Yes. Why shouldn't I? Presumably Fuji has carefully tested the lenses in a controlled situation. Also, the numbers seem in-line with my lenses (14/23/35/60) and from what I've read online. Does something look odd to you?
Nothing looks odd to me. But I tend to view brand-sponsored data on things like speed, performance, and precision with a grain of salt. They do, after all, have an agenda-- selling more stuff.
The other thing is that I assume those tests are under optimal, controlled settings. I don't doubt the chart accurately reflects the optimal findings from the actual tests conducted.
But I do think we get more variables into the mix, and a closer approximation of real-world results... when we get outside opinions (from actual shooters) from real-world use.
Comparing the chart to some of the responses, I wonder if the variability we're seeing in the 18-55 performance is because some people are shooting that lends in PDAF mode, while others don't have cameras that support the feature. Some people are putting that lens in the fastest end of the spectrum, and some are putting it on the slowest end. Interesting.
