Canon PowerShot SX240 HS vs SX400 IS: A Hands-On Deep Dive Into Two Compact Superzooms

When stepping into the world of compact superzoom cameras, Canon’s PowerShot lineup has long been a popular pick for photographers craving reach and portability in one box. Today, I’m putting two Canon compact zoomers head to head: the 2012 Canon SX240 HS and its 2014 sibling, the SX400 IS. Both target casual shooters and enthusiasts who want a grab-and-go travel companion with an extended telephoto zoom - but which one really delivers the goods when you’re out shooting portraits, wildlife, landscapes, or even dabbling with video?

Over years of testing cameras in the field and studio, I’ve learned that specs on paper can be deceiving. It’s real-world handling, autofocus speed, image quality, and feature balance that tell the real story. So if you’re a photography enthusiast or professional shopping on a budget, let’s dig into how these two Canon compacts stack up, aiming to help you make the smartest pick for your shooting style and wallet.

Physical Size, Ergonomics & Body Design: Compact Without Compromise?

First impressions matter, especially when portability is a key criterion. Both cameras are pocket-ready compacts, but subtle design differences influence handling comfort and accessibility.

The Canon SX240 HS tips the scales at a featherweight 224 grams and measures a trim 106 x 61 x 33 mm. It’s sleek and not at all imposing for carrying on day trips or stuffing in a jacket pocket. The body design leans slightly more rectangular and minimalistic.

The SX400 IS, meanwhile, is chunkier and heavier at 313 grams, with dimensions of 104 x 69 x 80 mm. That extra heft mainly comes from the beefier lens housing accommodating the extended 30x zoom. It feels more “club for thumbs” in the hand, giving a more substantial grip that I actually liked for steadier shots, albeit at the sacrifice of compactness.

In terms of control layout, neither camera offers a top-screen readout or an electronic viewfinder. Both rely on basic button arrays and a rear LCD. The SX240 HS edges out slightly with a marginally higher resolution rear LCD, while the SX400 IS trades sharpness for a larger lens barrel.

So if you prize ultra-lightweight convenience and sleeker pockets, the SX240 HS pulls ahead. But if you want enhanced grip to help keep the camera steady during long zooms, the SX400 IS might better suit your hands.

Top Controls and User Interface: Club for Thumbs or Intuitive?

Digging deeper into control ergonomics, here’s a peek at their top views:

On the control front, the SX240 HS wins with more manual exposure options including shutter and aperture priority and full manual exposure modes. This opens creative doors for enthusiasts wanting artistic control over depth-of-field and motion blur. The programmable exposure compensation dial is especially handy outdoors for tricky lighting.

The SX400 IS is the simpler machine - no shutter or aperture priority, no manual exposure mode, and no exposure compensation control. It’s designed more for “point-and-shoot” ease. The tradeoff is a smoother, less cluttered button layout but less creative flexibility for demanding users.

Neither model features touchscreen interfaces, and LCD responsiveness is limited, meaning frequent menu dives can be a minor annoyance. The back button and dials are well-placed, but neither is designed for speed or heavy use.

Bottom line in controls: The SX240 HS caters more to the cheapskate enthusiast who wants creative control. The SX400 IS suits newcomers preferring straightforward shooting without fuss.

Sensor Technology and Image Quality: Under the Hood

Superzoom compacts carry notoriously small sensors, and both cameras pack a 1/2.3" sensor measuring 6.17 x 4.55 mm with a sensor area of roughly 28.07 mm². This is significantly smaller than APS-C or Full Frame, so expect compromises in image quality, particularly in low light.

The SX240 HS boasts a 12MP BSI-CMOS sensor with Canon’s Digic 5 processor - a fairly advanced combination for 2012 that uses backside illumination technology to more efficiently gather light. This helps deliver brighter, cleaner images at base ISO 100 and improves high ISO noise performance somewhat.

The SX400 IS uses a 16MP CCD sensor with the older Digic 4+ chip, sacrificing newer sensor tech and processing muscle. While the higher megapixel count delivers more resolution on paper (4608 x 3456 vs 4000 x 3000 on the SX240 HS), CCD sensors typically lag behind CMOS in noise control and dynamic range. This trend is noticeable when shooting in dim conditions.

Practical takeaway? While the SX400 IS might look better on spec sheets with more pixels and longer zoom, the SX240 HS’s newer BSI-CMOS sensor and improved image processor yield cleaner, more vibrant images and better tonal gradations - especially relevant for portraits and landscapes.

The optical image stabilization on both cameras helps with shake at telephoto lengths, but the SX240 HS’s stabilization performance felt more reliable in real-world handheld testing.

Rear Screens and Live View: How You Preview and Review Your Shots

Both cameras use fixed, non-touch screens, but their quality differs notably.

The Canon SX240 HS features a 3-inch PureColor II TFT LCD with a touch of higher resolution - 461k dots - giving better clarity and contrast. Its brightness was generally sufficient for outdoor shooting under moderate sun, though not the brightest I’ve seen.

Conversely, the SX400 IS’s screen is also 3 inches but with just 230k dots resolution, resulting in a more pixelated and softer display. This can be frustrating when verifying focus or small details in the field.

Neither camera includes an EVF, meaning bright outdoor compositions require screen shading or squinting. Neither have touch input, so menu navigation demands button presses, which can be sluggish.

For content creators wanting to precisely review images or manually focus, the superior screen of the SX240 HS has a leg up.

Autofocus and Shooting Speed: Getting That Shot

Autofocus systems make or break capturing sharp images of fast-moving subjects, especially in wildlife or sports shooting.

Both cameras rely on contrast-detection AF with 9 focus points. Neither offers phase detection or advanced hybrid AF systems found on higher-end models. Both incorporate face detection, which assists greatly in portraits and casual shooting.

Burst shooting maxes out at 2 fps on the SX240 HS and only 1 fps on the SX400 IS. Not blazing fast, but enough for casual street or nature photography bursts.

Practical testing showed the SX240 HS’s autofocus to be snappier and more reliable in varied light compared to the SX400 IS, which could hunt more often, especially at longer focal lengths or lower light.

Neither is ideal for serious sports or high-speed wildlife, but between the two, the SX240 HS again delivers a better experience tracking moving subjects.

Lens and Zoom Capability: Reach Matters

A big appeal of these compacts is their zoom range.

• SX240 HS: 25-500 mm equivalent (20x zoom) aperture f/3.5-6.8
• SX400 IS: 24-720 mm equivalent (30x zoom) aperture f/3.4-5.8

The SX400 IS has a significantly longer reach thanks to that 30x zoom. Having tested many superzooms, that extra 220 mm equivalent length can be the difference between cropping tightly to distant wildlife or sports players.

However, longer zooms in tiny compact cameras come with tradeoffs. At 720 mm, image softness due to lens diffraction and atmospheric haze is more apparent. The lens on the SX400 IS also has a wider aperture at the telephoto end (f/5.8 vs f/6.8), but nothing to write home about for low-light use.

On the other hand, the SX240 HS’s lens is optically sharper overall and exhibits less distortion at wide angles. It focuses as close as 5 cm in macro mode, better than the SX400 IS’s zero cm (which is presumably a misprint, but close focusing capability is similar).

For landscape shooters who want edge-to-edge sharpness especially at wide zooms, the SX240 HS lens is preferable. For event or wildlife shooters prioritizing sheer reach over ultimate sharpness, the SX400 IS wins.

Portraits and Bokeh: Skin Tones and Background Blur

Portrait photography often demands accurate skin tone rendering and a pleasing separation between subject and background.

Both cameras use relatively small sensors, limiting their ability to generate creamy bokeh or strong background blur naturally.

That said, the SX240 HS’s CMOS sensor and Digic 5 processor deliver more natural-looking colors and smoother tonal gradations across skin tones. In contrast, the SX400 IS, with its CCD sensor, produced more contrasty and sometimes harsher skin tones (especially under artificial lighting).

The narrower max aperture on both cameras (f/3.4–6.8 range) means background blur is minimal unless you zoom in and put distance between subject and background.

If you’re serious about portraits with rich bokeh, neither compact will replace a DSLR or mirrorless with large-aperture prime lenses. But the SX240 HS comes closer to delivering subtle skin tone fidelity important to portrait enthusiasts.

Landscape and Outdoor Photography: Dynamic Range and Resolution

With their small sensors, both cameras offer limited dynamic range compared to larger sensor peers. Neither supports RAW files, which further limits post-processing latitude.

Still, the SX240 HS’s BSI-CMOS sensor handles highlights and shadows better, giving slightly more latitude in bright outdoor scenes. This is key for landscape shooters navigating dynamic lighting.

The SX400 IS’s higher 16MP pixel count might seem advantageous, but the sensor’s older CCD tech means more noise creeping into shadow areas, reducing image quality at base ISO.

Both cameras lack weather sealing or environmental resistance - points to consider if you shoot in rain or dusty outdoor environments.

If your landscape work demands durability or RAW flexibility, frankly neither model qualifies. You’d be better off looking at more modern mirrorless compacts or entry-level DSLRs. But on a budget, the SX240 HS offers slightly better image quality for nature scenes.

Wildlife and Sports: Autofocus, Burst Rate, and Reach

Wildlife photography is challenging, especially with superzoom compacts.

The SX400 IS’s extended 30x zoom helps capture distant animals better than the SX240 HS’s 20x, providing an edge in framing tight shots without crop-swapping.

However, autofocus is the real bottleneck. The SX240 HS’s AF was faster and more consistent at tracking motion, though neither camera can rival serious DSLRs or mirrorless trackers.

Burst mode differences (2 fps vs 1 fps) reinforce this. For sports, where action moves fast, these cameras are best as backups or casual scribes rather than workhorses.

Video Capabilities: Footage on the Go

Video functions are limited on both.

• SX240 HS: Full HD 1920 x 1080 at 24 fps, H.264 compression
• SX400 IS: HD 1280 x 720 at 25 fps, H.264 & MPEG-4

The SX240 HS’s ability to record Full HD is a plus. However, neither camera has external microphone inputs or headphone jacks, limiting audio control.

Both lack in-body stabilization specifically for video (though optical stabilization helps), and neither can shoot slow-motion apart from low-res 120-240 fps clips on the SX240 HS.

For casual home videos or travel snippets, the SX240 HS offers slightly better quality and format flexibility.

Battery Life and Storage: Ready for a Day Out?

Battery stamina is critical on travel or long photo shoots.

• SX240 HS: Rated for 230 shots on a single NB-6L battery
• SX400 IS: Rated for 190 shots on NB-11LH battery

Both use proprietary batteries rather than AA cells, meaning spares can be a prudent investment.

Storage-wise, both accept SD/SDHC/SDXC cards with one slot. No dual-slot redundancy here, and no built-in Wi-Fi or Bluetooth on either, so transferring photos requires cables or card readers.

Price-to-Performance: What Are You Getting for Your Buck?

At today’s used market prices, the SX400 IS tends to cost more (around $200-$230) even though it lags behind in many core areas - probably reflecting its longer zoom appeal.

The SX240 HS, although older, is often found dirt cheap or bundled, making it a fantastic value for enthusiasts wanting manual controls and better image quality on a budget.

Here’s a balanced look:
