- I recall that someone last fall asked about the difference between the
- 100-300mm lens (the non-L one) and the 75-300mm lens, especially since the
- 75-300mm lens wasn't as expensive than the 100-300mm lens. Someone replied that
- the 100-300mm lens felt a bit sturdier, had an USM motor and had somewhat
- better optics. Now, too many people out there has apparently assumed that since
- the 75-300mm lens isn't quite as good as the 100-300mm lens, it must be bad.
- Quite the contrary, I'd say. Both are good lenses. The 100-300mm lens is
- somewhat sharper and has somewhat less distortion (which is NOT to say that the
- 75-300mm lens isn't sharp or that it has lots of distortion), focuses quieter
- and quicker and feels somewhat more sturdy. For its lower price, the 75-300mm
- lens is a good buy as well, IMHO.
