The Yashica Mat 124G is medium format at its most effective, with an 80mm f/3.5 lens fixed to the body and a 6x6 setup. The 80mm is phenomenal as a portrait lens but still has enough breadth in frame to rock some street photography or even landscapes.
The 124G also offers the convenience of 120 and 220 compatibility in-body with a simple sliding of the pressure plate, so the few of us left using Kodak Portra 220 can shoot without worry. Make sure to load the rolls tightly because a loose load can lead to light leaks, especially with 220.
