I bought an FT25 because I wanted an internal zoom and that this is done only waterproof camera from Panasonic. Compared to my previous FP1, the picture quality is about the same, that is very good although the wide-angle, it may be of interest in interior picture does not seem to play in favor of the new in terms of quality. Unless this is the glut of pixels that tends to affect the quality while weighting clichés. The fact that it is a sealed unit complicates things a lot. While intuitively enough to slide the lens cover on the FP1, we must now look for the startup button. The objective is no longer protected between two uses. The battery door is often reluctant to open because of the sealing gaskets. At each startup, you must press the OK button 2 times to '' jump '' read the warnings about the sealing. Annoying. Furthermore, an SD card already used by a computer could not be used while the FP1 has formatted without problems!
