T3i 3x Crop Zoom Demonstration

Posted on 6/14/2011 1:41:00 AM

With the 3X crop zoom, it gives Canon T3i additional power on filming with a standard zoom lens.

To allow better zoom range, we carry a standard zoom lens, and the Canon 70-200mm F2.8L lens when shooting wedding. Not only the 70-200mm L-lens is bit heavy and bulky, it's inconvenience and not easy to switch lens during wedding shoot. With T3i's crop zoom, it gives 3 times zoom range from the standard lens.
Below is the screen capture from the Canon 17-55mm F2.8 Lens on T3i.

With the 3x zoom factor, it turns the 17-55mm standard zoom lens into a 17-165mm standard-telephoto zoom lens (neglecting the 1.6 APS-C crop factor).
