It may be damaged from the drop so take it for a repair to you nearest camera repairer. Check out the cost before as it may not be worth repairing and a replacement would be in order

Replace the broken ribbon cable in the lens

Probably needs a new ribbon cable in the lens. This flexible cable maintains the contact as the lens is zoomed in and out. If it is still under warranty take it back to B&H for a simple repair.

Yes, it's suitable for 35mm EOS mount Canons and all digital models. If the digital SLR has an APS-C sensor then the image will be cropped and will give the same viewing angles as a 112-480mm on a 35mm camera.

Sounds like your imaging sensor has failed and is not recording blue or green tones. Take your camera to a good camera store or send it to Canon for a service estimate.

Same as any camera - uncover lens, point camera at subject, press shutter button. Simples.

I think it is due to the extensive choice of quality lenses.

Contact Canon directly to inquire.

The camera is trying to process information to or from the memory card. If the status does not change after a few minutes, you may have a damaged memory card. Turn the camera off. Remove the memory card and inspect it. Reinsert the memory card. Can you view photos on the LCD by pressing the arrow button? If so reconnect to your computer. If not, you most likely have a damaged memory card. Try inserting the memory card into a card reader connected directly to your computer. This may be able to still read the card when your camera cannot.
