Understanding Their Roots: Compact Category and Design Philosophy

Both cameras are compact by design, yet they cater to subtly different user profiles:

• The Casio EX-100 is a small sensor superzoom with a versatile fixed zoom lens (28-300mm equivalent, f/2.8 constant aperture) aimed at those wanting all-in-one flexibility in a pocketable size.
• The Ricoh GR is a large sensor compact with a prime 28mm f/2.8 lens targeting photographers who prioritize image quality, quick handling, and a minimalist approach on the go.

Let's first look at their physical dimensions and ergonomics to understand this better.

As seen in the image above, both cameras are pocket-friendly but noticeably different in shape and heft:

• The EX-100 is chunkier (119x67x50 mm, 389g), reflecting its superzoom lens and larger grip.
• The GR is sleeker and lighter (117x61x35 mm, 245g), emphasizing discreetness and quick reachability.

For gamers of casual pocket shooting versus deliberate photography, this physical difference matters a lot.

Control Layout and User Interface: Hands-On Usability

A camera’s control layout can drastically influence your shooting flow. After extensive shooting sessions, here’s how they compare:

• The Casio EX-100 boasts a comprehensive top-deck with dedicated dials for aperture, shutter speed, and exposure compensation. Its sizable grip adds comfort during long sessions but slightly increases carry weight.
• The Ricoh GR opts for a minimalist top layout with a prominent shutter button and an exposure compensation dial; it lacks dedicated aperture or shutter speed dials but features customizable buttons. Its compact body supports one-handed shooting effortlessly.

For photographers who prioritize manual control and fast adjustments, the EX-100’s tactile dials feel familiar and satisfying. Conversely, the GR’s design invites a more streamlined, less cluttered approach, ideal for street photography where speed and discretion reign.

Sensor and Image Quality: The Heart of the Matter

No comparison is complete without diving into image quality specifics. The sensor technology here defines each camera’s performance envelope.

Sensor Size and Resolution

• Casio EX-100 uses a 1/1.7" CMOS sensor (~7.44 x 5.58mm; 41.5 mm²) with 12 MP resolution.
• Ricoh GR sports an APS-C CMOS sensor (~23.7 x 15.7mm; 372 mm²) with 16 MP resolution.

This sensor size disparity is significant. The APS-C sensor in the GR is nearly nine times larger in area, traditionally linked to better dynamic range, noise control, and shallow depth of field capability.

Hands-On Imaging Observations

• The Ricoh GR consistently delivers crisper images, richer colors, and superior low-light performance, thanks to its larger sensor and excellent image processing pipeline. The raw files offer greater latitude for post-processing - highlighting its pros for professionals and enthusiasts who require image quality over zoom versatility.
• The Casio EX-100 yields sharp photos within its zoom range, with impressive reach and a bright f/2.8 lens helping compensate for sensor size limitations. However, expect higher noise in low-light and more modest dynamic range, typical of smaller sensors.

In summary, if pixel peeping and editing latitude are your priorities, the GR stands out sharply. For travel or event shooters needing focal length flexibility from 28mm wide to 300mm telephoto, the EX-100 offers unbeatable convenience.

Display and Viewfinder Experience: Composing Your Shot

Both cameras lack integrated electronic viewfinders, turning the rear LCD into the primary composing tool.

• The EX-100 includes a larger 3.5" Super Clear tilting LCD with 922k-dot resolution. The tilting mechanism aids shooting at awkward angles, a plus for macro and low/high angle photography.
• The GR features a fixed 3.0" TFT LCD but with a markedly higher 1230k-dot resolution, resulting in slightly better detail rendition. It also supports an optional optical viewfinder attachment for those who prefer eye-level composing in bright sunlight.

During field tests, the EX-100’s tilt screen was more versatile for non-standard compositions, while the GR’s sharper display suited quick image review in any condition.

Focusing System and Performance: Critical for Capturing the Moment

Autofocus efficiency varies based on camera design and intent. Here’s what I experienced:

The EX-100’s 25-point contrast-detection AF with face detection and tracking offers flexible subject acquisition across its zoom range. It achieves quick focus even in reasonable low light, supporting burst shooting up to 30 fps - exceptional for action and wildlife scenarios when paired with the tele zoom.

The GR’s AF system, while reliable under good light, is slower and limited to contrast-detection with no face or eye tracking. Its maximum burst rate is 4 fps, suiting more deliberate shooting styles such as street or landscape.

In practical terms:

• For wildlife or sports photography where speed and tracking are paramount, the EX-100 holds a clear advantage.
• For street, travel, documentary, or landscape where precision rather than speed is key, the GR’s AF is sufficient and precise.

Lens Performance and Photography Use Cases

Let’s expand upon each camera’s lens system and what that means in practical shooting:
