The OM-4 is almost perfect. There is maybe no better light metering system and view finder display (at least in the analog world). The only real disadvantage is the frame coverage of "only" 98%. And you need a shop in your neighbourhood who sells batteries:-)

Zuiko 2,0/35mm: Beautifully designed, pretty small and lightweight for a fast lens: Length: 43 mm, weight: 240 gr., filter thread 55 mm. The Zuiko is a very well-made lens. The feel of the surface is excellent: The mount is metal with a thick rubber focus ring. Only manual focus. The aperture ring stop down softly (much softer than the 1,8/50mm). The depth of field button is attached at the lens down on the right. It is by far the best accessible position. The minimum focus is 30 cm. The smallest aperture is 16. The Bokeh is good http://www.pbase.com/ltolksdorf/image/120437496). The lens is a little soft wide open but sharp stopped down. Distortion isn't a real problem. Fall off is visible at 2,0 but not really a problem http://www.pbase.com/ltolksdorf/image/120408849). In summary the 35mm f2,0 is good but not as good as the Zuiko 50mm f1,8.
