Remarks:
An 8×20 binocular that isn’t pocketable?? 8×20 has so far been the configuration for pocket binoculars (e.g. Trinovid 8×20), for which the disadvantages of the small 2.5mm exit pupil (only marginally useful when light is scarce) and the difficulty to hold the bino still (despite the muscle tremor) were “compensated” with ultralight weight and tiny dimensions. The Canon, however, is neither ultralight nor tiny. Nevertheless, the initial impression of this smallest Canon IS binocular is positive (see below under “Review”). Further testing will have to reveal its usefulness in the field.
