The walimex pro 135mm standard telephoto lens is an excellent workmanship and the lens mount precisely. Although it is a bit difficult, it is very comfortable to hold and can be manually adjust well, whatever is required since it has no autofocus. I have used it mainly for portraits in low light conditions and these have become really great. But even landscape shots at close range are no problem for this lens and allow completely new effects arise. I am very pleased and look forward to further experiment with it :-)
