutter, a dedicated mode dial, and a command dial for swift adjustments. The presence of more tactile dials and buttons caters to photographers who want finer control on the fly, such as exposure adjustments or scene modes.

Canon focuses on streamlined handling that fits in your palm; Nikon equips the user for manual intervention but demands a heftier hand.

Peering Into the Heart: Sensor & Image Quality

Despite looking similar on paper, sensor and processing tech define much of the imaging experience.

Both cameras employ a 1/2.3" type BSI-CMOS sensor, measuring 6.17 x 4.55 mm with a 28.07 mm² sensor area. This sensor size is a common baseline for compact superzooms but known to fall short in image quality compared to larger APS-C or full-frame sensors.

• Canon SX740 HS boasts 20.3 effective megapixels, processed through the modern DIGIC 8 engine.
• Nikon L840 offers 16 effective megapixels processed via an unspecified older engine (the announcement was back in 2015).

Why does this matter? More megapixels mean higher resolution when cropping or printing large, and the DIGIC 8 is a newer generation processor with enhanced noise reduction and detail preservation.

From hands-on experience, Canon’s sensor-plus-processor combo delivers clearer images with slightly better detail rendition and less noise at higher ISOs up to its maximum 3200 ISO limit. Nikon pushes ISO to 6400 but sacrifices image quality with much more pronounced noise and diminished detail. Dynamic range in both cameras is modest - typical for 1/2.3” sensors - but Canon nudges ahead with marginally better highlight retention in high-contrast scenes.

Viewing Life Through the Backscreen

Since neither model sports an electronic viewfinder (EVF), the rear LCD screen becomes vital for framing and reviewing images.

• Both have 3-inch tilting screens with almost identical resolutions: Canon with 922k dots, Nikon at 921k - negligible quality difference.
• Canon’s tilting screen flips up to 180 degrees, embracing selfie and vlogging trends.
• Nikon’s tilt is more basic, useful for low or high angle shooting but without the full flip convenience.

Neither camera features touch sensitivity, leaving physical buttons and dials for navigation. The simplicity on Canon’s interface reflects its beginner-friendly slant, while Nikon's menu system is more traditional but somewhat dated and less intuitive by today’s standards.

For composing quick street shots or rapid wildlife bursts, Canon’s brighter and more versatile screen usability gives it a slight edge in the field.

Autofocus and Burst: Catching the Action When It Counts

Autofocus (AF) performance often makes or breaks a camera’s usability across genres like wildlife and sports.

Canon’s newer DIGIC 8 engine powers fast contrast detection AF with impressive face and eye detection, which reliably nails sharp focus on portraits and moving subjects. Nikon’s AF feels a touch slower and less confident in low contrast or low light, partly because its processor comes from an earlier generation.

The continuous shooting speed is another point of contention: 10 fps on Canon vs. 7.4 fps on Nikon. In tracking fast-moving wildlife or sports action, those extra frames make a tangible difference, increasing your chances of capturing the decisive moment.

Portrait Photography: Skin Tones and That Cinematic Bokeh

Portrait shooters crave soft, natural skin tones, precise eye detection, and creamy bokeh to separate subject from background - even more challenging on small sensor superzooms.

Both cameras offer face and eye detection AF; however, Canon’s system is more consistent in locking onto eyes quickly. This makes portraits less of a gamble, especially in changing light.

Key differentiators:

• Canon SX740 HS: The 40x zoom with a 24-960 mm (equivalent) lens at f/3.3-6.9 aperture range produces decent background blur at telephoto ends, although don’t expect full-frame style bokeh – depth of field inherently remains broad due to sensor size.
• Nikon L840: Slightly wider lens at 23-855 mm f/3.0-6.5 but similar shallow depth. The f/3.0 max aperture on the wide end is marginally brighter but rarely used for portraits.

Color rendering by Canon proves warmer and more flattering in controlled portraits, with Nikon occasionally leaning toward cooler tones, requiring post-processing tweaks.

Landscapes and Scenery: Resolution and Dynamic Range in Focus

Landscape photographers prioritize resolution, dynamic range, and durability.

• Canon: 20.3 MP gives sharper, more detailed images at base ISO with moderate dynamic range superiority.
• Nikon: 16 MP is sufficient for web usage and prints up to 8x10 inches but won’t yield the same detail when cropping or printing large.

Neither camera offers weather sealing or robust build for harsh environments - crucial for serious landscape hikers. Nikon’s larger grip helps stable handheld shots, but Canon’s image stabilization does a marginally better job suppressing shake at longer focal lengths.

Zoom and Telephoto Power: How Far Can You Go?

Superzoom enthusiasts live for reach, and here both cameras shine but with subtle differences.

• Canon SX740 HS: 24-960 mm equivalent (40x optical zoom)
• Nikon L840: 23-855 mm equivalent (38x optical zoom)

Canon’s extra reach at the tele end gives an advantage for distant subjects, particularly wildlife and sports where standing your ground is the norm.

Combined with Canon’s optical image stabilization, this extends practical hand-held usability well into the super-telephoto territory.

Wildlife and Sports: Speed and Precision Under Pressure

Fast autofocus and burst rates are critical here.

Canon’s 10 fps burst rate and reliable face/eye tracking make it the stronger choice. Nikon’s slower 7.4 fps and less agile focusing don’t keep pace with fast action subjects. For expansive wildlife environments or fast-moving sports, the Canon SX740 HS emerges as the more responsive camera.

Street and Travel Photography: Weighing Discretion and Versatility

Street photographers value portability and quick responsiveness.

Canon’s lightweight and compact setup wins emphatically here. The lack of a viewfinder could be a drawback for some, especially in bright daylight, but the articulating screen helps with candid, low-angle shots discreetly.

For travel, Canon offers reasonable battery life (~265 shots) and supports UHS-I SD cards - standard but not cutting edge. Nikon’s battery life is substantially longer (590 shots) using AA batteries, a double-edged sword: bulky but easy to replace globally.

Macro Capabilities: Getting Up Close and Personal

Both cameras boast a macro focusing distance of 1 cm, typical for fixed lens superzooms.

Canon’s optical image stabilization combined with a sharper sensor produces crisper close-ups with fine detail retention.

Nikon offers versatile macro but less clarity and more noticeable softening around edges.

Night and Astrophotography: Pushing ISO and Exposure Limits

Small sensor cameras struggle with astrophotography, but it’s still worth assessing high ISO performance.

Canon’s ISO maxes out at 3200 native, with effective noise control up to 1600 ISO thanks to DIGIC 8. Nikon extends ISO to 6400 but at the cost of heavy noise and loss of detail, limiting its usability.

Neither camera features bulb mode or advanced exposure controls favored by astrophotographers, but Canon’s slower 15 second shutter speed allows some low-light experimentation.

Video: Moving Pictures and Sound

Video specifications highlight Canon’s modern advantages:

Canon’s leap into 4K sets it apart, appealing to vloggers or travelers craving crisp footage with some zoom. However, absence of microphone inputs limits professional audio applications.

The Nikon’s full HD at 60i/50i is solid but dated, and the lack of 4K might disappoint videography enthusiasts.

Professional Reliability and Workflow Integration

Both cameras lack features prized by pros:

• No raw capture (only JPEG), limiting post-processing flexibility.
• No weather sealing or rugged construction for demanding shoots.
• No electronic viewfinder for precise manual framing.
• Limited manual exposure controls on Nikon (no aperture, shutter priority modes; Canon offers manual exposures).

For professionals, these models serve best as lightweight backups or quick-shoot tools rather than primary cameras.

Connectivity, Storage, and Battery

Connectivity-wise:

• Canon offers Bluetooth, NFC, and built-in Wi-Fi, facilitating immediate image transfer and remote shooting.
• Nikon includes NFC and Wi-Fi but lacks Bluetooth, making Canon’s ecosystem more versatile.

Storage compatibility is nearly identical - SD/SDHC/SDXC cards (UHS-I for Canon).

Battery is a tradeoff: Canon’s rechargeable lithium-ion battery supports a full day of casual shooting, but Nikon’s AA battery system ensures you won’t be stranded without spares anywhere but adds weight.

Price-to-Performance: Is the Grass Greener?

With street prices hovering around $400 for both cameras, the choice boils down to features vs handling preferences.

Canon’s newer processor, 4K video, better autofocus, and compactness justify a slight premium if you value modern tech and portability.

Nikon’s L840 appeals to those seeking a rugged grip, longer battery endurance, and slightly larger lens aperture at the wide end - though technology is noticeably older.
