Leica mtf graph

[Duff photographer]

Howdo,

While one can download pdf files of the MTF graphs for the newer R lenses from Leica's website, I can't find one for the Apo-Telyt-R 280mm f2.8 [11263] which ended production in 1996 (to be replaced by the modular 280mm).

Google has not been my friend in this regard, so does anyone possess or have a link to such a file?

Ta.

Duff.

Ah, of course!

(a few moments later)

Seems that Leica have eradicated all traces of the 280mm f2.8 upon the introduction of the modular version, and I now have the growing suspicion that there was never a publicly available PDF of the lens' MTF, as the lens was discontinued just as the internet was getting going. Photodo did their own MTF test of the lens, but there is no test of the 280mm f4 or of the f2.8 modular version to directly compare it with.

...and I'm not going to bother Leica with a request, so I shall leave it there.

Thanks Paul.

Cheers,
Duff.
