  We present nine new binary lens candidates from OGLE-III Early Warning System
database for the season of 2005. We have also found four events interpreted as
single mass lensing of double sources. The candidates have been selected by
visual light curves inspection. Examining the models of binary lenses in our
previous studies (10 caustic crossing events of OGLE-II seasons 1997--1999 and
34 binary lens events of OGLE-III seasons 2002--2004, including one planetary
event), in this work and in three publications concerning planetary events of
season 2005, we find four cases of extreme mass ratio binaries (q<0.01), and
almost all other models with mass ratios in the range 0.1<q<1.0, which may
indicate the division between planetary systems and binary stars.
