With a high-quality lens, pictures have stunning detail, high resolution, and sharp contrast. Alternatively, low-quality optics tend to produce softened edges — particularly with wide-angle lenses — more chromatic aberrations, and distortion.
With the full-frame sensor of the 5D Mark II, the need for the best glass is especially important because at full-frame, 21.1 MB resolution, any defects in the lens performance show up immediately in terms of soft or darker corners. As most photographers know, over time, the investment in lenses far exceeds the money invested in camera bodies. For this reason, making studied decisions on lens purchases pays off for years to come in getting great image sharpness and quality.
