Remember that, the weight of an Interchangeable Lens Camera will vary based on the lens you have attached during that time. Following is a front view physical size comparison of the E-450 compared to the K-5 IIs.

Taking into consideration dimensions and weight, the portability grade of the E-450 and K-5 IIs is 77 and 60 respectively.

Quite often, its tough to visualise the difference in sensor dimensions only by going through technical specs. The image below will provide you a more clear sense of the sensor sizes in the E-450 and K-5 IIs.

As you have seen, both the cameras feature different megapixel count and different sensor dimensions. The E-450 because of its smaller sensor will make getting shallow DOF more difficult and the Pentax K-5 IIs will provide more detail as a result of its extra 6 Megapixels. Greater resolution will let you crop pics way more aggressively. The more aged E-450 will be disadvantaged when it comes to sensor innovation.
