The 523PRO remote control works with both Sony and Canon LANCenabled
video cameras to give you greater control over the zoom functions
of the camera from the pan bar of your video head where you can
also maneuver the camera itself with the same hand.
The main feature of this version is that aside from the record/stop,
focus and power on/standby buttons also found on the 522 LANC
models, it gives you three different zoom speed control buttons.
The unit ships with these buttons as general use presets, but
you can rapidly customize them to your own personal zoom speed
levels!
The zoom speed buttons set the upper limit of the range of movement
of the zoom wheel and determine whether the zoom is progressive
as you exert more pressure on the wheel, or fixed no matter how
far you push the wheel.
Being able to set a fixed zoom speed is an obvious advantage,
since you can cut out the risk of accidentally putting too much
pressure on the zoom wheel and ruining the shot half way through.
The progressive set speed feature is even more flexible: the
zoom wheel in full min-max range has 8 different speed positions,
so as you gradually turn the wheel further, it steps up gradually
from a slow to a rapid zoom. By selecting the lowest zoom speed,
the whole arc of movement that normally covers all speed steps
only covers a few of them, meaning that you can easily keep zoom
limited to a slower range that you might find more suitable for
your subject.
Whether you choose a limited progressive zoom range or a single
fixed speed, the features of the 523PRO mean you can easily repeat
zooms precisely in subsequent takes of the same shot.
