Canon EF 70-300mm f/4-5.6L IS USM Lens
Key Features
  • EF-Mount Lens/Full-Frame Format
  • Aperture Range: f/4 to f/45
  • Two Ultra-Low Dispersion Elements
  • Super Spectra and Fluorine Coatings
Spanning a flexible range of telephoto focal lengths, the EF 70-300mm f/4-5.6L IS USM is a Canon L-series lens characterized by its relatively compact size and versatility. Two ultra-low dispersion elements are used to greatly reduce color fringing and chromatic aberrations throughout the zoom range for high clarity and color accuracy, and a Super Spectra coating has also been applied to suppress flare and ghosting for improved contrast. Also, a floating elements mechanism is employed to maintain consistent image quality throughout the focusing range for notable sharpness from 3.9' to infinity.

I couldn't attach the lens hood. Does it need to turn harder after aligning the red dots? I am afraid it will break lens. Lens hood model is ET-73B.
Asked by: Anonymous
To attach the lens hood, you align the red dots and rotate the hood clockwise until it locks in place.

This lens has had updates lately, is it suitable for new sensors? How would it behave, for example, with a 5D Mark IV?
Asked by: ANDRES
Incredibly suitable for the sensor and will be a nice, sharp, and more portable alternative to say a 100-400mm.

What is the range on a small sensor camera like the 7d?
Asked by: Anonymous
The 7D is a fast camera, so this lens should be a great addition to your kit. Should be no problem using it, and as stated before, the crop sensor will make it 112-480mm equivalent. 300 doesn't give you huge reach, tho I've got shots at Diamondback games that are pretty good using a 300 on a 7D
