thanks. glad to know. I have no idea about the standard contents. then I can keep it. about to return it but nice to get info as I really like it. this is my first DWP lens.@vmaniqui I think the bag is like that because they are part of the SI standard issue line. I found a bunch of them online and some people trying to buy the same cloth in this forum. I got mine yesterday and I believe they are legit.
