Pentax 645D vs Pentax K-30

Let's examine more in depth at the Pentax 645D versus Pentax K-30, one being a Pro DSLR and the other is a Advanced DSLR and both are manufactured by Pentax. There exists a huge gap among the resolutions of the 645D (40MP) and K-30 (16MP) and the 645D (Medium format) and K-30 (APS-C) use totally different sensor dimensions.

Photography Glossary

The 645D was introduced 3 years earlier than the K-30 and that is a fairly significant gap as far as camera technology is concerned. Both of the cameras come with different body type with the Pentax 645D being a Large SLR camera and the Pentax K-30 being a Mid-size SLR camera.

Before delving in to a comprehensive comparison, below is a short summary of how the 645D grades versus the K-30 in regards to portability, imaging, features and an overall grade.

The following is a sample of the gallery pics for Pentax 645D and Pentax K-30. The whole galleries are provided at Pentax 645D Gallery and Pentax K-30 Gallery.

In case you're planning to lug around your camera regularly, you need to think about its weight and proportions.

Remember, the weight of an Interchangeable Lens Camera will vary depending on the lens you have attached during that time. Here is the front view measurements comparison of the 645D versus the K-30.

Taking into consideration dimensions and weight, the portability rating of the 645D and K-30 is 50 and 63 respectively.

Sometimes, it is difficult to visualise the contrast in sensor measurements merely by viewing specs. The graphic below will help offer you a stronger sense of the sensor sizing in the 645D and K-30.

All in all, each of these cameras have got different megapixels and different sensor measurements. The 645D having a larger sensor will make getting shallow depth of field less difficult and the Pentax 645D will render more detail using its extra 24MP. Greater resolution can also make it easier to crop photos much more aggressively. The older 645D will be disadvantaged with regard to sensor technology.
