I was hoping that the knowledge of this forum could help me out.
I am looking for leica r or contax zoom lens models that donít extend or contract through the zoom range. If the length of the lens changes slightly while focusing it is ok. Manual aperture is also preferred.
Any ideas about what models if any meet these requirements?
It looks like the LEICA-35-70MM F4 may be all internal?
Other zoom lenses from other manufacturers are also of interest to me.
