Thanks for the reply. It was indeed a grubby day. Sorry to hear it was practically ruined for you and yours.
I am most definitely on the hunt for a new lens. I was previously looking at a 55-250mm IS lens, but if you say the 70-210 is almost L series in quality, I may be willing to sacrafice the extra few feet in zoom ability. It’s also a bit cheaper by the looks of it, so thanks for that!
And thanks for looking.
