[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]Leica makes a special correction lens for people with astigmatism (042-253-008). You have to have your optician make up a suitable lens for it. You can rotate the lens within its mount to be able to shoot in landscape or portrait orientation. Most people find it to be too much of a hassle to be fiddling with the orientation of the correction lens all the time and prefer to use glasses or contacts.
