Nju apmeeram sapratu kas tas par zveeru APO, kjip nekropljo kraasas tik ljoti, kaa to varbuut dara stikls bez APO, varbuut avru redzeet kaadu saliidzinaajumu bilde (ar APO) un bilde (bez APO). Nu taa kraasu kropljoshana cik lielaa meeraa!?? :?
APO: Also “apochromat.” A lens designed to minimize chromatic aberration by bringing three wavelengths of light onto the focal plane.
This type of lens offers superior correction of chromatic aberration to the typical achromatic lens and was invented in 1868 by Ernst Abbe (1840-1905) of Carl Zeiss for use in microscopes. Note, however, that the term is used fairly loosely by some lens manufacturers as a marketing feature, and does not necessarily guarantee high optical performance.
nu garais objektīvs no tehniskā viedoklja nav nekas sarežģīts, nikkor 70-300 G arī maksā kādus 150 doļus, bet bez ED stikla bildes ir samērā kakainas tieši krāsu un aberāciju dēļ.
dārgie - protams, daudz labāka optika un līdz ar to arī rezultāts.
