Read the passage below and answer the question or follow the instruction: Can you summarize the features and benefits of the D-Rebel XSi camera that is currently on promotion by Canon for the Christmas season?

Passage: Canon are offering a fantastic deal just in time for the Christmas season – the D-Rebel XSi Camera is available for just $621 after instant rebates. The camera features a 12.2 megapixel CMOS sensor, and a 3-inch LCD screen. It also offers some advanced autofocusing features, such as a contrast-detection AF mode, which allows the camera to autofocus without interrupting the preview on the screen – something which was not possible with the first generation of live view DSLRs.
You can fine-tune all of the settings just as you’d expect from a camera of this class. Browsing the pictures is as pleasant as shooting them, with the control dial providing an intuitive way to navigate your collection – and looking them on the huge 3″ screen adds up to the pleasure even more.
To make use of the promotion, just get the camera with the 18-55mm EF-S IS ($566) and 55-250mm EF-S IS ($255) – this normally totals to $821 – however, with the rebate active until mid-January next year, the price is reduced by $200, making it $621 – not a bad deal for such high-grade equipment.
