10. Autofocus

When the Fujinon 2/50 is attached to the X-T2 its autofocus is fast, efficient and noiseless. Running through the whole distance scale and confirming the focus takes about 0.4-0.5 of a second, no matter the direction of the movement or lighting conditions.

With the older body the situation changes. When the lens cooperates with the X-E1 the focusing might even take as long as 0.8-0.9 of a second even if with the newest camera software installed.

When it comes to the accuracy on the X-E1 it didn’t bowl us over. Even in studio conditions we had to take into account a number of misses reaching 7-8%. The situation was better in the case of the X-T2 which neither in the studio (2% of misses) nor in outdoor conditions gave us any serious reasons to complain.

Still it’s worth noticing that our test was performed already after the announcement of new software for the X-T2 which is supposed to improve the autofocus work among other things and is going to be available on the market in May this year at the latest.

In the case of both bodies used in our test we noticed a slight front focus tendency. Still that problem wasn’t especially pronounced because the depth seemed to cover the photographed object anyway and the effect was visible only while taking a photo from closer distances. It’s possible it was caused partially by the field curvature.
