ZV have 50/4, 120/4 and 180/4. they don't have 150/4. in fact, 180/4 only have CF version. pls compare the focus ring, depth of view button, shutter speed and aperture ar moving individual. that is CF design.
150 or 180 is very personal taste. c 150 is smooth and have more highlight detail. and 180 is sharp and vivid.
if shooting a model, my 180 will work with softer I. it will reduce the contrast and have better and smooth tone.
if i wrong , pls point it out:
the number of coating in CF is 7
the number of coating in CT is 6
more the number of coating, more contrast and vivid.
dim light and soft slide will be better work with CF
strong sun light and contrast slide will be better work with CT
so what kind of lens, films and light source all need to work together to have good result, right.
at last, CFi is using recycle glass and CF and CT not. Only one thing i don't like CF len is the silk print marking. So easy to lost them.

以前c鏡的用料(玻璃材質)鏡筒(全金屬)及快門(鋼片快門)都是集最優廠商及等級零件,70年代生產產品是以耐用及高素質為考量,如nikon當時的F2,canon F1等機身到現在依然精確耐用,以當時售價一支全新150mm鏡頭約nt.38,000以35年的等值貨幣現在一支約要15萬以上,前一陣子哈蘇出3顆記念鏡50mm,80mm,150mm 以c鏡為復刻全金屬每一支鏡頭超過15萬台幣,如果cf好於c鏡,哈蘇就不會以c鏡為復刻籃本,另哈蘇鏡頭全勝時期是cT*時期,它的鏡頭柔中帶利尤其暗部比cf鏡乾淨許多,反差也不像cf鏡高,立體感強,
Some comment CT* better than CF version as the above
