Low End Size Sensor Format

Pros of the Low End Size Sensor Format compared to the Full Frame / 36x24 Sensor Format

Costs:
Being a standard feature of any smart phone, the camera is of "zero" costs.
Greater Depth of field:
Due to the very small sensor, the depth of field is great. Snapshots and macro shots benefit from this.

Cons of the Low End Size Sensor Format compared to the Full Frame / 36x24 Sensor Format

Always With You:
A smart phone with its very small "low-end" sensor is always with you. Any other camera reauires extra effort on top to this.
Depth of Field:
Achieving a shallow depth of field is hard to impossible and impacting creative control over focus.
