Olympus 100-400mm f5-6.3

Just got this lens and been out and about it is very sharp .I shoot raw and do not have to do any or in some case very little sharpening in my photos .I find it quite easy to hand hold at very low shutter speeds .It weighs slightly less than Canons 100-400mm but is slightly longer .But it is a 200-800mm on the Olympus body so you can get a bigger image without getting too close .The zoom is lockable and also has three lens settings to help having to zoom from closest to furthest every time. It is weather sealed so great for all weathers.
