Design and Features
The RE. Macro Auto-Topcor 58mm F/3.5 lens, for use with the TOPCON RE Super and RE-2 cameras, has been specially designed to give optimum lens performance at close focusing distances and in macrophotography, as opposed to the 58mm standard lenses which have been designed for giving optimum performance at infinity.
Optically the lens is of Xenotar type and designed to give distortion-free images of the highest resolution, with full illumination from edge to edge, and with best results obtained at the magnification 0.1X, while, at the same time, equalling the normal standard lens in performance at infinity.
Further continuous focusing, from magnification 0.5X to 1X (or life-size) can be obtained by simply using the TOPCON RE. Auto-Ring between the lens and body, which will, at the same time, couple the automatic lens diaphragm mechanism of the lens and the body.
