I am looking for a good camera for private investigative work. I would be happy with a used camera so recommending an older model is fine. I need really good low light shots from about 100 ft (so good camera plus lens options) and the ability to take long distance daytime shots. I've seen great cameras but they are way too expensive which is why I am wondering what older models people would suggest. Maybe a body I can get under $500 and then lenses would be good. I am just starting out so I need something super functional (at least 12 MP still and 720P video) so I can make money a save up for the newest high end camera. Thanks for the help.
