Panasonic LUMIX S 24-105mm f/4 MACRO O.I.S. vs Sigma 28-45mm f/1.8 DG DN Art (L-mount)
The bottom line
Similar coverage, different speed: the Sigma 28-45mm f/1.8 DG DN Art (L-mount) opens to f/1.8 versus the Panasonic LUMIX S 24-105mm f/4 MACRO O.I.S.'s f/4 — more light and shallower background blur. The Panasonic LUMIX S 24-105mm f/4 MACRO O.I.S. gives that up to stay lighter (680g (1.50 lb)). It comes down to how much you value that extra brightness.
Choose the Panasonic LUMIX S 24-105mm f/4 MACRO O.I.S. if…
- ✓You need more reach — it goes to 105mm vs 45mm for distant subjects, wildlife and sport.
- ✓You shoot handheld or on an unstabilised body — it has optical stabilisation, the other doesn't.
- ✓You value portability — at 680g (1.50 lb) it's lighter than the 1020g (2.25 lb) alternative for travel and all-day carry.
- ✓You like close-focus work — 0.5x magnification vs 0.26x.
Choose the Sigma 28-45mm f/1.8 DG DN Art (L-mount) if…
- ✓You want more light and background blur — f/1.8 is faster than f/4, better for low light and subject separation.
