Sensor Architecture and Image Quality: Resolution, Dynamic Range, and Noise

Evaluating image quality requires scrutiny of sensor size, resolution, and processing prowess. The FH22 employs a 1/2.3" CCD sensor measuring 6.08 x 4.56 mm with a surface area around 27.72 mm² and an effective resolution of 14 megapixels. The LX7 boasts a larger 1/1.7" CMOS sensor at 7.44 x 5.58 mm (~41.52 mm²) with a 10 megapixel count. While the FH22 offers higher nominal resolution, the sensor technology and size matter more for ultimate image quality.

CCD sensors, traditionally favored for color depth and low noise, struggle to keep pace with modern CMOS sensors, especially in dynamic range and ISO performance. The LX7’s sensor benefits from backside illumination (BSI) and more advanced Venus Engine processing, yielding wider dynamic range (measured DxOMark DR ~11.7 EV) and superior noise control at elevated ISOs. With a larger pixel pitch due to fewer megapixels spread over a bigger sensor area, the LX7 offers richer tonal gradation and cleaner shadows in demanding lighting.

In contrast, the FH22’s smaller sensor and older CCD architecture severely limit dynamic range, struggle with noise beyond ISO 400, and deliver images suited primarily for casual viewing or small prints.

Display and User Interface: Touchscreen Versus Higher Resolution LCD

Both cameras feature a 3-inch rear LCD, but the comparison reveals marked differences in interface responsiveness and clarity.

The FH22 offers a modest 230k-dot touchscreen LCD. Despite the touchscreen functionality enabling basic framing and menu navigation, limited resolution restricts critical focus checking or fine detail evaluation during playback. The touchscreen, while promoting casual ease of use, lacks precision for advanced control.

The LX7 includes a non-touch, fixed 3-inch TFT color LCD with an impressive 920k-dot resolution. This elevated pixel density provides a much clearer and detailed preview, essential for manual focus confirmation and exposure evaluation in the field. Although touchscreen interaction is absent, physical buttons and dials provide a dependable tactile interface under varied shooting conditions.

Neither camera features built-in viewfinders by default, but the LX7 supports an optional electronic viewfinder for enhanced composition in bright environments.

Autofocus System: Speed, Accuracy, and Tracking Capabilities

Effective autofocus (AF) performance is critical to satisfying results, especially when photographing dynamic subjects.

The FH22 utilizes a basic contrast-detection system with just 9 focus points and no face detection or tracking functionality. Autofocus speed is relatively slow, and the lack of tracking or continuous AF limits usability for moving subjects. This system is adequate for stationary or landscape subjects under good light but often frustrating in fast-paced scenarios.

The LX7, while still limited to contrast-detection AF (no phase-detect pixels), significantly improves with 23 AF points and advanced face detection aiding precision focus. It supports continuous AF and tracking modes, enabling more reliable subject acquisition in varied conditions. In practical field tests, the LX7's AF system was noticeably quicker, more consistent, and better at maintaining focus on moving subjects, though it still cannot quite match modern hybrid AF systems found in later cameras.

This difference makes the LX7 suitable for moderate action photography, including street and some wildlife shooting within telephoto reach, whereas the FH22 functions better as a casual or travel compact with no real expectation for speed or subject tracking.

Burst Shooting and Shutter Performance

Frame rate and shutter speed ranges also reflect the targeted user experience.

• FH22 offers a continuous shooting speed of ~5 FPS, with shutter speeds from 1/60 sec up to 1/1600 sec. Lack of electronic or silent shutter modes limits versatility in quiet or difficult lighting environments.

• LX7 increases burst speed to 11 FPS, doubling the shutter speed range maxing at 1/4000 sec, allowing better capture of fleeting moments and handling bright sunlight with open apertures. This capacity facilitates sports or wildlife shooters seeking high capture rates.
