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.

Pentax 645D vs 645Z Overview and Optics

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.
