What are the key differences between the Canon 70-300 and the Canon 70-200 lenses, and which one would be more suitable for my photography needs?

The key differences between the Canon 70-300 and the Canon 70-200 lenses are their focal lengths and maximum apertures. The Canon 70-300 has a longer focal length range and is more versatile for shooting distant subjects, while the Canon 70-200 has a wider maximum aperture which allows for better low-light performance and more background blur.

If you need more reach and versatility for shooting distant subjects, the Canon 70-300 would be more suitable for your Photography needs. If you prioritize low-light performance and background blur, the Canon 70-200 would be a better choice.
