Optical Image Stabilization The cameras have a comprehensive optical image stabilization system, utilizing an extremely high-precision image stabilization unit incorporated into the lens.

The larger you set the blur amplitude, the larger the motions the camera is expected to be able to attempt to compensate for. For example, if you were holding the camera as steady as you possibly could during a handheld interview, perhaps a setting of "2" would be appropriate.

Setting "2" is a more general-purpose setting. It is designed to combat medium to high-frequency motions, and is probably the best setting for when using the camera handheld. This is the default setting. Setting "3" is optimized to eliminate tiny motions (vibration or subtle handheld shake) while

Programmable Customizable Autofocus and Optical Image Stabilization
°e new AG-UX90 and AG-UX180 camcorders include the ability to program and customize
how the autofocus and image stabilization systems respond.
°is gives you the ability to tailor
the autofocus and/or the image stabilization to be most effective for your particular needs,
or for any given shot.
°is paper will explore the customization options and show you what
is possible, and make some recommendations on what settings may be useful for different
shooting scenarios.
Autofocus
As part of their Leica-certified Dicomar lenses, these cameras have integrated autofocus ca-
pability.
°e autofocus system has been substantially upgraded with the inclusion of a micro-
drive focus unit, which allows for tighter tolerances, finer movements, and faster response
than prior camcorders could do.
°e combination of ultra high definition resolution and a
large 1” sensor require fast response and high precision; not only does the new micro-drive
focus unit accomplish that, but Panasonic went even further by allowing you to customize the
speed and sensitivity of the autofocus system.
°e camera default autofocus system provides suitable performance for a wide variety of typi-
cal shooting needs.
However, while the default settings may serve well for general purposes,
you can definitely significantly improve the focus performance for specific shooting scenarios.
°e programmable autofocus system consists of four menu item settings:
First, there’s an overall on/off setting for the Custom Autofo-
cus system.
If you set “CUSTOM AF” to OFF, then the default
autofocus system will be used.
If you want to take advantage of
your customized settings, you need to set this to ON.
Once you’ve enabled the CUSTOM AF option, the first custom-
izable parameter is AF SPEED.
°is governs how quickly (or
slowly) the autofocus motor works.
°e range is from -5 to +5,
with 0 as the default setting.
Initially you may think that you’d always want this set to the absolute fastest setting (+5) and,
in fact, there are certainly times when +5 works out best.
However, do be aware that the faster
the focus motor drives the lens elements, the more noise you may hear (especially if you’re us-
ing the onboard microphone to record sound).
°e default setting of 0 is a reasonable speed
that is still very quiet.
°e fastest speed (+5) is very quick, and results in a faint increase in
