I prefer big cars with room for at least 6 people, because I have 4 kids (mostly grow ups, but they like to join us on holidays). I don't think you can find a lens analogy for that, though
The only thing I miss on my M-50/1.7 is AF. I don't think this monster is the right solution to that - and it would weigh almost as much as all lenses that are permanently in my bag now (DA15, DA35 Ltd, DA70, M50/1.7)... (I agree with the above posters that 470 grams is probably well below the actual weight)
