Panasonic Lumix DMC-GH4 vs Sony a7S Overview and Optics

The Sony a7S outperforms the Panasonic Lumix DMC-GH4 in optics, scoring 60 out of 100 compared to the GH4’s 52. Both cameras share certain specifications, such as the CMOS sensor type, lack of image stabilization, and similar processors – the Bionz X for the Sony a7S and Venus Engine IX for the GH4. However, there are distinct differences that give each camera its unique advantages.

The Sony a7S has a higher DXOMARK sensor score of 87, compared to the GH4’s score of 74. This results in better image quality and low-light performance. Additionally, the a7S features a full-frame sensor and Sony FE lens mount, offering compatibility with a wide range of high-quality lenses. The larger sensor size and 3:2 aspect ratio also contribute to its superior image quality.

On the other hand, the Panasonic GH4 has more megapixels (16) and a faster shooting speed (12) compared to the a7S’s 12.2 megapixels and 5 shooting speed. This allows for capturing more detail in images and faster continuous shooting. The GH4 also uses the Micro Four Thirds sensor size and Micro 4/3 lens mount, providing access to a variety of lenses, albeit not as extensive as the Sony FE mount.

While the Sony a7S triumphs in image quality and lens compatibility, the Panasonic GH4 excels in capturing detail and faster shooting. Therefore, the a7S is the better choice for photographers prioritizing image quality and low-light performance, while the GH4 is suited for those seeking higher resolution and faster shooting capabilities.

Panasonic Lumix DMC-GH4 vs Sony a7S Video Performance

The Panasonic Lumix DMC-GH4 emerges as the winner in the video capabilities comparison with a score of 70/100, while the Sony a7S lags behind with a score of 56/100. Both cameras share some common features, such as offering high-definition video recording and manual exposure control.

The Panasonic Lumix DMC-GH4 outperforms the Sony a7S in several aspects. Firstly, it boasts a maximum video resolution of 4K (4096 x 2160) compared to the Sony a7S’s Full HD (1920 x 1080) resolution. This means that the GH4 can capture more details and produce sharper video footage. Furthermore, the GH4 has a built-in time-lapse functionality, allowing users to create time-lapse videos without the need for additional software or equipment.

On the other hand, the Sony a7S has a higher maximum video frame rate of 60fps, compared to the GH4’s 24fps. This allows the a7S to produce smoother video footage, especially in fast-paced scenes or when recording sports events. However, this advantage may not be significant for users who prioritize video resolution over frame rates.

In terms of video capabilities, the Panasonic Lumix DMC-GH4 is the clear winner due to its superior video resolution and built-in time-lapse feature. The Sony a7S, while offering a higher frame rate, falls short in comparison with its lower video resolution and lack of time-lapse functionality. Users looking for the best video performance should opt for the Panasonic Lumix DMC-GH4, while those who prioritize smooth video footage may still find value in the Sony a7S.
