I was downtown today shooting with my new Leica and just as I snapped the shutter on this one a rent-a-cop came half running down the street shouting "No Pictures! No Pictures!
I'm quite interested in your Leica experience because I'm hoping to soon get some Leica glass. Do you use medium format at all? I have read that while yes, Leica is great, almost any MF will give you greater quality. Can you comment based upon experience on this?
As for the copyrighted building, if indeed it is copyrighted, you should still be able to photograph it, you just cannot publish an image of it for profit, no?
I use Leica lenses a f2 90 mm APO Summicron and 35mm f2 APo summicron on a M7 and the results ( with proper processing) are truly stunning.
I am just printing some Fuji Acros to 20" x 16" and they are very sharp and almost grain free.
Let's do the math. A 35mm negative needs about twice the enlargement of a MF negative. As long as the 35mm has twice the resolution of a MF, there shouldn't be a difference, regardless of print size. Does a Leica lens have twice the resolution of a Hasselblad lens? Of course, if the magnification is small, neither negative will be enlarged enough to reach the threshold of human detection (7 lp/mm) and the prints from both cameras will look identical. This is why many see a huge difference between 35mm and MF but don't see an improvement when moving to LF. They don't make prints large enough to see the difference!
