Panasonic LX100 vs. Ricoh GR: A Deep Dive Into Two Iconic Large Sensor Compacts

In the landscape of large sensor compact cameras, two models stand out for their unique philosophies and enduring appeal: the Panasonic Lumix DMC-LX100 and the Ricoh GR (original model). Both target advanced photographers and enthusiasts seeking high image quality in a pocketable form, yet their design choices and performance metrics diverge meaningfully. After more than a decade testing thousands of cameras across genres, I investigate how these two stack up in practical shooting scenarios, technical capabilities, and workflow integration. This comparison will expose their respective strengths and limitations, clarifying which photographer profiles are best served by each.

Physical Design, Handling, and Ergonomics: Size Isn’t Just a Number

Before evaluating imaging performance, handling characteristics shape the shooting experience fundamentally.

The LX100 and GR both fall in the “large sensor compact” category but with distinct form factor philosophies. The Panasonic LX100 embraces a chunkier, more DSLR-inspired grip and control arrangement, while the Ricoh GR adopts an ultra-slim, minimalist shape emphasizing portability and discretion.

Panasonic LX100

• Dimensions: 115 x 66 x 55 mm
• Weight: 393g

The LX100 feels robust in hand, with a well-contoured grip that facilitates secure hold during longer shoots or in challenging environments. Its top-plate houses clearly marked dials for shutter speed and exposure compensation, supplemented by a lens aperture ring on the fixed zoom lens. This physical feedback benefits manual operation, a frequent requirement for enthusiasts, particularly in controlled studio, portrait, or landscape scenarios.

Ricoh GR

• Dimensions: 117 x 61 x 35 mm
• Weight: 245g

The GR stands out for its almost pocketable thinness, at only 35 mm depth. This sleekness supports rapid grab-and-go street, travel, or candid shooting where conspicuity must be minimized. However, the tradeoff is ergonomics: the minimal grip and compact size reduce hand comfort during extended use or in demanding weather conditions, potentially affecting autofocus stability and steady handling without additional accessories.

Both cameras present an intuitive control placement, but their operating philosophies differ; the LX100’s extra heft and dedicated physical controls cater to deliberate manual adjustments, whereas the GR prioritizes stealth and immediacy at the expense of some ergonomic refinement.

User Interface and Control Layout: Precision vs. Simplicity

Control interfaces are pivotal in maintaining shooting efficiency, especially for professionals.

The Panasonic LX100’s top plate includes dedicated mechanical dials for crucial exposure parameters - shutter speed, aperture ring on the zoom lens, exposure compensation, and a shutter button with a separate on/off switch. This arrangement supports manual exposure workflows well.

In contrast, the Ricoh GR’s controls are restrained to basic buttons and a mode dial, lacking a lens aperture ring due to the fixed focal length. While still precise, the absence of tactile dials requires more dial/menu navigation to adjust aperture or shutter speed, which might reduce speed in time-critical capture contexts.

Back-screen usability further differentiates the two:

• LX100: 3-inch 921k-dot fixed LCD without touchscreen; combined with a high-resolution electronic viewfinder (2764k dots), the camera allows versatile framing, especially under bright light.
• GR: 3-inch 1230k-dot fixed LCD, no touchscreen, and no built-in EVF - relying on the LCD for all composition outside optional external viewfinder use.

The LX100’s integrated high-res EVF combined with physical dials caters to users preferring eye-level shooting and tactile feedback, valuable in fast-paced environments or precise compositions. The GR’s compactness comes at the cost of no integrated viewfinder, pushing reliance onto LCD framing or optional accessories.

Sensor Technology and Image Quality: Micro Four Thirds Meets APS-C

Sensor size, resolution, and underlying technology critically influence image quality, low-light performance, and dynamic range.

The Ricoh GR’s APS-C sensor offers a clear image quality edge over the LX100’s Four Thirds sensor, evident in color depth, dynamic range, and low-light sensitivity. This difference results in cleaner shadows, richer color gradations, and improved noise performance past ISO 800 – a critical factor for night, street, and event photography.

The LX100’s Four Thirds sensor is respectable for the class, enabled by Panasonic’s Venus Engine image processor to produce appealing color and contrast. Its maximum native ISO 25600 is ambitious but rarely practical due to noise levels. However, its optical 24-75mm equivalent f/1.7-2.8 zoom lens offers versatility absent in the GR’s fixed 28mm f/2.8, impacting framing options.

Both cameras implement an antialiasing filter, slightly reducing the risk of moiré in high-detail scenes at the expense of fine texture clarity.

Autofocus Systems: Speed, Accuracy, and Practicality

Autofocus capability strongly affects sports, wildlife, and street photography efficiency.

Neither camera incorporates phase-detection AF, limiting speed vs. newer mirrorless models. The LX100’s 49-point contrast detection performs better in a range of lighting scenarios, enhanced by face detection, critical for portraiture. Its continuous AF with tracking and up to 11fps burst (albeit buffered) facilitates moderately fast action capture.

Ricoh GR’s contrast AF system is simpler, with no face or eye detection and a maximum 4fps burst. This reduces its suitability for fast-moving subjects but works well for street photography where rapid pre-focusing and minimal lag matter more than tracking capability.

Manual focus is accessible on both, though the LX100’s more extensive controls assist critical focusing in macro, portrait, or landscape modes.

Lens and Optical Design: Zoom Versatility vs. Fixed Prime Precision

The Panasonic LX100 sports a 24-75mm equivalent f/1.7-2.8 zoom, while the Ricoh GR employs a fixed 28mm equivalent f/2.8 lens. Each has implications for user adaptability and image rendering.

Panasonic LX100 Lens

• Maximum aperture: f/1.7 at wide, narrowing to f/2.8 at telephoto
• Optical image stabilization (OIS) built-in

The LX100’s zoom range provides photographers with considerable compositional flexibility, from wide environmental portraits and landscapes to moderate telephoto framing for street or travel work. The relatively bright aperture at wide angle aids low-light shooting, while OIS enables steadier handheld shots at slower shutter speeds.

Ricoh GR Lens

• Fixed 28mm equivalent focal length
• Maximum aperture: f/2.8
• No image stabilization

The GR’s fixed wide-angle prime is optimized for sharpness and minimal distortion, essential for street and documentary photography where rapid capture and image detail reign supreme. However, its slower aperture compared to the LX100’s widest f/1.7, plus lack of stabilization, impose limits in low-light environments and narrow depth-of-field applications.

The narrower focal length and subtle barrel distortion translate to a ‘natural’ field of view granting artistic latitude but less framing versatility. Photographers must rely more heavily on physical movement to compose.
