why the fascination with "fast" AF, or are we all sheep?
the fuji X systems are not DSLR's and not made to function as one, nor are M43rd systems....the quicker we understand this, truly, the more we will enjoy photography as an art.
AF accuracy, not speed, is more of an issue for me personally. To be honest, I don't consider Fuji's AF that "slow" in an of itself (they feel no worse than a 5D mkii, for example), but its inaccuracy also contributes to that feeling of slowness at times. Real, mechanically-linked RF mechanisms are slower still but because of the feedback from the RF patch, they are more accurate. And those who are used to the accuracy of a nice RF would agree with me that one properly focused photo shot with an RF is still faster than two shots taken with an AF system because the AF bungled the first shot by focusing on the background instead of the subject. Many here who are accustomed to using "real" RF systems would find the delays/slowdowns resulting from having to refocus via AF annoying because they're used to extremely short "lock" times on their RF cameras, and direct, instant focus feedback.
Despite these issues, I LOVE my Fujis and have been on board with the X system since a month after the X100 hit the market. They aren't perfect, and we wish they did some things better than others. But when is that not the case? M240 owners probably wish they had the X Pro's high ISO capabilities. 1D X owners wish their cameras didn't weigh so damn much. And film camera M owners probably all secretly wish they had rear doors that swung out when it's time to load a fresh roll (HERESY! but come on be honest with yourself).
I agree with jsrockit; just because it isn't a DSLR doesn't stop us from wishing the Fuji Xes were a little faster in the focusing dept. But to use your art analogy, while we're all happy with our existing tools, some of us wish those tools were just a little sharper. I think the quest for better tools has been around since the first primitive human drew an ancient graffiti dong on humanity's first cave-bathroom wall with a piece of charcoal (and you totally know that happened, yo).
The grass could always be a little greener on the side of the field you're standing in is what I'm sayin. And that doesn't have much to do with "art".
