非放映的petzval是后面两片分开的玻璃,放映头没有用过,你其实可以找片白墙看看它的投影就知道了。
谢谢520

求大师们谁能帮忙做转接环啊,感激不尽啊


这不是什么大问题,好多可以做的,那些给镜头改口的地方都能做,上海的一水啊什么的都可以干这个,一点不复杂。

是無錯,這些無名的Petzval type老銅鏡在外國多得很,很平宜滴,有些人說接到小数码上用,实在是浪费这么好的镜头。俺亦認為廢物利用,有些老16mm movie camera鏡頭亦是Petzval type 結構.接到小数码上用是不錯的.

As fast lenses were in great demand by the movie industry, TT&H decided to look for a suitable lens design. The old Petzval design was known to be suitable to build fast lenses with very good sharpness in the center of the field. The weak point of the design was the fuzzy borders of the frame, limiting the use of Petzval lenses in photography.

這些老銅頭要大幅機才能表現它的特性

这两个牌子都提供滤镜支架的,这种超大尺寸的滤镜支架无需螺口,建议你去它们的淘宝店看看,一看就明白啦。


谢谢,对于大画幅确实还是比较菜,呵呵

当然可以用中灰镜啊,如果你的镜头口径特别大,可以考虑高坚的X系列,如果只是一般大,那Lee的就ok了。

再问

各位,因为5号快门只有1/60的最高速度

有没有办法用中灰镜,可以在大白天也可以使用这个今天,不然每次都要等到早晚????
