John, thanks very much for your well-considered response.
You make an interesting point about matching the lens with your way of
seeing. I find
that the 100 seems to be nearer my own magnification than a 50mm which is
supposedly
meant to match human vision. Does this mean i'm long-sighted or
telescopic!!.
Comparing the viewfinder image with my own if anything the 100 image still
looks further away.
Does the viewfinder give exactly the image that appears on the print.
I like the idea of the 85 f2 since it is small enough to fit within the
standard
camera case (the 90 macro isn't). With the extra stop and close focusing
correction I hope it ideal for some of the close up landscape images I
attempt (sun shining through leaves in wood clearings etc).
Also I hope it slightly more suitable for portraiture as I will be able to
get a bit nearer the subject, of course I'll use that focal length for
practically all of my landscapes.
I hardly ever use the 28mm but I've used the 21 quite a bit, though I'm not
a great fan of wide angles.
Regards
Richard

Subject: Re: [OM] 100 f2.8 vs 85 f2
Back more than a few years ago, when I first got into photography, I was a
big fan of Herbert Keppler. Never missed his column in the old Modern
Photography. Mr. Keppler was very enamoured at the time with the 28mm,
50mm,
100mm lens trio. Remember this was when zoom lens was still a dirty word
among serious photographers. Naturally I had to follow my hero's advice and
I purchased the 28mm and 100mm to supplement my 50mm.
I soon discovered two things. The 28mm and the 100mm did not match my way
of
seeing. I found the 100mm to be just slightly too long or just slightly too
short. The solution for me was to replace the 100mm with the 85mm and
135mm.
This better matched my vision. I had the same experience with the 28mm.
Either too long or too short, so I solved that problem with the 24mm and
the
35mm.
I've owned both the Zuiko 85mm f2.0 and the Zuiko 100mm f2.8 and found them
both to be very sharp and contrasty. I feel the 85mm has a slight edge at
close distances, but this would be expected because of the builtin close
focusing correction mechanism (floating elements). I would not, however,
say
the 85mm is an inherently better lens optically. I would choose on the
basis
of focal length. Also, don't forget that the 85mm is one stop faster, which
comes in handy in low light situations or for soft backgrounds in
portrature. Both the 100mm f2.8 and the 85mm f2.0 are excellent examples of
the lens makers art. Either way you can't go wrong as far as quality is
concerned.

John Austin
