Sad news for me, last night I dropped my 1.5 years old F30 and now it doesnt work anymore (cannot turn on to take photos, can only playback). So it looks like its time to shop for another super PnS, I'm a bit disappointed to read the reviews of the F50 thus far.
From the sample photos of the F50 here, I notice similar lines / banding problem that plagued the F11 (and some F10s). I used to own an F11 and the banding drove me nuts. I went to Fuji service center so many times but they couldnt do anything about it, even swapping to a new camera was no use. Glad they fixed it in the F30/F31, but looks like it may be back again with the F50. But there's no other option out there for a small camera with good high ISO performance now, sigh... how how?
Edit: After looking at more ISO1600 photos, it looks like the banding isnt as bad as it was on the F10/F11... plus that SD card slot looks tempting... now if only they'd have a version with 28mm wide angle.
Edit: I went ahead and just bought the F50 anyway. Took some handheld night shots along Boat Quay, mostly at ISO800. Not too bad lah, the lower CA compared to F30 is a nice improvement. Another plus point is that the F50 is noticeably slimmer than the F30.
