Thanks CH for that great test.? Quite a thorough OM macro discussion including?
pertinent Walt insights.? Thanks for that, Moose.
Somehow I couldn't abide not having a Z. 50 f2 and a kind list member sold me a
copy.? The bokeh is often better than the Z 50 1.4 high sn, but not always
wonderful.
Just to fill in a few other options in the 90 range beside the very nice but
very expensive Zuiko and the already mentioned Tamron 90 2.8 (or 2.5 for that
matter) is the 90mm viv S1 with the optically matched TC to go 1:1.? Detailed
analysis of it on Pnet a few years ago showed it was about the same as the
Kiron that Moose has but slightly more contrast where the Kiron had a touch
more res at 1:1.
The ability to go 1:1 w/o Tc is a plus for the Kiron.? Have used the 90mm Viv1
on occasion at near infinity and it works well as expected of such as highly
corrected lens, but is very subject to loss of contrast.? Paul had mentioned
this and the Hama hood knock off is a superb help.?? Suspect Moose doesn't
exercise the Kiron too much but uses his nice Tam with auto aperture on the 5D.
Have only used the Z 135 F4 macro on the autotube a few times at infinity, and
seemed very nice, if a bit slow and large for the purpose.
The CV 125 f2.5 macro in OM mount (Big Foot) is nice at infinity but has a
trace of CA at 1:1 which really hasn't been a problem.
The bokeh is just stellar.? It is now getting very hard to get and have seen
"fool and his money" prices for one in Nik mount on yabe---2K for one a couple
wks ago.
One oddball I had forgotten about? is the? Viv S1 macro 90-180mm.? I recall it
took Jeff a year or so to find one in OM mount.
It is nice that he max mag (IIRC) is at the long end.? I don't remember seeing
any posted images on the list, but someone must have one.
It must be a bit of a behemoth but quite unusual.? I ran into the below images
on FM which piqued my interest.
