I converted the one above from RAW. Here are a couple in color.Thanks for posting Ron. Would be nice to see some colour ones please Did you do any processing?
loud and annoying sound from aperture in certain conditions... imagine such situation - you try to shoot w/ wider aperture under a bright sun... so parameters are for example, "A" mode, ISO160, f2 and exposure metered to 1/4000... camera can't keep f2 while the sensor is feeding EVF and/or LV otherwise you will not see anything - there is no global shutter, base ISO is too high, readout from sensor for EVF/LV is still 60fps... so camera has to stop the lens down a lot when sensor is feeding EVF/LV... now imagine that you are now making a shot, then camera opens PL25/1.4 aperture wide open to focus (and then adjusts for a shot unless you just focus) and then it has to stop it back down to resume feeding EVF/LV... and that cycle produces quite loud noise w/ PL25/1.4 (in my case GH2 and PL25/1.4)... on top of that PL25/1.4 has quite loud and unpleasant sound when AF for still shot (at least w/ fast focusing GH2 body - which apparently w/ 120fps readout for CDAF can move optics inside faster than older bodies)... so may be optics is great, but mechanics is BAD (sounds-wise... plus all those sounds tells about some extra mechanical wear and tear)What about this great lens for m4/3
my post was not about optics - but about mechanical aspects (aperture and focusing gear) of its operation.Just picked up this lens, but haven't had opportunity to work much with it.
deejjjaaaa's post has me wondering if this was a poor choice, just when I thought I had gotten such a wonderful lens.

I have not detected any annoying sound, in which operating conditions did you hear such a loud sound?loud and annoying sound from aperture in certain conditions... imagine such situation - you try to shoot w/ wider aperture under a bright sun... so parameters are for example, "A" mode, ISO160, f2 and exposure metered to 1/4000... camera can't keep f2 while the sensor is feeding EVF and/or LV otherwise you will not see anything - there is no global shutter, base ISO is too high, readout from sensor for EVF/LV is still 60fps... so camera has to stop the lens down a lot when sensor is feeding EVF/LV... now imagine that you are now making a shot, then camera opens PL25/1.4 aperture wide open to focus (and then adjusts for a shot unless you just focus) and then it has to stop it back down to resume feeding EVF/LV... and that cycle produces quite loud noise w/ PL25/1.4 (in my case GH2 and PL25/1.4)... on top of that PL25/1.4 has quite loud and unpleasant sound when AF for still shot (at least w/ fast focusing GH2 body - which apparently w/ 120fps readout for CDAF can move optics inside faster than older bodies)... so may be optics is great, but mechanics is BAD (sounds-wise... plus all those sounds tells about some extra mechanical wear and tear)
Me neither.....I have not detected any annoying sound, in which operating conditions did you hear such a loud sound?
I am talking about the brand new m43 lens of course.Are you talking about the brand new lens or the old 4/3 lens which indeed was loud.
why 'd I want to use it to reduce the image quality by extra glass surfaces from ND filter, even from a good manufacturers w/ mc, if I still can shoot 1.4-2.0 w/ 1/2000-1/4000 ? I am not talking about making watersurface smooth here...In addition, just any other really fast lens outdoors, if you want to shoot wide open use an ND filter.
from my text that you just quoted (I 'd assume w/o reading it ?) :in which operating conditions did you hear such a loud sound?
