wide aperture telephoto in 135-150mm range for Micro Four Thirds
introduction
Olympus mZD 40-150mm f/2.8 Pro
Olympus ZD 50-200mm f/2.8-3.5 SWD for Four Thirds
-
AF will be stutteringly slow on most bodies, although the E-M1 will allow faster phase detect AF
very sharp lens wide open
at 135mm, the widest aperture is f/3.3
the problems are:
slow AF
big, heavy lens (1.07kg), and almost absurdly long when extended even to 135mm focal length when the hood is in place (10.5cm longer than the Canon EF 135mm f/2.0L lens with its lens hood)
-
requires four-Thirds adapter
advantages:
gives best telephoto range
close focus 1.2m
has tripod mount
nice bokeh for a zoom lens
can be bought at reasonable prices 2nd hand
can be used with Olympus ZD tele-extenders (EC-14 and EC20)
weatherproof
Olympus ZD 150mm f/2.0
-
a beautiful lens BUT AF will be stutteringly slow on most bodies, although the E-M1 will allow faster phase detect AF
very sharp lens wide open
the problems are:
slow AF
still expensive (>$A3000 new perhaps $A1700 2nd hand)
very heavy (1.6kg, 82mm filter)
for some reason it is substantially heavier than a Canon EF 300mm f/4L IS lens which gives the same field of view and DOF on a full frame dSLR and weighs only 1190g and uses a 77mm filter but the 300mm lens is much longer at 221mm
it has two big advantages over the Canon 300mm lens:
close focus 1.4m
requires four-Thirds adapter
advantages:
Canon EF 135mm f/2.0L
Olympus OM 135mm f/2.8
-
when compact size trumps AF
only 360g and 80mm long, 55mm filter
will need OM-MFT adapter
built-in lens hood
best stopped down to f/4 to reduce purple fringing
