Re: A thinner sensor stack may be possible after all!
TY to Calvin at MF lenses for this interesting overlay
Here Puts compares Elmarit v4 to v3
\"Compared to its predecessor, center performance at full aperture is almost the same. In the field and when looking at very fine details, the current lens has clearly improved optical capabilities. Modulation transfer function (MTF) graphs also show a more rigid correc- tion of the nasty sagittal rays, which blur the rendition of finely graded color hues on small object areas. Clearly, the cur- rent lens is corrected to a higher degree and it is at least one stop ahead of the 1979 Elmarit.\"
I was looking at the astounding MTFs of the 28 cron. For landscape they really look quite a bit better than the 35cron asph.
@Steve OK in that, case I take your point about the confusing nature of what is a zeiss and what is not a zeiss. Loxia lenses are made in Japan, I think. Does Zeiss even own a factory in Japan? Doesn\'t this mean Cosina is building them?
Raises the very interesting question of who actually formulated the FE 35 and 55. They seem to be built from the ground up for the fat stack. The Loxia not at all. Just take our M designs and \"adapt them\". Really?
