Fujifilm GFX 100s vs Pentax 645Z

When comparing Pentax 645Z and Fujifilm GFX 100s, which one is better?

1. Internal Raw Recording



Winner: Tied — Neither have this feature

Regarding internal raw recording: The ability to record raw video internally is found in cameras such as Blackmagic models. It takes up more storage space but is also more flexible afterwards. We don't think internal raw video recording is a requirement.

2. Resolution

Fujifilm GFX 100s wins in terms of megapixels, with 102 MP megapixels compared to 51.4 MP megapixels on the Pentax 645Z49.61% fewer.

Winner: Fujifilm GFX 100s

Regarding resolution: The camera's resolution is specified in megapixels where a higher value means more data than a lower value. This doesn't mean that the camera with the most megapixels is best, but it can be interesting to compare them.

3. Interchangeable lenses



Winner: Tied — both have this feature

Regarding interchangeable lens: A system camera has what are called interchangeable lenses, where you can swap lenses depending on what you're going to photograph. However, this doesn't mean that all cameras have interchangeable lenses; a compact camera usually has a built-in lens that can't be changed. What suits you best is entirely up to you — do you want a small and convenient camera, or a larger and more adaptable one?
