<p>Hello, I have inherited a Meyer-Optik Gorlitz Trioplan 100mm F 2.8 ( this lens is known as the "soap bubble lens", due to its distinctive bokeh when shot wide open at 2.8. After doing some research on the lens it would appear to be manufactured between 1952 and 1959. serial number 2156787. When researching the iris design I find a 15 blade type was used, but oddly this lens has a 10 blade type. Has anyone ever seen this. Is aperture blade replacement something that would be done normally? thanks for your help</p>
