(not mine - just FYI)

How is this compare to Nikkon Series-E 100mm f2.8 or even old Elmarit-R 90/2.8... I have few in this range (including Jupiter and Helios), and unless moving to very expensive APO like lenses, I am not able to think any greatness in this...

Moving to f2.0 is different ball game...

Couldn't tell ya. I'm happy with my Nikkor-PG 105mm f2.5 - absolutely brilliant lens.

Hurry for what

Not much of a deal there. The lens is an early silvernose version, single coated. That lens is no comparison the the Zuiko 100/2. I know, I've had them both.

PG-?? I have Nikkor-P 105mm f2.5 (or that may be PG)...
Yes, superb lens... Mine is very beaten up copy (got cheaply)...

Nikkor-PC actually (The C indicated NIC multi-coating).

+2 on the Nikon 105. It can't get much better.

The Oly 100/2.8 is a nice lens, but not spectacular. Not that sharp below f/4. Its biggest strength is it's size, which is about the same as most 50mm lenses. I've used mine a lot on the E-1.

+1 for size. But again, in my scarce knowledge of other lenses, it is unbeatable for a $80 lens.

I thought we were going to talk about the Oly 100/2.

Hard for it to beat the similar priced Series E 100/2.8, which is stellar.
