That's been my point, but start by not underestimating someone's budget though, people often want to spend thousands on cameras and hundreds on lenses. A 6d and several really good lenses is cheaper than a 5dIV, but newbies will often convince themselves they need 'the best camera'. I'd rather have a 40d and 17-55 than a 750d and kit lens, the 40d will outperform the newer camera right up till the light disappears, but there's ways round that limitation. My favourite example of this was a bloke who wanted to set up a product photography studio, he bought a d810 and started asking about suitable lenses, he 'couldn't afford' any of the suggestions, and then he wanted to know how to set up his studio, but had literally no budget for lighting. His total budget would have got him everything he needed if he'd bought a £500 camera, but he spent all his money on the best camera he could find and was shocked to discover it wouldn't be any use at all. He refused to hear that his best bet was to return the camera, because he was very happy with his purchase of 'the best', he simply couldn't understand what he'd done wrong.
