Carl Zeiss Jena Biotar 58/2 (17blade-version) disassembly/蔡司 Biotar 58/2 解構
 
08:51
It is not a complete disassembly, just how to access to the glass elements. Unfortunately, the lens doesn't come in good condition: some screws are missing, stiff and/or striped. The Biotar is known for its -unique swirly bokeh -sharpness -symmertical optic scheme

Carl Zeiss Jena 50mm f2.8 Lens Disassembly and Diaphragm Cleaning
 
34:25
Full disassembly and diagram cleaning of a Carl Zeiss Jena 50mm f2.8 lens. This is the M42 earlier zebra style version of the lens. Disassembly is moderately complex, and much more complex than comparable 50mm lens. The major annoyance is that the aperture blades tend to fall out once you remove the front glass piece. Be sure to hold on the diaphragm front layer if you are cleaning the diaphragm. The rather intricate mechanical design also gave me some problems and I needed to add a bit of lubricant to keep things moving well. Full time of video was around 50 minutes. http://photography.mattbierner.com

A wonderful lens. Beautiful wide open with the swirly bokeh it is famous for. My copy is very sharp wide open, with only a small amount ware and tear. The Russians really know how to copy a Zeiss Biotar.

Lens Test: Helios 44M-M 58mm F2
 
01:57
Circa 1970 this made in the USSR lens came as a kit lens on the Russian Zenit film cameras. It's a 58mm F2 lens & it's based on the Carl Zeiss Biotar design. This is a GREAT lens, very sharp, and you can get some cool sun flares with it that you can't get from modern multi-coated lenses. This is an M42 version which makes it easy to adapt to modern DSLRs, I'm testing it on a Canon T31. It can be had for under $50, everyone should have one!
