Canon PowerShot ELPH 340 HS vs. Sigma SD10: An In-Depth Comparison for Your Next Camera

Choosing the right camera can be overwhelming, especially when the options come from very different categories and eras like the Canon PowerShot ELPH 340 HS and the Sigma SD10. One is a compact point-and-shoot designed for convenience and portability, the other a mid-size DSLR focused on serious image quality with an unusual sensor technology. Both cameras serve unique purposes and audiences. Our goal here is to help you understand their capabilities through a hands-on, expert lens, so you can make a confident choice aligned to your photography style and ambitions.

Let’s break down both cameras across their design, technology, and performance attributes. Then we’ll explore how each performs in various photography disciplines before delivering our final recommendations.

First Impressions: Handling and Ergonomics

Since photography is as much about the tactile experience as it is about specs, we start by analyzing their physical design and user interface.

Compact Convenience or DSLR Control?

The Canon ELPH 340 HS is a true ultracompact camera, measuring just 100x58x22 mm and weighing in at a featherlight 147 grams. Its size invites spontaneous shooting and is well-suited for casual outings or travel where minimizing gear is key.

In contrast, the Sigma SD10 is a mid-size DSLR, bulky compared to the Canon, with dimensions of 152x120x79 mm and a heft of 950 grams. This heft supports robust build quality but demands a camera bag and a more deliberate shooting posture.

Control Layout and Intuitiveness

The Canon offers a simple top control layout with minimal buttons, designed for quick point-and-shoot use. Its DIGIC 4+ processor complements the user-friendly interface, though it lacks advanced manual controls you might expect for refined exposure tweaking.

Sigma’s SD10 provides a traditional DSLR experience. The top view reveals dedicated dials for shutter speed, aperture, and modes like shutter priority, aperture priority, and full manual exposure. This affords precise control but comes with a steeper learning curve.

If you value quick access and portability, Canon’s ELPH 340 HS scores high here. For those who want granular creative control, the Sigma SD10's approach is more fitting.

Seeing the World: Sensor and Image Quality

A camera’s heart is its sensor, determining resolution, dynamic range, and color fidelity.

Sensor Size and Type

• Canon ELPH 340 HS: Equipped with a 1/2.3-inch CMOS sensor measuring roughly 6.17x4.55 mm (28.07 mm²)
• Sigma SD10: Features a much larger APS-C sized Foveon X3 CMOS sensor, sized 20.7x13.8 mm (285.66 mm²)

The SD10’s sensor area is over ten times greater, signaling potential for superior detail and dynamic range. However, the Sigma’s Foveon X3 sensor operates differently - capturing full color information at each pixel location via three separate photodiode layers. This promises exceptional color accuracy and sharpness compared to conventional Bayer sensors.

Resolution and Image Output

• Canon: 16-megapixel resolution (4608x3456) with a Bayer sensor and antialiasing filter
• Sigma: 3-megapixel output (2268x1512) but with the Foveon’s layered RGB capture, effective resolution and subjective sharpness often surpass traditional sensors of similar megapixel count.

The Canon caters well to everyday sharing and prints up to moderate sizes, whereas the Sigma demands a workflow that respects its unique image files but can yield highly detailed, print-worthy results for landscape and studio work.

Display and Viewfinder: Framing Your Shots

How you compose and review images is crucial for photographic success.

• Canon ELPH 340 HS: Sports a fixed 3-inch TFT LCD with 461k dots; no viewfinder, so composition relies on the LCD only.
• Sigma SD10: Has a smaller 1.8-inch screen with 130k dots and more importantly, a bright optical pentaprism viewfinder covering 98% of the frame at 0.77x magnification.

If you prefer composing through a viewfinder, especially helpful in bright situations and for precise manual focusing, Sigma excels here. On the other hand, the Canon’s larger screen benefits casual framing and image review but suffers outdoors under direct sunlight.

Lens and Focus Systems: Versatility and Accuracy

Lens Mount and Focal Length

• Canon: Built-in fixed lens with 25–300 mm equivalent zoom (12x), max aperture f/3.6–7.0. Great for travel and all-around shooting without swapping lenses.
• Sigma: Uses Sigma SA lens mount, compatible with 76 lenses ranging from wide-angle to telephoto. This offers enormous creative flexibility but requires investment in lenses.

Autofocus Features

• Canon: Contrast-detection autofocus with 9 focus points, face detection, and continuous autofocus modes. No sophisticated eye or animal detection.
• Sigma: Contrast-detection autofocus only, no face or eye detection. Focus assist via manual focusing supported by the optical viewfinder.

Canon’s autofocus mechanism is more modern and user-friendly for fast casual shooting and portraits. Sigma’s manual focus emphasis aligns with deliberate shooting styles such as studio portraiture or landscapes.

How They Perform in Different Photographic Scenarios

Portrait Photography

Portraits demand accurate skin tones, reliable focus on eyes, and pleasing background separation.

• Canon: Face detection autofocus helps keep subjects sharp. The sensor’s natural color science renders good skin tones. The fixed lens’ limitations mean bokeh quality varies, and max aperture f/3.6–7.0 results in modest background blur, especially at telephoto.
• Sigma: The Foveon sensor’s superb color fidelity and high perceived detail create rich, nuanced portraits. Use of wide-aperture Sigma lenses (like 50mm f/1.4) can achieve stunning bokeh. Manual focus requires skill but rewards with precise control.

Landscape Photography

Landscape shooters prize dynamic range, resolution, and weather resistance.

• Canon: Limited sensor size results in moderate dynamic range; no weather sealing makes the camera less ideal for harsh conditions.
• Sigma: Larger APS-C sensor and Foveon technology yield excellent tonal gradation with vivid colors and naturalistic detail. While lacking environmental sealing, the DSLR build is more robust.

Wildlife and Sports Photography

Fast autofocus and high burst rates are essential here.

• Canon: 4fps continuous shooting supports casual action capture. Contrast-detection autofocus less effective on fast-moving subjects; limited telephoto zoom might restrict reach.
• Sigma: No continuous shooting speed data and manual focus is a bottleneck; not suited for action or wildlife.

Street Photography

Discretion, portability, and low light capability define success.

• Canon: Ultra-compact size makes it easy to carry and shoot unnoticed. Image stabilization and decent max ISO 3200 allow handheld, low-light moments.
• Sigma: Larger, heavier body is more conspicuous. Max ISO 800 limits low-light performance.

Macro Photography

Detail and focusing precision matter.

• Canon: Macro focusing down to 1 cm combined with image stabilization aids handheld close-ups.
• Sigma: Dependent on lens choice for macro; manual focusing can provide fine control but requires practice.

Night and Astro Photography

High ISO performance and sensor noise are critical.

• Canon: Max native ISO 3200 but small sensor leads to significant noise beyond ISO 800.
• Sigma: Max ISO 800 and boost to 1600, coupled with Foveon sensor, produces clean, nuanced images but long exposures rely on tripod and manual controls.

Video Capabilities

• Canon: 1080p video at 30fps, H.264 codec, no external mic input.
• Sigma: No video recording.

For casual video, Canon is the clear winner.

Travel Photography and Portability

Canon’s light weight, zoom versatility, and wireless built-in connectivity make it perfect for travel. Sigma’s size and lens needs hinder spontaneous travel photography.

Professional Workflows

Sigma supports raw file output designed for serious editing workflows; Canon does not. Sigma’s lens mount and manual options suit studio and controlled environment pros. Canon caters more to casual and beginner users.
