While both cameras belong to the small sensor compact category with fixed lenses and share the common heritage of early 2010s manufacturing, they cater to distinct user profiles and photographic priorities.

In this detailed review, drawing on years of professional hands-on testing experience with hundreds of cameras, I will dissect these two models across sensor technology, ergonomics, optics, and core photography use cases, ultimately providing clear recommendations for enthusiasts and professionals alike. This objective comparison will help you realistically assess which camera better fits your photographic ambitions.

Understanding the Physical Design and Ergonomics

Ergonomics profoundly affect shooting comfort and operational efficiency, especially in portable cameras meant for travel or street use. Despite similar compact classifications, the Canon A3400 IS and Panasonic S1 show subtle differences in size, weight, and control layout that may impact prolonged handling.

The Canon A3400 IS measures approximately 94x56x21 mm and weighs about 126 grams including battery - light and pocketable. In contrast, the Panasonic S1 is slightly larger at 99x59x21 mm but lighter, tipping the scales at 117 grams. This marginal difference suggests both cameras achieve a balance between portability and usable grip, though Canon’s slightly slimmer profile may appeal to users with a high priority on discrete street photography.

A detailed top-down view reveals further nuances:

The Canon construction favors a sleeker, minimalist button design with touch-sensitive LCD controls, whereas Panasonic implements a traditional button interface without touchscreen capabilities. The Canon’s touchscreen may ease menu navigation for casual users, but lacks in tactile feedback preferred by some professionals during rapid manual adjustments.

Both lack electronic or optical viewfinders and rely on rear-screen composing. This design decision aligns with their entry-level, travel-friendly intentions but may frustrate photographers in bright outdoor scenarios where screen reflections challenge visibility.

Sensor and Image Quality: The Heart of the Matter

Sensor performance underpins every photograph’s technical fidelity - resolution, dynamic range, noise handling, and color depth are all sensor-dependent. Both cameras ingest images through 1/2.3-inch CCD sensors, a common standard in compact cameras of their era but now considered modest compared to larger sensor formats.

• Resolution & Dimensions: The Canon A3400 IS’s 16 MP sensor offers 4608x3456 pixels with sensor dimensions of 6.17 x 4.55 mm. The Panasonic S1, meanwhile, employs a slightly smaller sensor area (6.08 x 4.56 mm) with 12 MP resolution producing 4000x3000 pixel images.

• Sensor Type and Image Processing: Both utilize CCD tech rather than CMOS sensors, which limits their high ISO performance and speed but generally provides good color accuracy and fine details in well-lit conditions. Panasonic’s Venus Engine IV processor supports the S1 but, given the sensor, expect moderate noise reduction capabilities.

• Sensitivity Ranges: Canon caps its ISO range at a native 1600, whereas Panasonic’s goes up to 6400 native, theoretically boosting low-light usability but with trade-offs in noise and image quality. Neither camera offers RAW support, limiting post-processing flexibility.

In practical testing under controlled lighting, the Canon’s higher resolution yields more detailed images at base ISO, but the Panasonic arguably delivers smoother tones with lower noise at elevated ISO values around 800-1600, beneficial for indoor or evening shooting scenarios. Both cameras perform acceptably only up to ISO 400-800 before image quality degrades noticeably.

Screens and User Interfaces: Real-World Usability

Without a viewfinder, rear LCD screens become the primary interface for framing, reviewing images, and menu navigation. The quality and usability of the screen impact shooting ease in various environments.

Canon’s 3-inch touchscreen on the A3400 IS offers 230k-dot resolution. The touchscreen functionality allows quick tapping to focus or change settings, benefiting beginners or casual shooters operative mostly at arm’s length. However, the touchscreen sensitivity can lead to unintended inputs, and the low resolution constrains clarity when reviewing fine focus details.

Panasonic’s DMC-S1 features a slightly smaller 2.7-inch 230k-dot TFT LCD without touchscreen. This traditional interface might slow workflow somewhat but reduces accidental menu changes. The screen's fixed position limits flexible framing angles but both cameras share this limitation.

In bright sunlight, neither screen offers exceptional visibility, compelling some photographers to seek shade or rely on the camera’s backlight.

Lens Optics and Focal Range: Versatile but Modest

The fixed-lens design is a natural trade-off in compact cameras, prioritizing lightweight portability and simplified operation, but limiting the optical versatility.

• Canon PowerShot A3400 IS: Equipped with a 28-140 mm equivalent zoom (5× optical zoom) lens with variable aperture F2.8-6.9. The fast wide aperture benefits indoor, low-light, or portraiture scenarios, while its 5x zoom covers moderate telephoto needs for casual wildlife and street.

• Panasonic Lumix DMC-S1: Features a slightly shorter zoom range 28-112 mm equivalent (4× optical zoom) with aperture F3.1-5.6. The lens is a touch slower, reducing low-light flexibility but sufficient for general-purpose photography.

The Canon’s wider maximum aperture at wide-angle can result in better subject-background separation, aiding portrait photographers seeking pleasing bokeh. However, the narrower aperture at telephoto on both cameras limits shallow depth of field effects.

Macro capabilities are also a consideration: Canon’s minimum focus distance is about 3 cm, Panasonic’s 5 cm, giving the Canon a slight edge for extreme close-ups, though neither camera is optimized for macro enthusiasts.

Autofocus Systems: Speed and Accuracy in Focus

Autofocus performance defines the capacity to reliably capture sharp images, especially for dynamic subjects such as wildlife, sports, or candid street moments.

• Canon’s A3400 IS: Utilizes a 9-point contrast detection AF system complemented by face detection and continuous AF modes. Touch-to-focus on the LCD enhances compositional control. The hybrid assisted AF modes help in stationary and slow-moving subjects but the single-shot speed and tracking lag are evident in fast-action scenarios.

• Panasonic’s S1: Employs an 11-point contrast detection AF but lacks continuous or face detection AF modes. Live view AF is available but limited to single-shot focus only, which means it struggles with tracking motion, making it less suitable for moving subjects.

Neither camera supports phase detection AF or advanced eye/animal tracking focusing found in modern cameras, limiting their effectiveness in sports or wildlife photography where accurate, rapid tracking is essential.

Burst Shooting and Shutter Performance

Continuous shooting capabilities reflect a camera’s burst mode performance, crucial for capturing action sequences.

The Canon A3400 IS supports 1 frame per second (fps) continuous shooting - modest by today's standards but typical for affordable compacts. Panasonic’s specifications omit continuous shooting support, indicating a lack of continuous burst option or extremely slow frame rates.

Shutter speed ranges also influence shooting versatility:

• Canon’s shutter speed ranges from 15 seconds to 1/2000 sec, allowing for long exposures in night photography and adequate fast-speed capture.

• Panasonic’s shutter speed ranges from 8 seconds to a maximum of 1/1600 sec, slightly shorter for fast shutter speeds, potentially less ideal for action freezing.

Flash and Low Light Capabilities

Both cameras include built-in flashes with similar maximum flash ranges: Canon’s effective up to 3.00 meters and Panasonic slightly better at 3.30 meters.

Flash modes on the Canon have a broader offering (Auto, On, Off, Red-Eye, Slow Sync) compared to Panasonic’s more limited options (Auto, On, Off, Red-Eye reduction). Slow Sync flash on Canon supports balanced ambient and flash exposure, a beneficial option for night portraiture.

Neither camera features hot-shoe mounts for external flashes, limiting expanded lighting setups.

The Canon’s optical image stabilization helps mitigate blur in low light, as does Panasonic’s optical stabilization. However, both cameras’ small sensors and modest maximum ISOs limit low-light performance relative to larger-sensor models.

Video Functionality: Basic but Functional

For casual videographers, the video specs provide a baseline understanding of capabilities.

• Canon A3400 IS: Supports 720p HD video at 25 fps in H.264 format. It also offers 640x480 resolution at 30 fps. No external microphone input or headphone monitoring exists, limiting audio controls.

• Panasonic DMC-S1: Records 720p at 30 fps in Motion JPEG format, which is larger in file size and lower in compression efficiency than H.264. Similar to Canon, it lacks audio connectivity ports.

Neither model supports 4K or high frame rate video modes, reflecting their entry-level, early 2010s design focus. Video autofocus during recording is limited, and stabilization helps partially compensate for hand movements.

Battery Life and Storage

Battery endurance defines usability during event shoots or travel.

• Canon A3400 IS utilizes an NB-11L battery pack delivering approximately 180 shots per charge, relatively low and necessitating spares for longer outings.

• Panasonic S1 offers marginally better battery life at 240 shots, improving usability for day trips.

Both accept SD/SDHC/SDXC memory cards, with Panasonic also supporting internal storage - though limited in capacity.
