Hello, I saw a panasonic on display at a large department store here in Colombia for about 150 dollars, with kit lens, but without battery nor charger. I wanted your opinion on if I should or should not buy it. Everything looks ok except that the camera is on display without a lens, just with some plastic and tape over the lens mount. I uncovered it and the sensor has a big fingerprint on it. Given the price, i could still make a very good deal if I bought it and have the sensor cleaned, but i worry about how much the sensor can have been affected because someone put a finger on it... Any advices? Should i risk it or do you think that it can have permanent damage? If you have any experience buying displayed items please share. I was thinking about using it mainly for video interviews. Thanks in advance from Colombia.
