Lens barrel controls

Looking at the lens barrel from the left of the camera we see a variety
of controls starting with zoom ring, flash, manual focus and image stabilisation
switch then the main power / record / play dial with the mode sub-dial,
each control is described in more detail below:
Buttons / Switches
 |
Zoom Wide

Zooms towards full wide angle (37 mm), note that the lens ring does
not turn but rather is a proportional spring loaded switch which can
be pushed one way or another. There are two zoom speeds, a slight
twist produces a slow zoom (5.5 secs) a further twist produces a faster
zoom (4 secs). |
 |
Zoom Tele

Zooms towards full telephoto (370 mm). (Otherwise same as above) |
 |
Flash Mode

Toggles through the flash modes: Auto, Redeye Reduction Auto, Redeye
Reduction On, Flash On and Flash Off. (The availability of different
flash modes varies with the selected exposure mode). Flash mode is
displayed on the top LCD and rear LCD (if open). Enabling the flash
will automatically pop it up the next time you half-press the shutter
release or press the AE Lock button. |
| MF |
Manual Focus

Holding down the MF button allows you set a manual focus distance
(in conjunction with the up and down arrows on the 4-way controller)
or re-engage auto focus if already in Manual Focus mode. |
 |
Image Stabiliser

Enable / Disable the optical image stabilisation feature of the Pro
90, we found the stabiliser to be very effective and give you at least
one or two stops more in low light (or at long zoom). |
It's a shame Canon couldn't implement a mechanical zoom ring which is
directly attached to the zoom mechanism inside the lens barrel, this would
produce far better and more accurate control over the lens and allow for
much quicker changes from wide to tele.
Note, there's an annoying 0.6 sec delay between you turning the zoom
ring and the actual zoom beginning.
Exposure Mode Dial
| AUTO |
Automatic Exposure

Camera has complete control over exposure, point-and-shoot operation,
the majority of manual features are disabled, you can't alter exposure
compensation, ISO or use RAW mode. |
| P |
Program Auto Exposure

Very similar to AUTO exposure but you have access to all the normal
manual controls, can set the ISO, exposure compensation, use AE lock,
bracketing etc. |
| Tv |
Shutter Priority Auto Exposure

In this mode you select the shutter speed and the camera will attempt
to select the best aperture for a proper exposure. Shutter speed
is displayed on the LCD, press the left / right arrows to select
different shutter speeds. A half-press of the shutter release causes
the cameras exposure system to calculate the aperture, if it's outside
of the cameras exposure range (for instance trying to take a shot
at 1/500s in darkness) the aperture will appear in RED. The LCD
view changes to reflect the look of the final image at this exposure.
Available shutter speeds (40 total):
1/1000, 1/800, 1/640, 1/500, 1/400, 1/320, 1/250, 1/200, 1/160,
1/125, 1/100, 1/80, 1/60, 1/50, 1/40, 1/30, 1/25, 1/20, 1/15, 1/13,
1/10, 1/8, 1/6, 1/5, 1/4, 0.3, 0.4, 0.5, 0.6, 0.8, 1, 1.3, 1.6,
2, 2.5, 3.2, 4, 5, 6, 8 secs

| Av |
Aperture Priority Auto Exposure

In this mode you select the aperture and the camera will attempt
to select the best shutter speed for a proper exposure. Aperture
is displayed on the LCD, press the left / right arrows to select
different apertures. A half-press of the shutter release causes
the cameras exposure system to calculate the shutter speed, if it's
outside of the cameras exposure range the shutter speed will appear
in RED. The LCD view changes to reflect the look of the final image
at this exposure. Available apertures:
Wide: F2.8, F3.2, F3.5, F4.0, F4.5, F5.0, F5.6, F6.3, F7.1, F8.0
Tele: F3.5, F4.0, F4.5, F5.0, F5.6, F6.3, F7.1, F8.0
|
| M |
Full Manual Exposure

In this mode you select the aperture and the shutter speed from any
combination of the above. Left and right arrows select shutter speed,
up and down arrows select aperture. The LCD view changes to reflect
the look of the final image at this exposure. It appears as though
the Pro90's metering system is disabled in this mode as there's no exposure
meter as seen on other cameras. |
 |
Pan-focus

In this mode the focal length is locked to maximum wide angle (you
cannot zoom). No auto focus is performed, instead the focus is locked
(much like a fixed focus lens camera) which allows very fast (almost
lag free) shots to be taken. Useful for situations when you need a
fast reaction. |
 |
Portrait

In this mode apertures are kept as large as possible (small F
number) to produce a blurred background to help define the subject
in a portrait shot. |
 |
Landscape

In this mode the flash is by default disabled (although you can
enable it) and focus is locked at infinity. Apertures are kept as
small as possible (large F numbers) to produce the largest possible
depth of field. Macro focus is also disabled. Designed to be used
for taking landscape shots. |
 |
Night Scene

Known on other cameras as "Slow Sync Flash". Put simply
in this mode slow shutter speeds are used to capture a dimly lit background
(buildings at night for example) and the flash fires briefly to illuminate
a foreground subject. |
| BW |
Black & White

Shoots in black & white. |
 |
Stitch Assist

Designed to make shooting of panorama / stitch shots easier. You
have a choice of five different stitch modes: left-right, right-left,
down-up, up-down or 4-frames in a square. The display changes to show
previously shot frames in the sequence to help alignment of each frame.
Exposure and White Balance are locked to the first frame. |
 |
Movie Mode

Shoot short (up to 30 second) movie clips @ 320 x 240. Audio is
also recorded. |
Again, as with the G1, there's a very good range of exposure modes which
makes the Pro90 a camera which can be used by the beginner, keen amateur
and prosumer alike. A good range of shutter speeds, apertures and ISO's
means that you should be able to shoot just about any type of shot in
just about any situation.
1/1000 sec shutter speed
Once again the Pro90 uses a single iris mechanism for
both aperture and shutter (close of shutter), luckily the situation isn't
as complex as with the G1, put simply you can't use a shutter speed of
1/1000 sec and any aperture larger than F4.
