I am a new comer to the Leica M system. I have enjoyed my Leica R slr system and recently purchased a Leica M4P. I would like to add a 35mm to the M series and wonder if someone has some helpful first hand experience with the affordable Voightlander 35mm f 1.7 Ultron or the 28mm f 1.9 ultron ? I would certainly appreciate if someone who has used these lenses would give some input as to the quality of the images taken by these lenses; perhaps some pro and cons and pitfalls if there are any with the support and service of these lenses. By the way, I am writing from Ontario, Canada.
