Some of you might know that I am learning and testing my cameras and lenses mostly in the garden. No graphs or charts, just plain flowers. Lately I realized that 100 years old ICA A-G produces some interesting results with NEX-F3 assistance. The lens is Carl Zeiss Jena Tessar 1:6.3 F=13.5 cm. It is sharp and contrasty wide opened, excellent performance for the lens that
was designed and built when colour photography even didn’t exist. With APS-C size sensor this lens becomes about 200 mm long but thanks to camera bellows the rig is almost perfect for close up photography. You can see my hack here.
Thanks for looking,

awesome!
ReplyDeleteHow did you determine the focal length to be 200mm ... I am interested in trying this hack myself and trying to figure out what to look for
ReplyDeleteHi Ling,
DeleteI multiplied lens focal length (135mm) by APS-C sensor crop factor (1.5)
