The 7.5mm fisheye provides 180 degree angle of view. This lens can only be used with the mirror locked in the up position, hence a seperate view finder is provided for viewing. The serial number begins at 750011 and ends at 752222, suggesting a total production of 2212 units. This example is the 36th lens from the last.


There are six built-in filters in an internal turret: L1A, Y48, Y52, O56, R60, X0.
