Canon PowerShot A2300 vs Casio Exilim EX-Z90: A Hands-On Comparison of Two Compact Cameras for Everyday Photography

As an experienced reviewer who has tested thousands of cameras across all genres - from portraiture to wildlife - I often get asked: “Is this budget compact still worth considering?” The Canon PowerShot A2300 and Casio Exilim EX-Z90, both small-sensor compacts from the early 2010s, remain popular in the used market for casual shooters and beginners looking for lightweight, affordable options. But which one truly delivers better image quality, usability, and value in real-world shooting?

In this in-depth comparison, I’ll share hands-on insights and detailed technical analysis to help you decide which camera might fit your needs today. Although neither camera is a powerhouse by modern standards, you’ll find distinctions in image output, built features, and shooting versatility that matter if you’re using these cameras for travel, street, or family snapshots.

First Impressions and Handling: Size, Build, and Ergonomics

Starting with the basics, both cameras are pocketable compacts designed for simplicity, but I found subtle differences in how they feel in hand and operate during shooting.

• Canon A2300: Slightly larger at 95 x 54 x 20 mm and weighing 125 g, the A2300 sports a rounded body with a modest grip area. The layout is straightforward but limited - no external control dials and mostly automatic modes. The plastic construction, typical for this class, is light but not fragile. It fits comfortably for small to medium hands.

• Casio EX-Z90: Smaller and slimmer at 90 x 52 x 19 mm, weighing 121 g, the EX-Z90 is very pocket-friendly and stylistically sleek. Its metal-like finish gives a marginally more premium feel. The body is compact but ergonomics feel a bit more cramped, especially for extended shooting sessions.

Ergonomically, neither model offers dedicated dials or advanced manual controls, but the Casio includes manual focus - atypical in this segment - which could appeal to users wanting some creative control. The Canon lacks manual focus but benefits from simplified AF modes aimed at point-and-shoot ease.

In use, I found the Canon’s buttons more distinctly spaced, making it easier to operate without looking, while Casio’s resembled more minimalist designs that occasionally require menu diving.

For beginners or casual shooters valuing grab-and-go simplicity, Canon’s slightly larger but more accessible design may edge ahead. The EX-Z90’s slimline favors portability over tactile handling.

Image Sensors and Quality: The Heart of the Camera

Both cameras share similar sensor technology and size: a 1/2.3-inch CCD sensor measuring 6.17 x 4.55 mm, but with nuanced differences:

• Canon A2300: Offers a 16-megapixel resolution (4608x3456 pixels), which is relatively high for this sensor size. The pixel density pushes the sensor’s performance limits, typically resulting in more noise at higher ISOs. Maximum native ISO is 1600.

• Casio EX-Z90: Comes with a 12-megapixel (4000x3000 pixels) CCD sensor, slightly lower than Canon’s but still ample for prints and sharing. Maximum ISO 1600 native, with a lower base ISO of 64 for better daylight shots.

During detailed image inspections and testing in various lighting, here’s what I experienced:

• Resolution and Detail: The Canon’s higher megapixel count offers more detail in optimal lighting, beneficial for landscapes or printing medium-sized photos. However, due to the small sensor size, sharpness gains are subtle, and digital noise emerges quickly beyond ISO 400.

• Color and Dynamic Range: Both cameras use CCD sensors, which tend to produce pleasant color saturation and contrast. The Canon delivered more vibrant skin tones, useful for portraits, whereas the Casio had a neutral color balance but slightly narrower dynamic range, leading to more clipping in highlights.

• Low Light and Noise: Neither camera excels here, but the Casio with its lower base ISO had marginally cleaner shots at ISO 100-200, though both struggled beyond ISO 800 with evident grain. Canon’s higher resolution magnifies noise, which you can notice especially when cropping.

Overall, for best image quality, the Canon PowerShot A2300 has a slight edge in resolution and color rendition, but the Casio offers marginally better noise control for lower ISO shots.

Display and User Interface: Reviewing and Framing Your Shots

Despite their similar 2.7-inch LCD screens at 230k dots, both fixed and non-touch, real-world usability varies.

• Canon A2300: The screen provides clear daylight viewing with decent color reproduction. Navigation through menus is simplistic, focusing on automatic scene modes. No touchscreen means button presses for all settings.

• Casio EX-Z90: Matches Canon in screen size and resolution, but the interface is a bit more cluttered due to extra modes and manual focus. The LCD colors aren’t as vibrant, making outdoor preview less effective.

Neither camera has an electronic viewfinder, which in my experience can make low-light framing challenging. The fixed LCD is your only framing tool, so usability under bright sunlight is limited on both.

If you rely heavily on LCD previews for composing and reviewing, Canon’s screen is marginally better in brightness and color fidelity.

Autofocus and Performance: Speed, Accuracy and Shooting Experience

AF technology is a cornerstone of real-world usability. Here’s how the two compare:

• Canon A2300: Features 9 autofocus points with contrast-detect AF and face detection technology. In my tests, it focused reliably in good lighting, especially on faces, which is a big plus for casual portraits. Continuous AF is available but framed only for simple subjects. Burst speed is limited to 1 frame per second - slow but expected.

• Casio EX-Z90: Uses contrast-detect AF but lacks face or eye detection. No continuous AF support. In practice, I found it slower to lock focus, especially in dimmer conditions, and it occasionally hunted when subjects moved. No burst mode was specified, reflecting its emphasis on still image casual shooting.

Neither autofocus system can be expected to track fast-moving subjects accurately, ruling them out for sports or wildlife photography, but the Canon’s AF system is overall more capable and consistent.

Lens Versatility: Focal Range and Aperture Comparison

Both have fixed zoom lenses attached, meaning you cannot swap optics.

• Canon A2300: 28-140 mm (35mm equivalent), 5x optical zoom, aperture range f/2.8-6.9. The wider 28 mm starting focal length gives better framing flexibility for landscapes and group shots. However, the slower aperture at the telephoto end limits low light reach and bokeh potential.

• Casio EX-Z90: Shorter focal length range of 35-105 mm (3x zoom), aperture f/3.1-5.9. Slightly darker lens but longer minimum macro focus distance (10 cm vs Canon’s 3 cm), reducing edge macro capability.

Neither lens offers image stabilization, which is noticeable at longer focal lengths where hand shake affects sharpness, especially at slower shutter speeds.

For general travel and everyday shooting, Canon’s longer zoom and wider angle coverage provides more compositional versatility.

Flash and Low-Light Capabilities

Both include built-in pop-up flashes with a range of 3 meters, offering several modes.

• Canon: Has Auto, On, Off, Red-eye reduction, and Slow Sync modes, which helps in balancing ambient and flash light for portraits.

• Casio: Includes Auto, On, Off, Red-eye reduction, and Soft modes - soft mode being useful for diffused flash, which can render more natural skin tones.

Neither camera has external flash support, limiting flexibility.

In low light, with no optical stabilization and sluggish response, expect some softness or blurred shots handheld. The Canon’s more comprehensive flash modes might edge out for casual portraiture in dim environments.

How Do They Perform Across Photography Styles?

Let’s break down the strengths and weaknesses across common genres based on my experience capturing samples in each.

Portrait Photography

• Canon A2300: Face detection AF and a faster wide aperture at 28mm help produce sharp images with pleasant skin tones. Bokeh is limited due to sensor size and slow tele aperture, but the camera handles eye detection fairly well for its class.

• Casio EX-Z90: Without face detection, focus acquisition on people is slower, and colors tend toward neutral but less flattering. Bokeh and subject-background separation are weak.

Landscape Photography

• Canon’s wider 28mm equivalent and higher resolution yield more detailed and expansive images. Better exposure retention in highlights helps preserve sky details.

• Casio’s 35mm minimum focal length and lower resolution restrict framing breadth and detail capture.

Wildlife and Sports Photography

Neither is ideal due to slow autofocus and low burst rates.

• Canon’s 1 fps burst and face detection can keep pace with slow-moving pets in daylight but won’t track birds or athletes.

• Casio’s lack of continuous or tracking AF means many missed shots.

Street Photography

• Canon’s modest size and faster lens at wide focal lengths make it more adaptable for candid shots.

• Casio’s smaller size is advantageous for discretion but slower autofocus limits opportunistic shooting.

Macro Photography

• Canon’s 3cm macro focus allows getting closer to subjects with reasonable sharpness.

• Casio’s 10cm minimum focusing distance restricts macro use, reducing appeal for flower or detail close-ups.

Night and Astrophotography

Both perform poorly beyond ISO 400. No stabilization or advanced exposure tools mean handheld night shots have motion blur unless aided by a tripod.

• Canon supports 720p at 25 fps using H.264 compression, whereas Casio offers 720p at 24 fps but encoded in Motion JPEG, leading to larger file sizes and lower compression efficiency.

• Neither has microphone or headphone ports, built-in stabilization, or advanced exposure controls for video.

Professional and Workflow Considerations

Neither model shoots in RAW, which severely limits post-processing flexibility. For professional use requiring high-quality output and file versatility, these cameras are unsuitable.

Battery life:

• Canon rated at ~210 shots per charge using NB-11L battery, sufficient for casual shooting but less than modern cameras.

• Casio’s battery life isn’t officially rated but likely similar given sensor and design.

Storage:

• Both use SD/SDHC cards, with Casio supporting additional MMC and internal memory - useful for emergency saves.

Connectivity:

• Casio benefits from Eye-Fi compatibility for wireless image transfer, a novelty in its time.

• Canon offers standard USB 2.0 only, with no wireless.
