In the close-up range, at scales of around 1 : 1, the quality of lenses optimized for larger distances falls visibly from the usual standard of performance. Here the Apo-Macro-Sironar lenses come into their own for imaging scales of 1 : 5 and greater.

Incidentally, imaging scales of 1 : 5 or larger are required even in conventional table-top photography or studio photography (e.g. pack shots): for example, 1 : 3 at a film size of 4 x 5 in. means the full format image reproduction of an object of approximately 30 x 40 cm (12 x 15 in.) in size.

The Apo-Macro-Sironar offers excellent imaging quality in conjunction with the wide freedom of movement required for perspective corrections of large-format photography. Due to the image circle diameter increasing with the reproduction scale becoming larger, this lens allows even more freedom of movement than lenses designed for greater distances.

The Apo-Macro-Sironar provides exceptional results without any color fringes at a scale range from 1 : 5 to 2 : 1 without any need to adjust the lens individually. The focal lengths of 120 mm and 180 mm allow work with most cameras without any extra monorail extension even at a scale of 2 : 1.
