My standard kit - OM 2n or OM 2sp, 24mm f/2.8, 35mm f/2.0, 85mm f/2.0 fits easily in a tiny camera bag.
My other lenses include a number of 50mm (1.8, 1.4, 3.5 macro) that are very good and a surprisingly good 75mm - 150mm f/4 two touch zoom.
My OM20/OMG bodies are great, cheap backup bodies that are very light but very functional.
And in the past, my OM 1 bodies were very reliable.
The OM ergonomics are quite different from other cameras - really well suited to my strongly left handed needs.
