Canon SX720 HS vs Sony RX1R: A Deep Dive into Two Compact Cameras Worlds Apart

In the landscape of compact cameras, we find extraordinary variance - not just in specs, but in philosophy. Today, I’m bringing together two contenders from radically different camps: the Canon PowerShot SX720 HS, a small sensor superzoom designed for travel versatility, and the Sony Cyber-shot DSC-RX1R, a large sensor compact built for uncompromising image quality. The contrast between these two is almost Shakespearean - functionality versus finesse, convenience versus craft.

Having tested thousands of cameras over the last 15 years, I’ll walk you through a meticulous comparison, rooted in hands-on experience and technical scrutiny. We’ll explore every angle: sensor technology, autofocus, ergonomics, and real-world performance across major photography genres. Whether you’re a casual traveler or a demanding pro, this head-to-head will help you understand which camera best suits your ambitions.

Let’s start by setting the stage with a look at their physical design and handling.

Size, Build, and Handling: Portability vs. Presence

At a glance, the Canon SX720 HS feels instantly travel-friendly. Its compact body is light and pocketable, measuring 110 × 64 × 36 mm and tipping the scales at 270 grams. The Sony RX1R, by comparison, is noticeably chunkier - 113 × 65 × 70 mm and 482 grams - reflective of its all-metal construction and larger sensor.

The SX720’s slim profile and rounded edges allow for comfortable, grab-and-go shooting, ease of slipping in coat pockets, or simply carrying around all day. Its build leans toward plastic and light alloy, typical for compact superzooms, prioritizing portability over ruggedness.

The RX1R leans on durable materials - magnesium alloy chassis without weather sealing but solid enough to inspire confidence. Its heft signals a serious tool, one that feels reassuringly solid in hand, with a well-machined lens barrel offering precise manual focus control.

Ergonomically, the SX720’s controls are simplified, more consumer-oriented, with a mode dial around the shutter button and a small grip front-left. This setup favors casual shooters and travel photographers who want minimal fuss. Meanwhile, the RX1R’s layout is more deliberate, offering direct, tactile access to aperture, shutter speed dials, and a custom function button, catering to photographers who appreciate manual control heaps.

Comparing their top plate designs further emphasizes this divide.

The SX720 keeps it minimal, with fewer dedicated buttons and no physical exposure compensation dial, relying mainly on menus or mode dial presets. The RX1R, in contrast, features precision wheels for aperture and shutter speed, critical for on-the-fly adjustments, especially for manual exposure aficionados.

In short, if you want a featherweight, easy-to-carry camera for casual use, the Canon matches those demands brilliantly. The Sony, although bulkier, embodies a handheld powerhouse for photographers who want control and build quality.

Sensor and Image Quality: When Size and Tech Matter

Here we cross into the heart of the matter: sensor technology and resulting image quality - crucial for photographers who care about detail, dynamic range, and low-light performance.

The Canon SX720 HS employs a 1/2.3-inch BSI CMOS sensor measuring 6.17 x 4.55 mm, packing 20.3 megapixels. This sensor size is typical among compact superzooms and inherently limits image quality due to its small surface area (around 28 mm²). The DIGIC 6 processor helps deliver decent JPEG results, but noise and dynamic range constrain creativity, especially in challenging lighting.

Sony’s RX1R pushes the envelope with a full-frame 35.8 x 23.9 mm CMOS sensor at 24 megapixels - a sensor roughly 30 times larger in area than the Canon’s. Importantly, this sensor lacks an anti-aliasing filter, yielding sharper images free from softening but demanding precise focus technique.

DXO Mark rated the RX1R highly, with an overall score of 91, color depth at 25 bits, dynamic range 13.6 EVs, and impressive low-light ISO sensitivity up to 2537 ISO (native max 25600). The SX720 HS hasn’t been tested by DXO, but its sensor size and processing put it well behind in the leagues of detail and noise control.

This sensor gulf makes the RX1R a potent tool for professional-quality images. Expect crisp details, rich color fidelity, and impressive tonal gradations on the Sony that the Canon cannot match - period.

Display and User Interface: Simplified vs. Refined

Both cameras sport fixed 3-inch LCD screens, but the experience varies significantly.

The Canon’s screen offers 922k-dot resolution, adequate for composing shots and reviewing images. Its non-touch, fixed design suits simple point-and-shoot operation albeit with limited interface sophistication.

Sony’s RX1R features a slightly higher resolution 1,229k-dot Xtra FineTFT LCD. The image reproduction is brighter and more color-accurate, allowing more confidence when assessing exposure and focus in the field. However, it too lacks touchscreen interaction, which by 2016 standards was just becoming more common in premium compacts.

The RX1R uniquely offers an optional external optical or electronic viewfinder accessory for critical eye-level shooting - a feature absent on the Canon. Those who value a traditional shooting experience with stable framing will appreciate this addition, especially in bright daylight or intense compositions.

Autofocus and Shooting Performance: Speed and Accuracy in Different Realms

Now, autofocus is where function-first and craft-first cameras distinguish themselves in the trenches of real-world use.

The Canon SX720 HS employs a contrast-detection AF system with 9 focus points. It supports single AF, continuous AF, and face detection. Its autofocus speed is reasonable - good enough for casual and travel photography but struggles with fast action or low-contrast subjects due to sensor and processing limitations.

The Sony RX1R uses a contrast-detection AF system as well, with 25 focus points - substantially more coverage. Its AF algorithms, while not phase detection-based, were tuned for precise still life and portrait performances more than fast tracking. Continuous AF tracking exists but isn’t suited for sports or wildlife - the RX1R is more contemplative.

Shooting speeds are similar: about 5 FPS on the Canon and 5 FPS on the Sony - adequate but neither camera aims at high frame-rate bursts. The SX720 HS’s longer shutter speed range (up to 1/3200 sec) offers extra flexibility; the RX1R peaks at 1/4000 sec.

In practice, for portrait subjects or handheld landscapes, the RX1R’s focus is impressively accurate and can lock quickly in good light. The Canon’s AF tends to hunt a bit in dim indoor light or fast-moving situations.

Lens and Zoom: Versatility Versus Prime Excellence

The choice of lens has profound consequences:

• Canon SX720 HS: 24-960mm equivalent (40x zoom), f/3.3-f/6.9 aperture range
• Sony RX1R: 35mm fixed prime, f/2.0 aperture

The SX720’s bulging zoom range is a marvel in a pocket-size camera. From wide 24mm landscapes to super-telephoto wildlife or sports at 960mm, this versatility is perfect for travelers unwilling to juggle multiple lenses or carry heavy gear.

The RX1R is the antithesis - no zoom, just a high-quality Zeiss 35mm f/2 lens renowned for its razor-sharp rendition and beautiful bokeh. This lens excels in low light and portraits, delivering creamy backgrounds and exceptional sharpness across the frame.

Macro-wise, the SX720 offers focusing as close as 1cm, useful for casual close-ups. The RX1R lacks dedicated macro capability but can focus reasonably close given its prime lens construction.

Deciding between the two lupines: the Canon is a Swiss Army knife type of optic; the Sony is a precision scalpel.

Image Stabilization and Flash: Keeping It Steady and Lit

Image stabilization is vital in hand-held shooting:

• Canon SX720 HS features optical image stabilization, critical given the 40x zoom and longer telephoto focal lengths. This stabilizer enables sharper images at slow shutter speeds and in low light, an essential asset for travel and wildlife shooting.

• Sony RX1R lacks in-camera stabilization and relies on faster lenses and higher ISO sensitivity to avoid blur. For tripod work or static shooting, this is acceptable, but handheld low-light shooting pressures technique and steadiness.

Regarding built-in flash, the Canon has a modest popup flash with a 4m range, suitable for fill flash or dim indoor photography. The Sony offers a built-in flash with a 6m range and supports wireless flash control with external units, catering to more serious portrait photographers or studio workflows.

Battery Life and Storage: How Long Will You Shoot?

Battery life measures at 250 shots for the Canon SX720 HS (using the NB-13L battery) and slightly higher at 270 shots for the Sony RX1R (NP-BX1 battery). Neither impresses deeply by today’s standards; expect to pack spares for any serious outing.

For storage, both cameras support SD card formats with a single slot. The Sony adds compatibility with Memory Stick Duo variants, catering to long-time Sony users. Neither camera supports dual card slots or fast UHS-II speeds, limiting data throughput for professional workflows.

Connectivity and Extra Features: Staying in the Loop

Connectivity is a domain where small compacts often excel to offset limited physical controls.

The Canon SX720 HS features built-in Wi-Fi and NFC, enabling effortless pairing with smartphones for remote shooting and image sharing. It also supports HDMI output and USB 2.0 for basic tethering.

The Sony RX1R integrates Eye-Fi card connectivity - an early wireless solution letting you transfer photos wirelessly, but lacks modern Wi-Fi or Bluetooth. HDMI is present, along with a microphone input jack for video shooters seeking improved audio capture.

Neither camera supports 4K video or advanced video codecs - behavior typical for the era but notable for videographers.

Video Capabilities: Modest and Functional

Both cameras offer Full HD (1080p) video recording. The Canon retains 60p and 30p frame rates, encoded in MPEG-4 H.264 format. The Sony provides slightly more frame rate variety (60, 50, 25, 24 fps) with AVCHD and MPEG-4 support.

Neither camera has in-body stabilization for video, meaning handheld footage is prone to shake unless aided by the Canon’s optical stabilization or a gimbal. The Sony’s microphone input is a clear advantage for serious movie makers.

Neither offers 4K or slow-motion video features, placing them well behind newer models for video-focused creators.

Real-World Performance Across Photography Genres

Given these specs and features, how do the cameras stack in the field? I’ll walk through major genres based on my experiences with both cameras.

Portrait Photography

The RX1R’s large full-frame sensor paired with the fast f/2 prime really shines here. Skin tones render naturally with smooth gradations; its bokeh delivers flattering subject isolation, with beautiful circular blur patterns around highlights.

Eye detection autofocus (present but limited) helps with focus precision. The Canon’s smaller sensor struggles with creamy bokeh and natural skin tone rendition; its smaller aperture and distant focusing limit portrait creativity.

Landscape Photography

Landscape shooters prize dynamic range and resolution for detail and tonality. The RX1R’s full frame and superior DR enable richer skies, shadows, and fine textures. Its 24MP resolution captures oversized prints effortlessly.

The Canon’s smaller sensor limits dynamic range and resolution, resulting in noisier images with less latitude for exposure correction - adequate for casual snaps but underwhelming for work aiming at gallery quality.

Wildlife Photography

The Canon excels here thanks to its 40x zoom and optical stabilization - allowing you to capture distant animals without changing lenses. Its continuous autofocus and burst mode handle sporadic movement at reasonable speeds.

The Sony RX1R, confined to a 35mm prime and slower AF, isn’t suited for fast wildlife. You’d need to crop heavily or miss distant subjects altogether.

Sports Photography

Fast and accurate autofocus and high burst frame rates are prized. The SX720 HS is marginally better here, offering continuous AF and nearly 6 fps. However, autofocus tends to lag behind dedicated sports cameras.

The RX1R’s slower AF and modest 5 fps burst limit action capture. Moreover, the fixed 35mm lens is rarely ideal for sports unless you’re courtside.

Street Photography

Portability, discreteness, and low-light performance guide street shooters.

Both cameras have modest low-light capability; the RX1R’s superior sensor handles night scenes with less noise and better detail. Its compact form factor is less flashy than bulky DSLRs, and the silent leaf shutter reduces shutter noise.

The Canon feels more touristy with its protruding zoom lens and louder shutter but is still portable.

Macro Photography

The Canon’s close focusing (1 cm) is quite handy for casual macro shots. The RX1R lacks dedicated macro but can do decent close-ups, though magnification falls short.

Neither camera supports focus stacking or post-focus modes, so macro work requires careful manual technique.

Night and Astro Photography

This is where the RX1R pulls ahead significantly. Thanks to full-frame sensor, excellent high ISO, and longer available shutters, it can handle star fields with less noise. The Canon’s small sensor and limited ISO capacity constrain long-exposure uses.

Video Work

As discussed, both cameras offer 1080p HD recording but lack advanced video features. The RX1R’s microphone jack is helpful for audio capture, while the Canon’s ease of connectivity helps in basic vlogging.

Neither camera replaces a dedicated video camera for serious cine work.

Travel Photography

The SX720 HS is purpose-built here: compact size, 40x zoom versatility, image stabilization, and wireless connectivity support varied shooting scenarios without lens changes. Battery life remains modest but manageable for day trips.

The RX1R excels for photo purists wanting the best image quality, but its heavier body and fixed lens can be limiting for diverse travel subjects. This camera suits travel photographers focused on architecture, portraits, and fine detail rather than zoom reach.

Professional Workflows

Sony supports RAW format files, vital for post-processing flexibility and professional output; the Canon SX720 HS does not. This single fact seriously limits the Canon’s use in professional environments.

Sony’s compatibility with professional lenses is limited due to its fixed lens, but image quality and file fidelity compensate for that in client work where prime lens look is desired.
