- Is f/1.8 worth it over an f/2.8 standard zoom?
- Yes if you shoot in low light or want shallow depth of field without switching to primes. An f/2.8 zoom is smaller and lighter but gives up more than a stop of light.
- What is the full-frame equivalent focal range?
- On APS-C it behaves like roughly 26-60mm on full frame, covering wide angle to short portrait telephoto.
- Does it work on full-frame Sony bodies?
- It is a DC (APS-C) lens. On a full-frame E-mount body it will crop to APS-C mode, so you lose resolution outside the crop.
- Does it have image stabilization?
- No. It relies on the camera's in-body stabilization, which most recent Sony, L-Mount and Fujifilm bodies have.
- What comes in the box?
- The lens and a petal-shaped lens hood. Front and rear caps are standard; the 67mm filter thread takes screw-in filters.
- How close can it focus?
- 28 cm at the long end, with 1:4.8 maximum magnification, which is useful for close-up detail shots.
