Sigma's mirrorless-native 100-400mm Contemporary — compact super-telephoto for Sony FE and L-Mount.
The Sigma 100-400mm f/5-6.3 DG DN OS Contemporary launched in 2020 as a mirrorless-native redesign of the DSLR 100-400mm, available for Sony FE and L-Mount. The DN designation indicates native mirrorless design — lighter and faster AF than adapted DSLR versions.
Optically good — sharp throughout with OS stabilisation. The mirrorless-native design enables faster AF than the DSLR version. Stepping motor for quiet, precise tracking. The Contemporary line prioritises portability — much lighter than Sports alternatives.
Available for Sony FE and L-Mount. 67mm filter thread — remarkably compact for 100-400mm. Approximately 1135g. Dust and splash resistant. OS stabilisation. Arca-Swiss compatible tripod foot. USB-C dock compatible. Minimum focus distance 112cm.
Available used at mid-range prices. The 67mm filter thread at 100-400mm is impressively compact. The Sony 100-400mm f/4.5-5.6 GM OSS is sharper but more expensive. For mirrorless wildlife and sports photographers wanting compact super-telephoto at competitive pricing.
