The Hugo Meyer & Co Gorlitz Megon 100mm f/2 is not directly reviewed; the excerpts discuss the Meyer Optik Goerlitz Trioplan 100mm f/2.8. The Trioplan is known for its distinctive 'bubble bokeh,' an aberration that creates superimposed mirror images, which is either loved or hated. Optically, it uses a Cooke triplet design with three lenses in three groups; later versions (c. 1960) improved performance with a high-index lens but retained the same formula. Build quality varies: the new Trioplan has a titanium grey limited edition with a special anodizing process for high resistance, priced significantly higher than the black version. The lens suits photographers seeking a unique, cult-like character rather than modern smooth bokeh.
