Sony FE 50-150mm f/2 GM vs Sony FE 50mm f/2.5 G

The Sony FE 50-150mm f/2 GM is a zoom (50-150mm) and the Sony FE 50mm f/2.5 G is a 50mm prime. The zoom gives you framing flexibility from one lens; the prime trades that for a fixed focal length that's usually brighter and lighter to carry. Choose flexibility or a fast single focal length.

Choose the Sony FE 50-150mm f/2 GM if you want more light and background blur — f/2 is faster than f/2.5, better for low light and subject separation. Choose it if you need more reach — it goes to 150mm vs 50mm for distant subjects, wildlife and sport. Choose it if you want one-lens flexibility — a 50-150mm zoom covers what the fixed 50mm can't reframe. Choose it if you use filters or shoot video — internal zoom keeps length and balance constant.

Choose the Sony FE 50mm f/2.5 G if you're on a budget — $599 vs $3,899 leaves more for other gear. Choose it if you prefer a fast, compact single focal length — a 50mm prime over a zoom. Choose it if you value portability — at 174g (6.1 oz) it's lighter than the 1340g (2.95 lb) alternative for travel and all-day carry.

Aperture: the Sony FE 50-150mm f/2 GM opens to f/2 vs the Sony FE 50mm f/2.5 G's f/2.5 — more light and shallower depth-of-field.
