Key Advantages
The 51.4MP medium format CMOS sensor delivers superior image detail and dynamic range compared to full-frame DSLR sensors. The camera's robust weather-sealed body allows shooting in harsh conditions without worry. Shake Reduction sensor-shift technology reduces blur, enabling sharper handheld shooting. The SAFOX 11 autofocus system with 27 cross-type points provides fast, precise focusing. Dual SD card slots offer flexible storage options for backup or overflow shooting. Pixel Shift Resolution enhances color accuracy and image sharpness beyond the native sensor resolution.
Limitations
Compared to modern mirrorless and medium format models, the 645Z has a relatively slow continuous shooting rate of around 3fps, which limits use for fast action photography. The autofocus system, though reliable, is less advanced than newer hybrid or phase-detection systems used in current cameras. Video capabilities are limited to Full HD with no 4K support. The camera offers a relatively heavy and bulky body compared to compact mirrorless systems. Lack of in-body Wi-Fi or Bluetooth connectivity requires physical cable connection for data transfer. Battery life is good but can be improved compared to newer energy-efficient models.
