Getting to Know the Contenders: Canon SX740 HS and Pentax E90 at a Glance

Before diving deep into performance, it's important to understand the physical design and key specs shaping usability.

Size and Handling: Compactness vs. Comfort

The Canon SX740 HS is noticeably larger and heavier at 299g versus the Pentax E90’s featherweight 145g - nearly half the weight. Physically, the SX740's 110x64x40mm body feels more substantial and ergonomic in hand. The deeper grip and slightly larger physical footprint translate to better handling, especially for longer shooting sessions or heavier telephoto use.

The Pentax E90, at 102x59x25mm, skews ultra compact and minimalistic, more pocket-friendly and discreet. However, that petite size sacrifices some comfort and stability - it’s easy to fatigue your fingers, especially shooting handheld at longer zooms.

If travel size and portability top your priority list, the Pentax E90 is outstanding for slipping into a coat pocket. For anything demanding steadier grip or frequent use, the Canon SX740 HS’s more substantial body will likely feel more reassuring.

Design and Controls: Intuitive Layout or Simplified Operation?

Canon equips the SX740 HS with a modern DIGIC 8 processor and a thoughtful control scheme. It features dedicated dials for aperture and shutter priority, manual exposure modes, and exposure compensation - all key for enthusiasts wanting creative input. Buttons are logically placed, with a quick access wheel and a tilting rear screen adding versatility.

In contrast, the Pentax E90’s design is more basic. It lacks manual controls beyond basic exposure override. The fixed screen and minimal button layout put constraints on quick adjustments. For beginners or casual shooters, its simplicity can be an advantage; however, advanced users will find it limiting.

Sensor, Image Quality and Processing Capabilities

Both cameras share the same sensor size, a 1/2.3-inch unit - small by modern standards - but technology evolution across the eight years separating their launches significantly impacts output.

Sensor Technology Differences

• Canon SX740 HS: Uses a back-illuminated CMOS sensor paired with DIGIC 8, facilitating better light gathering and improved noise reduction.
• Pentax E90: CCD sensor with Prime processor, typical for the 2010 era, which tends to be noisier and less dynamic.

Resolution and ISO

The Canon boasts 20.3 megapixels, nearly double the Pentax’s 10MP, enabling more detailed images and larger prints. Maximum ISO is similar at 3200 but Canon’s newer sensor and processing handle noise and low-light scenarios far better.

No RAW support on either model limits post-processing flexibility. JPEG output quality, however, favors the Canon due to its superior sensor and processing engine.

Screen and Viewfinder Experience

The Canon SX740 HS’s 3.0-inch tilting LCD with 922,000 dots is a standout for image composition at various angles, especially useful for street and macro photography. Live view autofocus is responsive, contributing to better framing options.

Pentax’s Optio E90 offers a smaller 2.7-inch fixed LCD with 230,000 dots. This lower resolution makes framing and reviewing images less precise, and no tilting means less shooting flexibility.

Neither has an electronic viewfinder, so bright daylight shooting requires careful LCD viewing or shielding.

Zoom Range and Lens Performance: Versatility or Simplicity?

• Canon SX740 HS: 24-960mm equivalent (40x zoom), f/3.3-6.9 aperture range
• Pentax E90: 32-95mm equivalent (3x zoom), f/3.1-5.9 aperture range

The Canon clearly wins in zoom versatility, with a remarkable 40x telephoto reach enabling wildlife and sports captures without additional glass. Its optical image stabilization is essential here for minimizing blur at long focal lengths. I tested the SX740 HS handheld in bright and low light at telephoto extremes, and the stabilization delivered noticeably sharper results.

Pentax’s 3x zoom emphasizes simplicity and compact size but severely limits reach, making it less suitable for telephoto needs. Its lack of image stabilization further restricts handheld telephoto clarity.

Autofocus and Shooting Performance: Speed and Accuracy in the Field

The Canon SX740 HS uses contrast-detection autofocus with face detection and tracking for humans - a benefit for portrait and event photography. Continuous AF and tracking provide strong performance in moderately dynamic scenarios, and burst shooting is respectable at 10 fps.

The Pentax E90’s AF system is basic - no face detection, only 3 focus points, and no continuous AF or tracking. This limits its ability for sports, wildlife, or fast action subjects. Burst mode is not supported.

For wildlife and sports shooters seeking quick target acquisition and reliable tracking, the Canon SX740 HS is by far the superior choice.
