Yeah man. Before I knew anything about what all these various items cost, I thought, surely those little lenses, small as pirate earrings, folding flat into the camera, they must be the most rare and valuable of all lenses.
They've been the greatest pleasure for me so far. For my own pictures, reflecting on how much I like something, I factor in how much fun I had taking the picture, and the tiny tessars are so fun...if they produce anything decent I love it.
