The a6300 includes an anti-alias filter providing smoother, moiré-free images but slightly less edge acutance.

Conclusion: For photographers whose priority is ultimate image quality - especially in low light and landscapes - the Sony APS-C sensor is advantageous. The Olympus sensor is competent but optimized for compactness and creative social photography rather than pixel peeping.

Autofocus Systems: Precision and Speed Realities

Autofocus performance is critical when shooting dynamic subjects, portraits, or wildlife.

• Olympus E-P7: Features a contrast-detection autofocus system with 121 focus points, including face detection and tracking, but lacks phase detection. This system performs well in good light but shows less reliability in fast action or low contrast areas. Notably, it does not support animal eye autofocus, which limits wildlife portrait applications.

• Sony a6300: Equipped with a hybrid AF system incorporating 425 phase-detection points alongside contrast detection, the a6300 provides exceptional speed and accuracy. It excels in continuous autofocus mode with excellent subject tracking, making it ideal for sports and wildlife photography. While it doesn't have animal eye autofocus (a later Sony feature), it remains highly capable.

Both cameras offer continuous AF and face detection, but Sony’s advanced phase detection translates into noticeably better performance for moving subjects and focus acquisition speed, a critical difference that shows up in real shooting circumstances.

Image Stabilization and Exposure Control

The Olympus E-P7 incorporates sensor-based 5-axis image stabilization, a major benefit for handheld video and low-light stills, especially given the lack of IBIS in many competing models at its price point. Stabilization significantly aids macro photography and travel shooting where tripods aren’t always convenient.

The Sony a6300 lacks in-body image stabilization, relying instead on optical stabilization within certain lenses. This is a drawback for users who shoot handheld video or in unstable environments, where Olympus’s IBIS actively compensates for shake.

Both cameras provide standard exposure modes: manual, aperture priority, shutter priority, and offer exposure compensation. The Olympus’s shutter speeds max out at 1/16000s electronic shutter, useful for bright conditions and fast action, exceeding the Sony’s 1/4000s max mechanical shutter speed.

Video Capabilities: Who’s Better for Moving Pictures?

The Sony a6300 was among the first in its class to offer 4K video recording at 30p (3840 x 2160) with full pixel readout and no pixel binning, producing remarkably clean footage for its era. Codec options include MPEG-4, AVCHD, and XAVC S, catering to professional workflows. It also supports slow-motion Full HD at 120 fps, adding creative versatility. There’s a microphone input port, though no headphone jack, which allows better audio control.

Conversely, the Olympus E-P7 mirrors the 4K 30p capability but lacks a microphone input, which limits professional audio recording options. It produces 4K video at 102 Mbps, using H.264 codec (MPEG-4 container), sufficient for casual to enthusiast use, but it misses slow-motion options above 60 fps at Full HD.

Neither camera offers in-body 4K stabilization, but Olympus’s 5-axis stabilization significantly helps reduce handheld video shake, giving it a slight edge for run-and-gun shooters focused mainly on casual video or vloggers without external microphones.
