The autofocus of the Fujinon 8-16 mm is silent and very fast – so fast that, in fact, it’s difficult to measure the focusing time as it is comparable to the time reaction of the tester. Even in difficult lighting conditions it never exceeds 0.2 of a second and in the majority of other cases it seems to be even shorter.

When it comes to the accuracy, with such wide angles of view and the significant depth of field, connected to them, there are no distinct problems but only in good or typical conditions. When it’s darker or when you work against bright light the lens can set the focus and confirm it even if the shot is completely blurred. Such a situation happened to me several times when I was taking photos of our testing charts; what’s interesting it occurred mainly at the shortest focal length. The performance is rather untypical – with the scene and conditions remaining the same the lens performs perfectly well for 5-10 shots, and then you get such a huge miss…

The photo below shows that the tested lens can have a slight tendency to back focus. Still, even if you work in the minimum focusing distance the depth of field encompasses your photographed object anyway. The sharp middle part of the photo and lack of any back-focus problems during real life sessions suggests it’s a very slight problem which might be caused by field curvature.
