I agree.The way that lens draws is a wonderful thing.
I always recommend it as a first lens to go with your m43 camera, if anything, as a barometer of what you should expect other lenses to be in terms of rendering.I agree.
The 20mm f/1.7 pancake is probably one of my two all-time favorite micro 4/3 lenses - the other being the even more visually scrumptious 15mm PanaLeica. My 20mm was the 1st gen, which supposedly suffered from slow (or slower) autofocus issues, not that I ever noticed any - and in terms of size, it always seemed to make an already small camera body....even smaller.
But it 'draws' and renders quite beautifully.
