Besides the Canon 8×25 and the new Canon 8×20 (see separate post, https://binocular.ch/canon-8×20-is/) and 10×20 models, the 10×30 IS is the smallest of the image stabilized range of binoculars by Canon. Great image stabilization and very respectable optics for a modest price; the drawbacks are a relatively modest field of view and a binocular body that is neither very sturdy nor water- or dustproof.



A brief comparison with the newer 10×32 IS here:
