I was taking photos of my kid yesterday and 200mm just wasn't long enough. I've been thinking a long time about a 300mm or 400mm but I'm afraid I won't really be able to use it because it's a bit too loud. I'm sure you can all imagine how sensitive some parents would be if one parent was sitting on the side with a big white lens.
I'm wondering if anyone here owns a 300/400 and takes it to family type events and if so, if they've felt it was "impolite" in any way. I'm thinking mostly photos for my young kid (swimming, sports when gets older, plays, etc.).
