My most recent 50mm/1.4 SN is 1086xxx. When I use a point source halogen light I get separate and distinct reflections in different colors and at different depths. From the front: lavender and aqua, lavender, purple, amber, red, red, green and yellow. From the back are green, yellow, green.

My 50/1.4 silver nose with SN 395xxx reflects, from the front: amber, yellow, red. yellow, red, blue, and lavender. From the back is blue, lavender, yellow, lavender, blue, red.

Were they coated the same on the front and back? I was also surprised to discover that my 24/2.8 and 50/1/4 were marked f=xx/x.x while the 50/1.8 was marked just xx/x.x. Any other lenses marked unusually?

1007xxx. It reflects bright green and bright purple. Fainter sort of gold
reflection as well.


Green/Violet/Red
with green being predominate.
