pasirodo tu FF didesnis uz EF-S ir net EF.. ok, klaidinantis paveiksliukas..
atrode, kad bent ant plastmases tarp stiklu ir bodzio turetu susitaupyt..
kazkaip galvojau, kad tas paveiksliukas bent toki gabarita eliminuoja:

https://en.wikipedia.org/wiki/Micro_Four_Thirds_system#Micro_Four_Thirds_lenses
Because the flange focal distance of Micro Four Thirds 
cameras are shorter than DSLRs, most lenses are smaller and cheaper.

MFT shares the original image sensor size and 
specification with the Four Thirds system, designed for DSLRs. 
Unlike Four Thirds, the MFT system design specification does not provide 
space for a mirror box and a pentaprism, which facilitates smaller body designs 
and a shorter flange focal distance, and hence smaller lenses. 

Teoriskai tas "shorter flange focal distance" tarsi leistu "smaller lenses"..
Tik pagal gaminamus variantus kazkaip lengvai paklikinus kazkiek neradau patvirtinimo.
