I took the X30 as my main camera to the Richmond Folk Festival last weekend. I used it under a variety of conditions, night, rain, indoors, and under cloudy skies. We didn't have much sun last weekend.
This is my first Fuji camera and I realized at one point that I can't process the raw files with my version of Lightroom, but that is okay because I really like the JPEGs it produces. I love the look of the classic chrome preset and the black and white with red filter preset as well.
I used a lot of film simulation bracketing to shoot those two presets. I switched the third film required at various points, but I wish it was possible to only bracket two film types instead of three.
Image quality is pretty good. If you are a pixel-peeper you should probably avoid this camera. At 100% it gets kind of nasty, but at normal viewing sizes the files look very nice. I expected this and it is not a big deal for me.
Autofocus was generally quick enough though it did occasionally miss. I used face detection most of the time and it was pretty reliable at showing a box around the face it found.
The EVF is very clear and nice. This is the first EVF I have ever used and I generally preferred using it instead of the LCD. But the articulated LCD was quite useful in certain situations such as shooting over crowds in front of me.
The camera is capable of shooting 12 FPS and I used that to shoot a breakdancing competition.
I also used the video mode and found it satisfactory for my purposes.
The noise at 3200 was definitely noticeable but I liked the look with black and white, but not so much in color.
Battery life was great and I never had any concerns about running out of power, even during the 12-hour long Saturday.
I did have a few memory card reading errors, which is concerning because I bought a brand new card to use with the camera. There was one occasion that the camera locked up completely and was totally unresponsive. I had to pull the battery to get things working again.
I uploaded a bunch of pics onto Flickr if you want a look.
