Aleha,

I'm shooting Olympus' Fourthirds system which allows for very compact and bright lenses.

I use the two very high quality zooms: Zuiko Digital 14-54mm f/2.8-3.5 and Zuiko Digital ED 50-200mm f/2.8-3.5 and the 1.4x teleconverter EC-14. This gives me a 35-mm film equivalent focal length range 28-560mm f/2.8-4.9 in a very compact package.

These lenses belongs to Olympus' "High grade" line of lenses which are water and dust protected and designed for higher resolution than currently available in the Fourthirds bodies. The optical quality is nothing but superb.

Cheers, Jens.
