Should You Fix a Vintage Lens' Flaws in Lightroom?

Adapting a vintage lens to a mirrorless body gets you inexpensive, well-built glass with a look modern optics rarely have, and it also brings purple fringing, darkened corners, and lines that bow at the edges. Every one of those flaws can be pushed around in Lightroom, so each one becomes a decision about how much of the old lens you keep in the final file.

Jason Row of Rowtography works through that decision with two adapted lenses, a Canon FD 200mm f/4 and a Minolta MD 35-70mm. Both turn out to be stronger performers than their age suggests, so the corrections are small. The 200mm frame comes first, with visible purple fringing along high-contrast edges. An adapted manual lens passes no information to the camera, so Lightroom has no lens profile to pull, and the cleanup happens by hand in the Manual tab of the Lens Corrections panel. The Defringe controls handle most of it, with separate amount and hue sliders for purple and green fringes. With the fringing gone, the cobwebs strung across a railing in the background stay crisp.

Vignetting gets a similar treatment on a frame shot with the 35-70mm on a Sony a7R V. A full frame lens on a full frame sensor shows corner falloff more readily than the 200mm on a Fujifilm APS-C body, which only uses the center of the lens' image circle. To make the problem easier to see, Row drops the exposure until the darkened top corners of the sky stand out. The Lens Vignetting amount slider then does the work. Slide it right and the corners brighten. Slide it left and they darken, which makes it the same tool you'd reach for when adding a vignette on purpose. A small push to the right evens out the sky, and the Midpoint control, which sets how far the falloff reaches toward the center, barely needs to move for this kind of fix.

Adapted lenses sit outside the system that quietly corrects most modern glass. Many current mirrorless lenses are designed with software correction in mind, and their distortion and vignetting fixes travel with the raw file and get applied automatically. With some Fujifilm and Micro Four Thirds files, Lightroom shows a built-in lens profile that can't be switched off at all. A vintage lens on a simple adapter sends no lens data, so you start from the raw optical result every time. That makes per-lens presets a practical habit. Shoot a brick wall or a tiled floor at a few apertures with each adapted lens, find the defringe, vignetting, and distortion values that neutralize it, and save them as a preset named after that lens. Apply it on import, then pull it back on the images where you want the old character to show through. Because the adapter writes no focal length or aperture to the metadata, typing the lens name into the caption or keyword field during import saves you from guessing months later which lens made which frame.

Distortion is the last correction, demonstrated on a 35-70mm image full of geometric shapes. Dragging the Distortion slider left bows straight lines outward into barrel distortion, the look of an image wrapped around a barrel, while dragging it right pinches them inward into pincushion. Before touching that slider, Row levels the frame with the crop tool's angle tool, tracing along a railing that's known to be straight. From there, the goal is to line up verticals and horizontals you know are true against the grid overlay, and a setting of around +15 brings the railings into line. Toggling the correction off and on shows how much of a difference that small adjustment makes. Some problems resist this approach entirely, including wavy distortion that curves in more than one direction and certain kinds of chromatic aberration that the sliders can't fully catch.
