I wanted to post on here about a great product that is out there for the Voigtlander 35mm f1.4  Nokton. I have the official round hood but I wanted to get a square type hood for my street shooting that I do for my personal work.  I am a firm believer in having a hood on all the time not only for light leakage but also for protection. A guy by the name of Bo Lorentzen has made a hood that works really well. I like it a lot better than the round hood that I purchased with my Nokton. I find it does a fantastic job with keeping stray light out of your lens. Note that your lens cap cover cannot be used in conjunction with the hood but I always have my IR filter on the front of the lens so this was not an issue for me.

Here are some photos of the hood on my M8u.
