Beautiful, sharp photos with no blurring

Super SteadyShot inside camera body reduces effects of camera shake

Super SteadyShot inside camera body prevents blur by compensating for camera shake

Image stabilisation system operates with all

system lenses

Compensation equivalent to 2-3.5 steps in shutter speed

Operating Tip

Turn on Super

SteadyShot using the

switch on the back of

the camera body.

Super SteadyShot

detects camera

shake and shifts the

position of the CCD

sensor to

compensate for

movement of the

camera body, thus

reducing image blur.

Indicator and warning icon in the

viewfinder provides immediate

indication of camera shake status.

Amount of camera shake is measured on a

scale of 1 to 5 indicator bars. Warning icon

also illuminates whenever the danger of

camera shake is high.

Combats camera shake for sharper

handheld shots every time

Camera shake is one of the most common reasons for spoiled pictures

– and it's particularly noticeable with large prints. To reduce the number

of unnecessarily spoiled photos, the

100 features Super SteadyShot

– a sophisticated image stabilisation system that's built into the camera

body itself. Instead of depending on an anti-shake mechanism within

each lens, Super SteadyShot operates by compensating for small

movements of the CCD image sensor itself. This means that it works

with all compatible Sony

system lenses – and without the need for

expensive specialist optics that include built-in image stabilisation.

The actual compensation effect depends on the selected lens and

shooting conditions, but typically it's equivalent to between 2 and 3.5

steps in shutter speed. As well as reducing the blur caused by camera

shake, Super SteadyShot also permits handheld shooting in situations

that would normally require a tripod or flash. An indicator in the bottom

Effective with all

system lenses

Since it's built into the camera body

itself, Super SteadyShot compensates

for camera shake with all

interchangeable

system lenses.

The result? Shoot with greater

confidence using all compatible optics

including zooms, telephotos, macros and

wide-angles.

Anti-dust system for flawless photos

Banish spotting, speckling and

imperfections that can ruin even the best

shots when dust enters the camera body

as you're changing lenses. The

100

features an advanced anti-dust system

to minimise the effects of dust particles

entering the camera body when lenses

are exchanged. The CCD sensor's anti-

static coating acts as a barrier to dust,

while a CCD vibration function briefly

shakes the sensor every time the

100

is powered off to dislodge dust particles.

There's also a selectable menu function

that vibrates the sensor more strongly.

TECHNICAL POINT

Super SteadyShot allows shutter speeds 2–3.5 steps slower than normal

The fraction 'one over focal length' offers a useful

calculation of the minimum shutter speed (in

seconds) at which sharp images can be obtained

by handheld shooting. Unlike 35mm cameras, the

actual shooting angle of the

100 is equivalent to

the shooting angle of 1.5 times of the focal length

indicated on the lens. For example, a lens with a

focal length of 50mm would have an equivalent

focal length of 75mm, meaning that a minimum

shutter speed of approx. 1/80 sec. would be

required for sharp images. Since Super

SteadyShot provides compensation equivalent to 2

– 3.5 steps in shutter speed, compensation of 2

steps from 1/80 sec. would allow sharp images to

be taken at 1/20 sec., while 3 steps would allow a

minimum speed of only 1/10 sec.
