I've had one for about 4 / 5 months, Yeah I like it though I do find it a" little soft at the far end" but no problem really Some of the early ones did have a bit of an issue when in portrait mode These has a 0 or 1 as the third digit of the serial number. So just make sure that you are not buying old stock, and as Paul says the 75-300 is a lot cheaper but no where near as good from what I could find out when I was looking in this direction
