In "steenkool-Engels" de eerste impressie:
The excessive expectation is bad for the lens. 18-270mm and 16-240mm are equal performance. In wide side, spherical aberration -0.2mm, astigmatism -0.2mm, distortion -6% of barrel types, chromatic aberration is +0.01mm. In tele side, spherical aberration +0.3mm, astigmatism -0.3mm, distortion +2% of spool types, chromatic aberration is -0.015mm. 18-200mm is slightly than them high-performance. In wide side, spherical aberration +-0.1mm, astigmatism -0.35mm, distortion -6% of barrel types, chromatic aberration is +0.01mm. In tele side, spherical aberration +0.3mm, astigmatism -0.15mm, distortion +2% of spool types, chromatic aberration is -0.015mm.
