The specific reason for asking this question is that I'm looking to purchase an Ihagee Parvola 3x4 cm camera. I have a choice of two. One has an Anastigmat 70 mm lens and the other is a Tessar 70mm. The price difference between the two is significant. The camera with the anastigmat lens is $80.00 cheaper than the one with the tessar lens. I will be using one of these cameras for everyday street photography and I just needed to know which is the better lens for rseolution and sharpness.
