I-61L/D 后面那个L/D就是镧系的意思吧。
欣赏！这个资料很好。收藏了。:victory::victory:

估计苏联的I-50镜头也用了较好的玻璃？分辨率指标与I-61相近。个人感觉早期的熊猫版I-61的质量好像更好。 ...
假如严格来分的话，我认为所有茵-61（不加后缀的）都是熊猫（或斑马）版的，银白的是茵-26M，而黑色的都是加了后缀L/D的茵-61后期型。

加了后缀L/D字符的是否用了澜系玻璃，这个真不好确定，似乎目前还没见到官方直接的证据吧？
其实那个时代很多镜头都用镧系玻璃，佳能、宾得都有。

我的印象中后期的I-61 L/D 也都是用了镧系玻璃镜片。我看看在那些苏联相机网站能否找到出处。
你说的有道理。好像早期的I-61都是熊猫版的。

就这个贴内镜头而言，不带L/D ，但从那纸片看是镧系玻璃

This lens replaced its predecessor Industar-26m as a standard lens on the FED-3 and all later FED cameras. The optical design was improved, and a new, Lanthanum glass was used (letter L is for Lanthanum, D is for Dal'nomer - Rangefinder.
This is the newest multicoated LTM lens made by the Soviet (now Ukrainian) photo industry. It is sharp and contarsty, with smooth focusing action and the aperture click-stops.
It is still in production by FED factory in Kharkov, Ukraine. The lens was also made in universal 42mm mount for Zenit cameras, its name was Industar-61L/Z.
在USSRPHOTO.com 网站找到的一段介绍。 l说明是用了镧系玻璃。D的意思是旁轴相机用的。而且I-61还是多层镀膜的镜头哪。

根据以上说法，I-61 是多层镀膜的，用了镧系玻璃的镜头。L表示用了镧系玻璃，D表示是旁轴相机用的。

从那片发黄的纸片上看，上面标有镜头编号，是07开头的早期茵-61。恰好我手里有02和09开头的各一枚，由于07位于02和09之间，所以由此推断，07开头的茵61应该和我手里的是同一种款式。换言之应该是52mm焦距，最小光圈F22的那种第一款斑马镜头。
