The second one should be something very special and rare, no one seems to know it. The 2.8/180 Sonnar is a huge beast, designed for Pentacon Six, with good picture quality. There was another model, the 2.8/200, which is smaller and definitely better, but a bit rare. Another good one is the 1.8/80 Pancolar. >Does�anyone�have�experience�with�a�CZJ�lens�in�K�mount?�I�want�to� >know:�Will�a�Jena�K-mount�lens�function�just�like�a�Pentax�K�mount?� >Or�like�a�screwmount�that�has�been�affixed�to�a�K-mouint�camera�with� >an�M42-to-K�adapter? Are you sure that CZJ made PK mount lenses? As far as I know, they built lenses only for Exa/Exacta, M42, PB and PSix, and some old and small systems like Altix, Pentina, Praktina. (The so-called "bayonet" CZJ lenses are PB lenses, a mount used on the modern Praktica bodies.) >A�Zeiss�enthusiast�tells�me�that�any�K�mount�Jena�that�I�see�will�not� >be�a�"true"�K�mount�lens.�He�explained�that�Jena�lenses�were�made�with >interchangeable�mounts.�By�this�I'm�not�sure�whether�he�means�that� >there�is�a�universal�base�must�be�joined�to�a�real�mount�(a�la�Tamron'- >s� >Adaptall�system),�or�that�the�Jenas�were�made�for�specific�mounts,�but- >� >the�mount�can�be�unscrewed�and�replaced�with�another�"permanent"�mount. >� The latter is true. They did it so to reduce their manufecturing costs, very few of these mounts were sold separately. Some old teles (2.8/120, 2.8/180) are a bit different, they were designed for use on 35mm and MF as well, and the mount can be changed easyly.
