With the balance issues of a small camera and heavy lens, all of them feel about as heavy in your hand.
A camera with pro lenses will never be small and light because optics are constrained by physics. You literally can not make these lenses that much smaller. You're looking at negligible ~100g variations until you get to APSC which is also stop slower.
