Some 100mm comparisons. Part II


Distant focus. Just short of ∞ focus

Only ZE MP100/2 and OM Zuiko 100/2, I\'ve put the Tokina D 100/2.8 away for now as I know all I want about it.

It doesn\'t show very clearly but at F2 the focussing experience with the ZE is far crisper/higher contrast than the Zuiko

All 100% crops

ZE F2
OM F2 I expected this to look much lower contrast against the ZE, it certainly looked it on the LCD in Live view.



ZE F8
OM F8 Shallower depth of field again showing. Great sharpness from both at this near ∞ setting


ZE F22
OM F22 Even at smallest aperture the diffraction effect is\'n\'tt as large as I\'d expected.

I think it\'s fair to say from this that both lenses perform admirably at distance setting.

One difference apparent, the ZE EF aperture stops are whole, even stops throughout the range, this is far from the case with the Zuiko:
Between aperture stops F2 and 2.8 there is only 1/3 stop reduction, From F2.8 - 11 the stops are full and even, then between F11 and 16 1 1/3 stops, and between F16 and 22 1 2/3 stops!

This on a lens recently serviced and given an A1 health billing by Olympus OM service centre!

(My Rokkor MC 24mm F2.8 has similar irregularities, but not the MD version. Perhaps it\'s common with \"old\" manual lenses?)
