The Fujifilm GFX 100S and the Pentax 645Z are two of the most popular medium format cameras among astrophotographers. Both cameras offer excellent image quality, but they have different strengths and weaknesses. In this blog post, we will compare the two cameras in detail to help you decide which one is right for you.
Image Quality
The Fujifilm GFX 100S has a 102-megapixel sensor, while the Pentax 645Z has a 51.4-megapixel sensor. This means that the GFX 100S can capture more detail than the 645Z. However, the 645Z has a larger sensor, which gives it a slight advantage in low-light conditions.
Dynamic Range
The Fujifilm GFX 100S has a dynamic range of 14 stops, while the Pentax 645Z has a dynamic range of 12 stops. This means that the GFX 100S can capture more detail in both the highlights and shadows of an image.
Color Depth
The Fujifilm GFX 100S has a color depth of 16 bits, while the Pentax 645Z has a color depth of 14 bits. This means that the GFX 100S can produce more subtle gradations of color than the 645Z.
Lens Selection
The Fujifilm GFX 100S has a wider range of lenses available than the Pentax 645Z. This is because the GFX 100S uses the Fujifilm G-mount, which is also used by the Fujifilm X-series cameras. The 645Z uses the Pentax 645 mount, which has a more limited selection of lenses.
Build Quality and Weather Sealing
The Fujifilm GFX 100S and the Pentax 645Z are both well-built cameras. However, the GFX 100S has a more robust build quality and is better weather-sealed than the 645Z. This makes the GFX 100S a better choice for astrophotographers who shoot in harsh conditions.
Price
The Fujifilm GFX 100S is more expensive than the Pentax 645Z. The GFX 100S body-only costs around $6,000, while the 645Z body-only costs around $4,000.
Takeaways: Fujifilm GFX 100S vs Pentax 645Z
The Fujifilm GFX 100S and the Pentax 645Z are both excellent medium format cameras for astrophotography. The GFX 100S has a higher resolution sensor, a wider dynamic range, and a better color depth than the 645Z. However, the 645Z has a larger sensor, which gives it a slight advantage in low-light conditions. Ultimately, the best camera for you will depend on your specific needs and budget.
