Sigma's DSLR 100-400mm — same as ID 1119, possible non-OS or mount variant.
The Sigma 100-400mm f/5-6.3 DG appears to be a variant of the Sigma 100-400mm family — possibly lacking OS stabilisation or HSM motor designation compared to the Contemporary version (ID 1119). Check for specific version differences.
Similar specification to the Contemporary version — 100-400mm at variable f/5-6.3 for full-frame DSLRs. The DG designation without OS or HSM may indicate an earlier or budget variant without stabilisation. Verify specification carefully on used copies.
Available for Canon EF, Nikon F, and Sony A mounts with 67mm filter thread if Contemporary version. Approximately 1160g. Check for OS stabilisation — the key practical feature. Full-frame coverage for wildlife and sports photography.
Check against ID 1119 for the Contemporary version with OS and HSM — that version is strongly preferred with stabilisation. Available used at budget to mid-range prices. Verify whether this specific variant includes OS before purchasing.
