If that works out good, we would not need the push pull flange, this would safe weight, we could go with smaller tubes and smaller dewcaps and together safe many weight for future tubes. But we have to try it first and if we find perfect results, than we may go that way in future.(以后如果镜筒可以足够精确地车制,就可以象zeiss 的APQ那样,直接将镜头通过螺纹拧到镜筒上去,而且可以减轻重量,减轻遮光罩体积。)

这样看来,似乎只有130口径的镜头做了上面所提及的改良,更大的镜头还是原样?
