Just tried my newly acquired Elmar 135mm on a boat trip crossing the Bosporus. Some of the images were taken on a relatively calm sea, but an old passenger boat with considerable engine vibration and with a handheld M8. Minor treatment with CS4, absolutely no sharpening. The b+w images were in-camera processed jpegs, with just a little boost in contrast.
Criticism most welcome.
Cheers from Istanbul,
