3x telephoto zoom lenses for Micro Four Thirds
introduction
if you have an Olympus camera, go for the Olympus 40-150mm f/2.8
if you have a Panasonic camera, go for a Panasonic lens as it has OIS which will be needed in such a telephoto lens
Panasonic 50-200mm f/2.8-4.0 OIS
-
weathersealed
665g
$US1699
Olympus mZD 40-150mm f/2.8 Pro
-
high optical quality
MSC AF
weatherproof

Panasonic 35-100mm f/2.8 OIS X
Panasonic X PZ 45-175mm f/4-5.6 ASPH. POWER O.I.S HD
90-350mm in 35mm terms
HD = fast, silent AF for videos
-
PZ = Power Zoom = electric zoom lever for smooth zooming during videos
NANO surface coating for less flare
14 elements in 10 groups (2 aspherical lenses, 2 ED lenses)
Multi-Actuator Floating Inner Focus System
constant physical length across the zoom range
7 rounded blades
46mm non-rotating filter thread
closes focus 0.9m
61.6mm x 90mm long
210g
$399
-
maximum distortion uncorrected is 1.6% pincushion at 90mm but distortions are well corrected in-camera
1.1EV vignetting wide open at 45mm much less at all other settings
good to very good and consistent sharpness across all focal lengths although worst results wide open are for 120mm at the edges
minimal CA at 45mm but rises to peak at 1.7px at 80mm, but these are well corrected in-camera
“a good albeit not superb telephoto zoom lens as some might have hoped from its “X” designation”
-
Olympus m.ZD 40-150mm f/4-5.6R
Olympus m.ZD 40-150mm f/4-5.6
80-300mm in 35mm terms
closest focus 0.9m
13 elements in 10 groups
58mm non-rotating filter
internal focusing
63.5 x 83mm
190g
$299
-
soft edges at 40mm but excellent sharpness at 70mm and very good to excellent at 150mm
CA well controlled at max. 0.75px
vignetting well controlled at 0.8EV peak at 150mm
“excellent value for money”

-
Panasonic 45-150mm f/4-5.6 ASPH OIS
introduced in July 2012 as a more compact option than the 45-200mm and presumably faster AF, and it is the shortest lens in this group
90-300mm in 35mm terms
-
stepping motor makes focusing action smooth and silent for use in both video and photo recording
12 elements in 9 groups inc. 1x UHR and 2x ASPH elements
7 rounded blades
52mm non-rotating filter
closest focus 0.90m giving 0.17x macro
62x73mm
380g
$270?
-
Panasonic 45-200mm f/4-5.6 OIS
version ii announced in Jan 2017 offers better weathersealing, and smoother aperture variance when zooming
both lenses can support Dual Sync IS (version I needs firmware upgrade)
90-400mm in 35mm terms
-
very good build quality
16 elements in 13 groups inc. 3x ED elements
7 rounded blades
52mm non-rotating filter
closest focus 1m giving 0.2x macro
70x100mm
380g
$270
-
very well corrected distortions with maximum of only 1% without in-camera corrections
moderate vignetting (1EV) wide open
very good across the field sharpness which is quite consistent for all focal lengths although a slight drop in the longer focal length range
interestingly at 150mm, MTF50 sharpness does beat the Lumix 14-140mm lens at 140mm but not by as much as one would expect
moderate CA at 2px maximum but this is largely corrected in-camera
bokeh quality can be a bit “rough”
overall a solid performance
