Hi all,
after reading enthousiastic comments on this forum I decided to treat myself and buy a PanaLeica 25 mm.
It arrived two weeks ago and I tried it on a Olympus E3 with good results. After a long wait my M4/3 adapter arrived and I finally was able to put it on my G1. I updated the firmware and all was fine.
Yesterday I shot some 200 photo's and I think the lens is outstanding. Very sharp and though bulky, not too heavy for me on the G1.
Today I noticed something I don't recall from yesterdays shoot. There is the sound of the aperture closing and opening when I move the camera to and away from a window or other lightsource. I can see the aperture closing and opening as I move the camera towards and away from the window. Now all the time it's in aperture priority mode on f1.4 and when I release the shutter the aperture opens and the exposure is fine.
My question is: Is it normal for the aperture to open and close like this? Shouldn't it stay on f1.4 if it's set to that aperture? Is it some kind of protection for the sensor so as not to get too much light in? Perhaps the kit lenses show this behaviour too, but the noise of the aperture moving is much less? Do other Summilux owners notice the sound of the aperture opening and closing? It's quite loud, much louder than the sound of the AF motor.
Thanks, appreciate your thoughts,
Peter
