'With the arrival yesterday of my Leica T 11-23mm zoom lens, I'm once again into the issue of wide-angle lenses and how much 'correction' I do to the files. Because optically, these lenses can prove the most challenging of all, particularly when, as these days, they come in the form of zooms. And while they can provide us with some dramatic results, anyone who has worked with them will know that of all the lenses we have at our disposal, these can be the ones that take up more of post production time than anything else.'
