Pentax 645D vs Sony RX10 II

Here is a complete review of the Pentax 645D and Sony RX10 II, one being a Pro DSLR and the other is a Large Sensor Superzoom by manufacturers Pentax and Sony. There is a big difference between the image resolutions of the 645D (40MP) and RX10 II (20MP) and the 645D (Medium format) and RX10 II (1") use different sensor size.

The 645D was introduced 6 years prior to the RX10 II and that is quite a big gap as far as tech is concerned. Each of the cameras come with different body type with the Pentax 645D being a Large SLR camera and the Sony RX10 II being a SLR-like (bridge) camera.

Before we go straight into a thorough comparison, below is a simple summation of how the 645D grades versus the RX10 II in relation to portability, imaging, features and an overall rating.

Following is a sample of the gallery pics for Pentax 645D and Sony Cyber-shot DSC-RX10 II. The whole galleries are available at Pentax 645D Gallery and Sony RX10 II Gallery.

For anybody who is intending to carry your camera frequently, you will want to take into account its weight and volume. The Pentax 645D has external measurements of 156mm x 117mm x 119mm (6.1" x 4.6" x 4.7") along with a weight of 1480 grams (3.26 lbs) whilst the Sony RX10 II has sizing of 129mm x 88mm x 102mm (5.1" x 3.5" x 4.0") having a weight of 813 grams (1.79 lbs).

In many cases, its hard to imagine the contrast between sensor sizing simply by reviewing specifications. The photograph here will provide you a much better sense of the sensor sizing in the 645D and RX10 II.

Plainly, each of these cameras have got different megapixels and different sensor sizing. The 645D using its larger sensor is going to make achieving shallower DOF simpler and the Pentax 645D will offer you more detail using its extra 20 Megapixels. Greater resolution will enable you to crop images much more aggressively. The older 645D is going to be disadvantaged when it comes to sensor technology.
