Overview of Fujifilm GF 250mm f/4 R WR
For a general understanding of format equivalence, see Format-Equivalent Depth of Field and F-Stop.
The about $3299 Fujifilm GF 250mm f/4 R LM OIS WR (discounted to ~$2520) is equivalent to a 205mm f/3.3 lens as compared to a 35mm full frame camera (long dimension of frame). It is thus a long telephoto lens with commensurate challenges for depth of field.
