Test: Einzeltest: Canon EF 400mm f/2.8 L IS USM review
Zitat: If you have a professional need for a beast of this nature, or a bank balance and a back that can stand the hammering, you will not be disappointed. At f/2.8, it is a fast lens for its length and works ideally indoors under lights at such events as fashion shoots as well as on the touchline or a fast bend. It also combines well with Canon’s teleconverter range, still giving autofocus with the 2x. But be warned, this is the heaviest lens Canon produce! In summary, the positive points of the Canon 400mm f/2.8 L IS USM are: Excellent optical performance Good focus pre-set and Image stabilisation Very solid build quality The negative points are: Weight Price IS modes and the switch to change them.
