Here here, well said. Having used the X100 since it's release and now using the XPRO1 for a sort time, I have to scratch my head as to what all the noise is about. My X100 worked fairly well from the start, with a few hiccups at first, but now works quite well with the latest firmware updates. The XPRO1, for me, has been just hands down near perfect from the start, including the AF.
Now this may be because my XPRO is brand spanking new, while the experts over at Dpreview where stuck using prototypes in their tests. I hope they get their hands on a latest unit for testing.
I have been shooting in dark bars the last two nights (a consequence of a far too strong love of Ale) and I have been very pleased with the AF performance. Of course you have to know where to focus. The AF assist lamp does not hurt either!
Sorry folks, but so far I couldn't be happier.
