Focal Length Range
Telephoto zoom lenses are typically purchased to cover the focal lengths longer than one's general purpose zoom lens and that is the case with the 70-300mm range. Many general purpose zoom lenses feature a 50-55mm max focal length and most will not worry about the small amount of gap in coverage between that lens and this lens' widest focal length, 70mm. While most can overlook a small gap in angle of view coverage, having an overlap in coverage (an 18-135mm range paired with 70-300mm for example) should also not cause concern as this focal length overlap is often very welcomed.
Max Aperture
The f/4-5.6 in the lens name refers to the lens' max aperture opening, the relationship of lens opening to focal length. The lower the number, the more light the lens will allow to reach the sensor, enabling shorter exposures and/or lower, less-noisy ISO settings. Each "stop" in aperture change (examples: f/2.8, f/4.0, f/5.6, f/8, f/11) increases or reduces the amount of light reaching the sensor by a factor of 2x (a big deal).
Image Stabilization
Wide apertures are also advantageous for shooting handheld in low light. While this lens does not have that advantage, it has another sometimes-even-better feature for this purpose. That feature is of course image stabilization (IS). As mentioned, this lens' distant ancestor was the first Canon DSLR lens to have this feature and the technology has come a long way since then.
