As a semi-professional photographer, I have always been looking for a lens for almost all areas .... and found! The Sigma 50-500 DG OS HSM is certainly not a "lightweight" among the lenses. But however you get a lens with which you can cover most photographic situations. This combined with a two-stage high-speed optical Image Stabilizer and silent, fast HSM motor succeeds fast and precise focusing. Amazing and satisfy even the good processing without much play with good feel. I highly recommend this lens all photographers wishing to cover a broad range recommend highly.
