Its Excellent SQF results were drastically superior to the earlier lens, especially at 50mm and 70mm, indicating much more sharpness and contrast. Distortion, according to DxO Analyzer 3.0.1 tests, was also vastly improved, with Visible barreling at 24mm (0.39%), versus Very Visible (1.2%) barrel distortion before. At 50mm pincushioning was Imperceptible (0.09%)-astounding next to the Very Visible (1.5%) pincushion distortion of the earlier lens. Similarly, the new lens showed just Slight pincushioning at 70mm (0.15%) compared with Very Visible (1.8%) pincushion distortion in 2002. This all suggests a complete rethinking of the lens. Light falloff was gone from the edges by f/3.5 at 24mm and 70mm, with no measurable falloff at 50mm. Magnification ratios at the uniform close-focusing distance of 13.4 inches ranged from 1:10.31 at 24mm to 1:5.34 at 50mm, and 1:4.35 at 70mm-disappointing next to the older lens' 1:3.6 top magnification, but the price of SQF and distortion superiority.
