Trioplan 50mm f/2.8 II 50mm

Its revised triplet design with coated Schott glass and a 12-blade diaphragm produces the signature soap bubble bokeh with improved contrast and central sharpness. The manual-focus lens now includes a close-focusing function down to 15.7 inches, adding versatility to its distinct vintage rendering. This lens is best for portrait photographers who prioritize unique, swirly background blur over modern optical perfection.
