Sigma fp vs Sony a1 Sensor Comparison

Usually, it is difficult to envision the gap between sensor dimensions only by reviewing specs. The picture here might offer you a more clear sense of the sensor sizing in the fp and a1.

All in all, both of the cameras come with the identical sensor size but not the same MP. You should anticipate the Sony a1 to offer you more detail as a result of its extra 25 Megapixels. Greater resolution can also let you crop images a good deal more aggressively. The more aged fp is going to be disadvantaged in sensor innovation.
