The Canon IXUS AF and IXUS FF are low-end parts of the IXUS APS film range, introduced by Canon in March 1999. Compared to other IXUS's, they are quite basic; the body is entirely plastic, and the cameras lack some of the advanced APS features of other models. The differences between the two are that the AF has autofocus and is metallic blue, and the FF is fixed-focus and is silver - although both have a black back. There were two models: date-enabled and without-date.

The body is very compact, although quite deep as the lens does not retract far, at 98 (including wrist strap loop) x 65 x 35mm {~3.86x2.56x1.38 inches} (with-date model; without date model is 30mm deep[1]).

The fixed-length 3-element 25mm f/6 lens is mechanically extended by the sliding on-off switch - and retracted and covered when switched off. There is a small LCD settings panel in the top, along with self-timer and flash mode buttons. The CdS-cell exposure automation controls the shutter, with speeds of 1/500 (for EV13.7 or greater), 1/250 (EV12.7-13.7) or 1/90 (EV12.7 or less).

The back is featureless apart from the viewfinder eyepiece, a green "OK to Shoot" LED and the APS format switch.

Power comes from a 3v CR2 battery, inserted into the left end.

The AF & FF were only marketed in Europe, and so there are no equivalent US Elph or Japanese IXY named versions.
