This rather unlikely setup (combining the sleek new TL with a very old-fashioned lens) was demoed at Paris Photo last week at the Leica space in the Grand Palais. I found the combination curious enough to take a couple of pictures. It may actually be a useful combo, the Summaron coming quite close to being what is called a pancake lens I guess. Anyway, just for your viewing pleasure and reference, something one doesn't see every day.
