Canon PowerShot G1 X vs Casio Exilim EX-ZR300: A Hands-On Comparison for Enthusiasts and Pros

As a seasoned reviewer who has tested thousands of cameras over the past 15 years, I know firsthand how crucial it is to choose a camera that fits your unique photography style and needs. Today, we’re diving deep into two distinctly different compact cameras announced in 2012: Canon’s PowerShot G1 X and Casio’s Exilim EX-ZR300. Both aim to offer high-quality imaging in portable bodies but follow very different design philosophies - large sensor versus superzoom versatility.

In this comprehensive comparison, I’ll share technical insights, real-world performance notes, and practical buying advice to help serious enthusiasts and professionals decide which model suits their photography needs best. Let’s jump in.

Physical Build and Ergonomics: Size Matters, But So Does Comfort

The Canon G1 X is a larger, more substantial compact centered around image quality with a 1.5” sensor. In contrast, the Casio EX-ZR300 favors portability and zoom range, packing a 12.5x zoom into a much smaller shell.

From hands-on testing, the Canon feels more camera-like with a firm grip, well-placed dials, and a reassuringly solid build that’s comfortable even for extended handheld shooting. It weighs 534g and measures 117x81x65mm - noticeable but manageable in a larger jacket pocket or small camera bag.

Casio’s EX-ZR300 weighs just 205g and is significantly slimmer at 105x59x29mm, making it an ultra-travel-friendly companion. The tradeoff is reduced grip comfort and a more plasticky feel. While the Casio fits easily in small bags or pockets, it doesn’t inspire the same confidence for prolonged or rigorous use.

In terms of controls, the Canon features a benefit of manual dials and top-button layouts that feel intuitive.

Canon’s layout includes dedicated rings and buttons for aperture, shutter, and shooting modes - a bonus for users who value speed and customization. Casio opts for a simpler, minimal control array that can slow down advanced manual operations.

Summary: If you prioritize ergonomics and a substantial feel with quick manual access, Canon’s G1 X wins. For compact carry and weight-conscious photographers, Casio’s EX-ZR300 excels.

Sensor Technology and Image Quality: Bigger Sensor vs. Mega Zoom

This is the heart of the matter. Canon uses a large 1.5” CMOS sensor measuring 18.7mm x 14mm, while Casio employs a much smaller 1/2.3” BSI-CMOS sensor at only 6.17mm x 4.55mm. This size difference directly impacts image quality, especially in low light and dynamic range.

From my own lab tests and field shooting:

• Canon PowerShot G1 X: Offers a 14MP resolution with pixels large enough to capture impressive detail and superior color depth (DxOMark color depth score: 21.7 bits). Its optical low-pass filter reduces moiré while maintaining sharpness. Dynamic range performance clocks in at a respectable 10.8 EV, allowing good shadow recovery and highlight retention. Native ISO ranges 100-12800, with usable performance up to about ISO 800 before noise becomes disruptive.

• Casio EX-ZR300: Shoots 16MP but from a sensor area almost 10 times smaller. Despite modern BSI-CMOS tech enhancing sensitivity a bit, image noise at ISO above 400 is quite apparent. Dynamic range is limited, making highlight clipping and blown shadows a challenge with high contrast scenes. Native ISO tops at 3200, but image degradation is severe above ISO 800.

In practical shooting, Canon’s images show richer tonality, smoother gradients, and noticeably better low-light clarity. Casio’s photos can appear oversharpened with more color noise, especially in indoor or evening shots. This is not surprising given the sensor size gulf.

Canon’s files also benefit from RAW support - crucial for advanced editing - whereas Casio lacks RAW output, limiting post-processing flexibility.

Summary: Canon’s large sensor delivers superior image quality with better low light capability and dynamic range. Casio trades image quality for zoom reach and portability but can struggle with noise and detail in challenging lighting.

Autofocus and Shooting Performance: Speed, Accuracy, and Burst

A camera's autofocus (AF) system and shooting speed define how well it performs in action photography genres like wildlife and sports.

• Canon G1 X AF system: Uses 9 contrast-detection points with face detection and tracking. While respectable for 2012, it’s not blazing fast compared to DSLR-level phase detection. AF speed and accuracy were adequate for portraits and casual wildlife but struggled somewhat in fast continuous shooting or low contrast situations. Continuous shooting tops out at 2 fps, which is slow for burst shooting.

• Casio EX-ZR300 AF system: Contrast-detection only with multi-area and center-weighted modes, track focus available but no face detection. AF speed is slower, especially in low light. This limits reliability for fast-moving subjects. Continuous shooting mode details aren’t officially published but are generally slow.

In my testing outdoors on moving subjects, neither camera is ideal for professional sports or fast wildlife action but Canon is definitely more capable for handheld general use and portraits with decent face and eye detection.

Summary: Canon offers the better AF system with face detection and continuous AF for more dependable focusing. Both cameras are limited in burst rates, with Canon still ahead.

Lens and Zoom Capabilities: Flexible Superzoom vs. Quality Standard Zoom

The lenses define usability across photography types.

• Canon G1 X fixed lens: 28-112mm equivalent (4x zoom) with a bright F2.8 aperture upfront, falling to F5.8 at telephoto. Optical image stabilization enhances best image sharpness during handheld shooting, especially in low light. This moderate zoom range suits portraits, landscapes, and street photography well.

• Casio EX-ZR300 fixed lens: Massive 24-300mm equivalent (12.5x zoom) with maximum aperture F3.0-5.9, paired with sensor-shift stabilization. This broad zoom extends creative reach from wide-angle landscapes to telephoto compression and wildlife shooting.

The real-world advantage depends on your priorities.

• For portraits, Canon’s wider aperture and shorter telephoto reach offer better bokeh and subject isolation.
• For wildlife and travel, Casio’s extreme zoom is attractive but at the cost of image quality and sharpness consistency across the range.
• Landscape shooters benefit from Canon’s faster glass and better optics.
• Casio’s macro focus at just 1cm is impressive for close-up work compared to Canon’s 20cm minimum.

Summary: Canon delivers higher lens quality with brighter aperture ideal for portraits and environmental shots. Casio provides versatility with a monstrous zoom, great for travel and wildlife snapshots.

Viewfinder and Screen: Composing Your Shot

An optical or electronic viewfinder impacts framing ability.

• Canon G1 X: Features an optical tunnel viewfinder (no electronic info overlay). It’s small and basic but helpful in bright sun. The main display is a fully articulated 3-inch TFT LCD with 920K dots resolution - a superior screen for composing at odd angles and reviewing images.

• Casio EX-ZR300: Lacks any viewfinder; composition occurs solely on a fixed 3-inch Super Clear TFT screen with 461K dots. This lower resolution and non-articulating screen can limit framing flexibility, especially in bright conditions.

In my experience, Canon’s articulated, high-res screen significantly enhances usability in tricky lighting or shooting positions - important for landscapes and macro work.

Summary: Canon wins easily on display quality and composition flexibility. Casio’s fixed screen is functional but less versatile.

Video Functionality: Quality and Versatility

Modern cameras must cater to hybrid shooters capturing both stills and video.
