This model is way past its prime and has since been replaced. It most closely resembles the new Canon Powershot SD1400 IS. Here's what we had to say about the SD890 when it was released in March 2008.
Canon just keeps making new cameras. The SD890 IS is a bump up, marrying a 10-megapixel sensor with lens-shift image stabilization, making this tiny ultracompact a very appealing package. Additionally, the SD890 IS features a 5x optical zoom lens, perhaps the largest lens available in an ultracompact style model. If you're looking for highly-detailed photographs and the confidence and reliability of a great brand, the Canon SD890 IS is a sure winner.
