Pick by the field of view you actually need: the Sigma 14mm f/1.4 DG DN Art (L-mount) for wide-angle, the Sigma 150-600mm f/5-6.3 DG DN OS Sports (L-mount) for super-telephoto.
Choose the Sigma 14mm f/1.4 DG DN Art (L-mount) if…
- ✓You want more light and background blur — f/1.4 is faster than f/5, better for low light and subject separation.
- ✓You shoot wide — it starts at 14mm vs 150mm for landscapes, interiors and architecture.
- ✓You prefer a fast, compact single focal length — a 14mm prime over a zoom.
- ✓You value portability — at 795g (1.75 lb) it's lighter than the 2100g (4.63 lb) alternative for travel and all-day carry.
Choose the Sigma 150-600mm f/5-6.3 DG DN OS Sports (L-mount) if…
- ✓You need more reach — it goes to 600mm vs 14mm for distant subjects, wildlife and sport.
- ✓You want one-lens flexibility — a 150-600mm zoom covers what the fixed 14mm can't reframe.
- ✓You shoot handheld or on an unstabilised body — it has optical stabilisation, the other doesn't.
- ✓You like close-focus work — 0.3x magnification vs 0.15x.
