I will not add too much after all the glowing reviews of this digital camera, but I must say it's a real treat to take photos with the 550d associated with the 18-135mm zoom; this lens can cover a lot of situations without changing lenses. (This is ideal for wedding photos ...) When the case a marvel ... Lots of options are available, and the growing ISO 6400 really top ... For my part, I recently did a story for a wedding which ended with a dance in the darkness and lighting effects, and I can assure you that I have great pictures that allowed me to find the The atmosphere of the evening on the photos with the warm colors of the projectors and lasers; everything here by mounting the ISO 3200 on the program mode, and without flash use. Really pleased with this camera and since I have one desire is to have a momment and events to photograph.
