The 55-200mm DC fills the entry telephoto role for APS-C systems: at 82.5-300mm equivalent it covers the practical telephoto range from short portrait compression to 300mm equivalent telephoto for distant subjects. The 1.1m MFD is longer than typical telephoto zooms, limiting use for close approach. The lightweight 310g body pairs well with entry-level APS-C bodies.
On the used market the Sigma 55-200mm f/4-5.6 DC is very affordable as a vintage APS-C telephoto zoom. Condition checks: zoom ring smoothness, 55mm front element for marks, and aperture blade operation. DC designation — APS-C only.
