Head to Head: Canon ELPH 340 HS vs Sony A7 IV - Which Camera Suits Your Photography Journey?

As someone who’s tested thousands of cameras from pocket compacts to pro-grade mirrorless systems, I’m fascinated every time I place two markedly different models side by side. Today, I dive deep into comparing two cameras that cater to very different photographers - the Canon PowerShot ELPH 340 HS, a no-fuss ultracompact from 2014, and the Sony Alpha A7 IV, a state-of-the-art full-frame mirrorless flagship released in 2021.

Both cameras excel in their respective realms and budgets. But what’s the real-world impact of their vastly different sensor sizes, handling, autofocus, and shooting features? From portraits to landscapes, wildlife to street photography, and video to travel, I’ll share my hands-on insights and technical analysis so you can decide which camera aligns best with your creative goals.

Let’s start by sizing them up.

Small vs. Substantial: Handling and Ergonomics

The very first difference becomes immediately apparent when you place the Canon ELPH 340 HS next to the Sony A7 IV. The Canon is truly pocketable - its compact dimensions at 100x58x22mm and featherweight 147g make it a discreet travel companion, ready in a heartbeat. In contrast, the Sony A7 IV is a professional SLR-style mirrorless that weighs nearly 700g with dimensions of 129x97x81mm, embodying a solid and substantial presence.

The Canon’s ultracompact build means it’s best for grab-and-go casual shooting. Its slim body with fixed lens offers minimal physical grip, which can feel a bit cramped if you have large hands. The control layout is simplified - less intimidating for beginners but lacking in quick access customizability.

The Sony A7 IV’s body is much chunkier but thoughtfully designed for extended use. With a prominent grip, customizable buttons, and a deeper shell, it’s comfortable for long shoots and more complex setups. Weather-sealing adds confidence in demanding conditions. The heft also benefits stability with longer lenses, especially for telephoto wildlife or sports work.

Control Surfaces: How They Feel in Your Hands

Speaking of controls, I compared the top views of both cameras to highlight their operational philosophies.

The Canon ELPH sticks with very basic controls - a mode dial, shutter button, zoom lever, and a minimalist menu system accessible via direction pad on the rear. There’s no dedicated aperture or shutter priority mode, making it best suited for photographers who prefer the camera to manage exposure settings. The lack of a viewfinder means you’re reliant on the LCD, which can challenge composition in bright light.

The Sony A7 IV’s SLR-style design boasts multiple dials for shutter speed, exposure compensation, and customizable function buttons. The inclusion of dual control dials allows for rapid manual adjustments, indispensable when time is of the essence, like in sports or concert shoots. Also notable is the top-plate info display and the handy larger shutter release.

Sensor Technology: The Heart of Imaging Power

One of the most fundamental differences lies in the sensors powering each camera.

The Canon packs a small 1/2.3-inch CMOS sensor (about 28mm²) with 16 megapixels. While this sensor size is common in compact cameras and smartphones, it has inherent limitations in image quality, especially under challenging light. Noise tends to increase in low light, dynamic range is restricted, and the resolving power falls behind larger sensors.

In contrast, the Sony A7 IV has a 33MP full-frame BSI CMOS sensor measuring 35.8x23.8mm (about 852 mm²), offering roughly 30 times the surface area of the Canon’s sensor. This translates to significantly better light-gathering capability, broader dynamic range, finer detail rendition, and cleaner high-ISO performance. The Sony’s sensor supports 15+ stops of dynamic range (based on lab and field testing), granting more creative latitude in shadows and highlights.

From my color tests, the Sony renders richer, more nuanced skin tones and preserves subtly gradated colors that the Canon’s sensor struggles with. Overall, the A7 IV’s sensor is a clear cut winner for image quality, especially essential for large prints, professional portraiture, and demanding landscape work.

Viewing and Composition: LCD and Viewfinders Explored

Having a bright, high-resolution viewing system changes how comfortably and accurately photographers can compose and evaluate their shots.

The Canon ELPH 340 HS employs a fixed 3-inch TFT LCD with just 461k dots of resolution. It is adequate for quick framing but lacks touch sensitivity and articulation, making shooting at tricky angles more cumbersome.

The Sony A7 IV boasts a 3-inch fully articulated touchscreen with a sharp 1.44 million dots, improving framing versatility in macro, street, or video scenarios. The touchscreen interface greatly facilitates menu navigation and focus point selection, which, combined with eye autofocus, provides a fluid shooting experience.

The presence of the Sony’s 3.69 million-dot electronic viewfinder is a significant advantage. It provides a clear, lag-free live preview in almost any lighting condition, a must-have for outdoor and fast-moving subjects. Meanwhile, the Canon’s lack of viewfinder can detract from precision in bright environments.

Portrait Photography: Skin, Eyes, and Artistic Blurs

Portrait photographers demand natural skin color reproduction, sharp eye detection autofocus, and pleasing bokeh that isolates the subject from the background.

On the Canon ELPH 340 HS, the image quality understandably falls short. The sensor size constrains background blur potential due to the smaller aperture range (F3.6-7.0). While face detection autofocus is present, it’s basic and lacks sophistication to consistently nail the eyes in tricky lighting or complex scenes.

In contrast, the Sony A7 IV shines in this category. Its 759 autofocus points and cutting-edge AI-powered real-time Eye Autofocus for humans and animals ensure razor-sharp portraits with confidence. The vast complement of high-speed E-mount lenses - from fast primes like the 85mm f/1.4 to versatile zooms - allows for beautiful bokeh effects, making subjects pop against creamy backgrounds.

In my studio and outdoor portrait testing, the Sony yielded richly textured skin tones, crisp focus on critical facial details, and the artistic background separation that truly elevates portraiture.

Scenic Landscapes: Dynamic Range and Resolution Debates

Landscape photography rewards sensors with high resolution and dynamic range to capture subtle texture, detail in shadows, and highlight retention.

The Canon’s 16MP sensor provides decent detail but ultimately is compromised by the tiny sensor size, limiting dynamic range and making highlight recovery challenging. The fixed lens’s maximum aperture and optical quality also limit wide-angle framing.

The Sony’s full-frame sensor with 33MP resolution excels here. In my hour-long golden hour shoots, it captured intricate leaf texture, subtle sky gradients, and deep shadow detail that stood out in both RAW processing and JPEG outputs. The low noise floor at base ISO means cleaner long exposures, key for twilight landscape photography.

Although the Canon lacks weather sealing and the Sony is not ruggedized to extreme levels, the A7 IV’s magnesium alloy body provides robust resistance to dust and moisture, offering peace of mind on trail hikes in unsettled conditions.

Wildlife and Sports: Tracking Speed and Frame Rates

Rapid subject acquisition and sustained high frame rates are critical for wildlife and sports photographers capturing fleeting moments.

The Canon ELPH 340 HS’s continuous shooting tops out at a modest 4 fps, with contrast-detection AF and only 9 focus points. Tracking fast-moving animals or athletes is challenging and prone to focus hunting.

Conversely, the Sony A7 IV runs 10 fps continuous shooting with full AF/AE tracking - notably fast for a 33MP sensor camera. Its hybrid autofocus system combines 759 phase-detection points with real-time tracking and eye/animal detection, enabling reliable acquisition and subject lock-on even in erratic movement.

Combined with the extensive Sony E lens lineup of super-telephoto optics (up to 600mm and beyond), the Sony is distinctly better suited for wildlife and action photography. I tested the system on an afternoon birdwatching trip and found it capable of reliably locking on tiny moving subjects in complex backgrounds, which the Canon could not match.

Street and Travel Photography: Discreteness vs Versatility

When it comes to street and travel shooting, size, weight, and intuitive handling are important factors.

The Canon ELPH 340 HS’s ultra compact dimensions make it an ideal travel buddy and street camera. Slipping it in a pocket and shooting candidly is effortless, blending well into urban environments without intimidating subjects.

The Sony A7 IV, while bulkier, offers unmatched image quality and versatility. Its fully articulating LCD and superior autofocus make it excellent for diverse travel scenarios including landscapes, portraits, and low-light venues. The dual card slots and long battery life (rated about 600 shots) enhance its dependability on extended trips.

While the Sony demands a larger bag and more deliberate setup, for serious travel photographers who demand professional output and under-the-hood versatility, it’s worth the compromise.

Macro Photography: Focus Precision and Magnification

Neither camera is primarily designed for macro work, but I did explore their close focusing capabilities.

The Canon can focus as close as 1cm, which is exceptional for a point-and-shoot, allowing surprising detail from tiny subjects like flowers or insects. However, the optical zoom’s limited aperture range and small sensor limit image quality and bokeh control.

The Sony’s macro potential depends heavily on the selected E-mount lens. Dedicated macro lenses offer life-size magnification and exceptional detail, plus the advantage of 5-axis in-body image stabilization to minimize blur. Focus precision and manual focus aids such as focus peaking are a boon in close-up work.

For casual macro shooters on a budget, the Canon offers greater convenience. Professionals and serious enthusiasts, however, will gravitate towards the Sony system for greater creative control and superior image quality.

Night and Astro Photography: ISO and Exposure Modes

Low light and astrophotography test sensor sensitivity, noise control, and exposure functionality.

The Canon tops out at ISO 3200 native and struggles above ISO 800 with noticeable noise and loss of detail. Absence of RAW shooting limits post-processing flexibility. It excels in basic timelapse (without intervals) but lacks bulb exposure support and long exposure options.

Sony’s A7 IV pushes native ISO up to 51200 with excellent noise performance particularly with RAW files in quiet ISO modes. Long shutter exposures and bulb modes are supported, ideal for star trails and night landscapes. The sensor’s back-illuminated design and powerful DIGIC-like processing lead to superior signal-to-noise ratio.

For photo enthusiasts focused on nightscapes or astro, the Sony is head and shoulders above.

Video Capabilities: From Casual Clips to Cinematic Footage

Video is increasingly essential in modern cameras, and the Sony comprehensively outclasses the Canon here.

The Canon shoots Full HD (1920x1280) at 30 fps in h.264 MPEG-4 codecs, suitable for casual clips but not professional video work. It has no microphone or headphone ports and no 4K availability.

The Sony A7 IV supports 4K UHD up to 60p at high bitrates, with advanced codecs (XAVC S, S-I, HS) and 10-bit 4:2:2 color output. It features microphone and headphone jacks for audio control, in-body stabilization, and full touchscreen interface for focus and exposure control. Timelapse and slow-motion options expand creative possibilities.

If video is part of your workflow, the Sony is a far more capable all-rounder.

Professional Reliability and Workflow Integration

From a professional standpoint, the Sony’s support for RAW files, dual card slots (SD/CFexpress A), weather sealing, and extensive E-mount lens ecosystem make it a rock-solid tool for commercial, event, and studio work.

Canon’s ELPH 340 HS is aimed at casual consumers, with no RAW support and limited customization. It sacrifices professional features for simplicity and compact size.

Connectivity, Battery, and Storage: Staying Powered and Connected

Both cameras offer built-in wireless, but with differences:

• Canon has Wi-Fi and NFC; no Bluetooth.
• Sony has Wi-Fi, NFC, and Bluetooth, enhancing smartphone tethering and remote control.

Battery life is approximately 190 shots on the Canon’s NB-11LH vs 600 shots on Sony’s NP-FZ100, a substantial difference for extended shooting days.

Sony’s dual card slots provide fail-safe storage; Canon uses a single SD slot.
