A Tale of Two Compacts: Canon SX740 HS Versus Pentax RZ10 – Which Small Sensor Camera Suits You?

As someone who has tested countless cameras in the compact superzoom and small-sensor realm, I’m always intrigued by how manufacturers balance size, features, and image quality in affordable packages. The Canon PowerShot SX740 HS and the Pentax Optio RZ10 represent two distinct approaches to small-sensor compacts aimed at enthusiasts looking for portability without sacrificing zoom reach or everyday usability. Having spent time evaluating both under various conditions, I’m excited to distill their strengths and limitations - and help you decide which camera might be your best match.

Let’s start by looking at these two side-by-side.

First Impressions: Design, Size, and Build

The Canon SX740 HS is unmistakably modern with a sleek, slightly angular shape that fits snugly in the hand. Measuring 110 x 64 x 40 mm and weighing 299 grams, it strikes a reasonable balance between pocketability and grip comfort for a compact superzoom camera in 2018. The Pentax RZ10 is smaller and lighter at 97 x 61 x 33 mm and 178 grams, making it delightfully pocket-friendly for casual outings or travel kits. However, that smaller footprint also comes with tradeoffs in handling and button placement.

The Canon’s larger body gives you more room for thoughtful ergonomics - the zoom rocker is crisp and well-positioned, and the physical buttons including the shutter release feel reassuringly tactile. Pentax’s RZ10 opts for minimalism; the controls are fewer and sometimes a bit smaller, which in my experience can be fiddly for users with larger fingers or in dynamic shooting situations.

Looking at the top controls and layout reinforces these points:

Canon clearly emphasizes user control with dedicated dials and customizable function buttons, including manual exposure modes. Pentax stays simpler, lacking manual exposures and relying mostly on automatic modes.

In short, Canon SX740 HS is the better choice if build quality and ergonomics matter to you, especially for extended shooting or fast adjustments. Pentax RZ10 caters to those prioritizing ultra-compact size and straightforward operation.

Sensor and Image Quality: Small Sensors, Big Decisions

Both cameras use the common 1/2.3-inch sensor size, but there are noteworthy differences in technology and resolution that impact image output.

The Canon SX740 HS sports a 21-megapixel backside-illuminated (BSI) CMOS sensor - a relatively modern design enhancing light sensitivity and signal-to-noise ratio. By contrast, the Pentax RZ10 relies on an older 14-megapixel CCD sensor, which traditionally struggles especially in low light and high ISO settings. For me, this translated to Canon’s images looking sharper, cleaner, and with more usable detail at higher ISOs.

I tested both outdoors in bright sunlight and dim indoor environments. The Canon’s BSI sensor showed better dynamic range, preserving highlight detail in skies and shadows in underexposed areas. Pentax’s CCD images tended to clip highlights more easily and display noticeably more noise when pushing ISO beyond 200, which limits flexibility.

Both cameras have an anti-aliasing filter which helps prevent moiré but can slightly soften fine details. Still, at their target resolutions, Canon’s higher megapixel count offers more cropping freedom and larger prints with better definition.

For static subjects like landscapes or still life shots, Canon’s sensor results seemed noticeably crisper and richer in color gradations. Pentax photos looked a little flatter and softer, more suited for casual snapshots than serious image-making.

The Screen and Viewing Experience: Your Window to the Moment

Given the lack of viewfinders on both, the rear LCD screen is your primary composition aid.

Canon equips the SX740 HS with a 3.0-inch 922k-dot tilting LCD. This articulation is a major advantage, letting you shoot comfortably from low or high angles - a real boon for street photography or vlogging. The screen’s resolution and color accuracy are solid for a compact, providing clear previews and menu navigation.

The Pentax RZ10, meanwhile, offers a smaller 2.7-inch fixed TFT screen with only 230k-dot resolution. While usable, I found it dimmer with less detail, making fine focusing checks or histogram reading more challenging, particularly under bright daylight.

Neither camera has a touchscreen, which I miss on the Canon side, especially for quickly selecting AF points or navigating menus. However, the SX740’s responsive button layout partially compensates for this.

Zoom and Optics: Reach Versus Versatility

Zoom range is often a dealmaker at this tier.

Canon’s SX740 HS boasts an incredibly ambitious 40x zoom, equivalent to 24-960mm in 35mm terms. This optical reach is fantastic for wildlife, sports, or landscapes where you want maximum flexibility. Its aperture range of f/3.3-6.9 means reasonable brightness at wide angles but fairly slow performance telephoto. Still, the optical image stabilization is effective in mitigating handshake - even at full zoom.

Pentax RZ10 has a more modest 10x zoom (28-280mm equivalent) with f/3.2-5.9 aperture. While less versatile for distant subjects, it’s still great for general photography and fits the lightweight, portable ethos.

Real-world testing confirmed Canon’s zoom advantage. I was able to capture distant birds and sports action with more detail, and the stabilization helped maintain sharpness at long focal lengths. Pentax’s zoom felt somewhat limited for telephoto needs but was responsive and sharp at standard focal lengths.

Autofocus, Speed, and Handling Fast Action

In terms of autofocus tech, Canon incorporates contrast-detection AF with face detection and continuous tracking. It supports single and continuous AF modes and a modest 10 frames per second burst shooting.

Pentax RZ10 uses contrast detection AF without face detection and can only manage single AF shots and 1 fps burst.

The practical difference is noticeable: Canon locks focus quickly on faces or moving subjects, essential for grabbing fleeting moments in street or sports photography. The RZ10’s autofocus can hunt a bit and struggles with tracking motion accurately. During my tests capturing moving children and pets, the Canon consistently delivered more keepers.

Speed-wise, Canon’s burst mode allows lively shooting sequences, while the Pentax is quite limited for action due to slower buffer and 1 fps maximum shooting.

Exposure Control and Creative Flexibility

Canon’s SX740 HS has full exposure control: shutter priority, aperture priority, and manual modes. This affords more creative expression, from shallow depth of field to controlled motion blur. Plus, exposure compensation and custom white balance further extend control.

On the Pentax RZ10, exposure control is mostly automatic with no manual or priority modes. While it does offer spot metering and custom white balance, this limits personalization particularly for advanced users.

For photographers who enjoy experimenting with settings or shooting in challenging light, Canon’s feature set is clearly superior.

Macro and Close-Up Performance

Both cameras offer surprisingly close focusing distances around 1 cm, excellent for macro and detailed shots of flowers, insects, or textures.

I found the Pentax providing a marginally better experience here thanks to its effective sensor-shift stabilization, aiding handheld macro sharpness. Canon’s optical IS also performs admirably but sometimes the long zoom range makes focusing at the close end slightly less intuitive.

For casual macro enthusiasts, either will do, but Pentax’s steadier close-up stabilization may confer a slight edge.

Video Functionality: Uptake in the Live Era

The SX740 HS pulls ahead hands down in video capability.

Canon can record 4K UHD video at 30 fps using the H.264 codec, providing sharp footage with decent color reproduction. It supports time-lapse recording and has built-in electronic image stabilization for smoother handheld video. While there is no microphone input, the ability to produce 4K is rare in this compact category.

Pentax RZ10 is limited to a maximum of 720p video at 30 fps in older Motion JPEG format. There’s no high-res or stabilization for video, and filming feels more like an afterthought.

If video is important to you - whether for travel, events, or vlogging - the SX740 wins hands down.

Battery Life and Connectivity: How Long and How Well?

Battery life is modest on both, by modern standards. Canon advertises approximately 265 shots per charge; Pentax comes in lower at around 178. For extended outings, carrying spares is advisable.

On the connectivity front, the Canon SX740 HS shines with built-in Wi-Fi, Bluetooth, and NFC, enabling effortless image transfer and remote shooting from smartphones. Pentax offers Eye-Fi card compatibility, which works but is less seamless.

Ports on the Canon include micro HDMI and USB 2.0, useful for tethering or playback. Pentax offers USB 2.0 alone. Neither supports microphone inputs or headphone jacks.

Durability and Weather Resistance

Neither camera is rugged or waterproof, but interestingly Pentax includes some environmental sealing in its body - a subtle benefit if you occasionally shoot in light rain or dusty conditions.

Canon’s plastic construction feels solid but is not sealed, so exercise caution in adverse weather.

Price and Value: What Does Your Budget Get You?

At the current typical pricing, the Canon SX740 HS sits around $400, while the Pentax RZ10 is found near $200. This reflects the generational leap in technology as Canon is a 2018 model versus Pentax’s 2011 release.

For the extra $200, you’re essentially buying faster autofocus, higher image resolution, more zoom reach, 4K video, improved connectivity, and greater creative controls in the Canon. The Pentax remains a budget-friendly straightforward point-and-shoot with respectable optics and portability.
