Half a kilogram with 450mm on the end of it is the trade this lens makes, and it's why it's our top pick. The XF70-300mm weighs 580 g and reaches 450mm in full-frame terms, so it drops into the same bag as a standard zoom without a second thought. On a small X-mount body it sits forward of your hand rather than dragging it down — a different experience from the long lenses further down this list.
Fujifilm builds it from 17 elements in 12 groups, including one aspherical and two ED elements, and seals the barrel at 10 points against dust, splash and cold. The sealing is the specification we kept coming back to. A long lens is the one you carry when the forecast turns, and this is the least expensive sealed lens in this group, which makes the value argument a short one. Stabilization is on board as well, and it's what lets you keep shooting handheld at the long end instead of hunting for a fence post to lean on.
Where it stops is at the far end. If your subjects are reliably small and far away — waders on a mudflat, a receiver at the back of the end zone — the 100-400mm and the 150-600mm buy you real distance, and no amount of cropping closes that gap cleanly. For everything short of that, we think the smaller lens is the one that actually leaves the house, and that's worth more than the last 150mm.
Pros
- 450mm equivalent reach at 580 g
- Sealed against dust, splash and low temperatures
- The least expensive sealed lens in this set
Cons
- f/4-5.6 aperture is slow in dim light
Our default pick: 450mm of full-frame-equivalent reach in a weather-sealed 580 g barrel, for less than any other sealed lens here.
