Does anybody own an original lens shade (rectangular) for the 75mm Zeiss Biogon? If so, I would be interested to know the dimensions of this hood so I can build one...or similar. Data like extensions beyond the front lens flange, size of th e long and short wings on the front, etc. I intend to use the Lee FK-100 lens fl ange as the mounting mechanism and build the wings in my machine shop. Thanks in advance for any assistance. Please contact me off line, at: boulware-den@att.ne t. Be well, Richard Boulware Photography - Denver.
