Better AF with x-pro 2 on older lenses?

[petergabriel]

I have the 23 and 35mm f1.4 as well as the 14mm f2.8. Will any of these lenses benfit from the improved AF or will only the newer WR lenses do that? Coming from x-pro 1. Can't decide whether to upgrade. Would love fewer missed shots though.

Yes in my OPINION you'll notice a tangible difference with those lenses,

 

I've owned the same 35 f1.4 across 4 X bodies (xe1, xp1 xt1 & xp2) and it definitely performs better on the newer bodies

 

The difference between the xt1 & the xp2 isn't so much, but between the first generation bodies it's there

 

There is a massive caveat though

 

Firstly, the difference between a fast AF lens and a not so fast one is fractions of a second, sure as a percentage it's a lot, but irl not so much

 

Secondly, many factors affect AF... subject, what's in the background, light etc

 

To simply state something like 'buy the latest Fuji and you'll never struggle with AF ever again' would just be plain wrong

I am not so much interested in speedier AF, as I think the x-pro 1 does a pretty decent job when the conditions are right, I am more interested in improved low light performance, better back light performance and less hunting (pdaf) which off course all amounts to faster AF, but more importantly, increased accuracy.
