We once conducted a survey amongst ourselves of all our lenses in an
attempt to define what was multicoated and what was not by serial number
and other identifying characteristics. Here are the results for 35/2.8
Focal Aperture S/N Chrome/ Coating MarkedMC? Lens Name
Length Black
-------- ---- ------ ------ ------- --------- ---------
* 35 2.8 102000 Black MC Yes Zuiko MC
35 2.8 129700 Chrome SC No
35 2.8 141114 Chrome SC No G. Zuiko
35 2.8 145960 Chrome SC No G. Zuiko
35 2.8 149151 Chrome No G. Zuiko
35 2.8 152700 Chrome SC No G. Zuiko
* 35 2.8 173122 Black MC No G. Zuiko
35 2.8 177594 Black SC No G. Zuiko
35 2.8 182901 Black SC No
35 2.8 190492 Black SC No
35 2.8 213828 Black SC No G. Zuiko
35 2.8 230319 Black SC No X. Zuiko
35 2.8 246000 Black MC No G. Zuiko
35 2.8 251229 Black MC Yes Zuiko MC
35 2.8 252042 Black MC Yes Zuiko MC
35 2.8 260800 Black MC Yes Zuiko MC
* 35 2.8 277800 Black SC No Zuiko
Note that there are some apparent outliers here which I have marked with
an asterisk. 102000 is probably too early to be MC but the lens is
clearly marked MC. 173122 doesn't seem to fit its surroundings and
277800 should certainly be multicoated at that high serial number. The
rendered judgments could be wrong, or repairs might have changed serial
numbers, lens barrel color or name ring markings. Nevertheless, one can
probably conclude that (barring changed parts during repairs) 35/2.8s
with serial numbers of 251229 or higher are most probably multicoated
even if it doesn't say "MC". I just noticed that my own 136904 didn't
make it to this list for some reason. It's not MC.
