Hi Carlos, > The Rolleiflex TLR has been produced along 80 years, more > the double of the time than your 500.- The 500C was introduced in 1957. That would be 52 years, significantly less than "double". If you included the 1600F, which would only be fair, since you are including ALL Rollei TLRs, the Hasselblad MF SLR model has been produced since 1948, or 61 years.
