When choosing a mirrorless camera, performance speed is a critical factor for many photographers. The Panasonic G9 II and the Olympus OM-D E-M1 Mark III are two popular options, each with their own strengths. This article compares their speed performance to help you decide which camera better suits fast-paced shooting scenarios.
Camera Specifications Overview
The Panasonic G9 II boasts a high-speed autofocus system, rapid burst shooting, and a robust image processing engine. The Olympus OM-D E-M1 Mark III also features advanced autofocus, high-speed sequential shooting, and a powerful image processor, making both cameras suitable for action photography.
Autofocus Speed and Accuracy
The G9 II uses Depth from Defocus (DFD) technology combined with phase detection, providing near-instant autofocus response. It achieves focus acquisition in approximately 0.02 seconds. The OM-D E-M1 Mark III employs Fast AF with on-chip phase detection, achieving focus in about 0.03 seconds. Both cameras demonstrate excellent accuracy, but the G9 II has a slight edge in speed.
Autofocus in Low Light
In low-light conditions, the G9 II maintains quick focus response thanks to its advanced AF algorithms. The OM-D E-M1 Mark III also performs well but can experience slight delays in dim environments, especially when tracking moving subjects.
Burst Shooting Performance
The G9 II offers high-speed burst shooting at up to 20 frames per second (fps) with continuous autofocus and image stabilization. The OM-D E-M1 Mark III can shoot up to 18 fps with AF tracking enabled. Both cameras excel in capturing fast action, with the G9 II having a marginal advantage in raw speed.
Buffer Capacity
The G9 II has a larger buffer, allowing for approximately 100 RAW images in a single burst before slowing down. The OM-D E-M1 Mark III can handle around 50 RAW images in burst mode. This makes the G9 II more suitable for prolonged high-speed shooting sessions.
Processing and Response Time
The G9 II’s Venus Engine ensures rapid image processing, resulting in minimal lag between shots. The OM-D E-M1 Mark III’s TruePic VIII processor also offers fast response times but may exhibit slightly more lag during continuous shooting sessions.
Startup and Shutter Lag
Both cameras have quick startup times, with the G9 II powering on in approximately 1.5 seconds, and the OM-D E-M1 Mark III in about 2 seconds. Shutter lag is minimal in both models, typically under 0.05 seconds, making them suitable for spontaneous shots.
Conclusion
Overall, the Panasonic G9 II offers slightly faster autofocus, higher burst capacity, and quicker processing speeds, making it ideal for fast-paced photography such as sports or wildlife. The Olympus OM-D E-M1 Mark III remains a strong contender with excellent autofocus and burst performance, but with marginally slower response times. Your choice should depend on your specific needs for speed and shooting style.
