Advanced noise reduction for clearer images
Exmor TM + Bionz TM multi-stage
noise reduction
The employs advanced technologies at every
stage of image acquisition and processing to reduce
the electrical signal noise that can degrade image
quality, especially when taking long exposures or us-
ing high ISO sensitivity settings. When a photo is taken,
the Exmor CMOS sensor's on-chip circuitry suppresses
noise both before and after it carries out analog-to-
digital signal conversion. Within the Bionz image pro-
cessing engine, noise reduction is also applied during
both RAW data conversion and image processing to
ensure an absolute minimum of noise in the final im-
age data. In addition, high ISO noise reduction is auto-
matically applied when shooting at ISO 1600 or more.
Sublime image quality
You can select sensitivity set-
tings from ISO 100 to 3200.
ISO 6400 is also available in
extended ISO mode.
ISO 800
When ISO sensitivity is set to 1600 or
higher, high ISO noise reduction is
automatically activated. (High,
Normal, or Low is user-selectable.)
