Olympus - Fast, Fast Glass.

I was impressed by Olympus' growing line of lenses for their DSLR systems. The first is the 35mm equivalent of a 300mm f2.0. Yes, you read that right.<p><img src="http://gallery.photographyreview.com/data/photography//534/olmpus_150mm_2_0.JPG" alt="Olympus Zuiko Digital 150mm f/2.0 lens"><p>This 150mm f2.0 lens in the Four Thirds system turns into the 35mm equivalent of a 300mm f2.0. Very, very impressive by anyone's standards.

Also of note was this 35-100 f2.0 which turns into a 70-200 fixed f2.0...<p><img src="http://gallery.photographyreview.com/data/photography//534/olympus_35-100_2_0.JPG" alt="Olympus Zuiko Digital 35-100mm f/2.0 Zoom Lens">
