Images captured by today's digital cameras are of such high quality that it is virtually impossible to see the differences revealed by our tests in print. To help you judge the results of our tests for yourself, this archive includes a full-resolution ISO bracketing sequence of our lab test scene captured using the camera models covered in the text.

This issue's lens tests takes a close look at manufacturer's own-brand and third-party wide-angle prime lenses and a range of Canon lenses used with the ultra-high-resolution EOS 5Ds R. This archive contains the high-resolution JPG and RAW test shots we captured fotr both articles.

This ZIP file contains sample images from this issue's article on using telescopes as telephoto lenses. The images were captured over a period of several weeks, so weather conditions varied from batch to batch. The results nevertheless provide a good impression of the performance of the lenses and telescopes we tested.
