This lens puzzles me more than any other. While there are not many photos out there taken with it (at least I couldn't find many), in some it seems to have a very ordinary signature, not very sharp, kinda "blah" look. Others - it's very sharp, with element of being 3d look. On the cameraquest site there is a reference to a Pop Photo test where this Heliar was rated as good as Summicron, but I don't seem to see it in most pics. Is it a user errors than? Is this lens so difficult to handle that it's hard to get good results from it for most users? Or is it sample variation - some are excellent and some are poor?Or am I not seeing something? I'm very intrigued by this lens, so I'll probably have to get one to test it for myself. But I wonder what's user opinion in it?
Any thoughts?
