Both were released in the early 2010s, targeted at casual to enthusiast photographers wanting more than smartphone snaps. But how do they truly stack up when scrutinized through the lens of today’s photography standards - across portrait, landscape, wildlife, and myriad other genres?

In this comprehensive comparison, drawing from my extensive experience testing thousands of cameras, I dive into every critical aspect you need to consider. From sensor technology to ergonomics, autofocus sophistication to video capabilities, I'll break down what genuinely sets these two apart - helping you make an informed choice aligned with your photographic aspirations and practical needs.

Getting to Know the Players: Quick Specs Overview

Before diving into the nuances, here is at-a-glance data to keep in mind:

The Casio EX-10 is notably larger and heavier, reflecting its ambition as a more capable advanced compact. The Nikon S6100 opts for ultraportability at the expense of features and flexibility, finding its place in simple travel or snapshot use cases.

Sensor and Image Quality: The Core of Your Photos

A standout differentiator is the sensor technology and size. Casio equips the EX-10 with a 12MP 1/1.7" CMOS sensor, larger than the Nikon’s 16MP 1/2.3" CCD sensor. While the Nikon’s higher pixel count offers a larger file size, sensor size and type are far more significant to image quality than pure megapixels.

Why does the sensor matter?

• Sensor Size: Larger sensors capture more light, crucial for noise performance, dynamic range, and overall image clarity.
• Sensor Type: CMOS sensors, as in the EX-10, generally outperform CCDs in speed, low light, and power efficiency.
• Megapixels: More megapixels mean potential for higher detail but often at the cost of pixel size and noise, especially on small sensors.

In real-world testing, the EX-10 consistently delivers cleaner images above ISO 400, retaining nuanced shadow detail and smoother gradations. The Nikon S6100's CCD sensor exams show increased noise and reduced dynamic range in low-light and high contrast scenes, particularly ISOs beyond 400. However, its 16MP resolution allows tight cropping in good light, albeit with noise penalties.

Both cameras apply an anti-aliasing filter, which minimizes moiré but may soften micro-detail slightly. The EX-10’s inclusion of RAW file support is a huge plus, offering powerful post-processing flexibility to harness its sensor advantages fully. The Nikon S6100 lacks RAW capability, locking users to JPEG compression with limited editing scope.

Lens and Aperture: Optical Flexibility vs. Brightness

The EX-10 features a bright, fast lens ranging from a modest 28-112mm equivalent focal length with a top aperture of f/1.8 at wide angle. The Nikon's S6100 offers an extended zoom reach from 28-196mm but with slower optics (f/3.7–5.6), restricting low-light shooting and depth-of-field control.

This distinction translates into:

• Portraits: The EX-10’s wider aperture allows for a shallower depth of field - smoothing backgrounds to isolate your subject with creamier bokeh. Its fast lens is ideal for well-lit portraits and indoor shooting without a flash.
• Telephoto performance: Nikon’s S6100 shines when needing longer reach, useful for casual wildlife or candid street photography, but at the trade-off of less light entering the lens, making autofocus slower and noisier.
• Macro focus distance: The Casio’s ability to shoot as close as 1 cm beats Nikon’s 3 cm minimum, catering better to macro enthusiasts or close-up details.

For your shooting needs, if low-light or portraiture is your focus, the EX-10’s fast lens will prove a versatile tool. If you value zoom reach for casual telephoto shots, the S6100 covers that end better.

Autofocus and Performance: Speed and Precision in Action

Autofocus (AF) systems in compact cameras can vary wildly, and this is where the EX-10 and S6100 differ sharply:

The EX-10’s continuous and tracking AF allow better performance for moving subjects - wildlife and sports photographers will appreciate the 10fps burst rate for capturing fleeting moments. Conversely, the Nikon’s AF is geared toward still subjects, with a slower single-shot rate making it less suitable for fast action capture.

In our testing, the EX-10’s touch AF also significantly speeds focus acquisition and helps rack focus smoothly in video mode - an area where the S6100 lags with no continuous AF or manual exposure control.

Build, Handling, and User Interface: Feel the Difference

The Casio’s larger 3.5" Super Clear tilting touchscreen LCD with a high-resolution 922k-dot display offers great flexibility for shooting at awkward angles and reviewing photos in detail. The 180-degree upwards tilt appeals to vloggers and selfie enthusiasts, even if the EX-10 lacks a dedicated front-facing screen mode. The touchscreen supports intuitive focus point selection and menu navigation.

The Nikon S6100 sports a smaller, fixed 3.0" TFT touchscreen with 460k-dot resolution - adequate but limiting for waist-level or overhead shooting. Both cameras omit electronic viewfinders, relying solely on LCD framing.

From a handling perspective:

• Casio EX-10: The larger grip and more robust body instill confidence and ergonomic comfort during extended shoots. Physical control buttons and manual exposure modes empower more advanced creative control.
• Nikon S6100: Extremely pocketable at 175g and slim dimensions, it fits discretely in a jacket or purse, ideal for street photographers prioritizing stealth and light travel gear.

Neither offers weather sealing, so plan accordingly if shooting in challenging environments.

Battery and Storage: Powering Your Creative Sessions

Battery life is essential for uninterrupted shooting:

Here, the EX-10 shines with more than twice the endurance, reducing the need to carry backups for full-day shoots. Both cameras support common SD card formats, giving you ample flexibility and the option to purchase high-speed cards for quicker write times on the EX-10’s RAW files.

Video Capabilities: Capturing Motion with Confidence

Though not primary video cameras, their capabilities merit a look:

• Casio EX-10: Offers Full HD 1080p recording at 30fps with H.264 compression. Optical image stabilization reduces shake during handheld video. Unfortunately, the camera lacks microphone or headphone jacks, limiting sound quality control.
• Nikon S6100: Limited to 720p HD at 30fps with Motion JPEG file formats, resulting in larger files and fewer editing options.

For creators wanting to shoot vlogs or motion-heavy content, the EX-10 delivers more professional results and flexibility, though both lack key video-centric features of current market favorites.
