Are you using it on the A6000 or did a A7 find it's way into your house?
Both. I'll use the A7 with the 70 Sigma Macro at 1x for one shot of 35mm. Same lens on the A6000 for three- or four-way stitch occasionally. This lens is terrific.
So are some of my M39 enlarging and copy lenses, but I have encountered some flare problems with certain film holders with these lenses; no flare w/70 Sigma.
