Okay, one confession before moving further: I am second hand buyer! Yeah, because I don’t have enough fund to buy brand new items. 
Now moving on, I just bought a pre-owned Sigma 105mm EX DG Macro lens yesterday. The lens for Canon mount. Did a little testing and I took it home smiling.
Here’s sample video clip about the lens, and after the jump sample photos I took immediately to test the IQ of the lens. I am mounting it to my Canon EOS 5D Classic or some calls it Mark 1.

The Sigma 105mm can work both for full frame DSLR and likewise for the cropped sensors model.
