Heylo POTN,
So I'm probably about to pull the trigger on a 24-70 L f/2.8 Mark 1. Not too worried, and I'm not exactly understanding the whole date code stigma yet, but the lens I'm looking at begins with US11. I take it that means it was made November of 2004? Were there any manufacturing issues or anything with the 24-70 f/2.8's back then? Is the lens likely to be soft or anything? The previous owner said that it had minimal use and that's why he's selling it.
Just wondering!
Thanks.
