If your lenses need digital corrections, don't leave it to someone else to fix

Embedded lens corrections
This is what the Canon RF 24-50mm kit lens looks like at 24mm without correction. This should be Canon's job to fix, not third party software vendors. (Image credit: Rod Lawton)

Digital lens corrections are a fact of life with modern day optics and camera systems. Many older lenses and traditional primes from makers like Laowa, say, still rely completely on optical corrections for distortion, corner shading and chromatic aberration, but the modern approach is to combine optical lens corrections with digital corrections, typically for corner shading and distortion, applied in-camera, so that you might never be aware it's happening

I don't have a problem with this. I've tested and shot with many modern lenses that give much better results (no, really, much better) by combining optical and digital corrections than older lenses relying on optical corrections alone. This is especially true with zoom lenses, especially those which are inexpensive, have a long zoom range or a retracting design.
