Digital Sensors: Size Matters

Welcome to your Digital Sensors: Size Matters

1. The size of a "full frame" sensor is:

A. The size of the circular image thrown by a 35mm lens.

B. The same size as a single 35mm negative.

C. Approximately 1/2 the size of a 35mm negative.

D. Determined by the focal lenth of the lens.

None

A cropped sensor:

A. Only works with specialty lenses made for cropped sensors.

B Creates a wide-angle effect when compared to a full frame sensor.

C. Captures an image with a 4x5 aspect ratio instead of a 4x6 aspect ratio.

D. Records a smaller image area compared to a full frame sensor.resulting in a telephoto effect.

None
