Should you automatically apply Lightroom lens correction profiles on import?

If Lightroom correctly identifies my lens and has a built-in profile for it, is there any downside to automatically enabling lens profile corrections on import for every photo? I’m mainly wondering whether this always gives a more accurate result, or whether there are trade-offs such as loss of sharpness, detail, or image area after distortion correction and cropping.

Most post-process lens corrections will cause a loss of detail, as they are not just modifying how the raw pixels are interpolated and what mathematical curves and adjustments may be applied...they change the position of pixels throughout the whole image. At the very least, you'll lose some amount of sharpness, and fine detail may be lost in some areas of the photo. Unless you have some very specific need, such as a photograph of a brick wall that is clearly demonstrating barrel or pincushion distortion, or pronounced CA, generally speaking I would avoid applying any lens profile.
If you want a simple rule of thumb...if your photo is clearly unacceptable without lens profile correction, and acceptable with it, then use a lens profile.

Yes—there can be trade-offs, so it’s not always best to apply lens corrections automatically to every image.
Main downsides:
- Distortion correction warps the image, which can slightly reduce sharpness or fine detail because pixels are being remapped.
- Correcting distortion usually leaves an irregular image shape that then gets cropped back to a rectangle, so you may lose content near the edges.
- The benefit depends on the lens and the photo. Some images clearly improve; others may not need correction.
Upsides:
- Profiles can reduce visible barrel/pincushion distortion, vignetting, and sometimes chromatic aberration.
- With some lenses, any sharpness loss may be very small or hard to notice in practice.
Practical approach:
- Don’t assume it’s always better just because a profile exists.
- Check at 100% and toggle the profile on/off.
- Use it when the uncorrected image is clearly worse and the corrected result is acceptable.
- Leave it off when edge cropping or any loss of detail matters more than the distortion.
