Isit true..Normally body cheap will need expensive lenses and expensive body does well with cheap lenses
Not necessarily, I personally find that canon rebels perform better with the cheaper ef-s lenses versus the ef L lenses. On the other hand, while you can pull more than decent images from a expensive camera and cheap lens combination, why not spend a little more and get more of what you paid for for the camera body?
In regard to sony, I've only used their a6000 and 6300, which I find works well with either cheap or expensive lenses (the expensive lenses make the setup too unbalanced and unwieldy though). I still like the cheap ones more, can throw around abit and if break at least it doesn't cost an arm and a leg to replace.
Haven't tried fuji, but I do agree that for the price, you might as well go all in and get some nice lenses to go with the camera...
