This page describes the 45/2.8 GN:

There was no "E Series" version of the 45/2.8. There is, however, a Series E 50/1.8 which is quite compact and comes close to a pancake.
FWIW, for the majority of people a 45/2.8 on APS-C is not overly useful. Some will use it just because They Can™ and very few will actually find it useful. No need for a review, IMHO.
After all, there M-mount Voigtländers that are both smaller and faster if you account for the F-mount adapter you would need.
