Consider a used Alpa Kern Macro Switar 50/1.9 Apochromatic or an used Kinoptik 100/2 APO cost today, both is over 40 years old already and a brand new Kinoptik 100/2 APO cost at 5,978 euros before tax/VAT. I think the new 50 APO-Summicron ASPH price is right between among the top tier lens manufacturers. 😀
