Canon SX730 HS vs Nikon Coolpix B700: A Deep Dive into Small Sensor Superzoom Showdown

As someone who has extensively tested hundreds of cameras, ranging from pro-grade workhorses to travel-friendly compacts, I find small sensor superzoom cameras hold a fascinating niche. They promise versatility with their hefty zoom ranges, packed into relatively pocketable bodies - but these compromises often raise questions about real-world usability and image quality. Today, we’re pitting two popular contenders in this segment against each other: Canon’s PowerShot SX730 HS and Nikon’s Coolpix B700.

Both released within a year of each other, the Canon SX730 HS (2017) and Nikon B700 (2016) target enthusiasts wanting dramatic reach without breaking the bank or wielding a bulky DSLR. Let’s break down how these cameras compare in terms of design, image quality, autofocus, and suitability across photography genres. My aim here is to provide you clear, practical insights based on rigorous hands-on evaluation so you can match a camera to your shooting style - and budget.

First Impressions: Ergonomics and Physical Design

When holding the Canon SX730 HS alongside the Nikon B700, the difference in form factor becomes instantly apparent.

The Canon is a decidedly compact, pocketable travel companion measuring 110x64x40mm and tipping the scales at just 300g. Its slab-style build and clean lines make it unobtrusive - the kind of camera you might slip into a jacket pocket for urban excursions or quick snaps on vacation.

In contrast, the Nikon B700 is bigger and heavier - more of a bridge camera with an SLR-like silhouette at 125x85x107mm and 565g. While still manageable for travel, it commands more presence, and you notice it hanging from your neck more than the SX730. The extended grip and more tactile controls lend it a semi-professional vibe, but that extra bulk might deter those prioritizing portability.

Ergonomically, Nikon’s generous grip and physical control dials provide a satisfying level of handling confidence. Meanwhile, Canon’s minimalistic approach leans towards simplicity, though some might find the smaller buttons and reduced grip less comfortable during extended shooting sessions.

Top-down perspectives further highlight these design philosophies:

Here, Nikon’s button layout is more extensive and logically spaced, ideal for quick adjustments. The Canon’s layout is streamlined but sacrifices some immediacy in favor of sleekness.

Quick takeaway: If portability and pocket-friendliness are your priorities, the Canon SX730 HS excels. For more substantial handling and physical controls - valuable in faster-paced shooting - the Nikon B700 feels more substantial and dependable.

Sensor and Image Quality: Punching Above the Sensor Size?

Both cameras share nearly identical sensor specs: 1/2.3-inch BSI-CMOS sensors with around 20MP resolution (Canon at 20.3MP, Nikon at 20MP). That sensor size and resolution combo is popular for superzoom compacts, but it comes with inherent trade-offs in noise performance and dynamic range, which we'll examine closely.

Despite the shared sensor size, differences emerge in image processing and software. Canon relies on the DIGIC 6 processor, while Nikon's processor details are less disclosed but known to be effective.

Resolution and Detail: Both cameras produce detailed JPEGs at their maximum resolutions (5184x3888), but due to the sensor limits, fine detail is capped by diffraction and noise suppression.

Dynamic Range: Neither camera offers extensive RAW support out of the box; Nikon is the only one featuring RAW capture - which is a significant advantage for serious post-processing. In practical terms, both cameras struggle with retaining highlight and shadow detail in high-contrast scenes typical of landscapes.

Low Light Performance: With max ISO 3200 and a small sensor, noise notably increases beyond ISO 800. Canon’s DIGIC 6 processor handles noise reduction conservatively but sometimes at the cost of detail. Nikon’s noise reduction is slightly more aggressive, leading to smoother but less detailed low-light images.

Let’s look at some comparative sample images to ground these observations:

Shots reveal Canon’s color rendition leans slightly warmer with good skin tones, valuable especially for portraits and casual snapshots. Nikon tends towards warmer saturation and richer contrast, which can enhance punchiness but may appear less natural in some scenes.

Both cameras have anti-aliasing filters - helpful to limit moiré but potentially softening very fine details.

Autofocus: Fast, Reliable Tracking Or Hit and Miss?

Autofocus is critical, especially in superzoom cameras where telephoto shots magnify subject movement and camera shake.

Both the SX730 HS and B700 feature contrast-detection autofocus systems with face detection and continuous tracking modes. Nikon adds selective AF area control, slightly enhancing compositional precision compared to Canon’s time-limited multi-area AF.

In real-world usage:

• Canon SX730 HS: Autofocus on the Canon is quick in good light, locking on faces efficiently with decent tracking in continuous mode. However, during low light or complex scenes, you may notice hunting and slowed focus confirmation. The center-weighted single-point AF is sometimes too restrictive for fast-moving subjects.

• Nikon B700: Nikon’s larger body houses a more refined AF algorithm with better subject tracking across multiple areas. In real-world testing on subjects like birds or fast-moving cars, the B700 maintained focus more consistently than the Canon.

Continuous shooting rates are comparable: Canon at 5.9fps and Nikon at 5fps - adequate for casual action shots but not professional sports firing. Neither supports electronic shutter or silent shooting, a limitation for quiet environments.

LCD Screens and Viewfinders: Framing and Interface

LCD size and articulation impact framing comfort, especially when shooting from awkward angles or in bright light.

• Canon SX730 HS: Features a 3-inch tilting but non-touch screen with 922k-dot resolution. The tilting mechanism allows for some flexibility but does limit overhead or waist-level shooting. The lack of touchscreen is a clear omission in 2017 standards, reducing menu navigation ease.

• Nikon B700: Its 3-inch fully articulated screen offers significantly more compositional freedom ideal for vlogging or low/high-angle shots. Notably, it has no touchscreen, mirroring Canon in that regard; both rely on buttons and dials for settings changes.

A major selling point for Nikon is its electronic viewfinder (EVF) with 921k-dot resolution and 100% coverage, invaluable for bright outdoor shooting where LCD glare is a problem. Canon offers no viewfinder - shooting must rely on the LCD exclusively.

In sunny conditions or when stability is paramount, the Nikon gives a tangible advantage.

Zoom Range and Lens Performance

Superzoom cameras live and die by their focal length and optical performance.

• Canon SX730 HS: Offers a 40x optical zoom ranging from 24-960mm equivalent with an aperture of f/3.3-6.9. The zoom range covers wide-angle to significant telephoto, ideal for travel and casual wildlife.

• Nikon B700: One-ups the Canon with an impressive 60x zoom from 24-1440mm equivalent, f/3.3-6.5 aperture, stretching reach to a remarkable telephoto length rare in compacts.

The extended reach has practical implications:

• Nikon’s 1440mm extends the ability to fill frames when shooting distant wildlife or sports events without cropping harshly.
• At max zoom, image stabilization becomes critical - both cameras feature Optical IS systems. Nikon’s is slightly more effective, delivering better steady handheld shots at extreme focal lengths.
• Image sharpness declines as expected near max zoom on both cameras due to lens diffraction and minor optical aberrations, but the Nikon maintains usable detail slightly farther out.

Stabilization and Burst Shooting: Benefits and Limitations

Both cameras implement Optical Image Stabilization (OIS), essential for the superzoom form to counteract shake.

• Canon: OIS provides good compensation up to moderate telephoto lengths but struggles beyond 600-700mm equivalent in my tests.
• Nikon: Stabilization is somewhat more aggressive and better calibrated for the longer 1440mm reach, allowing shots handheld at slower shutter speeds with less blur.

In terms of burst shooting, Canon’s 5.9fps is useful but limited by relatively shallow buffers; Nikon’s 5fps slows quickly during burst sequences. Both suit casual action but are ill-equipped for high-speed sports photography.

Video Capabilities: 4K Versus Full HD

Video is increasingly important, even for casual zoom cams.

• Canon SX730 HS: Maxes out at Full HD 1080p at 60fps (H.264 encoded) with stereo audio but no mic input or headphone jack. No 4K recording is offered.
• Nikon B700: Stands out by offering UHD 4K video (3840x2160) at 30fps or 25fps, alongside 1080p at varied frame rates up to 60fps. Audio is stereo but lacks external mic/headphone ports, limiting professional use.

Neither camera supports advanced video features like log profiles or zebra patterns, keeping video casual but solid.

Battery Life, Storage, and Connectivity

Battery endurance is often overlooked but essential during travel or all-day outings.

• Canon SX730 HS: Rated for approximately 250 shots per charge, which is modest and may necessitate extra batteries on longer trips.
• Nikon B700: Offers nearly 350 shots per charge, a meaningful advantage when hiking or attending lengthy sports events.

Both use standard SD/SDHC/SDXC cards with single card slots - no surprises here.

Connectivity-wise, both feature built-in Wi-Fi, Bluetooth, and NFC for image transfer and camera control via smartphone apps - modern essentials for instant sharing.
