Improvements:
The best optical wide angle and ending 1200mm (35mm equivalent).
The wifi to transfer photos on his tablet.
The general ergonomics redesigned and more intuitive.
Assistance in manual focus that I use frequently (in addition to auto focus).
Video and stabilization seems improved compared to you it HX100.
My disappointments:
The tiny increasingly inflated pixel sensor that delivers pictures at fault bruitées..La marketers who think that buyers see only by the number of megapixels. Stop!
Burst mode which "freezes" literally a bridge for at least 10 seconds, the time of writing on the SD card. Incomprehensible not to have expected another burst mode (10 or 2 frames / s) but keeps your subject photographed in the viewfinder while the Class 10 SD cards are ultra efficient. If you like wildlife photography, you'll cry .... the others as well!
Some annoying details like the Deleting a picture (yes one!) And that sometimes takes 4S (regression / the HX100).
The transfer wifi limited to 100 photos if you select them one by one (you must then renew).
The wireless application dedicated to smartphones that informs evil of the transfer progress of your photos with a fake countdown countdown. You think you have uploaded all your photos on your tablet: error. Expect a good message end otherwise it will start again.
Conclusion: I still recommend because competitors are sometimes criticized but still little improvement.
