NIKON DX-FORMAT SENSOR
OVERVIEW

ABOUT THE NIKON D5300
DX-format sensors, measuring
approximately 23.6 x 15.8mm (with slight
variations), have been used in every Nikon
DSLR from the D1 onward, until the arrival
of “full-frame” FX-format cameras (e.g. D4,
D800, D610). The sensors in these models
are approximately 36 x 24mm.
The number of pixels on the
sensor has risen from 2.7 million
on the D1 to around 24 million
across the current DX range.
Early models used CCD
sensors, but today CMOS
(Complementary Metal Oxide
Semiconductor) sensors are
used in all of Nikon’s DSLRs.
The DX format dictates a 1.5x
magnification factor, relative to
the same lenses used on 35mm
and FX cameras. The D5300’s
CMOS sensor measures 23.5 x
15.6 mm, making it fractionally
smaller than some other
models, though there’s no real
significance in this. Its 24 million
pixels produce images at a
native size of 6000 x 4000 pixels,
making them suitable for demanding large
prints and book and magazine
reproduction. Dispensing with an anti-
aliasing (optical low-pass) filter helps
sharpness still further.
SHARP SHOOTING
The lack of an anti-aliasing filter
enhances the sharpness of the
D5300’s images, especially with
good lenses and technique.
