45mm Pentax 6x7: a great lens with a bigger neighbor
A super wide-angle with great performance, but with a bulky neighbor and an undeserved reputation
The Pentax 6x7 lens series has been the flagship of the Japanese house for over 50 years. The first company to invest in 6x7, a format that combined the aspect ratio of the optical bench and the portability of the medium format, the 45mm is the widest-angle lens ever produced for it. Actually, there would also be a 35mm, but it is a fisheye, which, therefore, we are not going to analyze.
