Two quality prime lenses pretty much cover most of my needs. Plus one macro lens. I do 70% of stuff with a 24 to 70mm equivalent. There was a time when a zoom for a Bronica SQA was inordinately costly so there were, practically none out and around, and just dream stuff for the average guy or gal, Aspherics and computer design has made zooms just great, and the good ones are almost affordable. And the fixed FL is a blessing for any user of flash indoors.
