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.
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。 |
