I don't think that there is any overlap between the ZUIKO MC and ZUIKO only numbering range as claimed in jcolwell's list.


That's OK, but you're wrong.

Not to sidetrack the argument...er... discussion, does anyone have any information on the Zuiko 24/2? I just picked up one locally and I'm thinking it's multi-coated, but it's labelled 'Auto-W 24mm 1:2' with no reference to multi-coating. I'd also be interested in how it compares to the f2.8 version.

All versions of the 24mm f2 Zuiko were multicoated. Same with the 28mm f2.

Correct. (All multicoated. Same applies to all the f/2 lenses actually.)

Generally it should be better than the 2.8, however there weren't tests of it (24/2) in Modern Photography, PopPhoto, etc. so it's hard to back that up with numbers.

16-9.net may have tested them both?

I have both, so should test them sometime. One of the nice things about the 2.8 though is how small it is.

The only one I wasn't sure about was the 85 f2...

The ca. 15,000 early 85mm f/2 F.ZUIKO lenses with a chrome front were single coated.

Pop Photo has tested the 24/2 lens (see: http://brashear.phys.appstate.edu/lhawkins/photo/pop-photo-zuiko-tests.txt)

24/2 MC (7/84 p. 65):
Actual: 24.73/2.06, Distortion: above average barrel
Centering: near-perfect, Flare: 0.6%, Transmission: 94%
Percent contrast of 0.01mm slit image:
2 2.8 4 5.6 8
Center 51 76 82 83 83
1/3rd out 50 67 68 67 66
2/3rds out 44 51 55 50 55
Far edge 40 41 55 70 69

but not the 24/2.8 which was tested by Modern Photography (see: http://brashear.phys.appstate.edu/lhawkins/photo/mp-zuiko-tests.txt)

(sorry for the table layout; just check the link)

Ah, good point - forgot about that one. Indeed, that came in both versions. (I have one of the later MC variety, that I lucked into on ebay)

PopPhoto tested the 24/2.8 also (1975), his lists seem slightly incomplete...

Yep I know there is a SC silver nosed version of the 85F2, I think with sn up to 115,000 or so. I have the reference at home if it is critical. There are at least 3 versions, actually. The latter ones are probably sharper than the Z. 100 f2.8, though I had not appreciated that. The 85 is quite a nice little lens with a floating element--works fine with some extension as a mini macro kit and is a nice portrait lens. Jane Bown often used at at F2.8 to take her portraits of Queen Eliz. It is known in our house as the "Queen's Lens."

Thanks for the info guys. I used the lens a bit this past weekend, and it looks like a keeper.
