Schneider's premium APO macro lens — the Componon HM 90mm for high-magnification repro work.
The Schneider APO Componon HM 90mm f/4.5 is a premium high-magnification repro and macro lens from Schneider-Kreuznach. The APO designation indicates apochromatic correction. The HM stands for High Magnification — optimised for close-range work at higher magnification ratios. A specialist scientific and reproduction optic.
Optical performance is outstanding for close-range work — the APO correction virtually eliminates chromatic aberration at high magnification. Flat-field correction ensures edge-to-edge sharpness when reproducing flat documents and artwork. The HM designation means it excels at magnification ratios where standard lenses falter. Schneider's finest close-range optics.
No standard camera mount — process lens mount. Weight varies. Build quality is outstanding German Schneider precision. The APO Componon HM can be adapted to digital cameras for exceptional macro and reproduction work — the APO correction provides reference-class results when properly adapted with bellows or extension tubes.
Available at very low prices despite premium quality. Adaptable for outstanding digital macro. The APO correction makes it one of the finest options for high-magnification digital macro work when adapted. Best for scientific imaging, document reproduction, and extreme close-up photography with proper adaptation.
