What are the main differences between a 55-300mm lens and a 70-300mm lens in terms of focal length and performance?

The main difference between a 55-300mm lens and a 70-300mm lens is the range of focal lengths they offer. The 55-300mm lens has a slightly shorter focal length range, while the 70-300mm lens provides a longer reach. In terms of performance, the 70-300mm lens may offer better image quality and sharper results at the longer end of the focal length range compared to the 55-300mm lens.
