Tamron 150-500mm F/5-6.7 Di III VC VXD vs Viltrox AF 75mm f/1.2 Pro FE
The bottom line
These cover different focal lengths — the Tamron 150-500mm F/5-6.7 Di III VC VXD is 150-500mm, the Viltrox AF 75mm f/1.2 Pro FE is 75mm — so they're not really substitutes. Pick by the field of view you actually need: the Tamron 150-500mm F/5-6.7 Di III VC VXD for super-telephoto, the Viltrox AF 75mm f/1.2 Pro FE for short-telephoto / portrait.
Choose the Tamron 150-500mm F/5-6.7 Di III VC VXD if…
- ✓You need more reach — it goes to 500mm vs 75mm for distant subjects, wildlife and sport.
- ✓You want one-lens flexibility — a 150-500mm zoom covers what the fixed 75mm can't reframe.
- ✓You shoot handheld or on an unstabilised body — it has optical stabilisation, the other doesn't.
- ✓You like close-focus work — 0.33x magnification vs 0.12x.
Choose the Viltrox AF 75mm f/1.2 Pro FE if…
- ✓You want more light and background blur — f/1.2 is faster than f/5, better for low light and subject separation.
- ✓You shoot wide — it starts at 75mm vs 150mm for landscapes, interiors and architecture.
- ✓You prefer a fast, compact single focal length — a 75mm prime over a zoom.
- ✓You value portability — at 665g (1.47 lb) it's lighter than the 1725g (3.80 lb) alternative for travel and all-day carry.
