Which focusing outcome occurs in early magnifying lenses when significant spherical aberration exists?

💡 Explanation

Blurring at the image edge results when using early magnifying lenses, because spherical aberration causes rays to focus at different points rather than a single, crisp focal point; therefore image quality degrades, rather than achieving ideal imagery at focus through aberration correction.
