Which optical consequence affected early camera obscura image quality derived from a single, uncoated plano-convex lens?

💡 Explanation

When early camera obscuras used simple lenses, white light dispersed because each wavelength refracts differently through the uncoated lens material, leading to chromatic aberration and colored fringes. Therefore chromatic aberration resulted, rather than spherical aberration, vignetting, or astigmatism which are caused by lens shape or aperture issues.
