Sample Images

Finally some sample images taken with the Alpha 100 and RAW converted via LR 4.3. I'm aware that some may prefer Alpha 700 samples but regarding the current workload you may forgive me that I'm using a few samples from my vacation to Kamchatka here.

Verdict

Assuming a good sample the Zeiss 16-80mm f/3.5-4.5 ZA DT is surely a desirable lens. The primary design objective was obviously to maximize resolution because this is where the lens shines with generally stunning MTF figures matching or beating many standard zooms out there. However, there're also downsides. At 16mm vignetting is a problem at f/3.5 and the level of CAs and barrel distortions is very high. At around 700€/US$ the lens resides somewhere between the typical consumer and pro grade zooms. Some may have hoped for a metal construction but truth is that most other standard zooms in this price league have also plastic bodies. The mechanical quality is decent with tight tolerances but nothing to rave about. In Sony Alpha mount the lens remains an obvious choice for enthusiasts and beyond.
