Scenario 1: 2 Minolta X-bodies (1 for color, 1 for B&W) 35mm, 50mm and 200mm prime lenses with a 2x converter (This covers 35, 50, 70, 100, 200 and 400).
Scenario 2: The minimalist solution - Zeiss Ikonta folder with Tmax 400 and an orange filter and my Minolta light meter. Remove the filter for lower light situations.
Scenario 3: Mamiya C33 with 80mm, 135mm and 180mm and Minolta light meter. The body is a beast but the lenses are surprisingly light. You can't beat the image quality.
