There is some difference among early F4 version, zebra F4 version and F3.5 MC & F3.5 PB version. Compering only F3.5 models I think MC is the best. Followed by
zebra. PB is good, but coating (admittingly more resilient to cleaning liquids) enhances color / contrast in somehow strange way. Some might like it and it was a applauded in film era, but digital sensor is different story.


I was wondering if you know what is the "correct"/accurate color cast of the good/better coating found on these CZJ 135mm MC lenses. Thank you!

The accurate colour cast is no colour cast at all.
Though the most common cast is either being a bit warmer or cooler than neutral, this is simple to fix in post, Lightroom has an eyedropper WB tool that can remove any colour cast in one click, your AWB in the camera may correct the cast too.


Oh what I meant was the color on the coating itself on the lens. Not the cast on the image output.

Reason being I've been seeing mostly reddish/orange coating on the lens while some have bluish/purplish coating on ebay.

MC vs. PB Coating can appear similar on photos but body cannot. It is altogether different. Not to mention the mount.

The last black 3.5/135 versions called MC have a red cast in the coating, i have only seen this with this model, it's a very good lens.
In the second picture you can see another "red coated" MC (top right) and an old 4/135 on the left next to it, which has no red cast (single coated?).
