Hello - I've been lurking here for some months and decided to join the fun.
A little about myself: I have been a 4x5 and 617 panoramic photographer for many years (mostly landscape); I have had a Canon DSLR for a long time, but never for "serious use". When the 5DSR was announced, I preordered one with the thought that it might be good enough for me to give up shooting film with 4x5 and 617. After weeks of testing, I decided that it would replace my large cameras, which are now being sold.
I'm in the process of replacing most of my older Canon lenses with Zeiss primes. Here are a few images from the flower garden, using the 135/2. It's certainly a marvelous lens and I see myself using it frequently!
EDIT: 3 photos immediately following this post.
