Carl Zeiss Jena f/4.5-5.6 MC Macro JenaZoom 75-300mm (top)
Another fairly recent acquisition; a 75-300mm Carl Zeiss MC Macro Jenazoom Super f/4.5-5.6. The mount is for the older Canon FD system and fitted with an adapter to mount onto an EF body. This means that the lens is entirely manual.
These are not especially common lenses, and although they do not have the same quality reputation as (e.g.) my Planar T* 50mm (with which this was taken) - I believe they suffer from an unnecessarily mediocre reputation. I am very happy with my early test shots from this lens & I look forward to posting some shots taken with my small collection of Zeiss lenses.
