Enjoyed reading Moose's well organized, illustrated treatise and noted Jan's
Clearly MFT is up to the job and focus stacking would almost be essential in
many circumstances. I would not totally dismiss special "rendering"
characteristics of some macro lenses (esp w/o aspheric elements) but suspect
that would matter much less for document shots, nice though they be.
The use of a very long zoom that is close focusing to improve working distance
bespeaks the lack of a long FL macro lens for MFT, though the former does work
(yes, did use Greentoe to purchase the PL 100-400 and use it on occasion with
the Pentax T132 achromatic CU).
<<You ask how the Luminars, and others will work with the E-M5. If you've been
following AG, MikeG, me, and others, and if you surf the web, you'll find that
some MF lenses work well with some digital backs, and come <<combinations work
Yes, hard to predict. MFT has a quite thick sensor stack but that should not
matter as much for macro. The OMZ 80mm bellows lens seems to behave better on
FF than a brief trial on MFT
in a quick contest OMZ 80 vs the 60/2.8 at 1:1 that I recall took place on
our kitchen table during a Moose visit. The 135/4.5 does behave well on Canyon
FF and Jan says on MFT too. (pleased that is so)
This was a very quick stack outside near our lavender hedge--had 45 min of
free time from soup to nuts.
As a bellow lens it obviously does not change FL so working distance maintained
at the cost of more light loss. Even Big Foot uses some FL shortening. The Z.
135/4.5 has a large image circle (designed to be used on the tilt-shift bellows
that never made it on the market) too so I can mount it on my Mirex tilt-shift
adapter. I can also mount it on my tilt-shift bellows with OM fittings but
that is quite fussy. I am told the bellows may have been re-branded after
initial production in the secret Wyoming factory. ;-)
Curiously Oly has enabled all 5 axis IBIS even for non-system lenses where Sony
requires focus distance to be reported else 3 axes only stabilized. I very much
doubt over 5 stops of IS with non system lenses as that is for lenses with sync
IS like the 12-100--that is indeed impressive. I think by my reading Jan at
times conflates focus bracketing which can be done automatically on some Oly
cams or even manually-- followed by focus stacking the images using software
with in cam focus stacking--the latter is limited to a few lens/cam combos and
allows 8 images only---result in jpeg output only too. Much too restrictive
for my tastes. Would not totally dismiss 'pod use as IS does not provide axial
stability which might be essential nor r/o use of flash. The new Oly STF-8
twin macro flash will support focus bracketing/stacking and one can pick a
delay time to allow for flash recharge. Trouble is, the cost is adding up
