Showcase Sigma 39-80 f/3.5 Macro

  1. These were taken with a Sigma 39-80 f/3.5 Macro that has an OM SLR mount. I would not recommend this lens. It's heavy and slow to operate. The focus only turns 1/4 of a full revolution. It has a zoom ring that rotates 10° more than the focus. It has a "reproduction ratio" ring that adjusts from normal to 1:9 to 1:3.5. I found that to achieve focus at other than infinity, I often needed to adjust all 3 rings.
