I purchased a new Leica 50mm f1.4 last weekend. When I tested focus in the shop it focused spot on at very close distances around 1 meter. I thought that this would mean that the focus would be fine at all distances. However trying the lens over the week has shown that it back focuses when I attempt to focus on things more than a few meters away. I am going to try a new lens when one is available in a few weeks.
Is this focus problem at different distances a known issue with this lens?, or is my copy a dud? What are your experiences? How can Leica let such a top of line lens out of the factory without making sure that it works properly?
I must admit that the images taken over the week suggest that when you get the focus right the 50 lux can be a fantastic lens: the color, out of focus render, sharpness, etc is very nice indeed. I so want to find a copy that will work well.
Thank you for any thoughts!
