  We present 19 binary lens candidates from OGLE-III Early Warning System
database for the season of 2004. We have also found five 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 of this
and our previous studies (10 caustic crossing events of OGLE-II seasons
1997--1999 and 15 binary lens events of OGLE-III seasons 2002--2003) we find
one case of extreme mass ratio binary (q ~ 0.005, a known planetary lens OGLE
2003-BLG-235/MOA 2003-BLG-53) 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.
