The camera is a little over two years old, has seen everything, and rain and snow and sand and frost -35. In the cold, the battery lasts much less like all the others. But if you use it as you took it, took a dozen pictures and removed it for a week, then the battery will last for 3 months. The quality of the picture is quite acceptable. You can shoot in JPEG, RAW and JPEG and RAW together. I took it for 24k with a Kitovskiy 18-55 lens. I did not regret the purchase. I immediately saw the difference after a soap dish for 10k with the naked eye. When buying, see the manufacturer. There are two options - Thailand and Toli Malaysia, Toli Japan, in general, they say the second option is better, although what ?, remains a mystery.
