Improvements achieved for a more stable optical
performance across the entire zoom range
The optical design has been completely overhauled in comparison with the previous model
(A009), and superior performance and resolution is now ensured across the entire zoom range.
Outstanding optical performance that is uniform and well-balanced is maintained, not only in the
70mm wideangle range but also in the middle focal ranges and the 200mm telephoto range.
Using the A025 in combination with a dedicated tele converter attached makes it possible to fully
enjoy ultra-telephoto photography while maintaining excellent optical performance.

With transverse chromatic aberrations minimized, improvements have been made in the
periphery of the image plane on the wide-angle side.

Improved depictive quality in the telephoto focal range
Deploying the LD lens element has minimized axial chromatic aberrations occurring
on the telephoto side.
