Its larger surface also excels in dynamic range and low-light performance, offering cleaner shadows and highlight recovery. The ISO can be pushed down to an ultra-low 6 or ramped to 102,400, useful for advanced exposure experimentation.

Image Quality in Practice

• Dynamic Range & Detail: The Sigma’s full-frame sensor provides roughly 1.5 to 2 stops wider dynamic range, critical for landscape and portrait shooters craving rich tonal gradation. The Olympus OM-5 holds its own, but shadows contain more noise and highlight roll-off is slightly faster due to the sensor size.

• ISO Performance: Thanks to backside illumination and a bigger sensor, the fp L yields cleaner high-ISO images and greater detail retention, indispensable in night photography and fast-action low-light shooting.

• Raw and Processing: Both cameras support versatile RAW formats, but Sigma’s large RAW files demand greater computing power and storage.

Whether crispness or portability is your priority will steer this choice decisively.

Autofocus Systems: Speed, Accuracy, and Tracking

Autofocus can make or break moments, especially in fast genres like sports or wildlife. Both cameras utilize hybrid AF systems with phase-detect and contrast-detect points, but their implementations differ.

The OM-5 excels in autofocus versatility with a dense 121-point system, delivering precise subject tracking in continuous AF mode. Its advanced contrast-detection complements phase detection to lock focus quickly, aided by robust face and eye detection - useful for portrait and candid street photography.

The fp L's 49 points focus slower in challenging focus conditions, more so with Sigma's relatively small lens lineup. However, it gains from a larger sensor’s depth of field control, enabling finer manual focus precision, especially when combined with focus peaking and magnification.

Real-World AF Performance

• Sports and wildlife: The Olympus OM-5 leads due to faster, more reliable tracking, and benefits from a 10fps burst rate plus an electronic shutter capable of 1/32000s - a boon for fast-moving action in bright light.

• Portraiture: Both cameras’ face and eye detection perform well, but the OM-5 can maintain focus better in dynamic shooting thanks to its sophisticated AF algorithms.
