The key differences between the Nikon 55-300mm and 70-300mm lenses are their focal lengths and maximum apertures. The 55-300mm lens has a slightly shorter focal length range and a smaller maximum aperture compared to the 70-300mm lens.
If you are looking for a lens with a longer reach and better low-light performance, the 70-300mm lens would be more suitable for your Photography needs. However, if you prioritize a lighter and more compact lens, the 55-300mm lens may be a better option for you. Ultimately, the choice between the two lenses depends on your specific photography preferences and shooting conditions.
