Canon PowerShot SX270 HS vs Sigma DP2s: An Expert’s Take on These Two Distinct Compacts

When exploring the world of compact cameras, enthusiasts and professionals alike are often caught between versatile zoomers and fixed-lens precision shooters. Today, I’m diving deep into the Canon PowerShot SX270 HS and the Sigma DP2s - two very different cameras released in relatively close eras but targeting distinct user needs. Having tested thousands of cameras over the years, I’ll share detailed real-world insights, technical know-how, and recommendations to help you decide which might fit your photography style and budget.

Let’s peel back the curtain on these cameras, starting with their core differences and building up from there.

First Impressions: Size, Handling & Ergonomics

When you pick up the Canon SX270 HS and Sigma DP2s side by side, their distinct form factors immediately communicate very different design philosophies.

The SX270 HS is a slim, pocketable superzoom compact with classic rounded edges and a comfortable grip. Measuring just 106 x 63 x 33 mm and tipping the scales at 233 grams, it fits nicely in a jacket pocket or small bag. The ergonomics are user-friendly with well-placed buttons for quick access - even for shooting on the go. This appeals to travel photographers and casual shooters wanting reach without lugging lenses.

On the other hand, the Sigma DP2s feels chunkier and boxier: 113 x 60 x 56 mm, weighing 280 grams. It’s certainly not bulky in an absolute sense, but its rectangular, no-frills design caters to photographers seeking image quality over zoom range. This large-sensor compact feels more deliberate, like a tool you’d use when image fidelity is paramount but don’t want to carry a DSLR. However, the narrower grip can feel a bit cramped during extended shooting sessions.

In an age where many cameras aim to please everyone, these two stick firmly to their camps - one embracing portability and zoom, the other prioritizing sensor size and image quality.

Top-Down Control Layout: Who Wins the Workflow Battle?

Opening up the control scheme and top panel design shows how each camera approaches user interface differently.

The SX270 HS offers several dedicated dials and buttons on the top and back, including a mode dial with all the usual suspects: manual, aperture priority, shutter priority, and several automatic modes. There’s a zoom lever perched on the shutter button and a built-in flash that pops up with ease - important for casual and travel use. It leans toward functional, aiming to give quick access without overwhelming the user.

Sigma DP2s, meanwhile, keeps it minimalist. It lacks a zoom ring (fixed lens), a flip-up flash (flash is built-in, but smaller), and the physical dials are fewer. The lack of an articulating screen might chafe some, but the camera excels in providing manual exposure modes with precision, reflecting its more serious, contemplative shooter angle.

From my testing, if fast, intuitive adjustments are your thing, Canon’s layout wins. Sigma’s is geared toward methodical shooting, where you have fewer variables to tweak in the field.

Sensor Tech and Image Quality: Apples vs. Oranges?

This is where the two cameras diverge most fundamentally. Let’s get technical but accessible.

Canon SX270 HS:

• Sensor: 1/2.3” BSI-CMOS
• Resolution: 12 Megapixels (4000 x 3000 pixels)
• Sensor area: ~28.07 mm²
• Max ISO: 6400 (native)
• Antialias (Low-pass) filter: Yes
• Raw support: No

Sigma DP2s:

• Sensor: APS-C Foveon X3 CMOS (unique layered sensor capturing full RGB at each pixel)
• Resolution: 5 Megapixels (2640 x 1760 pixels) - but effectively higher color resolution due to Foveon tech
• Sensor area: ~285.66 mm² (over 10x larger area than SX270 HS)
• Max ISO: 3200 (native)
• Antialias filter: Yes
• Raw support: Yes

The SX270 HS sports a tiny sensor typical of most bridge cameras, relying on Canon’s DIGIC 6 processor to eke out decent image quality through noise reduction and image sharpening. It captures more pixels than the Sigma, but its sensor size drastically limits dynamic range and low-light performance. The zoom lens (25-500 mm equivalent) adds versatility at the expense of optical compromises inherent in long zoom compact lenses.

The Sigma DP2s features the much larger APS-C sized sensor with the famous Foveon X3 technology - instead of the common Bayer filter with separate red, green, and blue pixels, Foveon layers capture all color info at every pixel site. This provides striking color fidelity, sharpness, and detail rendering unmatched by most fixed-lens compacts, albeit at a lower megapixel count. The fixed 41 mm equivalent f/2.8 lens maximizes sharpness and performance.

If you prize absolute pixel count above all else, Canon offers more pixels. But image quality experts and even many professionals will appreciate the Sigma’s rich color depth, tonality, and superior low noise at base ISO - perfect for portraits, landscapes, or archival work where every nuance counts.

Live View, LCD and EVF Experience

Neither camera sports an electronic viewfinder, though this is no surprise given their era and class. However, rear screen design is an important interface.

The Canon SX270 HS has a bright and clear 3-inch fixed LCD with 461k dots, offering crisp live view framing and playback. Though not touch-enabled, menus are responsive and logical. This makes it friendlier for casual shooters and travel photographers who value quick framing and easy confirmation of shots.

The Sigma DP2s has a smaller 2.5-inch LCD with 230k dots, which is noticeably less detailed and less bright, making composition and review a bit more challenging especially in sunlight. The interface is more utilitarian, favoring manual photographers accustomed to checking focus critically rather than relying on flashy displays.

From a hands-on perspective, the Canon’s screen feels better designed for everyday shooting versatility. The Sigma demands a more focused, deliberate approach with less hand-holding.

Autofocus Systems: Speed, Accuracy and Tracking

AF relevance often depends on shooting style: sports vs still life, for example.

• Canon SX270 HS utilizes contrast detection AF with face detection and continuous autofocus in live view. It offers single, multi-area AF, and face detection technologies. Its autofocus is quick enough for casual wildlife and street photography but can hunt in low light or fast action.

• Sigma DP2s employs contrast detection AF only - no face recognition or tracking. Focus speed is slower and less responsive, particularly because of the older processor and fixed focal length. This camera invites you to slow down and engage in thoughtful manual focus refinement if needed.

In practice, if your priority includes wildlife, sports, or dynamic street shooting, the Canon’s AF system suits better. The Sigma rewards patience and intentional composition but struggles with moving subjects.

Zoom and Lens Ecosystem: Versatility vs. Quality

Canon SX270 HS sports an impressive 20x optical zoom lens ranging from 25 mm wide to 500 mm telephoto equivalent. This is ideal for travelers and nature enthusiasts looking to capture everything from landscapes to distant birds without swapping lenses.

Sigma DP2s ceases zooming in favor of a prime 41 mm equivalent lens with a fixed aperture of f/2.8. This limitation is by design, concentrating on optical quality rather than zoom reach. Manual focus and lack of image stabilization require a sturdy shooting style.

If you want a "one camera-does-all" with flexibility, Canon wins hands down. But if you value sharpness, minimal distortion, and artistic control - and are willing to work within a 41 mm field - Sigma’s prime lens is compelling.

Burst Shooting, Shutter Speeds, and Timeliness

For those shooting sports or wildlife, frame rate and shutter options matter.

• Canon SX270 HS offers continuous shooting at 4 fps and shutter speeds between 15s and 1/3200s, providing decent coverage for most casual action shots.

• Sigma DP2s is limited to 3 fps max burst with shutter speeds from 15s to 1/2000s, slower compared to Canon, and no continuous AF during bursts.

For fast-paced scenarios, Canon’s higher frame rate and faster shutter options add value. Sigma is a slower performer meant for deliberate framing.

Video Capabilities: Moving Pictures Factor

• Canon SX270 HS records Full HD 1080p video at up to 60 fps with stereo sound and MPEG-4/H.264 codec, including optical image stabilization for smoother footage. It lacks microphone and headphone ports, but HDMI output is included.

• Sigma DP2s has very limited video, with max resolution at 320x240 pixels in Motion JPEG format - practically toy camera quality by today’s standards. It’s clear this is primarily a stills camera.

For content creators wanting solid HD video, Canon is the far better choice, while Sigma’s strengths lie strictly in still photography.

Battery Life and Storage Flexibility

• Canon SX270 HS uses the NB-6L proprietary battery, rated for about 210 shots per charge - a bit lean by modern standards, but understandable for a budget compact.

• Sigma DP2s battery life is unspecified but traditionally Foveon cameras are power-hungry, often needing spare batteries. Storage is compatible with SD/SDHC/SDXC for Canon, and SD/SDHC/MMC for Sigma.

If you’re making long trips or extended shoots, bring extras for either but especially the Sigma.

Durability and Build Quality: Weather Sealing and Toughness

Neither camera offers weather sealing or rugged construction. Both are compact, plastic-bodied units targeting casual use rather than pro-level environmental resistance.
