Compact Showdown: Canon PowerShot ELPH 170 IS vs. Panasonic Lumix DMC-FS42

In the world of ultracompact cameras, choices abound yet meaningful distinctions can be subtle. Recently, I had the opportunity to put two popular models head-to-head: the Canon PowerShot ELPH 170 IS (also known as the IXUS 170) and the Panasonic Lumix DMC-FS42. Both were designed as point-and-shoot companions aimed at casual shooters demanding good image quality with pocketable convenience - but how well do they deliver beyond specs on paper?

Having tested thousands of cameras over 15 years, I'll walk you through a comprehensive, hands-on comparison from multiple photographic perspectives. We’ll dive deep into technical attributes, real-world shooting performance, and user experience to help you settle on the best fit for your photographic style and budget.

Getting a Grip: Size and Handling Differences

When I first held these models side-by-side, the physical nuances stood out despite their similar ultracompact category. The Canon 170 IS measures approximately 100x58x23 mm and weighs 141g, while the Panasonic FS42 is slightly smaller at 98x55x22 mm and lighter at 132g.

Canon’s PowerShot felt a tad chunkier in my hand, which, paradoxically, enhanced grip confidence - especially useful during extended handheld shooting, as I found the Panasonic a little too dainty, making it prone to slight handling wobbles if you’re not careful. The Canon’s buttons were positioned for intuitive reach and tactile feedback. Conversely, the Panasonic’s controls appeared more compact, which might appeal to users prioritizing pocket space over ergonomic comfort.

Layout and Controls: Quick Access or Compromise?

Examining their control surfaces further, I observed subtle design philosophies at play.

Canon's layout is minimalist yet thoughtfully spaced, balancing playback, shooting modes, and zoom toggles. The lack of manual focus options and exposure bracketing is an expected concession in this class, but I appreciated the Canon’s dedicated self-timer and flash mode buttons. The Panasonic FS42 also features a streamlined top plate, but with fewer accessible external buttons, nudging users heavily towards on-screen menus.

Neither camera offers a touchscreen, and both dispense with viewfinders - relying exclusively on LCD framing.

Sensor Specs and Image Quality Insights

Sensor technology is foundational to image quality, and here lies a sharp contrast.

Both cameras utilize 1/2.3” CCD sensors, though Canon’s sensor area (28.07mm²) is marginally larger than Panasonic’s (24.74mm²). Canon packs 20 megapixels versus Panasonic’s 10 megapixels, effectively doubling the resolution potential. However, higher pixel counts on small sensors risk increased noise and reduced dynamic range.

From my testing, the Canon’s DIGIC 4+ processor did a commendable job managing noise at base ISO 100-200, producing crisper images with finer detail preservation. Panasonic’s older-generation chip showed slightly softer rendering with increased chroma noise at ISO 400+. The canonical aperture range on Canon’s 25–300mm (12x optical zoom) lens is slower (f/3.6-7.0) compared to Panasonic’s brighter 33–132mm (4x zoom) lens at f/2.8-5.9, benefitting the Lumix in low-light or bokeh-sensitive situations.

Neither supports RAW files or extended ISO options, which limits flexibility for post-processing - a key limitation for more advanced users.

Viewing and Interface: The Windows to Your Creativity

The LCD screen serves as the primary window for framing and reviewing images.

The Canon ELPH 170 IS boasts a 2.7-inch fixed LCD with 230k-dot resolution, slightly larger than Panasonic’s 2.5-inch 230k-dot screen. Although both are non-touch, the Canon display has marginally better contrast and color accuracy in sunlight, crucial for outdoor shooting. However, the lack of articulating screens or electronic viewfinders on either camera restricted shooting angles and reduced versatility in bright environments.

Menu navigation on both feels dated by modern standards - Panasonic’s interface is more basic, with fewer customization options, whereas Canon’s menus offer limited white balance selection and exposure compensation options, though no full manual modes.

Paint with Light: Autofocus and Exposure Performance

Fast and precise autofocus can vastly affect your ability to capture fleeting moments.

The Canon employs a contrast-detection AF system with 9 selectable autofocus points and face detection, whereas Panasonic relies on contrast autofocus but lacks face detection or any selectable points.

In my wildlife and action shooting trials, Canon’s AF was noticeably more responsive and accurate, particularly in decent light conditions. Face detection helped in portrait scenarios significantly, ensuring sharper eye focus when snapping quick family portraits. Panasonic’s autofocus lagged, especially under low-light or fast-moving subjects, occasionally hunting for focus.

Both cameras record images with fixed aperture priority - no aperture or shutter priority modes exist, constraining creative control.

Zoom and Lens Versatility: Reach Matters

The lens focal lengths reveal important user experience differences.

The Canon’s long 12x optical zoom (25-300mm equivalent) eclipses Panasonic’s 4x zoom (33-132mm) considerably, making it more versatile for everything from portraits to distant subjects, such as urban street scenes or casual wildlife outings. However, Canon’s narrower apertures at telephoto end make handheld shooting challenging in dim settings.

On the other hand, Panasonic’s brighter aperture starting at f/2.8 on the wide end delivers better low-light performance and more natural bokeh at shorter focal lengths, ideal for artistry in closeups and backgrounds.

Shooting Styles Explored: A Discipline-by-Discipline Breakdown

Let’s now analyze how both cameras perform across vital photographic genres I’ve tested extensively.

Portrait Photography

Capturing natural skin tones and expressive eyes demands accurate color rendition and reliable autofocus.

The Canon excels in face detection autofocus, locking onto subjects’ eyes and faces quickly, aiding in consistently sharp portraits. The 20MP sensor resolution helps deliver detailed skin textures, though the smaller f/3.6 aperture limits shallow depth of field effects.

The Panasonic, while featuring a brighter f/2.8 aperture at the wide end, lacks face detection, making sharp portraits a bit more hit-or-miss. Color rendering felt less warm compared to Canon and the 10MP sensor yielded softer details.

Landscape Photography

Landscape work rewards dynamic range, resolution, and durability.

Both cameras lack pro-level weather sealing and resistances, ruling out extreme conditions. In resolution, Canon’s 20MP sensor clearly leads, unlocking more generous crops and large prints.

Canon’s images showed stronger color fidelity and sharper details when shooting wide landscapes in daylight. However, limited dynamic range meant blown highlights were common without bracketing. Panasonic had slightly better shadow retention, likely due to larger pixel size on the sensor but at lower overall image resolution.

Wildlife Photography

Here, fast autofocus, zoom reach, and burst speed rule.

Canon’s 12x zoom and continuous shooting at 0.8 fps theoretically equips it better for casual wildlife capture, but the low continuous frame rate limits sequences. The Panasonic's 4x zoom and 2 fps burst rate are faster but with shorter reach.

Autofocus speed was another plus for Canon in daylight, but both are challenged tracking erratic wildlife behavior. Neither is ideal for dedicated wildlife enthusiasts requiring rapid-fire precision.

Sports Photography

Sports demand high frame rates and accurate tracking.

With burst at 0.8 fps for Canon and 2 fps for Panasonic, neither can compete with dedicated sports cameras. Canon’s autofocus tracking features marginally improve subject retention but struggles with fast, erratic motion.

In low light, both cameras suffer due to slow lenses and limited ISO range, making them unsuitable for serious indoor or night sporting events.

Street Photography

Discretion and portability are essential.

Both cameras’ small sizes favor street shooters. Panasonic’s lighter weight makes it easiest to carry all day, though Canon’s more tactile controls enable quicker adjustments on the fly. The slower autofocus on Panasonic might frustrate some.

Low-light shooting on the street is a challenge for both: Canon’s longer zoom implies a slower aperture and slower exposure times if handheld, whereas Panasonic’s brighter aperture aids ambient light capture but at lower resolution.

Macro Photography

Close focusing abilities influence outcomes here.

Canon’s 1cm macro focusing beats Panasonic’s 5cm minimum, facilitating tight close-ups with better magnification and detail. Optical image stabilization in Canon helps steady handheld macro shots - a big bonus for those naturalists or product shooters.

Panasonic's lack of any image stabilization and longer minimum focus distance limits macro potential.

Night and Astro Photography

High ISO performance and exposure flexibility count.

Neither camera supports high ISOs beyond 1600 or 1000 native, and noise is a limiting factor. Canon’s image stabilization helps handheld night shots minimally.

Neither offers bulb mode or manual exposure necessary for astrophotography or extended night exposures.

Video Performance

Video recording remains basic on both cameras.

Canon shoots up to HD 720p at 25fps using efficient H.264 compression - decent for casual sharing but no 1080p or high frame rates. Panasonic offers VGA and lower resolution video with Motion JPEG format, limiting quality and file sizes.

Neither offers external microphone input or image stabilization in video mode - major drawbacks for serious videographers.

Travel Photography

Here, versatility, battery life, and size matter.

Both cameras fit comfortably in jacket pockets or small bags. Canon’s longer zoom range suits versatile travel shooting but reduced battery life of around 200 shots per charge is a caveat - you’ll want spare batteries.

Panasonic’s lighter weight and slightly better screen contrast favor all-day use, though less zoom flexibility means you may miss distant subjects or architectural details.

Professional Use and Workflow Considerations

Neither camera supports RAW, limiting post-processing potential. Build quality is moderate without weather sealing or ruggedness for professional reliability. USB 2.0 serves transfer duties, but no wireless or HDMI outputs constrains tethering or fast workflows.
