I had the Panasonic 100-300, 45-200, Olympus 40-150, 14-150 and still use the Pana 45-175 and Oly 75-300.
At 150mm the Olympus 75-300 is the sharpest, the Pana 100-300 is good, too.
All autofocus mFT-lenses do that.
Focussing is done by micro-motors, that needs battery power.
The aperture is controlled electronically, there is no mechanical aperture lever like in Nikon AI...
I own the Voigtländer for some time and find it near perfect for portraits for the same reasons ...
At F0.95 or 1.2 the rendering is very smooth, the sharpness is there, but it has a mild, pleasing...
Yes, mirror flap it was called :-D
Actually I don't find the "shutter shock" issues very important.
It's usually at 1/125- 1/200 sec, mechanical shutter speeds, with some rather light lenses.
The 12-40 is sharper than the 2.0/12. At 12mm it's near perfect.
The 2.0/12 has three advantages:
1. it's smaller and lighter
2. it doesn't flare or rarely produces reflexes in back lighted shots...
Great pictures :)
I'd love to see more pics of your country.
Your 12-40 is very, very sharp and renders the scenes beautifully.
Thanks, I am curious :)
Well, ISO 6400 is hardly useful to get an impression of the sharpness.
Could you take some pictures under better lightning conditions at ISO 200 ?
If you have a look at the sample shots in the test at lenstip.com
e.g. here: http://pliki.optyczne.pl/oly12/oly12_fot09.JPG
you can see that the edges (green gras) are sharp from corner to...
Sharpness in the corners seems to be too low.
I have used the Oly 12mm for some time now and I haven't had any landscape shots at F5.6 or 6.3 with similar problems near the edges.
Maybe you have a...
There is certainly some sample variation with both lenses.
I had both lenses for testing and the Oly 14-150 is a good superzoom but there is some fall-off in sharpness towards the edges of the...
I have bought a Metabones Speedbooster, too
It's great to gain one F-Stop and the best matches so far are the Nikon 2.5/105 (-> 1.8/75)
and the Carl Zeiss Sonnar (converted to Nikon Ai) 2.8/135 (->...
1/160 sec, OIS on, IBIS off.
I assume it's caused by shutter shock.
IBIS on and OIS off gives similar results.
The shutter speeds that cause shutter shock with this lens are highly dependend on...
I'm using the 14-140 II on my OM-D E-M5. The lens OIS has a problem with speeds around 1/160 sec, sometimes I get blurred images at that shutter speed with OIS on.
Other shutter speeds are fine,...
I have a Panasonic GH2, G1 and an Olympus OM-D E-M5 in use, so it's easy to compare the jpeg characteristics for me.
In one sentence: Panasonic jpegs are inferior.
They usually have a yellowish...
Probably needed for FT lenses and PDAF.
CDAF doesn't need AF-adjust as far as I know.
Yes, I am also not aware of any F2.0 zooms for mFT.
The only fast lenses from third party manufacturers are primes, like the Noktons from Voigtlander (0.95/17 and 0.95/25 so far), Schneider...
