Ich
habe es sehr pfleglich behandelt, es kam als Zweitobjektiv bei Aufnahmen mit zwei gleichen Kameras nur relativ selten zum Einsatz. Ich verkaufe es nur wegen
Formatwechsels.
Leica hat ein Superzoom der
Spitzenklasse gebaut mit Auflösungen in verschiedenen
Brennweitenbereich, die manch ein Vollformatobjektiv nicht erreicht.

Below is a simplified summary of the formal findings. The chart shows line widths
per picture height (LW/PH) which can be taken as a measure for sharpness.

Die Tester von Photozone sind sich einig: dieses Objektiv würden sie auf
eine einsame Insel mitnehmen, wenn sie nur ein Objektiv mitnehmen
dürften:
Verdict
So is the Leica 14-150mm f/3.5-5.6 OIS
THE LENS you'd take that
that lonely tropical island (if you could take just one) ? Yep, it could
be the one although it's not totally flawless but then no lens is.
However, it is both sharp and contrasty throughout the range - in fact
it's far more harmonious than any other similar lenses tested to date
here. The level of barrel distortion is very high at 14mm whereas the
problem is basically negligible at other focal lengths. Vignetting is
also very well controlled except at 14mm f/3.5. The only real weakness
are very strong lateral CAs at both 14mm and 150mm. This is correctable
but out-of-the-box this can be disturbing. The quality of the bokeh is
decent for such a lens although the effect is naturally underdeveloped
due to the small max. aperture. The build quality is very high but we'd
wish to have a dust sealing in this lens due to the air "pumping" (thus
dust sucking) during zooming. The AF works virtually silent and it's
sufficiently fast - just don't expect it to be a speed daemon.
Panasonic's Mega OIS seems to be less efficient (~2 f-stops) than
Canon's IS or Nikon's VR. All-in-all the best of the breed within the
"super" zoom lens class at this stage and as such possibly also worth
the very high price!
