Have tested this camera for some days. It´s a big disappointment. Pics are lacking details and aren´t crisp. Same thing regardless if JPEG or RAW. Noise performance is a shame for Nikon. Controls are frustrating as there are not enough buttons, e.g. there is no ISO button, you have to change ISO in the awkward menu.
The 1 system is a joke, the price-tag just outrageous. You can get a decent DSLR for this price, a good mirrorless cam from other brands or a high-end-compact if you want small size - will perform ways better than the J3.
Another joke is the mentioning of aluminium body on Nikons site. Only the front element is made of aluminium, the rest is plastic and the top plate produces cracking noises when touching it.
I don´t recomment the J3 at all.
