Panasonic Lumix DMC-GH4 vs Sony a7 Overview and Optics
The Sony a7 emerges as the winner in the optics comparison with a score of 70/100, while the Panasonic Lumix DMC-GH4 scores 52/100. Both cameras share certain specifications, such as having a CMOS sensor type, no image stabilization, and similar processors – the Venus Engine IX for the GH4 and the Bionz X for the a7.
The Sony a7 outperforms the GH4 in several aspects. It has a higher megapixel count of 24 compared to the GH4’s 16, allowing for more detailed images. The a7 also boasts a superior DXOMARK sensor score of 90, as opposed to the GH4’s score of 74, which contributes to the camera’s better overall image quality. Additionally, the a7 features a full-frame sensor size and a 3:2 aspect ratio, further enhancing its imaging capabilities.
On the other hand, the Panasonic Lumix DMC-GH4 excels in shooting speed, capturing 12 frames per second compared to the Sony a7’s 5 frames per second. This makes the GH4 more suitable for capturing fast-moving subjects. Moreover, the GH4 uses a Micro Four Thirds sensor size and a Micro 4/3 lens mount, which allows for a wider selection of lenses and a more compact camera body.
Taking these factors into account, the Sony a7 demonstrates superior optics performance with its higher megapixel count, better sensor score, and full-frame sensor size, making it an ideal choice for photographers seeking high-quality images. However, the Panasonic Lumix DMC-GH4’s faster shooting speed and versatile lens options may appeal to those prioritizing action photography and portability.
