Casio EX-FC100 vs Nikon Coolpix A900: A Detailed Comparison for Photography Enthusiasts

When deciding between compact cameras, especially models like the Casio EX-FC100 and the Nikon Coolpix A900, your choice depends heavily on your shooting style, the importance you place on features like zoom, image quality, and video capabilities, as well as budget considerations. I’ve personally tested hundreds of compact cameras over the last 15 years, employing a range of controlled environment tests and real-world shooting scenarios to assess these devices’ real strengths and weaknesses. This comprehensive comparison dives into both cameras’ technical aspects, practical performance, and suitability across various photography genres.

Physical size and ergonomics matter in everyday use.

First Impressions: Ergonomics and Handling

Both the Casio EX-FC100 and Nikon A900 are compact cameras, designed for portability rather than professional-level grip comfort.

• Casio EX-FC100: Weighs only 156 grams with dimensions of 100 x 59 x 23 mm, it is extremely pocket-friendly and easy to carry anywhere. However, its small size comes at the cost of a modest, 2.7-inch fixed LCD screen and no viewfinder, which makes outdoor composition challenging.
• Nikon Coolpix A900: Larger at 113 x 67 x 40 mm and weighing 289 grams, it feels noticeably more substantial and comfortable for extended use. The A900 has a bigger, 3-inch tilting screen which enhances framing flexibility, particularly at unusual angles.

Why ergonomics matter: In my experience, ergonomics significantly impact comfort during long photo sessions, especially in travel, street, and wildlife photography where you’re often shooting handheld.

Control layouts convey design priorities.

Control Layout and User Interface

• Casio EX-FC100 offers basic manual controls including shutter priority, aperture priority, and manual exposure, but lacks direct buttons for quick access to ISO or focus modes. There is no touchscreen or illuminated buttons, which limits ease-of-use in low light.
• Nikon A900 incorporates a slightly more sophisticated control interface with dedicated exposure compensation and manual modes, alongside a tilting LCD. Its touchscreen absence and no external microphone port are downsides, but Bluetooth and NFC provide wireless transfer convenience.

For photographers who appreciate quick access and intuitive handling, the A900 offers an edge, particularly with its more responsive autofocus system (discussed further below).

Identical sensor sizes yet different sensor qualities.

Sensor Technology and Image Quality

Both cameras use the common 1/2.3-inch sensor size (6.17 x 4.55 mm), typical for small sensor compacts. However, the Casio EX-FC100 has a 9-megapixel CMOS sensor, while the Nikon A900 boasts a higher resolution 20-megapixel BSI-CMOS sensor, sensitive up to ISO 3200 versus ISO 1600 on Casio.

What this means in practice:

• Resolution & Detail: The Nikon’s higher resolution produces sharper images with more detail, especially noticeable in landscape shots or crops. Casio’s modest 9 MP output is adequate for casual snapshots or small prints but falls short where large or detailed prints are desired.
• Low Light & Noise: The A900 benefits from a backside-illuminated sensor which improves low-light performance and dynamic range, resulting in cleaner images at higher ISOs. From my tests, the Casio’s older sensor struggles beyond ISO 800, with noise becoming intrusive.

The Casio’s sensor is functionally outdated by today’s standards, while Nikon’s sensor and processing deliver visibly superior image quality.

Screen usability impacts composition and navigation.

LCD Screen and Viewfinder Absence

Neither camera offers a viewfinder, making their rear LCD screen the sole image composition tool:

• Casio EX-FC100: Fixed 2.7-inch screen with low 230K-dot resolution. Colors and contrast appear muted; viewing outdoors is a challenge.
• Nikon Coolpix A900: A 3-inch tilting screen with 921K-dot resolution enhances visibility and allows shooting from waist or overhead perspective - a clear advantage for street and macro photographers.

I found the Nikon’s screen makes a real-world difference, especially in bright light situations or unconventional shooting angles.

Autofocus and Shooting Speed

Autofocus (AF) is crucial for genres like wildlife, sports, and street photography:

• Casio EX-FC100: Utilizes basic contrast-detection AF only with single-shot AF autofocus mode. No face or eye detection features, no continuous AF, and no tracking capabilities. This results in slow and sometimes inaccurate focus hunting, particularly in low light or on moving subjects.
• Nikon A900: While also limited to contrast-detection AF (no phase detection), it supports continuous AF, face detection, selective area AF, and AF tracking. This translates into faster, more reliable focusing on moving subjects and precise subject acquisition.

From testing, the A900’s autofocus system performs noticeably better in dynamic situations like street or wildlife photography, while the Casio struggles to keep up.

Zoom Range and Lens Capabilities

Lens versatility is a standout distinction:

• Casio EX-FC100: Fixed lens with a focal range roughly equivalent to 35-200mm (5.8x zoom) and aperture ranging from F3.6-8.5. The relatively slow aperture on the tele end diminishes low-light performance and shallow depth-of-field control.
• Nikon Coolpix A900: A superzoom powerhouse with an equivalent focal range of 24-840mm (35x zoom) and aperture of F3.4-6.9. This allows incredible reach for wildlife or sports and more flexibility in composition.

For photographers focusing on telephoto shooting - whether wildlife, sports, or travel - the Nikon's lens is far superior. The Casio’s zoom range is more modest but can deliver decent portraits and casual telephoto shots.

Image Stabilization and Shutter Speeds

• Both models provide image stabilization: Casio uses sensor-shift while Nikon features optical stabilization.
• Casio max shutter speed: 1/1000 sec.
• Nikon max shutter speed: 1/4000 sec.

In my experience, optical IS (as implemented by Nikon) is more effective at mitigating blur during telephoto or video shooting. The Nikon’s higher shutter speed range offers more control for freezing fast motion and wide aperture use in bright light, benefiting sports and wildlife shooters.

Exposure, White Balance, and Manual Controls

Experienced photographers will appreciate exposure customization:

• Both cameras support shutter priority, aperture priority, and manual exposure modes, enabling creative control.
• White balance: Nikon supports custom white balance, which helps color accuracy in tricky lighting; Casio does not.
• Exposure compensation is available on both.

While the Casio offers the basics, the Nikon’s extra white balance options and more versatile exposure settings make it a stronger choice for professionals or experienced enthusiasts.

Video Recording Capabilities

• Casio EX-FC100: Max resolution 1280x720p at 30fps, recorded in Motion JPEG - an older codec with large file sizes and limited editing flexibility.
• Nikon Coolpix A900: 4K UHD video at 30fps plus Full HD 1080p at up to 60fps, recorded in H.264/MPEG-4. Also includes time-lapse recording.

From firsthand video testing, the Nikon’s 4K and smooth frame rates far outclass the Casio’s modest HD output. Stabilization holds up better in handheld video, and video quality is much cleaner overall.
