Canon SX40 HS vs Pentax X90: An In-Depth Faceoff of Small Sensor Superzoom Bridge Cameras

When shopping for a superzoom bridge camera, the Canon PowerShot SX40 HS and the Pentax X90 often pop up as contenders from the early 2010s era, both designed for enthusiasts craving expansive zoom ranges without hassle of interchangeable lenses. Although similar at a glance, these two cameras offer distinct experiences in handling, image quality, and feature sets built around their small 1/2.3” type sensors.

Having tested both extensively in studio, field, and high-action scenarios over the years, I aim to help you decipher which merits your investment according to your photographic goals and style. This hands-on comparison takes you through sensor performance, ergonomics, autofocus, video capabilities, and more - grounded in personal experience paired with technical analysis.

First Impressions: Handling and Ergonomics

Physical design and control layout directly impact how a camera feels during prolonged shooting sessions. Both the Canon SX40 HS and the Pentax X90 embrace the classic bridge camera look with SLR-style grips and extensive zoom ranges, yet subtle differences stand out.

Canon SX40 HS:
Tipping the scales at 600 grams and measuring 123x92x108mm, the SX40 HS offers a robust feel with a comfortably deep grip that allows secure handling even with large lenses attached. The inclusion of a fully articulated 2.7-inch screen was a pleasant surprise at the time, providing flexibility for shooting at odd angles - a feature still highly relevant for vlogging or macro work.

Pentax X90:
Weighing less at 428 grams and slightly more compact at 111x85x110mm, the X90 favors portability without sacrificing the bridge camera silhouette. Its fixed 2.7-inch screen, though not articulated, has decent brightness and clarity for composing shots, but limited frame flexibility made me miss the Canon’s range especially in tight or low-angle street photography.

While both cameras lack weather sealing - a critical consideration if you shoot in challenging environments - the Canon’s heft contributes to a feeling of sturdiness, which over lengthy handheld wildlife shoots reduces fatigue.

Button Layout and User Interface: Keeping Controls Close at Hand

Ease of access to key settings like ISO, exposure compensation, and autofocus modes can make or break quick adaptability. Testing both cameras outdoors, I noticed distinct user interface philosophies.

The Canon SX40 HS features a well-spaced top dial and rear control cluster. All fundamental modes - manual, aperture priority, shutter priority - are easily accessible without menu diving. Its dedicated exposure compensation dial is a boon during changing light conditions, offering tactile feedback. Personally, I found the non-touch, but articulated LCD coupled with clearly labeled buttons ideal for fast adjustments during action sports or macro sessions.

Conversely, the Pentax X90 deploys a slightly cluttered top plate with fewer customizable shortcut buttons. The lack of an articulated screen and illuminated buttons somewhat hindered rapid changes under dim conditions. However, its “Prime” processor contributes to a snappier menu navigation experience, beneficial when needing to tweak settings on the fly.

Both cameras scored well in my hands-on autofocus selection trials, although I preferred the Canon’s AF point selection simplicity.

Sensor Specifications and Image Quality: What the Numbers Say vs What I Saw

Both cameras house a small 1/2.3" sensor with approximately 12-megapixel resolution. This shared sensor size dictates a certain baseline image quality, but the technologies underpinning them create notable differences.

• Canon SX40 HS uses a BSI-CMOS sensor, generally favorable for improved light gathering and noise control.
• Pentax X90 relies on a CCD sensor, known for strong color fidelity and chromatic accuracy but traditionally lagging behind CMOS in noise performance, especially at higher ISOs.

During controlled lab tests, the Canon consistently delivered slightly better high ISO images with reduced luminance noise from ISO 800 upwards and retained more highlight detail in RAW-like JPEG output. The Pentax’s base ISO starting at 80 provided crisp daylight images, but noise became very evident beyond ISO 400, limiting low-light utility.

In real-world landscape shoots with mixed lighting, I favored the Canon’s dynamic range - shadows lifted more gracefully without crush, and subtle gradations remained intact. Meanwhile, Pentax photos had a distinctive color palette richer in warm tones, which may appeal to portrait shooters aiming for natural skin rendering under golden hour light.

Neither camera supports RAW format, a caveat for pros requiring post-processing flexibility. For casual shooters, the high-quality JPEGs produced by both cameras are perfectly serviceable.

Autofocus Performance and Accuracy: Tracking the Action

A core strength for bridge cameras is their ability to snap fast-moving subjects with accuracy, especially through extended zoom ranges.

The Canon SX40 HS shines here with its Hybrid Contrast Detection autofocus system, face detection capability, and nine focus points. In my wildlife tests - tracking birds in flight or squirrels against complex foliage - the continuous AF struggled occasionally but remained more reliable than the Pentax, especially with moving subjects at longer focal lengths.

The Pentax X90 has nine autofocus points as well but lacks face and animal eye detection. Its contrast-detection-only AF system was slower to lock focus and less consistent with tracking in dynamic scenarios, which I found frustrating during my sports and street photography walks.

In continuous shooting, the Canon edges ahead with 10 fps - ideal for burst shooting sports and wildlife - while Pentax doesn’t specify continuous rates and performed more sluggishly in practice.

Video Capabilities: Under the Hood and On the Move

Video functionality is a deciding factor for many buyers, especially hybrids who want stills and moving images without multiple devices.

Both cameras offer HD video but with differing specs:

• Canon SX40 HS records Full HD 1080p at 24 fps with H.264 encoding and includes image stabilization. The optical zoom maintains smooth focus transitions, which I appreciated capturing hiking scenes. However, there’s no external mic input, limiting audio quality options beyond the built-in mono mic.

• Pentax X90 maxes out at 720p 30 fps and uses Motion JPEG - a format resulting in larger files and less compression efficiency. No stabilization acts during video, making handheld clips prone to shakiness. The absence of a microphone port further constrains sound quality.

If video is a priority - think travel logs or event coverage - the higher resolution and stabilization on the Canon serve as strong advantages.

Lens and Zoom Performance: Reach and Image Rendering

Superzoom cameras’ defining feature is their lens range adaptability. The Canon SX40 HS sports an ambitious 24-840mm equivalent zoom, while the Pentax X90 offers 26-676mm.

Though close in range, the Canon’s slightly wider wide-angle start and longer telephoto reach enhance versatility. The Canon also offers a variable maximum aperture of f/2.7-5.8, slightly brighter at the long end than the Pentax’s f/2.8-5.0.

In the field, the Canon’s optics demonstrated better sharpness and less chromatic aberration beyond 400mm zoom compared to the Pentax, which showed more softness and fringing. Personally, I observed the Pentax excelled in close focusing with a macro range down to 1 cm versus Canon’s nominal 0 cm - translating to more detailed close-ups of flowers and insects.

Image stabilization differences also matter: Canon’s optical stabilization system proved slightly more effective for telephoto use, reducing blur caused by hand movement.

Build Quality and Durability: Ready for Fieldwork?

Neither camera boasts professional-grade weather sealing, impact resistance, or freezeproofing - common for bridge cameras in this segment.

Pentax has a slight edge with a solid chassis weighing less but feeling sturdy. Canon feels more substantial, balancing heft and grip comfort.

For extended travel or outdoor use, adding protective gear or cases is advised regardless of choice.

LCD and Viewfinder Experience: Composition Tools

The Canon’s 2.7-inch fully articulated LCD screen allows shooting from awkward angles and makes video autopilot easier. The Pentax’s fixed screen is adequate but less flexible.

Both cameras deploy electronic viewfinders, essential for bright sunlight framing. They do not specify resolution, but the Canon’s EVF gave a clearer, more responsive live view in diverse lighting, as I tested in urban street shooting.

Battery Life and Storage: Practical Shooting Duration and Capacity

The Canon SX40 HS uses an NB-10L battery pack rated for approximately 380 shots per charge - a respectable figure for its class. I managed a full day shooting landscapes and birds without a recharge.

Pentax’s battery life is unspecified by the manufacturer but my testing showed it to be slightly lower, likely owing to less power-efficient components. It uses a D-L106 battery.

Both cameras support SD/SDHC/SDXC cards, with the Pentax allowing internal memory as backup. Single card slots mean managing storage space carefully.

Connectivity and Wireless Features

Both cameras support Eye-Fi card compatibility, enabling Wi-Fi transfer of images through specialized cards - not built-in Wi-Fi. No Bluetooth or NFC is present.

HDMI ports on both facilitate easy playback on TVs or monitors.

Real-World Performance: Samples and Scoring Overview

I conducted extensive side-by-side shooting in diverse scenarios: portraits, landscapes, wildlife, macro, and street photography.
