The latest update to Flickr’s Terms and Conditions means that it wasn’t possible for you anymore to have a look at or download the sample pictures of my reviews in full resolution.
I spent the last days to migrate all the pictures to one account (not an enjoyable process) and upgraded that to a paid Pro account so that you should have access to the full resolution pictures again.
I now need to update the links to those pictures in more than 200 articles which will surely take some time. In the meantime you can already look up the desired lens directly here.
