TaoTeJared" .. .I'm personally not liking the "big" primes or how large prime lenses are becoming. ....for street shooting, smaller is better....
Since joining NRF I have became aware of something called street photography which, as far as am aware, is photographing people in the street I think Henri Cartier-Bresson 1908 -2004 ) may have stared the trend, using a Leica Tony Ray-Jones ( 1941 - 1972) was a master at it As is Martin Parr
But why do you need a pancake lens ????
In my experience if you have a camera, no matter how small or large, you are going to get noticed
The good new is today, so many people carry camera, people are so used to having the friends pointing smart phones at them and have now become aware they have probably already been caught on CCTV 50 times today, it really is not a big issue
