Canon PowerShot A640

Model Design / Appearance (6.75)
A look at the A-series lineup shows just how much Canon has tweaked design in the past few years: not much at all. The Canon PowerShot A-series digital cameras have a certain utilitarian aesthetic to them. They all have chunky hand grips, telescoping lenses, optical viewfinders, and thick bodies. Most have folding LCD monitors and similar button and dial layouts. The Canon PowerShot A640 follows these traditional A-series guidelines, but it differs in its body color. Most A-series models – but not all – only come in the typical light silver color. The A640 has a black body that is comprised of plastic and metal panels. There are a few light silver highlights: the lens rim, shutter release button, mode dial, navigational control, etc. The overall appearance of the Canon A640 doesn’t scream “gorgeous,” though consumers after something more stylish and trendy will likely gravitate towards Canon's SD-series; however, the SD-series doesn’t come with the same vast amount of manual controls.

Size / Portability (5.5)
The Canon PowerShot A640 isn’t a waif of a digital camera. It measures 4.31 x 2.6 x 1.93 inches. It has boxy dimensions, but its edges are rounded and the panels match well together. It weighs in at 8.64 oz (245 g), but that’s without the four AA batteries included. The A640 is much too chunky to slide into a pants pocket comfortably, but it can still be transported in a large coat pocket or hand bag. It doesn’t require a separate camera bag, although that never hurts (especially if you invest in the conversion lenses, slave flash, and other accessories). The A640 has a strap eyelet to attach an included wrist band, but this camera is too heavy to dangle from a wrist. Even if your wrists are incredibly strong, I still wouldn’t trust the flimsy wrist strap.

Handling Ability (7.0)
While consumers may curse the A640 for not being as skinny and portable as other digital cameras, they should forgive it when they handle it. The chunky hand grip keeps your palm from cramping permanently, and the placement of the controls and buttons are all within easy reach. There are a few potential problems, however, the metal hand grip material is slick, and the body is quite heavy. The hand grip shouldn’t be a big problem unless the photographer’s palms are sweating profusely or a coating of sun block was just slathered on. As for the weight of the camera, there’s really no way to change it. Users should make sure they have two hands on the A640 at all times, though.

Control Button / Dial Positioning / Size (7.0)
As previously stated, all of the A640’s buttons are nicely placed within easy reach. The zoom ring that surrounds the shutter release button is large, as is the enormous mode dial behind these features. The power switch on the back of the camera is a bit on the small side. The four circular buttons that surround the navigational control are nicely sized and spaced. Everything is properly labeled, although at first glance, the back of the camera looks cluttered because of all the buttons and labels. The navigational control consists of a central Func./Set button with a ring around it. The ring has four dots indicating the directions. When users push on a side, it doesn’t depress as much as one would expect. Still, it did its job and didn’t accidentally navigate to other menus.

Menu (7.0)
This PowerShot has a menu system typical of its relatives. The more frequently used shooting options are located in a menu accessible by the Func./Set button. This menu is loaded with lots of options and a live preview of many of them. The menu is set up so that the items appear on the left edge of the LCD screen, and the options for each item appear to the right along with the live preview.
