Congratulations on your purchase, it is a very nice lens and provides very unique experience. I get a lot of joy using the lens.
For those asking abut CA, I have the 50/2 and 100/2 and based on some normal use experience, not lab testing, both produce about the same amount of CA. I actually find the CA on 100/2 slightly more noticeable, but that's probably because of the different type of photos I take with these lenses.
