Sony TX30 vs Sony A33 Sensor Comparison

Sometimes, it's tough to imagine the contrast in sensor sizes just by researching specs. The picture here will help give you a far better sense of the sensor sizes in the TX30 and A33.

All in all, both of the cameras posses different megapixel count and different sensor sizes. The TX30 with its smaller sensor is going to make achieving shallower DOF more difficult and the Sony TX30 will provide you with more detail using its extra 4 Megapixels. Higher resolution will let you crop pictures somewhat more aggressively. The newer TX30 should have a benefit with regard to sensor tech.
