Pentax 645D vs Sony HX300

In this article, we will be evaluating the Pentax 645D and Sony HX300, former being a Pro DSLR while the latter is a Small Sensor Superzoom by manufacturers Pentax and Sony. There exists a substantial gap among the resolutions of the 645D (40MP) and HX300 (20MP) and the 645D (Medium format) and HX300 (1/2.3") use different sensor dimensions.

Pentax 17 Pre-Orders Outperform Expectations by a Landslide

The 645D was announced 3 years prior to the HX300 and that is a fairly big difference as far as camera technology is concerned. The two cameras offer different body type with the Pentax 645D being a Large SLR camera and the Sony HX300 being a SLR-like (bridge) camera.

Before we go through a in-depth comparison, below is a concise view of how the 645D matches up against the HX300 when considering portability, imaging, features and an overall grade.

Here is a preview of the gallery photos for Pentax 645D & Sony Cyber-shot DSC-HX300. The whole galleries are available at Pentax 645D Gallery & Sony HX300 Gallery.

When you are intending to lug around your camera, you'll have to consider its weight and proportions. The Pentax 645D provides exterior dimensions of 156mm x 117mm x 119mm (6.1" x 4.6" x 4.7") and a weight of 1480 grams (3.26 lbs) and the Sony HX300 has measurements of 130mm x 103mm x 93mm (5.1" x 4.1" x 3.7") with a weight of 623 grams (1.37 lbs).

Remember, the weight of an ILC will change based on the lens you have attached at the time. Following is the front view physical size comparison of the 645D versus the HX300.

Looking at dimensions and weight, the portability grade of the 645D and HX300 is 50 and 63 respectively.

Normally, it is very tough to visualize the difference in sensor measurements only by looking through specifications. The visual underneath will offer you a better sense of the sensor sizes in the 645D and HX300.

Plainly, both of those cameras offer different megapixel count and different sensor measurements. The 645D using its bigger sensor is going to make achieving shallow depth of field less difficult and the Pentax 645D will result in extra detail with its extra 20 Megapixels. Higher resolution will also help you crop pictures a little more aggressively. The older 645D will be disadvantaged when it comes to sensor innovation.
