p.1 #1 · p.1 #1 · Olympus 21mm f3.5 single or mutli-coated?


Hi Forum

Thanks to all who gave me some good info on the comparison between this little lens and a few others on a recent question that i asked.

Which olympus 21mm are single coated, and which are multi-coated? This relates to the serial numbers on the lens or so i have been told.

I could not find any posts on this, however if there is, please direct me in that direction.

Thanks
Karl

As I understand it, the ones with G Zuiko on the front plate are single coated. The ones with Zuiko MC are obviously multi-coated. I don't know if they ever dropped the MC on this one like they did other lenses, but if it's just Zuiko, I think it's safe to assume it's multi.

Thanks for your input. Yes that is what i had heard as well.

I am also looking for the serial number batches that relate to the single or multi-coated versions.

Hi Karl,

Here's a link, https://www.fredmiranda.com/forum/topic/750634/0&year=2009#6841642

/begin{quotation}

Here's my (Laminin's) take on serial numbers for the ZUIKO 21/3.5 lens:

OLYMPUS OM-SYSTEM G.ZUIKO AUTO-W 1:3,5 f=21mm sn (chrome nose) single coated
(no M-SYSTEM lenses)
100146 lowest sn
107981 highest sn

OLYMPUS OM-SYSTEM G.ZUIKO AUTO-W 1:3,5 f=21mm sn (black nose) single coated
108181 lowest sn
116430 newest

OLYMPUS OM-SYSTEM ZUIKO MC AUTO-W 1:3,5 f=21mm sn (black nose) MC
114382 lowest sn (overlaps with G.ZUIKO range, but seems that there are two distinct MC batches within the late G.ZUIKO series)
118334 highest sn

Zuiko (black nose, multicoated, but not marked with MC)
OLYMPUS OM-SYSTEM ZUIKO AUTO-W 21mm 1:3,5 sn Japan
118444 lowest sn
1254xx highest sn; last production April 2003

/end{quotation}

Cheers, Jim

I wouldn't worry too much about production/serial numbers, if its multicoated I think you'll be happy, I know I am.

Jim, this is great information. I have also extracted some of the records before "Dementia Olympus" was taken down. Note that there are many variations of multi-coating colors within the same "version".
