The Pentax 645Z emerges as the winner with a score of 73/100, outperforming the Pentax 645D, which scored 61/100. Both cameras are DSLRs, announced in 2010 and 2014, respectively. They share similar dimensions, with the 645D measuring 156 x 117 x 119mm and weighing 1480g, while the 645Z is slightly larger at 156 x 117 x 123mm and weighs 1550g.
The 645Z surpasses the 645D with a lower launch price of $8499 compared to the 645D’s $9400. However, the 645D has a slight advantage in weight, being lighter than the 645Z. Despite the weight difference, the Pentax 645Z’s higher score and lower price make it a more attractive option for photographers. The Pentax 645D may appeal to those who prioritize a lighter camera, but its lower score indicates that it falls short in overall performance compared to the 645Z.
The Pentax 645Z emerges as the winner in the optics comparison, with a score of 79 out of 100, while the Pentax 645D scores 66. Both cameras share some common specifications, including a medium format sensor size, Pentax 645AF2 lens mount, and the absence of image stabilization.
The 645Z outperforms the 645D in several aspects. It boasts a higher resolution with 51.4 megapixels, compared to the 40 megapixels of the 645D. This allows the 645Z to capture more detail and produce higher quality images. The 645Z also has a faster shooting speed of 3 frames per second, enabling it to capture fast-moving subjects more effectively. Additionally, the 645Z features a CMOS sensor and a Prime III processor, which contribute to its superior DXOMARK score of 101, compared to the 645D’s 82. This indicates better overall image quality and low-light performance.
On the other hand, the Pentax 645D has a CCD sensor, which is known for producing images with richer colors and better dynamic range. However, this advantage is not enough to surpass the 645Z’s overall performance.
In comparing the optics of these two cameras, the Pentax 645Z holds a clear advantage due to its higher resolution, faster shooting speed, and better image quality. The 645D’s CCD sensor does offer some benefits in color and dynamic range, but the 645Z’s superior performance makes it the better choice for most photographers.
When comparing the video capabilities of the Pentax 645D and the Pentax 645Z, it is essential to note that the Pentax 645D does not have any video functionality. Therefore, this comparison will focus on the video capabilities of the Pentax 645Z.
The Pentax 645Z has a video score of 70 out of 100. The camera can record Full HD video with a maximum resolution of 1920 x 1080 pixels. The maximum video frame rate for the 645Z is 60 frames per second, providing smooth and clear footage. Additionally, the 645Z has built-in time-lapse functionality, allowing users to capture stunning time-lapse videos without the need for external equipment or software.
Taking into account the video capabilities of both cameras, it is evident that the Pentax 645Z is the only option for those seeking a Pentax medium format camera with video functionality. The 645Z provides Full HD video recording, a high frame rate, and built-in time-lapse capabilities, making it a solid choice for users who require video capabilities in addition to exceptional image quality.
The Pentax 645Z emerges as the winner in this comparison with a feature score of 59 out of 100, while the Pentax 645D scores 54 out of 100. Both cameras have some common specifications, such as a 3-inch screen for the 645D and a 3.2-inch screen for the 645Z. Neither camera has a touchscreen. Additionally, both cameras have Wi-Fi capabilities but lack GPS and Bluetooth features.
The Pentax 645Z surpasses the 645D with a higher screen resolution of 1,037,000 dots compared to the 645D’s 921,000 dots. The 645Z also has a flip screen, which allows for more versatile shooting angles and better framing of subjects. This feature is absent in the 645D, making the 645Z a more convenient and adaptable choice for photographers.
On the other hand, the Pentax 645D does not offer any significant advantages over the 645Z. Both cameras share similar specifications, with the 645Z simply offering a few additional features that enhance its usability and performance.
Considering these factors, it is evident that the Pentax 645Z is a superior choice for photographers due to its higher feature score, larger screen, and flip screen capability. The 645D, while still a capable camera, does not offer any distinct advantages over its counterpart. Therefore, the Pentax 645Z is the recommended option for those seeking a more versatile and user-friendly medium format camera.
The Pentax 645Z outperforms the Pentax 645D in storage and battery, scoring 65/100 compared to the 645D’s 35/100. Both cameras share the same battery type, D-LI90, and do not support USB charging.
The 645Z has an advantage with its two memory card slots, accepting SD, SDHC, and SDXC cards, while the 645D only has one slot and accepts SD and SDHC cards. This gives the 645Z more storage flexibility and capacity for photographers.
However, the 645D has a longer battery life of 800 shots, compared to the 645Z’s 650 shots. This allows users to take more photos before needing to replace or recharge the battery.
Considering these points, the Pentax 645Z offers greater storage options and versatility, making it the better choice for photographers who require more storage capacity. The Pentax 645D, on the other hand, is more suitable for those who prioritize longer battery life for extended shooting sessions.
