The function button brings up a quick menu which allows adjustment of most common shooting options including metering mode, autofocus options, flash modes and the Creative Styles tone adjustment feature, but also duplicates the function of several of the buttons, such as ISO setting and drive mode. The main menu holds a similarly limited number of options, with only basics such as image size and quality (including Raw and Raw + JPEG), image stabiliser (on or off), a choice of Adobe RGB or sRGB colour space and a few more basic options, including image aspect ratio. The main section of the menu is only just over one page, and exhibits considerably less customisation than most other mid-level DSLRs.
One good point is the viewfinder, which has a nice wide screen with the nine AF points clearly marked with red LEDs, and a decent data display along the bottom. It has a 95 percent field of view and 0.83x magnification, with dioptric correction for spectacle wearers. There are two proximity sensors just above the viewfinder for the Eye-start AF feature, which focuses the camera as soon as it is held up to the eye.
The overwhelming impression of the A450 is that Sony has taken the much better A550, which sells for around £600, and stripped out a number of features to get the camera on sale below a certain price point. As a result the camera always feels as though it is lacking something, and that it could have been much better if only a little more money had been spent. This is indeed true, because then it would have been an A550.
