Question

What is the mention of 'Fx" and 'DX' in Nikon Digital cameras?

Answer 1

FX is full-frame sensor that is the same size as a 35mm film frame. DX is an APS size sensor that is somewhat smaller compared to the full-frame, but both are used in DSLR's. With the DX, there is a crop factor in the lenses due to the chip size.

Answer 2

Dx - The Nikon DX format is an image sensor format of approximately 24×16 mm. Its dimensions are about 2/3 those of the 35 film format (29mm vs 43mm diagonal, approx.). The format was created by Nikon for its digital SLR cameras, many of which are equipped with DX-sized sensors.

Fx - A full-frame digital SLR is a digital single-lens reflex camera fitted with an image sensor that is the same size as a 35 mm (36x24 mm) negative.

Answer 3

The terms relate to the size of the sensor. FX is considered a "full-sized" sensor, it is the same size as a 35mm film plane. DX is the typical digital sensors that are somewhat smaller, I don't know the size exactly, I'm sure someone here does. The smaller lens causes a "crop factor" which changes the apparent image magnification size for a given lens. For a 35mm or FX camera a 50mm is considered "normal", which is no apparent magnification, the image appears as you would see it. For a DX a 35mm is closer to a "normal" perspective and a 50mm would give a slight telephoto effect.
