Q: Does the Shake Reduction mechanism work even when using a lens made by another
company?
A: We do not guarantee camera operation (including exposure and focus accuracy) when a lens
made by another company is attached. If it is a K mount, it can be attached, but when using
it at your own risk.
We cannot compensate for any accidents or malfunctions caused by using lenses made by
other companies. Finally, although the SR mechanism itself is performed, the SR effect can
not be guaranteed.
Q: Is it better to always turn on the Shake Reduction (SR)?
A: It is always recommended to turn it on for handheld shooting.
Turn it off when using with the camera fixed on a tripod.
・
When the shooting modes 'B (bulb)' and 'M.UP (mirror lockup)' are selected,
・
SR is automatically turned off.
When using the self-timer or Remote Controller, [Do not turn off automatically] can be selected
・
Q: Is it possible to check the effect of the Shake Reduction (SR) before shooting?
A: You cannot check the SR effect in the viewfinder image, but if you use Live View, you can
check the effect before shooting on the image monitor.
Q: I heard that there is no low-pass filter. Are there any measures against dust on the
image sensor?
A: There is no low-pass filter, but there is an IR cut filter, etc. As a measure against dust, it is
equipped with 'DRll (Dust Removal ll), an image sensor cleaning function that removes dust by
ultrasonic vibration using a piezoelectric element.
