seedhe started the topic What's the difference between 50mm Summicron v4 vs v5? in the forum General Leica Discussion 1 month ago
I read reviews on Kenrock said optical is the same, V4 have focusing tab, V5 have built in hood and 6 bit. Is V5 have more modern coating compare V4? And one more question how Summicron IQ render compare Summilux?
