I bough this zoom as a smaller alternative to the Canon 25-105 F3.5. While it's quality is not as good as the Canon's it is pretty close. It is a very compact lens and has a very impressive macro capability - much better than most zooms of this era. Since i bought it in 1984 and it still works fine today the build must be solid. Even the lens hood is a quality item although it is inconvenient to fit.
