OM System 40-150mm f/4.0 PRO M.Zuiko Digital ED

This lens is a jewel for its intended purpose - high IQ with max portability and lower price -. The reasons to buy the F/2.8 version are obviously its brightness and the ability to mount an MC-20 2x teleconverter which gives you an equivalent 160-600mm f/5.6. With the 8-25mm and 12-45mm f/4 pro zooms it creates a lens system from 16mm to 300mm (eq) that is unbeatable for portability at a reasonable price. For important shoots I carry both my OM1 and OM5. The 2 bodies and 3 lenses easily fit in a small backpack whose weight does not bother me even in long hikes. I paid $650 for an open box unit.
The excellent 12-100mm and 300mm are also f/4 but are in a different, much more expensive category.
