Do not forget, the weight of an ILC will differ depending on the lens you choose at that moment. Below is the front view overall size comparison of the TG-830 iHS and the DP1.

Using dimensions and weight, the portability score of the TG-830 iHS and DP1 is 91 and 87 respectively.

More often than not, it's hard to visualize the difference between sensor measurements simply by reading specifications. The photograph here should give you a much better sense of the sensor sizes in the TG-830 iHS and DP1.

To sum up, both cameras enjoy different resolutions and different sensor measurements. The TG-830 iHS using its tinier sensor is going to make shooting bokeh harder and the Olympus TG-830 iHS will deliver extra detail using its extra 11MP. Higher resolution can also allow you to crop photographs far more aggressively. The fresher TG-830 iHS provides an edge when it comes to sensor innovation.
