Canon 1D vs Pentax 645D

Let's look a little more in depth at the Canon 1D vs Pentax 645D, both Pro DSLR cameras by rivals Canon and Pentax. There exists a huge gap among the sensor resolutions of the 1D (4MP) and 645D (40MP) and the 1D (APS-H) and 645D (Medium format) boast totally different sensor measurements.

The 1D was announced 9 years earlier than the 645D which is a fairly significant gap as far as camera technology is concerned. The two cameras feature the same body design (Large SLR).

Before delving into a comprehensive comparison, here is a brief synopsis of how the 1D grades vs the 645D in relation to portability, imaging, features and an overall score.

Below is a sample of the gallery pics for Canon EOS-1D and Pentax 645D. The whole galleries are provided at Canon 1D Gallery and Pentax 645D Gallery.

If you are looking to carry around your camera often, you are going to need to take into account its weight and proportions. The Canon 1D features physical dimensions of 156mm x 158mm x 80mm (6.1" x 6.2" x 3.1") having a weight of 1585 grams (3.49 lbs) while the Pentax 645D has measurements of 156mm x 117mm x 119mm (6.1" x 4.6" x 4.7") and a weight of 1480 grams (3.26 lbs).

Bear in mind, the weight of an Interchangeable Lens Camera will vary based on the lens you are using during that time. Underneath is a front view scale comparison of the 1D against the 645D.

Using dimensions and weight, the portability rating of the 1D and 645D is 50 and 50 respectively.

Normally, it's tough to visualise the gap in sensor sizes just by checking out specifications. The picture here might give you a more clear sense of the sensor sizes in the 1D and 645D.

To sum up, both the cameras feature different megapixels and different sensor sizes. The 1D having a smaller sensor will make getting bokeh more challenging and the Pentax 645D will show more detail with its extra 36 Megapixels. Greater resolution will also make it easier to crop pics way more aggressively. The more aged 1D will be disadvantaged with regard to sensor tech.
