The Canon PowerShot G3 is by many regarded as the most successful camera in the Canon G-range, although the 4 mega pixels image sensor is somewhat less than optimal compared to cameras having about twice that amount. The important features this camera offers, however, are the fast lens with a particularly good close-up range, an optical viewfinder for eyelevel photographing, and most importantly the capability to deliver natural colored images of high quality and with realistic human skin hues. A very useful LCD screen, which can be twisted and turned for viewing from almost any direction, is very convenient, especially for on the ground macro photography, and for above the crowd over the head shooting. The image on the screen is always the right way up, regardless of how the screen is rotated, and the camera includes horizontal/vertical format information in the picture file.
The provision for live "remote capture" photography, using the USB cable for connection to a personal computer, is particularly valuable for studio work, providing full control using the computer for the camera settings and on-screen image preview. The files can be directly downloaded for further processing, and be instantly evaluated using the photographer's image-editing program on the computer.
The separately available lens adapter, LA-DC58B, that replaces the standard lens barrel collar, provides an extremely useful 58mm filter thread for lens attachments, enabling the use of normal filters, close-up lenses, and the separately available wide-angle and tele-converters, or any other useful attachment like a slide/negative-adapter for digitalizing any size of film format.
The camera is supplied with a useful set of programs on a CD, the required cables, and a small handheld remote control, but perhaps more importantly, a high capacity rechargeable BP-511 battery, and a battery-in-camera mains operated charger, which also powers the camera directly from the mains, making the camera independent of battery power for studio work. The camera takes the CompactFlash type 1 memory card.
