We are discussing PRIMES vs ZOOMS. Any argument that zooms are less complex than primes zooms is very incredble and pretty dumb if you ask me. Zooms have to have more optical and mechanical complexities to be ABLE TO ZOOM. the mechanical complexities of zooms negatively affect the optical quality too. I am not going to buy what you are trying to sell me or anyone else, not for a minute....
