Preferred use: Close-ups of all kind, products, industrial, documentation, copy work, digital photography.
Optically, well-designed makro-lenses like the Makro-Planar 4/120 HFT PQS lens differ from other lenses in two ways.
First: Their performance is optimized for subjects like the one you're just looking at: A flat page slightly larger than a human head with intricate detail. Which means, the image quality and light distribution of the lens is extremely good, even in the corners and even at full aperture. This is exactly what is needed for serious professional copy work of subjects that are smaller than the ones ideally photographed with the Planar Rollei 2.8/80 HFT PQS lens, e. g. delicate drawings (so the two lenses complement each other very well in the hands of the demanding photographer).
Second: A basic type of lens design is chosen that maintains its performance characteristics very constantly on a high level over a wide range of reduction ratios or distances. Like from half life-size (1:2) to infinity, in the case of the Makro-Planar 4/120 HFT PQS lens. It is based on the Planar lens design type, which offers very good close-up potential and is therefore also chosen as the basis for the ultra high resolution Carl Zeiss S-Planar lenses for the semiconductor-industry, which are, as of this writing, the most sophisticated lenses of our day.
