I used my Canon 35mm/1.5 with the M9 this past weekend. I used a Canon W 50 lens hood which resulted in some vignetting. Now I think there is no need for any lens hood since the front glass is recessed in the 35/1.5.
I will leave the images without any editing or PS to show you what you get from jpg files.
Handling the lens was easy, but the infinity lock sometimes annoyed me. The M9 has been working very well and without any "going to sleep" since I switched it from discrete mode to standard mode for frame advance.
