I have a 66 and super 66 with 4 lens, the 55, 80, 150 and 250, have both the eye level and waist level prims. Bought mine in the early 80s just after Kowa left the market, my intent was to upgrade to a Rollie 66SL, needless to say the Kowa's worked so well never saw a need. The lens stack up well against Ziess. Only drawback is that in order to change the film or the back on the super you need to take the camera off a tripod. There are older chrome lens and newer black lens, the black lens have a better reputation. Just for information, Ross Yerkes has a reputation as an anti-Semitic and racist. he must be in his 80s, dont know if his shop is still open. Just remember these cameras are now over 40 years old, not make in large numbers, keeping them up and running, well that is a challenge.
