I could write 10 pages of this machine! ... While praise !!! And with all devices that I had, I know what I mean. I will not say what others have already written about the picture quality, workability. So I complete my comments with experience of one year (since July 2013) and I will add a few features not listed. I'm in the building. it involves taking the picture parts with the pan (to make it look right throughout the room in a single picture), photographs the sites, of loins, close up, from the top to the bottom; he has seen into the dark house foundations, amid scorpions !. He spent a week in the mud in the sun (I had lost in the Camargue) he got cold feet (a bull to me snatched from the hands). he lived construction sites in the snow with only refuge -30 pocket of the jacket (with the cold it takes several batteries (I have 4. They are discharged in 15 minutes at very low temperatures) he went in the most unexpected places :( washing machine, paint, cement, plaster, plaster powder, plugged drains to a rope, leakage research in the sewage pipes, downhill rafting, high mountains, waterfalls, underwater, sea diving and lakes, children 5 to 77 years old, cleaners as laundry bleach, soap). I also think visually impaired because it has an incredible fashion magnifier. I was amused to measure. 1 mm becomes 32 mm on the screen. So great to read labels, packaging, material safety data sheets on the devices. Small precision: iso exceeds 12000 in smart mode (and not 3200 as stated on the site) he sees better than me in the dark. (Yes! ... Real) I have since July 2013 and is still there !!!. Nickel works like new. What more?
