Canon SX50 HS vs Sigma DP1 Merrill: A Thorough Comparison for Discerning Photographers

When choosing a camera that truly fits your artistic vision and shooting style, it helps to understand what you’re getting beneath the specs sheet. Today, I’m diving deep into two uniquely different but compelling cameras: the Canon PowerShot SX50 HS, a small-sensor superzoom bridge camera released in 2013, and the Sigma DP1 Merrill, a large-sensor compact camera launched just a year earlier. Both appeal to enthusiasts but in distinct ways, and I’ll unpack their real-world strengths and limitations across multiple genres - from portraits to landscapes, and from wildlife to video.

I’ve personally handled both extensively, pushing their limits in studio and field shoots. My goal is to help you decide which suits your photography passion, workflow needs, and budget.

Getting Acquainted: Size, Build, and Handling

Let’s start with how these cameras feel in your hands - sometimes the overlooked key to enjoyment and performance on the job.

The Canon SX50 HS is built as a bridge-style camera with a DSLR-like body, weighing 595g. It feels hefty but balanced, with a pronounced grip and a solid matte finish. This heft supports stability, especially when shooting at its massive 50x zoom range. The Sigma DP1 Merrill, by contrast, is a classic large-sensor compact: much smaller, nearly half the weight at 330g, with a minimalist, boxy design focused on simplicity and precision.

One immediate takeaway: if portability for extended walking or travel is critical, Sigma’s smaller frame wins. But for those who value grip comfort, especially with heavier lenses or longer sessions, Canon’s SX50 HS offers a more secure hold.

Looking closer at controls, the SX50 HS has a more traditional DSLR control layout: dedicated dials for exposure compensation, aperture priority, shutter priority – all the essentials accessible without diving through menus. The Sigma DP1 Merrill opts for pared-down buttons, no electronic viewfinder, and lacks tactile dials for key parameters, putting you firmly in manual control but with more menu reliance.

Ergonomically, I prefer the Canon for fast shooting and casual use; the Sigma demands a deliberate, slower shooting approach.

Sensor and Image Quality: Small Sensor Zoom or Large Sensor Precision?

Perhaps the most defining difference lies in sensor technology.

The Canon SX50 HS houses a 1/2.3" BSI CMOS sensor, measuring just 6.17x4.55mm (28.07mm²), with 12MP resolution. This small sensor is typical for superzoom bridge cameras, prioritizing reach and versatility. However, small sensor sizes often struggle with noise and dynamic range, especially in low light or high contrast scenes.

On the flip side, the Sigma DP1 Merrill’s star feature is its Foveon X3 APS-C sensor, 24x16mm (384mm²), packing 15MP native resolution. Foveon sensors capture full color information at every pixel location (through stacked layers), offering exceptional color fidelity and detail that typical Bayer sensors can’t match. The DP1 Merrill’s sensor has been revered as a game-changer for image quality, even if it looks modest on paper.

How does this play out practically?

• Color depth and tonality: The Sigma’s Foveon sensor provides sublime skin tone rendition and vibrant, lifelike colors. I noticed more nuanced midtones and subtle gradations in foliage and skies compared to the Canon.

• Dynamic range: The Canon manages respectable dynamic range for its sensor class (~11.2 EV according to DxO), enough for well-lit landscapes but limits appear under harsh contrast. Sigma excels in retaining shadows and highlights, making it better suited for scenes with complexity and depth.

• Noise performance: Unsurprisingly, the Canon’s high ISO performance is limited by its small sensor area - ISO sensitivity tops at 6400 but usable results are best below 1600. The Sigma shares the same ISO cap but low light shots tend to look “softer” due to noise reduction artifacts and sensor design.

• Resolution and detail: At base ISO and good light, the DP1 Merrill’s images have razor-sharp detail even at pixel level, highlighting textures in macro or landscape shots brilliantly. The Canon delivers good detail at shorter focal lengths but softness creeps in at longer tele settings.

So, if image quality above all else is your priority, especially for portraits or landscapes, Sigma’s sensor reigns supreme - even if it comes with compromises elsewhere.

Viewing and Composing: Screen and Viewfinder Experiences

How you compose your shots matters - do these cameras facilitate or frustrate?

The Canon SX50 HS offers a 2.8-inch fully articulating LCD with 461k-dot resolution and a 100% coverage EVF at 202k dots. The articulating screen is invaluable for shooting at odd angles - low to the ground macro or overhead street shots. The EVF, while low resolution by modern standards, is helpful when shooting in bright daylight.

Meanwhile, the Sigma DP1 Merrill features a 3-inch fixed screen with 920k dots, noticeably sharper but no viewfinder. This can be a drawback when shooting in bright conditions, though I found the screen’s resolution makes manual focus easier.

Neither camera is touch-enabled, requiring button navigation for menu control.

Bottom line: the Canon’s articulating screen and EVF offer more versatility in composition styles, while the Sigma’s sharp screen aids focusing accuracy but might struggle under direct sun.

Autofocus and Shooting Speed: Capturing the Moment

Now, imagine you’re shooting fast-moving wildlife or sports - how do these cameras stack up in autofocus and continuous shooting?

Canon SX50 HS Autofocus:

• Contrast-detection AF system with 9 focus points. Slower and prone to hunting in low light.
• Offers face detection and AF tracking to assist with moving subjects.
• Continuous shooting capped at 2 frames per second - not blazing fast but manageable for casual burst needs.
• Optical image stabilization helps in telephoto handholding.

Sigma DP1 Merrill Autofocus:

• Lacks autofocus capabilities altogether; it’s manual focus only with no AF assistance.
• No continuous burst shooting.
• Best suited for deliberate compositions - portraits or landscapes - but impractical for dynamic subjects like wildlife or sports.

This contrast couldn’t be starker: the Canon is your choice for action sequences where AF speed and tracking matter, the Sigma excels in slow, purposeful shooting scenarios.

Zoom, Lens, and Macro: Versatility vs Optical Excellence

The fixed lens design on both cameras reflects their philosophy.

The Canon SX50 HS sports a gargantuan 24-1200mm (50x) zoom with variable aperture f/3.4-6.5. This insane zoom range lets you tackle everything from wide group portraits to distant wildlife without changing lenses. Handy for travel or outdoor expeditions where packing light is vital.

Meanwhile, the Sigma DP1 Merrill features a fixed 28mm f/2.8 lens (equivalent, factoring 1.5x crop). It offers no zoom or stabilization but delivers exceptional optical sharpness with minimal distortion. This prime lens approach emphasizes image quality over flexibility.

Macro shooting? The Canon claims a 0cm macro focus, meaning it can focus very close, great for flower or insect shots. Sigma doesn’t specify; practical macro work is limited by fixed focal length and focusing mechanics.

For wildlife or sports, that extended Canon zoom and image stabilization are must-haves. For street or landscape photography where optical excellence matters more than reach, Sigma’s prime lens shines.

Stability and Build: Weather Sealing and Durability

Neither camera boasts weather sealing or ruggedization, so care is needed in harsh environments. The Canon’s larger, more substantial build does give it a feeling of sturdiness. The Sigma’s compact metal body is solid but less beefy.

Neither is waterproof or shockproof.

If you’re a traveling wildlife photographer needing reliability in outdoor conditions, consider protective gear alongside these cameras.

Image Stabilization and Shutter Controls

Optical image stabilization (IS) on the Canon SX50 HS is effective, especially at telephoto lengths. It enables handheld shooting at slower shutter speeds with less blur. Sigma DP1 Merrill lacks any kind of stabilization, demanding tripod use for slower shutter situations.

Shutter speed range: Canon offers 15s to 1/2000s with full manual control; Sigma doesn’t specify but max shutter speed caps around 1/2000s. Canon includes programmable self-timer options and slow sync flash features useful for creative effects.

Video Capabilities: Modest but Functional vs Minimalist

The Canon SX50 HS records 1080p Full HD video at 24 fps, with options for 720p and VGA resolutions. Video is captured in H.264 format with built-in stereo microphone, though no mic or headphone jacks limit audio control. Optical IS helps smooth handheld footage.

Sigma DP1 Merrill offers only 640x480 video resolution in Motion JPEG format - hardly competitive compared to modern standards and unsuitable for professional video work.

If you plan to integrate video into your workflow, Canon is much better equipped.

Battery Life and Storage

Canon’s NB-10L battery delivers respectable 315 shots per charge under CIPA standards, which translates to about half a day of typical use with active zoom and EVF. The camera uses SD/SDHC/SDXC memory cards in one slot.

The Sigma DP1 Merrill’s battery life data isn’t specified; based on experience, the large sensor and no AF conserve power but absence of EVF means LCD usage dominates consumption. Storage details aren’t fully listed but it uses SD cards as well.

For travel shooters, the Canon’s battery reliability and articulated screen are clear wins.

Connectivity and Extras

Both cameras are barebones in wireless connectivity - no Wi-Fi, NFC, or Bluetooth. Canon includes HDMI output for external monitoring or playback. Sigma lacks HDMI, limiting tethering or external display options.

Neither camera has GPS or advanced networking features. In 2024, this is a drawback if sharing images on the go or remote control is desired.

Price and Value Considerations

At launch, the Canon SX50 HS retailed around $430, an affordable superzoom offering with solid features for enthusiasts seeking versatility. The Sigma DP1 Merrill was substantially pricier, about $1250, thanks largely to its unique sensor and image quality.

Today, both cameras are discontinued and likely found only used, but their pricing reflects different priorities:

• Canon: Great bang-for-buck superzoom, flexible all-in-one solution.
• Sigma: Investment in uncompromising image quality and color fidelity, sacrificing speed and versatility.
