I hope I can get some intel from you folks. I currently have a 18-55mm on my X-E2S that I carry more or less all the time when not with my SLR. I'm looking at adding the 10-24mm which has similar design and operation. I'm looking to buy a used example so looked on MPB's website (UK) and find 51x of the normal and 15x or the WR version. So this prompts the question what's wrong with these lenses? If there are so many available is there an issue to prompt owners to trade them in?? Virtually all the examples offered are classed as 'Excellent' which suggests a limited use life. What could be causing this glut so am interested to hear about experience and recommendations from users and previous owners. Many thanks in advance
