I have the opportunity to pick up a used (mint condition) copy of the 70-300mm DO for ~35% less than the going retail cost. At retail cost, this lens is rather unattractive. I've got the focal range covered with L-series zooms (70-200mm II± 1.4x TC,100-400mm). But the 70-300mm DO is shorter and not significantly heavier than the 24-105mm f/4L - a lot of reach in a small, light package. It's clearly a trade off between IQ and portability- but, is it a worthwhile tradeoff?


All comments, and especially those from users of the 70-300 DO, are appreciated!
