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.

Sigma description:

Designed for use with full frame digital SLR cameras. May also be used with smaller APS-c size sensors with a corresponding effective increase in focal length to about 150mm with most cameras

Focuses down to 1:1 magnification ratio at its closest working distance of 12.3 inches

Extremely compact weighing only 16 ounces & measures only 3.8 inches long.

A lens hood, front & rear lens caps and carrying case are included with the lens.

I will take actual photo of the lens and post it soon. 🙂

Depth of field of medium telephoto macro lenses is generally very shallow; however, Sigma, Canon and SONY mounts of this lens have a minimum aperture of F45 (or F22 for FOUR THIRDS or F32 for Nikon and Pentax mounts) for incredible depth of field.
