Luo Degang is an old optical manufacturer in Germany, and some specifications of photographic lenses are as famous as Zeiss, Schneider and Rotundus. As far as enlarger lens is concerned, he is very famous in the industry. It can be said that his magnifying lens, whether it is morning, evening, professional, ordinary or APO, is of high quality and is a rare boutique in darkroom hardware in the traditional photography era.
Moreover, there are not many single-layer coatings on Luo Degang's amplifier head. Only 50mm f2.8 has single-layer coatings and multi-layer coatings, and the weight is different. Multilayer coating is relatively lighter and there are more plastic parts, but there will be obvious luminous display of aperture scale in the darkroom, which is very convenient. Theoretically, multilayer coatings should be produced in the later stage.
As for the collection, enlarger lens has long lost its original aura. Whether it is early or late, it is inconvenient to use at present. If the seller's price is not high, both are acceptable, because both are good things.
