Canon SX700 HS vs Sigma DP2x: A Deep Dive into Two Compact Camera Titans

Choosing a compact camera that fits your photography needs is never as straightforward as picking the flashiest spec sheet. Having tested thousands of cameras over my 15+ years in the field, I can say the devil is very much in the details - how a camera performs under real conditions, how it feels in your hands, and whether its image quality matches your creative demands. Today, we’re putting the Canon PowerShot SX700 HS head-to-head with the Sigma DP2x: two compact cameras from very different eras and philosophies.

One’s a superzoom powerhouse from 2014 with versatility built in, the other a more niche, large-sensor compact from 2011 famed for its image quality but less fluid in operation. Let’s peel back the layers and see where each shines, where compromises lie, and who each camera really suits. I’m drawing on hands-on testing, lab metrics, and plenty of field use to help you navigate this somewhat unusual pairing.

First Impressions and Handling: Size Isn’t Everything, But It Matters

Right off the bat, the Canon SX700 HS feels familiar and friendly as a compact superzoom. It’s slim, pocketable, weighing just 269g, with a clean, straightforward interface. Its physical dimensions - 113x66x35mm - make it very manageable for travel and everyday shooting.

The Sigma DP2x, slightly heavier at 280g and chunkier with a depth of 56mm, presents itself as a more solid, almost deliberate tool. It’s a large-sensor compact aiming to deliver DSLR-like image quality without the size baggage. Yet, the heft and deeper grip hint that this camera wants to be held deliberately, inviting slower, more considered shooting.

Handling differences are clear when you compare their top controls and viewfinders - or more precisely, their lack thereof. Neither has an electronic viewfinder, relying solely on rear LCDs (more on those shortly). The Canon features a broader focal range with easy-to-access zoom, exposure modes, and an array of buttons catering to quick manual overrides, while the Sigma's minimal control layout feels more barebones, befitting a camera that’s less snap-and-go and more methodical.

Ergonomically, Canon’s shines for casual users and enthusiasts who juggle spontaneity with some manual control, while the Sigma demands you slow down and engage fully with exposure settings.

Sensor Technology and Image Quality: Small Sensor Versatility vs. Large Sensor Purity

You can’t talk about these two cameras without addressing their giant difference in sensor technology, as that cements their fundamental imaging philosophies.

The Canon SX700 HS sports a 1/2.3” BSI-CMOS sensor measuring 6.17x4.55mm, packing in 16 megapixels. This sensor size is typical for compact superzooms and optimized for maximizing zoom range. However, its physical area is only 28.07 mm², which imposes inherent limits on image quality, especially in low light and dynamic range.

The Sigma DP2x employs a much larger APS-C-sized CMOS (Foveon X3) sensor of 20.7x13.8mm and a total surface area of 285.66 mm² - over 10 times the area of the Canon’s sensor. The Foveon X3 design layers color information differently, capturing full color at every pixel site, often revered for its color fidelity and sharpness even if megapixel count lags at 5MP.

From my testing, the Sigma’s sensor delivers superior color depth, smoother gradations, and far less noise at base ISOs compared to the Canon’s much smaller sensor, though it lacks the latter’s pixel resolution advantage. It’s a classic trade-off: Canon’s high megapixels enable bigger prints and more cropping flexibility, while Sigma’s sensor produces images with richer detail per pixel and arguably better tonal rendition.

Low-light performance also favors the Sigma in terms of image integrity, with less unexpectedly aggressive noise reduction. But note that the Sigma's limited dynamic range and slower sensor readout mean it’s less forgiving in harsh lighting.

LCD Screens and User Interface: Reviewing Your Shots and Making Adjustments

Both cameras eschew electronic viewfinders, pushing you to rely on the back LCD for framing and reviewing images. The Canon’s 3-inch fixed PureColor II G TFT screen sports a higher resolution of 922k dots, offering a crisp and clear preview, even in moderate ambient light.

In contrast, the Sigma DP2x’s screen is smaller at 2.5 inches with a paltry 230k dots resolution, which feels outdated and is tough to use in bright conditions - obviously a product of its era but frustratingly limited.

This difference is crucial. Especially for street and travel photography, where quick composition and instant feedback are vital, the Canon’s LCD lends itself better to a smooth user experience. Sigma users need to rely on histogram checks and careful exposure confirmation to avoid surprises.

Though neither camera sports touchscreens, both offer full manual exposure controls and live view focusing, but the Canon’s interface is more intuitive for those less technical, while Sigma invites dedicated photographers who don’t mind fiddling with settings.

Zoom Lenses vs. Fixed Focal Length: Which Approach Fits Your Style?

Another major distinction is the lens design philosophy. Canon’s SX700 HS features a versatile 30x optical zoom lens covering 25-750mm equivalent focal length at apertures ranging from f/3.2 to f/6.9. This kind of reach accommodates a wide spectrum of photography - landscapes to wildlife. The built-in optical image stabilization helps manage the inevitable shake at long focal lengths.

On the flip side, the Sigma DP2x is fixed at a 41mm equivalent prime lens (with an f/2.8 maximum aperture). This focal length sits nicely in the classic “standard” range, which encourages composing mid-range, naturally framed shots with rich background separation.

Prime lenses like the Sigma’s have fewer optical compromises, delivering superior sharpness and lower distortion - attributes I verified in my resolution charts and in-field use. However, you lose versatility - no telephoto zoom or wide-angle options here.

If you’re shooting travel, everyday snapshots, or wildlife, the Canon SX700 HS’s zoom lens is a clear winner for flexibility. But if you prefer deliberate portrait, street, or landscape composition with a fixed lens, the Sigma DP2x lens excels in image quality.

Autofocus Systems: Speed, Accuracy, and Usability

In real-world shooting, autofocus performance greatly affects keep rates.

The Canon SX700 HS employs a 9-point contrast-detection AF system with face detection and continuous AF modes. I found that it locks focus quickly in good light and tracks faces reasonably well for a compact, letting you shoot fast-moving subjects or snapshots without much fuss. However, it lacks more advanced tracking or phase-detection capabilities, meaning it struggles under low light or with erratic subjects.

Conversely, the Sigma DP2x uses a contrast-detection AF system with a single area focus, no face or tracking modes, and only single AF - meaning you have to wait for focus confirmation between shots. This slower focusing means burst shooting is limited to 3 fps, and moving subjects present a challenge. For studio or landscape use, this is less critical, but for events or wildlife, it slows you down.

Burst Shooting and Continuous Performance

Photographers interested in fast action - sports, wildlife - will be interested to know the Canon SX700 HS boasts a continuous shooting rate of 9 fps, impressive for the category. This allows you to capture fleeting moments effectively.

The Sigma DP2x’s burst rate is slower at about 3 fps, reinforcing its role as a deliberative shooter’s tool - great for portraits, landscapes but not suited to fast action.

Flash and Low-Light Shooting

Canon includes a built-in flash with a 3.5-meter effective range and multiple flash modes, including slow sync. External flash support is absent here, which might frustrate dedicated flash users.

Sigma offers a slightly longer flash range at 4.3 meters, plus forced flash, red-eye reduction, and slow sync. Moreover, it supports external flashes - a plus for studio work or low-light photography where you want more control.

Both cameras struggle in extreme low light due to sensor size and ISO limits - the Canon maxes at ISO 3200, sufficient for casual use but noisy at best. Sigma also caps at 3200 ISO but does so with less noise due to the Foveon sensor’s unique structure, though at the expense of reduced convenience (slow AF, slow shutter speeds).

Macro Photography: Up Close and Personal

The Canon SX700 HS surprises with its macro capabilities, offering focusing as close as 1 cm on the short end of the zoom - a boon for close-up detail shots of flowers or insects without accessory lenses.

The Sigma DP2x lacks formal macro capability, focusing mostly on its prime lens’ capabilities. For serious macro photographers, Canon’s flexibility wins here.

Video Capabilities: How Do They Stack Up?

For casual video work, Canon’s SX700 HS provides Full HD recording at 60p and 30p with H.264 compression. It uses optical stabilization to smooth out handheld footage, but lacks external mic or headphone jacks - limiting professional audio capture.

The Sigma DP2x’s video options are extremely limited: only 320x240 resolution Motion JPEG video is possible, archaic by today’s standard.

If video is important to you - even casual vlogging or family footage - Canon’s SX700 HS is clearly better suited here.

Battery Life and Connectivity: Keeping You Shooting Longer

Canon uses an NB-6LH battery rated for 250 shots per charge, which matches similar bridge cameras. It supports SD, SDHC, and SDXC cards and features built-in Wi-Fi and NFC for quick image transfer - a big plus in modern workflows.

The Sigma DP2x’s battery life isn’t specified officially, but my tests showed it to be average, partly due to the lack of wireless connectivity and small screen. It supports SD, SDHC, and MMC cards but offers no built-in Wi-Fi or Bluetooth, limiting immediacy in sharing images.

Price-to-Performance and Value Assessment

When you factor price, Canon SX700 HS launches at $349 new (though prices vary now), offering an all-around well-rounded, user-friendly superzoom experience at a very accessible level.

Sigma DP2x looks pricier at $699, reflecting its image quality niche and APS-C sensor tech. For photographers prioritizing ultimate image fidelity within a compact form factor, Sigma commands premium positioning - albeit with compromises in speed, usability, and versatility.
