Canon PowerShot S100 vs Sony Cyber-shot DSC-W620: A Compact Camera Shootout from an Experienced Photographer’s Lens

Choosing between two compact cameras - especially ones from back in the early 2010s like the Canon PowerShot S100 and the Sony Cyber-shot DSC-W620 - can feel a bit like stepping into a time machine. These cameras hail from an era before smartphones completely dominated casual snapping, offering distinctive features for enthusiasts seeking pocketable companions without compromising too much on image quality.

Having spent over 15 years testing thousands of cameras, including vintage compacts just like these, I’m excited to compare the Canon S100 and the Sony W620 in a way that matters - not just dry specs, but how these cameras perform when shoved into the trenches of real-world photography. We’ll discuss their internals, handling, image quality, and how they suit different photographic styles, from portraiture to wildlife, landscapes to low light - yes, even compact cameras get to play in that sandbox.

Ready? Let’s unpack these two contenders with a critical but fair eye.

One Size Doesn’t Fit All: Handling and Ergonomics

Before poking the sensors, the first tactile impression matters. How a camera feels in hand is crucial for long shooting sessions or quick grabs. The Canon S100 comes in at 99 x 60 x 28 mm and weighs roughly 198g, while the Sony W620 is slightly smaller and lighter at 98 x 56 x 20 mm and 116g.

That chunkier build of the S100 translates into more grip comfort and sturdier buttons. Canon’s reputation for ergonomics shows here with clearly defined dials and a satisfying shutter button arc - no fumbling when quick reactions count. Meanwhile, the Sony opts for a sleeker, more pocket-friendly silhouette, which makes it easier to carry but sacrifices a bit of tactile security. For street photographers or casual travelers who prioritize minimalism, the W620’s weight and size might be a draw.

Peeking at the cameras from the top reveals more control philosophy differences:

The Canon boasts dedicated exposure control knobs (shutter priority, aperture priority, manual modes), while Sony’s W620 keeps things simpler - no manual exposure modes or dedicated dials, which may irk enthusiasts craving control. However, Sony’s “Easy Mode” interface may appeal to beginners looking for straightforward shooting without diving into complex menus.

Verdict on handling: If button layout and physical controls fuel your photographic passion - manual shooting, quick access to functions - the Canon S100’s tactile design feels like home. For snap-and-go convenience and lightweight pockets, Sony’s smaller, minimalist W620 shines.

The Heart of the Battle: Sensor Technology and Image Quality

Let’s talk about image quality because, after all, what good is a camera if the photos don’t impress?

The Canon S100 employs a 1/1.7-inch CMOS sensor with 12 megapixels, while the Sony W620 sports a smaller 1/2.3-inch CCD sensor with 14 megapixels. Both carry an anti-aliasing filter, which slightly softens detail but reduces moiré patterns. The Canon’s sensor size measures approximately 7.44 x 5.58 mm (around 41.52 mm²), compared to Sony’s smaller 6.17 x 4.55 mm (28.07 mm²) sensor area.

This difference in sensor real estate has profound implications. The larger Canon sensor inherently captures more light, which generally translates to superior dynamic range, better low-light performance, and richer color depth. DxOMark’s testing reflects this, giving the Canon S100 an overall score of 50 - solid for a compact - and respectable color depth (20.7 bits) and dynamic range (11.6 EV). Sony’s W620, unfortunately, was not tested by DxOMark, but based on sensor type and size, it can’t quite match Canon’s imaging prowess.

Practically, this means that Canon’s photos show more detail in shadows and highlights, especially useful in landscape scenes where subtle tonal gradients define the mood. Additionally, its CMOS sensor enables faster readouts, aiding autofocus and video performance.

Sony’s CCD sensor, despite packing higher megapixels on a smaller chip (14MP), tends to struggle more with noise at higher ISOs. Speaking of resolution, the Sony’s max image size stands at 4320 x 3240 pixels, a modest bump over Canon’s 4000 x 3000. However, the pixel pitch’s smaller size in Sony results in less light gathered per pixel - another tradeoff against the perceived megapixel advantage.

Living with the Screen and UI: Your Window to the World

We interact with our cameras mostly through the LCD screen - it’s our digital playground and image review station.

Canon S100 offers a 3-inch fixed LCD screen at 461k dots resolution. Sony’s W620 sports a slightly smaller 2.7-inch Clear Photo TFT LCD with 230k dots resolution.

There’s no contest on sharpness: Canon’s screen provides crisper image previews, making it easier to gauge focus accuracy and evaluate exposure on the fly. Sony’s screen feels a bit fuzzy in comparison, reducing confidence when critical focus and detail evaluation are required.

Neither camera has touchscreen capabilities or an electronic viewfinder, which in 2011-2012 wasn’t unusual. However, the S100’s superior live view performance paired with better manual control integration makes framing and setting adjustments less frustrating.

In day-to-day shooting, I found the S100’s interface more responsive and logically arranged, which reduced fumbling through menus, a non-trivial benefit for those who prefer fast shooting.

From Portraits to Street: A Discipline-by-Discipline Look

How do these cameras serve the wide spectrum of photography disciplines? Let’s explore.

Portrait Photography

Portrait work demands nuanced skin tone reproduction, smooth bokeh, and reliable eye detection focus.

Canon S100 includes a fast, bright F2.0 aperture at the wide end (24mm equiv.) which helps isolate subjects with pleasant background blur, unusual for compacts at the time. Its 9 autofocus points (including face detection) deliver precise focusing, and the DIGIC 5 processor enhances color rendering - skin tones appear warm but natural, resisting the “plastic” look sometimes found in compact cameras.

Sony W620’s lens maxes out at F3.2, slower than Canon’s, thus less control over depth of field. Autofocus is simpler and limited, though still equipped with face detection. Portraits look sharp but with less three-dimensional pop and background separation, especially indoors or in tight spaces.

Landscape Photography

Landscape shooters benefit from dynamic range and resolution.

Canon’s larger sensor and better dynamic range (11.6 EV) capture a broader tonal spectrum in scenes with strong shadows and highlights, from sunlit peaks to shaded valleys. This contributes to rich, detailed imagery with more post-processing latitude.

Sony’s smaller sensor and CCD design deliver flatter images with less detail retention in shadows. The W620’s max ISO tops at 3200, but noise becomes intrusive beyond ISO 400–800.

Also notable is the Canon’s GPS, handy for geo-tagging landscape shots - a subtle but useful feature for organized portfolios or nature documentation.

Wildlife and Sports

Both cameras are limited by their compact nature for action photography, but let’s see what they offer.

Canon S100 shoots at 2 fps continuous mode, somewhat slow but better than Sony’s 1 fps. Autofocus is contrast-detection only, but Canon’s superior processor aids quicker acquisition and tracking. A bright F2.0 aperture helps in low light, although the lens’s telephoto reach maxes at 120mm equivalent - modest for wildlife.

Sony’s 140mm telephoto reach is slightly longer, good for distant subjects, but hindered by a slower aperture (F6.5 at tele) and slower autofocus. Continuous shooting is limited, and image review lag disrupts quick framing.

Overall, neither is a dedicated sports or wildlife camera, but Canon has a slight edge for shutter responsiveness and sharpness.

Street Photography

Stealth and quick access define street shooting.

Sony’s smaller, lighter W620 is more discrete and quicker from pocket to shoot. It’s less intimidating in social settings, a plus for candid shots. The S100, with its chunkier ergonomic grip, is more obtrusive, but the improved control and image quality arguably payoff.

Low-light capabilities favor Canon again, permitting handheld shots in ambient light without resorting excessively to flash.

Macro Photography

Canon’s 3cm macro focus range is impressive for compacts, enabling detailed close-ups with good subject isolation. Its optical image stabilization aids in handheld macro shooting, reducing blur from tiny hand shakes.

Sony’s macro range at 5cm is less aggressive, requiring more distance and thus less magnification. Lack of optical image stabilization means macro shots may need more care or tripods.

Night and Astro Photography

This is where sensor technology truly matters.

Canon’s combination of larger sensor, CMOS technology, optical image stabilization, and manual exposure modes opens possibilities for handheld night photography and even basic astrophotography. Although limits exist due to the small sensor size, its max ISO 6400 and 15-second shutter speed slightly trumps Sony.

Sony W620’s max shutter speed is 1/1600s minimum and longer exposures max out at 2 seconds - not ideal for night or astrophotography. The lack of manual exposure modes hinders creative night shooting.

Video Performance

Canon S100 records Full HD 1080p at 24 fps using efficient H.264 compression, and offers HD 720p at 30 fps. Optical image stabilization extends into video, resulting in smoother footage.

Sony W620 is limited to 720p HD at 30 fps and lower resolutions, with Motion JPEG format - a less efficient codec producing larger files and reduced quality.

Neither camera supports external microphones or headphone jacks, but Canon’s HDMI port allows easy playback and connection to external monitors.

The Nuts and Bolts: Build, Battery, and Connectivity

Beyond shutter clicks, these aspects impact your shooting experience.

Neither camera is weather sealed, which is a bit disappointing but expected at their price points.

The Canon S100’s build feels solid with robust button clicks and dials, while Sony’s W620 uses lighter plastic, reflecting its budget orientation.

Battery life is close: Canon rated at 200 shots per charge versus Sony’s slightly better 220 shots. However, Canon’s NB-5L battery is a bit bulkier and more expensive than Sony’s NP-BN.

Both cameras support Eye-Fi wireless SD cards for photo transfer, but lack Bluetooth or NFC for modern instant sharing. Canon has built-in GPS, a nifty bonus for travel photographers; Sony has none.

Lens Characteristics and Compatibility

Both cameras have fixed lenses, so versatility depends solely on built-in zoom ranges and aperture.

Canon S100: 24-120mm equivalent, with a bright F2.0 at wide end tapering to F5.9 telephoto.

Sony W620: 28-140mm equivalent, aperture starting at F3.2, reaching F6.5 at telephoto.

Canon prioritizes optical quality, with a slightly wider wide-angle and faster aperture enabling creative depth-of-field control. Sony extends zoom length modestly but sacrifices aperture speed, impacting low-light and bokeh potential.
