The lens matter more than the bodies imo. Think about how you want to shoot. Street photography? Landscape shots? Low light? Nice bokeh?
If you are planning on doing street, nighttime, low light, want bokeh, you'll want a good fast prime.
If you are doing daytime landscape shots the lens being fast won't matter as much but see if the lens system has good wide angle lenses.
Or if you plan on taking a lot of animal shots or need to zoom look at how well the telephoto lenses are, if the aperture ranges are acceptable and how varied the focal lengths are.
I've made my opinions pretty clear about the Fuji system and their fast primes and great selection of wide angle lenses
