Design

The S30 / S40 represented was a new design angle for Canon, a long thin body with a sliding lens cover. It appears that this design as proved popular and Canon have stuck with the S40's body, lens, LCD and control layout with the advent of the new S45. The front and top of the camera sport a 'brushed metal' strip, the rest of the camera is made from metal (apart from battery cover, buttons etc.).

The sliding lens cover is also the power switch, open it fully and the camera will power up, lens extends, push it towards the lens and the camera will power off, lens retracts. You can't close the lens cover on the lens as you can't move it past a set position until the lens has retracted.

Other distinctive design features include the super-slim flash window and single (integrated) battery and compact flash compartment. At the back of the camera it's worth noting the shooting priority play switch, flipping this switch to the right enters play mode, a half-press of the shutter release always returns it to shooting mode.

Holding the S45 to shoot it is surprisingly comfortable, despite the lack of a 'proper' hand grip at the front, the camera is still deep enough to feel steady in your hand. The thumb recess moulded into the back of the camera aids grip and stops the camera from tipping anticlockwise. The second 'in hand' shot above gives you an impression of the S45's size and proportions.

LCD Monitor (rear)

The S45's 1.8" LCD sits behind a protective plastic cover, unfortunately Canon haven't blessed it with the excellent anti-reflective coating seen on other digital cameras. That said the LCD is fairly bright and sharp and provides plenty of feedback. Through the setup menu you can select two levels of backlight brightness (obviously the brighter of the two will have an affect on battery life).

Viewfinder

A standard 'optical tunnel' style of viewfinder and there's no dioptre adjustment. Through the viewfinder you'll see central aiming brackets which also correspond (roughly) to the edge of the focus points. There are also no parallax correction lines which would assist framing at close distances. The viewfinder provided approximately 84% frame coverage. My advice; get used to using the LCD monitor.

The two lights beside the viewfinder indicate the following:

The Green Steady (Good AF) and Yellow Flashing (Bad AF) indications are now repeated on the main LCD in the colour the selected focus area bracket turns after the AF has finished.

Battery / Compact Flash Compartment

On the base of the camera you'll find a single compartment door behind which are found the Compact Flash slot (Type I or II; Microdrive supported) and the battery slot which takes the NB-2L 7.2V, 570 mAh (3.9 Wh) Lithium-Ion rechargeable battery. Battery is charged by supplied charger (below). If you open the door while the camera is still writing to the CF card a high pitch beep will continue until the write process has been completed, otherwise opening the door powers the camera off.

Those who are very observant may have noticed a small channel running from the battery compartment to the right side of the camera, this is for the optional AC adapter. The cable from a dummy battery runs along this channel and out of the side of the camera through a small spring loaded door.

Battery Charger

The NB-2L Lithium-Ion battery comes with a dedicated battery charger the CB-2LT(E) which has a rated input of 100 - 240 V AC. There's a large light on the front which glows red during charging and turns green at the end of a charge. It takes approximately 80 minutes to fully charge the battery pack.
