I recently acquired this lens and it was put away for a couple of months, like so many of the lenses I bought. While doing some organizing, and I noticed this very large and heavy lens. Decided to give it a try and I was surprised to see that it's quite a decent lens. Very unique is its macro mode. Although it does not say what magnification ratio this mode provides, but I would estimate that it's at least 1:2.

Curious, I put it side by side against the Canon 70-200mm f2.8 IS and they look almost the same size, even about the same weight.

Will update this gallery as I have time to use this lens.
