In the past l have shot with 5cm Summar and a 5cm Elmar, soon to arrive is a 3.5cm Elmar, how can l tell if it is a nickle finish Elmar, what do l need to look out for. Below is an attached image of the incoming , apparently the glass is clean and the marks on the image is just external dust, (we shall see ) It certain look uncoated😀 Thanks in advance for any halp
