Fit and finish looks good, certainly seems as good as the HS10, and yes like the HS10 the battery cover does wriggle around slightly when in use but its not likely to cause a problem. The lens barrel on extending the lens did exhibit a very tiny, and I mean tiny rough point at the mid transition point of the lens. This has now smoothed out and is no longer noticeable. The lens zoom is slightly tighter than my HS10 was but it is still very smooth.
The EVF diopter wheel was easier to adjust and I think Fuji may have slightly changed the outer casing to allow for this, certainly it was much easier to use than the HS10's. Another nice touch is the addition on a thumb grip pad for extra control, its a simple thing but a feature I like.
It certainly seems that having the camera produced in China hasn't detracted from the finished product, in my case at least.
After taking a couple of hundred photos in quick succession over a period of an hour and switching constantly between modes I got the heat warning indicator show up. At this point I had been using the supplied alkaline battery's (Panasonics) and they had become mildly warm. Not unexpected from this type of battery but nothing to worry about. I eased the LCD out and put my finger directly on the back of the casing of the camera. A small amount of warmth could be felt at this time. Ambient air temperature was about 18 degrees Celsius, so in a really hot climate the camera after a period of intense use could possibly get warmer than one may like. I found that easing the LCD out of its bay by 4 or 5mm was sufficient to help with cooling and the temperate warning didn't come on again. At this point I haven't updated the firmware as I want to push the camera a little harder yet. Up to now I haven't seen any sign of image degradation from the camera with the warning showing and I continued to shoot another 50 odd shots before turning the camera off.
Heres a link to some of the shots I took the first day out. They have been PP'd a little but not drastically so.
All in all Fit & finish is good and exactly what I would expect from a new camera.
