Dates from August 2009, but specifically states:
"Furthermore the P 65+ is not recommended with extreme wide non-retro focus lenses like the Schneider Kreuznach 35mm XL and even the Schneider Kreuznack 47 mm XL
Even though these lenses has more than 70 mm image circle, they are producing a very steep angle incoming light along the edges, occasionally causing thin lines to show up in the image. Note that this can also occur with the P 40+". <<see attached image>>
I mention this not to raise a red flag, but to say that I never have experienced this phenomenon. Using a 24mm SK XL and 35mm SK XL with my Cambo RS I have never had the lines show up with moderate rise or shift. Can't remember any of you mentioning this, but wanted to throw it out there. Anyone experienced this?
