Power lines - Quantaray m42 lens
These are from my second time messing with a Sony A7R IV paired with an old Quantaray Auto Zoom MC 28-80mm f1:3.5-4.5 Macro m42 screw mount lens adapted to E mount with a Neewer adaptor. Lens is No. 270248. Talk on forums indicates this was perhaps made by Sigma in the 70s or early 80s.
Note the amount of vignetting in the corners when this lens is zoomed out at 28mm. Maybe this could be corrected in Lightroom with the right settings. This lens might work better on an APR-C sensor camera, but if maximum IQ is the goal, this is the wrong lens. Taken at f/5.6
