I've said it before on these forums but for such an expensive camera it is reasonable for a customer to expect the performance to match its peers. Image quality is generally great but performance is certainly not the strongest area. Is it a show stopper? Of course not. Should it be better with such a recent camera? In my opinion yes. Who out there wouldn't rush to download the latest firmware if Fuji announced it would match the performance of the best in its class? Don't get me wrong - it's a great camera but the focus performance and lag can be a real pain at times and quite rightly these weaknesses are regularly referenced in professional and user reviews.
