Originally posted by Don From The Radio Some people use long lenses for landscapes to avoid the distortion, but that also opens a whole new can of worms. In the end, what works for you personally is best. In your shoes, I'd go through my photos of the type that you want to take, see what focal lengths you use most, then get a prime near that length.
Most of my pictures are taken between 18 and 30, but I find that I lack a bit of angle for some interior shots, and some landscapes as well.
That's why I was thinking about a slightly wider and supposedly sharper lens, such as the 16-45.
On the other hand a 10-20 would allow me to create really different compositions.
