and these schemes actually prompt for an obvious question:

  • at the time of the RX-1 announcement it was argued that its 35/2 lens ​needs to be fixed​ as otherwise it won't be possible for it to have such a huge back element;
  • but that seems to be in a direct contradiction with the schemes you show here, esp. for the 22/2
  • so... can modern design reconcile interchangeability and extremely wide exit glass?

Here's another attempt.

Sigma 30mm F2.8

Canon M 22mm F2
