Hi, I've had this lens for a while now and its not one I use too often however I noticed the other day that in shots I used it for that it is showing exif data of 105mm and not 100mm when used on a 1Dx. Previously it had been ok and showing at 100mm, I've just checked it on my 7D and it is showing as 100mm. I've not come across exif data being misread before, anyone else seen this with either this lens or any other? Not the end of the world but just a query.
