The Cost and Benefits of Lens Correction Using Software Techniques

The above is simply wrong, or at least overstated. Olympus m43 lenses all employ software correction. What they don't provide is software correction of CA, but the definitely make use of correction for other aberrations. And Panasonic lenses don't rely solely on software correction. Their lenses could be much simpler in design if they did, and they wouldn't need the expensive glasses and aespherical elements if they weren't doing optical correction as well as software.

Whether Olympus lenses have more optical, and less software, correction than Panasonic lenses depends, I suspect, on the specific lens(es) being compared.
