Looks like the same awful af system an terrible laggy fly by wire focus ring, the sensor might be nice but if you can't focus it's not too much use.
I suppose if you count classifying it as the same type "contrast detect" as the x100 and a few hundred other cameras out there..
As a x100 user I tend to agree the AF needs to be suitable for more types of photography than is the x100. The x100's autofocus isn't "terrible", it's outstanding for certain types of photography, okay for other types, and mehhh for others.
Perceptions are funny. I loaned my x100 to a friend who took it to China for 4-5 weeks and he constantly complained about the AF. I didn't think it was that bad, but I had just did that major firmware update before I sent it out without testing it, so I was eager to get it back to see if maybe the firmware update had some detrimental effect. Most of his images weren't OOF.. but they were soft. Once I had it back I used it for 2-3 outings and my images were sharp.. same sort of shooting, same type of subjects. There is an obvious discrepancy between our images. This guy isn't an inexperienced photographer either, but I do believe if I was standing next to him I'd be able to pick out why he was getting soft images with the same type of shots I was getting sharp images from. It's a huge guess, but I'd guess this is probably true for the 50% of users who are okay with the x100's AF and the 50% who aren't.
And obviously it's not suitable for several types of photography..
Before I had the x100 I had the NEX-5 and 10+ other PNS cameras.. and I felt there was a void. The x100 filled about 90% of that void. Everyone's void (needs) is different. The XPro1 is an exciting camera, but I no longer have that void to fill.. or as much of it. So I can afford to sit back and wait for the reviews and user reports to come in. If the XPro1 fills the void 98-100% then I'll look at the price, the functions the x100 doesn't have, and make a decision.
What I don't expect it to do, is to replace my DSLR's. I use these professionally and they need to be suitable for a wide variety of photographic needs. I don't expect the XPro1 to be that capable. I doubt any camera of this type will be that capable. This means the XPro1 fills the void for personal use. And frankly the x100 does a really good job of that.. it fills that void 90%.
Yet, I really like the XPro1 concept and I'm sure most x100 owners do as well. Fuji has to know that we'll be watching to see 'how much' better the XPro1 is than the x100. Interchangeable lenses alone won't cut it. It will need to be a complete camera with no major issues. At this price point autofocus will need to be one of the best out there on cameras of this type. Manual focus as well. Fuji knows this, and they know the XPro1 will most likely be a failure if they don't correct the issue. I would hope they're not that blind.
