找到点关于C T*镜头的英文资料。

暂时没有时间翻，先搁在这里。原文的完整版下载http://rob168_com/camera/Hasselblad.txt

6.  C T* lenses
---------------
These lenses are essentially identical to the C lenses, except that they have
six layers of coating to reduce flare and improve contrast.  The term "T*"
(pronounced "T-star") refers in general to all Carl Zeiss lenses with this
multicoating, not just Hasselblad C T* lenses.

The question often arises about the differences in image quality between the
C and C T* lenses.  The consensus seems to be this: in situations where sources
of flare are absent, a C lens with appropriate lens hood will produce images
that are slightly less contrasty than its C T* counterpart.  In some cases
the images may be indistinguishable.  In situations where there are sources of
flare (especially flare with wide angle lenses), the C T* produces noticeably
better quality.

C T* lenses are black, except for the very earliest T* lenses which are satin
chrome.  These lenses have highly scalloped focusing and shutter speed rings,
and have the words "Synchro-Compur" etched on the side.

The T* designation is inscribed in red on the front of the lens barrel.  During
times of transition, such as going from the 500C to the 500C/M, it is not at
all unusual in manufacturing environments for an upgrade to be implemented but
not be so designated.  This is the case with late model 500Cs that are really
500C/Ms.  Similarly, it is possible that some lenses have the T* multicoating
but are not marked as such.  Conversely, it is possible, though not very likely
or very common, for an older non-T* lens to have been repaired and fitted with
a newer rim having the T* designation.

The first Hasselblad lenses to get the T* multicoating were the 30mm, 40mm, and
the SWC's 38mm Biogon.  The 80mm/2.8 C T* appeared in late 1974.  By the end of
1976 most of the C series lenses were being produced in multicoated form.

The 140-280mm Variogon of this period is not designated a T* lens because it
was made by Schneider rather than Zeiss; it was, however, multicoated.

唉,我不玩了,出全套,做个广告。

五一前拍的片子，今天刚拿到。回头有去扫描，就上几幅来讨教。

小狼主啊，这里太热闹了。怎么没有见你的作品啊！

呵呵，你们下去确实早了点，后来天空开始慢慢放晴时，站在亭子看古村及背后山顶的云层变化很漂亮。可惜大幅就是慢拍了几张就云开雾散了，哈苏也没来的及拍.就在这上一张612拍的，可惜曝光没调好（后期也不行^_^），将就看看吧～～

哈哈，幸会幸会，原来是你们，印象深刻，偶一大早跑到山上亭子里，遇到大雾，很是失策啊，不过，看到你们一溜烟的大画幅，口水哗啦啦流。无奈只好进村拍点小品，可等太阳高照时，俺望了望山头的方向，实在没有力气再返回去拍了，留下无数的遗憾。那里能欣赏到你们用大幅相机拍的流坑全景？到时能否在这里给一个链接，俺也好弥补一下缺失的美丽。握手！

呵呵，我们在古村后面的山上亭子里见到的，当时我忙着玩大幅，但看见你架子上的哈苏，再看见你发的这几张片子，一查你是福建的，就估计是了，哈哈哈

江西流坑小品：

实不相瞒，我那个80标头，据老哈苏DX查看后认定就是拆修过的。我买来后拍片无数，肉眼看不出与未拆修镜头的区别。

晕，我没那么老，别喊前辈，叫小狼就OK，不然让人笑话我，呵呵。
前压圈就是你说的那个，好好看看上面的两个小缺口。

这个是哈苏C 80 T*头，但与早前的C头又有所不同。这个C80是哈苏501C套机的标配镜头，外观上跟CF80几乎一致，只是快门少了个F档——可以说是CF头的简化版，但镜组结构一致，在500系列机身上使用没有什么区别。
镜头有没有拆过，主要看后接口的螺丝和镜头前压圈有没有动过的痕迹。哈苏镜头遮光罩接口处容易掉漆是尽人皆知的，不必挂心。
即使是拆洗过的镜头，只要是专业维修，成像不会有质的影响，但完全没影响恐怕不可能。试一下无限远时是否合焦，再拍几卷反转片看看成像如何吧。

镜头外表是很新的～
